The Phenomenology of Anomalous Experience: Perceiving the Human Energy Field A thesis presented in partial fulfillment of the requirements for the degree of Master of Arts in Psychology Massey University, Palmerston North, New Zealand Rochelle Cooper 2003 Abstract The construct of an energy field or aura surrounding and/or interpenetrating the human body dates back at least five thousand years, and is a cornerstone of many ancient and contemporary healing approaches. Belief in, and reports of aura perception continue to be widespread across a large number of cultures in contemporary times. Despite increasing public interest and popular press publications, little attention has been paid to this topic within mainstream psychology. Even within anomalistic or parapsychology, most studies have been limited to investigating rates of reported belief or experience. There appear to be no studies in the literature which map the phenomenological features of this experience. A four model framework suggested by earlier researchers is used to synthesize and review both academic and non-academic literature. Explanations for au ra perception from the perspectives of the Psychical Model; the Scientific Model; the Clinical Model; and the Aura Imagery Model are considered. Interpretative phenomenological analysis was used to investigate in depth reports of aura perception in twelve subjects, in order to explicate the parameters of claimants' accounts, and chart the textural aspects of their experiences. Four master themes of 'The Phenomenon', 'Perceiving', 'Sharing the Experience, and 'Making Sense of the Experience' emerged from the analysis as being core aspects of the phenomenology of aura perception. Findings are considered alongside the four-model framework in order to suggest the most profitable direction for future research on this topic. Further investigations paralleling those used in the study of synesthesia are recommended, along with examination of the possible relationship between empathic sensitivity and aura perception. 11 Acknowledgements This study could not have taken place without the generosity of the twelve participants, who willingly gave up their time to share often deeply private experiences.

INTRODUCTION The construct of an aura or energy field surrounding and/or interpenetrating the physical body is a cornerstone of many ancient and contemporary healing approaches, and is central to understandings of person hood and spirituality in many cultures. People all over the world have reported perceiving auras around others throughout the centuries, and the existence of auras has been asserted by mystics and postulated by philosophers and scientists. More recently there have been claims that their existence is able to be demonstrated with newly developed technology. Such claims make up part of a greater collection of reported anomalous experiences which have been dismissed as topics of serious study from orthodox psychological inquiry and left to the domain of the somewhat marginalised sub-specialty of parapsychology. Even within this sub­ specialty, reports of the phenomenon of aura perception have attracted little attention, meaning that such experiences remain largely unexamined by a discipline which purports to study the individual. This is undoubtedly due in part to a lack of verification meeting traditional scientific standards that there exists an objective external energy field surrounding human beings, but also because such reports often assert a spiritual dimension to this construct, contesting traditional empiricist assumptions about how human beings function in the world. A premise underlying this study is that there is greater value in a discipline that is open to the examination of reports underlying folklore and cultural beliefs, than one which dismisses constructs and indeed whole areas of human experience a priori because such things cannot have validity under the prevailing scientific paradigm. The value of such studies should not be weighed solely on results confirming or contradicting existing understandings of scientific laws, but also on how they contribute to our understanding of what it means to be a human being. It is suggested that psychology as a discipline has progressed 1 sufficiently within the last decades to reexamine claims of such phenomena with matured epistemological and ontological premises, and with a greater range of methodological tools. Making the need for such a reexamination more compelling is the increasing, but often uncritical public interest in anomalous experiences in general, and in the construct and reported perception of human energy fields in particular. Despite a historic avoidance of such topics, psychology is uniquely positioned and qualified as a discipline to undertake such a reexamination. The following introduction begins by locating the construct of the aura within time and space - a necessary consideration given this construct is surprisingly ancient. A brief history of the study of anomalous experience in general within psychology is then considered, this being a sensible and inevitable starting point for a review of studies pertaining to the human aura. Conceptual frameworks for considering aura research are then discussed, and provide the framework for discussion of both academic and non-academic material which follows. This inclusion of material from beyond modern psychology was considered necessary in order to sufficiently contextualise this phenomenon and it's study, given there has been little academic treatment of this subject within the discipline. An explanation of the aims and objectives of the current research concludes the introduction. While many individuals and traditions would extend the existence of an aura or energy field to animals, plants and even non-living things, the focus of this study is specifically on reports of perceiving the human aura. The terms 'aura' and 'human energy field' are used interchangeably, reflecting the label used in folklore and the older, more mystical traditions, and more modern approaches to the subject respectively. The term 'aura' is also used in neurology to label a variety of subjective experiences reported as immediately preceding various types of migraine and epileptic activity, including deja vu and somatic or olfactory sensations. The neurological meaning of this term should not be confused with the subject of this study. 2 1.1 History of the Construct of the Aura The claim that humans are enveloped in a radiating luminous cloud surrounding and/or interpenetrating the body is not a new one, and this construct appears to have been part of many cultures' beliefs and traditions for millennia. Sacred images from early Egypt, India, Greece and Rome used this convention before it became so popular in Christian art, and before the aura was considered an attribute of everyday mortals. The most often quoted source of the oldest recorded reference appears to be the Upanishads, ancient Hindu Vedic texts over five thousand years old. They speak of a universal energy called prana, which moves through all forms and gives them life. These texts also refer to points on the body called chakras, a Sanskrit word meaning literally 'spinning wheel', where energy is thought to enter and leave the aura (Brennan, 1987). These constructs have informed Indian spiritual beliefs and healing practices for thousands of years and continue as part of Indian understandings of health and illness today. In the 3rd millennium BC the Chinese also proposed a similar vital energy called Ch'i, which comprised all animate and inanimate matter. Ch'i was also conceived of as containing the polar forces of yin and yang, and of moving through the body in meridians, or streams of energy (Brennan, 1987). It is upon these constructs that the ancient practices of acupuncture and reflexology were founded and continue in the present day. The construct of the aura continues to be part of cultural understandings in contemporary times. White and Krippner (1977) compiled a list of 97 cultures that have references to auric phenomena using 97 different names. This suggests a universality to the experience of perceiving the human energy field, or at least the sharing of a common construct, in 3 addition to the historical references to the aura dating back five thousand years. 1.2 The Study of Anomalous Experience Psychological interest in anomalous experiences dates back to the inception of the discipline at the end of the 1800's, when investigation into such experiences was pursued personally and professionally by some of the founding figures of psychology such as Carl Jung (1965) and William James (1902). The Society for Psychical Research was founded in London in 1882 with the purpose of investigating such experiences from a scientific perspective, and three years later the American Society for Psychical Research was founded in Boston by William James, amongst others (Griffin, 1997). However, as psychology sought to align itself with the natural sciences and behaviorism became the prevailing hegemony, 'religious' and even subjective experiences ceased to be the subject of proper psychological inquiry. While the 'turn to cognition' has reestablished the respectable study of subjective experience, reports of aura perception , contact with the dead, near death experiences and claims of other such phenomena continue to present a challenge to the discipline. The use of the term 'anomalous' in psychology is quite recent, being proposed by anthropologist Roger Westcott (1977) to prefix the name of the discipline that dealt with paranormal phenomena. This term derives from the Greek 'anomalos' meaning a deviation from the common rule, type or form, or something abnormal, incongruous or inconsistent. That which is anomalous is in contrast to 'homalos', or that which is the same or common (Cardena, Lyn & Krippner, 2000). An anomalous psychological experience is therefore one which will "contradict commonsense or institutionalized (scientific or religious) knowledge" and is "anomalous to our generally accepted cultural storehouse of truths" (Truzzi , 1971, p 637). 4 The importance of this name change, both in reflecting and changing attitudes about the study of such phenomena, should not be underestimated. Previous terms reflected quite literally the schism between mainstream psychology and the sub-specialties which studied such experiences - 'parapsychology' and 'paranormal' are both prefixed by a term meaning beyond; 'supernatural' means quite literally that which is over or above the natural. The study of such things has therefore largely been considered as beyond, over and above the discipline of psychology. The newer term reinstates the study of such phenomena within mainstream psychology, allowing for a reexamination and greater cross-fertilization of ideas and research findings. Belief in and reports of Anomalous Experience As the following collection of studies show, anomalous experiences are reported as reasonably common within the general population and appear to be made sense of within existing cultural beliefs and folklore. In 1974 in the United States a community mail survey of psychic experiences completed by over 600 students and townspeople in Virginia found claims of psychic experiences were widespread, with over half of the respondents reporting at least one extra-sensory experience (Palmer, 1979). Over fifteen years later a Gallup national survey on belief in paranormal phenomena among adult Americans produced similar evidence of widespread belief, with over half of the sample asserting a belief in extra-sensory perception, and a quarter in clairvoyance and ghosts. A quarter reported having had a telepathic experience and one in six reported having had contact with the dead (Gallup & Newport, 1991 ). Haraldsson (1985) found comparable results in European countries when he gathered findings from a number of large representative surveys carried out in the 1970's and 1980's containing questions on belief in and experiences of psychic phenomena. While different response alternatives and translation difficulties complicated the 5 comparison of data across countries, there was similar evidence of widespread belief in the existence of psychic phenomena. For example, the majority of respondents in the Icelandic, Swedish and Great Britain samples believed in the validity of psychic dreams. In Iceland, Great Britain and the United States at least 60% of subjects reported personal psychic experiences. A representative survey conducted in Scotland investigated the incidence of what is known locally as 'second sight', a term referring to a variety of prophetic visions or symbols which are perceived spontaneously and often relate to events such as accidents or death. Reports of such experiences ranged from 10 to 33% across four geographical regions (Cohn, 1994 ). Those reporting second sight in family members were significantly more likely to report having second sight themselves, even when relatives were restricted to blood relations. There is a long Celtic tradition of reports of second sight, which is generally accepted in these areas as a natural ability and believed to have a familial tendency. New Zealand data on anomalous experience is scarce, with only one study located which reported comparable phenomena (Clarke, 1991 ). This was in a non-representative sample of 1048 internal and extra­ mural university psychology students asked to indicate their degree of belief in and experience with 17 paranormal and religious phenomena. Results showed that overall more than 80% of the sample believed in at least one paranormal or religious phenomenon and 60% reported having had a paranormal or religious experience. A further qualitative study by the same researcher (Clarke, 1995) found that personal experience with a phenomenon, and influence of significant others' reported experiences were the most important contributors to belief in such phenomena. While it is important to note these surveys dealt with reported but un­ investigated ostensible psychic experiences, these results still tell us much about the degree of acceptance of such beliefs within mainstream 6 culture in a number of western nations, and the frequency with which subjective experiences are labeled in this way. 1.3 The Study of the Human Aura Although much has been written about the aura in popular and occult literature, the most notable feature of academic literature pertaining to this phenomena is it's scarcity. Searches conducted using the PSYCINFO data base (1887 to December 2001) with 'human aura' and 'human energy field' as mapping terms produced only 17 references in total, with four of these for publications prior to 1940. While it is not surprising to find literature on the aura hardly features within mainstream psychology, there is also little specific mention of this phenomenon within the anomalistic or parapsychological literature (Alvarado & Zingrone, 1994 ). For example, there is no specific discussion of the aura in Reed's "The Psychology of Anomalous Experience" (Reed, 1972), nor in the most recent comprehensive review of studies of anomalous experience (Cardena et al, 2000). Many of the references to auras found in extended literature searches were in relation to wider studies on the prevalence of beliefs in the paranormal and the incidence of such reported experiences. Belief in and Reports of the Human Aura Haraldsson's (1985) Icelandic sample found 7% of women and 3% of men reported having experienced this phenomenon, averaging 5% for this representative sample. One third of the sample said they could do so voluntarily (as reported in Gissurarson & Gunnarsson, 1997). Palmer (1979) found comparable results in his community mail survey with 5% of residents and 6% of students reporting this experience. Alvarado and Zingrone (1994) compiled incidence rates for a number of studies, showing randomly sampled groups have reported incidences between 0 and 28% - the latter for members of a tribe in a remote rural community in the Philippines. Non-randomly sampled groups have reported a higher incidence of aura perception, ranging between 9 and 47-48%. 7 These latter two groups were members of the Association of Research and Enlightenment (a group dedicated to the work of renown American psychic Edgar Cayce), and a group of marijuana users respectively. Clarke's non-representative New Zealand sample found 46% had 'some' or 'strong' belief in auras (Clarke, 1991 ), while 23% reported personal experience of aura perception (Clarke, 1995). In most of these publications it is not noted if definitions or criteria are specified for aura perception or other phenomena covered in these self­ report surveys, or whether definitions are standardized across countries when comparing surveys. Without such parameters being explicit it is possible that lack of clarity relating to the meaning and translation of such terms as 'clairvoyance' and 'extra-sensory perception' may result in the experience of perceiving auras being subsumed or excluded under these other categories. For example, several of the European surveys noted by Haraldsson (1985) did not have a specific category for reporting belief in or personal experience of aura perception as a separate category, yet aura perception is often understood as a function of clairvoyance of extra-sensory perception in folklore. This illustrates one of the major challenges in drawing conclusions from cross-cultural data on aura perception and other similar experiences, and an issue that needs to be considered regarding the validity and usefulness of such findings. 1.4 Conceptual Frameworks in Aura Research Early Models As might be expected with a topic that has attracted scant academic attention, there has been little development of conceptual frameworks or models to further understanding of reports of aura perception. Even given the lack of any acceptable scientific explanation of the aura as an objective phenomenon, surprisingly few attempts have been made to 8 speculate upon why reports of aura perception have been so widespread across time and place. One of the earliest attempts at a psychological explanation of reports of aura perception suggested this phenomenon may be the result of 'unconscious dramatization', a convenient way in which the unconscious mind presented information about the subject, possibly obtained via extra sensory perception, to the conscious mind (Ellison, 1962). The obvious difficulty with Ellison's explanation is that it rests in part on one reported anomalous experience to account for another. Ellison's contribution is not without merit however, as not only has his original proposal reemerged in more modern guises, but he attempted to progress research by suggesting it's direction. Ellison argued that many aspects of anomalous experience might be resolved with closer study of perceptual processes, and that a "deeper study of the mind at all it's levels is of the greatest importance in psychical research" (1962, p. 364 ). Interestingly this advice has been unheeded until recently, and later models proposing ideas similar to 'unconscious dramatization' make little reference to Ellison's proposal, although it is certainly possible other researchers arrived independently at the same explanation. A decade after Ellison's (1962) publication, Tart (1972) considered some of the conceptual and methodological issues inherent in studying this topic and suggested four ways of conceptualizing the aura. The 'Psychical Aura' is that proposed to exist objectively but consisting of a currently unknown type of energy, and requires extra-sensory ability to detect. The 'Physical Aura' he termed as that made up of scientifically validated types of energy which may be detectable close to the body with current technology, such as thermal energy, electrostatic energy, and electromagnetic radiation. The 'Psychological Aura' he referred to as the mental concept of space around people which did not exist in an objective way, but which he felt was best illustrated in studies of invasion of personal space. Finally Tart proposed the 'Projected Aura' as a phenomenon existing only in the mind of the observer but which is 9 projected upon the observed person and experienced as a perception of an objective thing. Tart described this type of aura as an information display system whereby a range of information, including that received by extrasensory means, is delivered to the observer's consciousness and projected on the observed. In this model the observer is making an error in attributing his or her own information display process to something that exists in the outside world. This concept is clearly equivalent to Ellison's (1962) 'unconscious dramatization', and could be considered as a kind of 'reverse Rorschach' model of aura perception - instead of a physical stimulus (the ink blot) evoking subjective responses, subjective responses to the subject produce the appearance of an apparently physical stimulus (the 'aura'). Tart (1972) suggested the 'Doorway Test' as a way of further investigating some of these proposed concepts of the aura. In this test a target person stands close to the edge of a doorway on half of the trials so the physical body is not detectable while the aura, if it exists in an objective way, would emanate into the doorway space and be perceptible to a sensitive observer. Similarly, when standing further away from the edge of the doorway the aura should not be detectable. Tart attempted such an experiment some years later, using a single subject reputed to have considerable psychic ability. Despite reportedly favorable psychological conditions, the subject was correct on only half of the ten trials in identifying when the target person was standing next to the doorway- a result expected by chance (Tart & Palmer, 1979). Tart concluded these results were not totally incompatible with some kind of psychic component to the aura, and that his subject's reports of aura perception were not a matter of detecting something that was objectively located in the space immediately adjacent to a person's body. He felt these results were explainable by the concept of the 'Projected Aura'. Rosa, Rosa, Sarner and Barrett (1998) used a version of the Doorway Test to investigate perception of the human energy field by Therapeutic Touch practitioners, and found similar results. Therapeutic Touch is a 10 widely used nursing practice in which the practitioner manually manipulates the subjects energy field above the clients body - despite the name, Therapeutic Touch does not involve physical contact with the subject. The researchers' determined that the definitive test of Therapeutic Touch was not a clinical trial of its alleged therapeutic effects, but a test of whether practitioners could actually perceive energy fields. Twenty-one subjects with 1 to 27 years experience of Therapeutic Touch were tested under blinded conditions to determine whether they could correctly identify which of their hands was closest to one of the investigators hands. Before testing, subjects all claimed they could use Therapeutic Touch to significant therapeutic advantage, and described sensory (rather than visual) cues they used to assess and manipulate the energy field , such as 'Yingling, pulling, throbbing, hot, cold, spongy, and tactile as taffy"(Rosa et al. , 1998, pg 1007). In this experimental design subjects rested their hands approximately 25-30cm apart with palms upward, with vision being obscured by an opaque screen and a draped towel. One of the researchers then placed her hand palm down 8-10 centimeters above one of the subject's hands, determined by the flip of a coin, and the subject was given as much time as needed to indicate which hand was nearer the experimenter's hand . Subjects identified the correct hand in only 44% of the total 280 trials, which as with Tart's (1979) results is close to what would be expected for chance. There was no correlation between individual practitioner's scores and length of experience using Therapeutic Touch. The researchers concluded that practitioners inability to detect the energy field in this experiment constituted evidence that the claims of Therapeutic Touch are groundless, and further professional use was unjustified. This study employed an elegant design and is of value in it's replication of previous similar findings, however a derisive undertone is unmistakable, and it makes no contribution to furthering understanding of the widespread reports of aura perception. Tart's ideas and conceptual model were more recently taken up by Icelandic researchers Gissurarson and Gunnarsson (1997). Ten subjects 11 who claimed to see auras at will, including some professional psychics, and a control group of nine subjects claiming no special abilities, were tested using another variation of the Doorway TesL Subjects were asked to determine behind which of four randomly chosen opaque screens one of the researchers was standing, by attempting to detect the researcher's aura extending from the side of the screen. Despite a large number of trials, again results showed the success rate was no better than chance for either group, leading researchers to conclude their study showed no evidence of aura vision. In addition to replicating findings of similar studies, the greater contribution by Gissurarson and Gunnarsson (1997) is to offer a thoughtful update of Tart's (1972) model in an attempt to progress research in this field . They propose a four-model framework similar to Tart's, dropping his concept of the 'Psychological Aura ' and adding 'The Clinical Model ', and elaborating on the 'Proposed Aura ' to create 'The Aura Imagery Model '. An expanded version of this framework will be used to discuss further literature on the aura for several reasons . Apart from the earlier work of Ellison (1962) and Tart (1972) on which it builds, there were no other conceptual frameworks for studying the aura located in the literature. This means it is the most contemporary conceptual model available from which to consider the results and analysis of the current study. This four model framework can also be thought of as presenting various discourses on the aura, and so allows for integration of both academic and non-academic material, which is otherwise difficult to synthesize in a meaningful way. 1.5 The Four Model Framework The Psychical Model The Psychical Model proposes the existence of the aura as an objective reality in the external world, hitherto undetected by existing scientific 12 technology. Claimants' reports are treated as genuine as they are assumed to perceive a real phenomenon to which people are differentially sensitive. The aura generally has a psycho-spiritual nature in this discourse. Because the premises of this model do not fit well with the traditional scientific approach, in that the phenomenon is accepted as having an objective reality without verification meeting scientific standards, publications exemplifying this model are not found in academic literature. However examples abound in the popular press, and the following material has been selected to illustrate this model because it represents either first-hand reports of aura perception from prominent proponents of this model, or relates to a special area, such as the reported experiences of children. Theosophy The Theosophical Society was founded in New York in 1875 by Russian H. P. Blavatsky and American journalist and lawyer H. S. Alcott, and five years later settled it's international headquarters at Madras in India. Theosophy sort to integrate the common principles and beliefs underlying all the major religions with science and philosophy, at a time when Eastern and Western worldviews were diametrically opposed. Drawing heavily on Eastern spiritual concepts such as reincarnation and karma, it has at times been misunderstood as "an occult religion" (Rosa et al, 1998, p. 1006). However, Theosophy is open to anyone regardless of religious background, and encourages members to study comparative religions rather than change their faith (Wood, 1924; Cooper, 1964 ). The Society's cofounder Blavatsky (1950) and a number of prominent members such as Leadbeater (1952; 1977) and Besant (1960; 1992) published comprehensive and consistent accounts of the workings of the human energy field based on their own reported perceptions. Four distinct interpenetrating layers of the aura are referred to in Theosopical works, being the inner-most etheric double or etheric body; the emotional or astral body; the mental body; and the causal or soul body. The etheric body is described as a striated bluish-grey mist extending 13 outwards for less than an inch, with the straight or drooped arrangement of the striations indicating the general health of the physical body. The etheric body is purported to conduct prana or vitality through the body via the nervous system and out through the skin. The astral body is reported as an oval shaped form extending on average one and a half feet from the body, having the appearance of a mist of various colours which change in relation to the emotional and mental state of the subject. These colours are consistent across subjective states of individuals, for example, rose is said to correlate with affection or love; grey with fear; blue with devotion; and scarlet red with anger. The mental body is described as of a similar size and shape to the astral, but more radiant and with clearer colours, particularly variations of yellow light which accompany intellectual activity. Strong thoughts and feelings are said to produce forms and waves in the astral and mental bodies, which radiate out in all directions. The causal or soul body, which in Theosophy is also called the Ego, is said to be the mold on which the mental and emotional bodies are fashioned. In it's developed state it is described as an ovoid of flashing iridescent light of many colours. As can be taken from these descriptions, the aura in totality is conceived of as the spiritual essence of a person, rather than being an artifact of the workings of the physical body. Despite never having had a high profile or membership, it is hard to underestimate the influence of Theosophical thought in informing current treatises on the topic of the human aura from the perspective of the Psychical Model. Arguably no other single group or tradition has contributed so prolifically to the presentation of this construct within the public arena within the last century. The following proponents of the Psychical Model all appear to draw heavily on Theosophical concepts in description and explanation of the aura. Shafica Karagulla The work of neuro-psychiatrist Shafica Karagulla (1914-1986) deserves special mention here, in spite of, or perhaps because of the fact that 14 prior to her study of what she termed 'higher sense perception', her position on such phenomena was firmly in line with the Clinical model. Born in Turkey and educated in Beirut, Karagulla completed her medical residency in Edinburgh, Scotland, developing a special interest in hallucinations and electro-convulsive therapy. She was then invited to work with renown neurologist Wilder Penfield at the Montreal Neurological Institute in Canada, whose investigations at the time involved mapping out the different functions of the cerebral cortex. Based on her research with Penfield, in 1955 Karagulla co-authored an article in the British Medical Journal describing the psychical phenomena produced by electrical stimulation of the brain during craniotomy in subjects with temporal lobe epilepsy (Karagulla & Robertson, 1955). At this time she firmly believed all such phenomena were hallucinations or illusions, and could be explained by neuropathology. The year after this publication, however, she was introduced to the work of Edgar Cayce (1877-1945), an American whose reported psychic abilities she felt could not be adequately explained by the disciplines in which she had studied. Cayce reported a number of paranormal experiences beginning in his youth, and in adulthood while in a hypnotic state would speak on a wide range of subjects, including giving health readings for individuals present and living great distances away (Cayce, 1969; Karp, 1986). While Cayce reported seeing auras routinely in his non-hypnotic state, he did not refer specifically to auras in his hypnotic sessions. His inability to remember consciously the content of these sessions, to which he had no previous exposure or training, aroused Karagulla's curiosity and led her to search for explanations outside of her medical training. For three decades from the mid 1950's until her death in 1986, she sought out people in the United States and beyond who were reputed to show similar abilities to Cayce's, which she termed 'higher sense perception'. This included the perception of auras, healing, remote viewing, dowsing, and psychokinesis. Karagulla was able to work over a number of years with a small group of 'sensitives' whom she felt exhibited particularly well developed and consistent abilities. In 15 accordance with her medical training Karagulla pursued a particular interest in reported perceptions of the human energy field in health and disease. In 1967 she published a book for the popular press collating her investigations into higher sense perception, noting consistent descriptions in reports of aura perception from widely separated sensitives which had convinced her it was necessary to entertain at least the hypothesis that such fields existed (Karagulla, 1967). Her collections of these reported observations suggested three clearly discernible but interpenetrating fields, beginning with the most proximal vital field or etheric body extending one to two inches from the physical body. This field was described as a sparkling web of light with filaments perpend icular to the body contour in a healthy ind ividual. The effects of damage or disease were notes as changes in size, shape and intensity of the aura, which at times was reported as preceding any physical signs or symptoms of disease. The emotional field was described as extending a foot to eighteen inches, appearing as colours which would change rapidly at times, dependent on mood and interaction. The mental body was reported as extending two feet or more beyond the body. A number of Karagulla's informants also reported perceiving major energy vortices or chakras up and down the spine and a greater number of minor vortices elsewhere, through which energy entered and exited these bodies. The major chakras were reported as having a direct action on their corresponding endocrine glands, and via this mechanism on the functioning of the physical body itself. In an attempt to gather and synthesize a range of case studies Karagulla collected extensive observations of the aura and chakras in both healthy and ill subjects in collaboration with one particular sensitive. Karagulla reported this woman was able to identify disorders in a number of patients based on their energy fields, which were then validated by medical records. From these cases she began making tentative hypotheses as to the principles and properties of the aura, and in particular the chakras. Unfortunately she did not complete this work before her sudden death in 1986, however, this material was edited and 16 published several years later (Karagulla & Kunz, 1989). This formulation of the human energy field is clearly very similar to that espoused in Theosophical literature, and the collaborating sensitive and second author of Karagulla's last book was Dora Van Gelder Kunz, a longtime president of the American Theosophical Society, and the co-founder of Therapeutic Touch. Dora van Gelder Kunz and Therapeutic Touch Therapeutic Touch was introduced in the United States in the early 1970's by Dora van Gelder Kunz and Dolores Krieger, the latter a nursing faculty member at New York University. Of the 17 publications located on the aura through the PSYCINFO search, five were either focused on Therapeutic Touch or referred to this practice in relation to the human aura. Arguably no other modality based on the concept of the human energy field has been embraced so closely to mainstream healthcare. Nurses make up the largest occupational group of Therapeutic Touch practitioners, which is practiced in over 80 hospitals in North America. This modality is taught in more than 100 colleges and universities in 75 countries, and is said to be the most recognized technique used by practitioners of holistic nursing (Rosa et al, 1998). It is promoted by many professional nursing organizations, has yielded it's own assessment forms (Wright, 1991) and been applied to specialty areas of practice such as midwifery (Buenting, 1993). Not surprisingly, Therapeutic Touch is not without controversy or it's opponents. The inclusion of the nursing diagnosis 'Energy Field Disturbance' by the North American Nursing Diagnosis Association (Carpenito, 1955), for which Therapeutic Touch is the only treatment, caused a storm of debate within and outside of the profession. James Peterson - Aura Perception in Children Another contribution to the Psychical Model in popular literature is included here as it is one of few studies on children's reported experiences. Educator James Peterson initially became interested in children's anomalous experiences while working as a camp counselor in 17 Pennsylvania, after overhearing an eight and nine year old boy discussing the colours they saw around him while he was meditating. Informal talks with children on a range of experiences developed into a post-graduate research project on the paranormal experiences of children. Peterson found nearly 7% of his subjects under the age of nine years reported psychic experiences on a daily basis. Peterson had a particular interest in reports of aura perception as this was the experience that stimulated his initial interest in this field. He believed aura perception was one of the most common types of anomalous experience for children, evidenced by the ease with which he was able to gather reports of this type for his research. Most of these children reported perceiving auras only intermittently and spontaneously in situations where there appeared to be an intensity of emotion present, for example, when someone was particularly angry or happy. However, a minority of subjects reported this as a volitional experience. Peterson draws heavily on the Theosophical model of the aura in discussing his findings, and anecdotal examples given are congruent with Theosophical treatises on the relationship between physical and emotional state and appearance of the aura. For example, Peterson reports a five year old boy, after observing Peterson smoking a pipe looked intently around his body and suggested he shouldn't smoke as it changed the while light around his body to blue, brown and black. One child reported 'pinky twinkles' all over his divorced father who had just fallen in love, while an eight year old drew a picture of red specks around the head of her teacher that were apparent to her only when the teacher became upset (Peterson, 1987, pp 51-52). Based on his finding that such anomalous experiences are common in children but reduce sharply at seven or eight years, Peterson proposed that such experiences were part of normal developmental progression, and represented a recapitulation of psychological functioning in earlier human development. Barbara Brennan A leading contemporary proponent of the Psychical Model, Barbara Brennan presents something of a quandary for the scientific 18 establishment. Although trained as a physicist and employed for some years as a research scientist for NASA, Brennan also reports clairvoyant experiences in her childhood, which began again when she changed career direction and began working as a therapist. Brennan (1987; 1993) reports observing seven interpenetrating layers of the aura, and seven funnel shaped vortices or chakras positioned vertically through the centre of the body. Beginning with the first or etheric layer closest to the physical body, every odd numbered layer is described as structured with fine scintillating lines of light standing perpendicular to the physical body. Even numbered layers, beginning with the emotional body are described as having the appearance of coloured fluids in constant motion. Descriptions of properties and features of the aura in different mood states and in health and disease, such as shape, size and colour are generally consistent with those described in Theosophical literature. Brennan's work extends on the Theosophical model, however, in her explanation of the relationship between character structure and auric patterns. Developed over many years of therapy practice, her model is based on correlations between her observations of energy fields, and the physical and emotional problems of her clients. Brennan's work is more than just a broad phenomenological account of her observations - similar to Theosophy she proposes a comprehensive psycho-spiritual model that unifies the body and mind and maps a holistic path for healing. Scientific explanations and medical knowledge are blended with intuitional insights and information from spirit 'guides'. Readers are encouraged to consult both allopathic and complementary healers in their search for health, which according to this model is essentially the path of spiritual growth and enlightenment. Having given up her private practice after the publication of her books, Brennan now directs her own healing school in Miami which requires students to acquire basic medical knowledge alongside her model, and encourages graduates to integrate their practice within mainstream healthcare. 19 As can be seen from the above material, the Psychical Model generally rests on first and second-hand reports of aura perception which show remarkable consistency for both general and specific features. Despite such accounts often being dismissed as subjective and therefore of little value, this does not preclude this model from profitable study. The Psychical Model contributes a wealth of phenomenological material which could be reexamined with broader methodological approaches and evaluations of validity, and contribute much to the understanding of reports of aura perception. The Scientific Model This model is based on the natural sciences, and according to Gissurarson and Gunnarsson (1997, p.42) "gives no reason to contemplate, let alone accept the aura hypothesis as no evidence exists that suggests than an aura surrounds people at all times ". The Scientific Model assumes claims at best are the result of optical illusions or unusual meteorological conditions, and at worst are fraudulent. The Scientific Model of these researchers differs from Tart's (1972) 'Physical Aura' in that it does not discuss the aura in relation to various known energies around the body as those described by Tart. These can be considered together however, as they share the premise that reports of aura perception can be explained by the existing laws and principles of the natural sciences rather than requiring spiritual or 'supernatural ' explanations. Other material has also been included in the discussion of this model where researchers have adopted similar premises, even if positing a previously unknown energy type or using new technology. Walter Kilner and Oscar Bagnall A scientific approach to investigating the existence of the aura as an objective phenomenon commenced at the beginning of the twentieth century with the work of Dr Walter Kilner, an English medical doctor who was head of electro-therapy at St Thomas's Hospital in London. Kilner experimented with dicyanin, an organic coal tar dye, hypothesizing that if the aura had an objective, external reality it may be visible if viewed 20 through a suitable substance. His apparatus consisted of a narrow viewing box with a cell of optically ground glass containing dicyanin in an alcohol solution . Subjects stood unclothed against a homogenous backdrop with light in the room controlled by double blinds. From 1908 until the first World War halted supplies of the German produced dye, Kilner examined hundreds of subjects, recording and publishing his findings in a popular press book (Kilner, 1965). Based on his observations, Kilner described the aura as a whole as having the appearance of a faint mist enveloping the body, but separated it into three well defined divisions with a fourth added for convenience. The first layer out from the body he labeled the etheric double, in accordance with Theosophical teachings on the subject. Kilner described the etheric double in healthy subjects as being a dark band of uniform width no more than 11.i inch and following closely the contours of the body. He initially conceived of this as an optical illusion, but on further investigation observed slight changes amongst subjects, and across the same subject in different conditions. Next followed an inner aura, a blue-grey band of 1 Yi to 3 Yi inches thick which appeared finely striated at right angles to the body. The outer aura Kilner described as being more nebulous and inconstant, showing greater variance with ill health and gender, with descriptions of width ranging between approximately 5 and 15 inches. While Kilner also referred to an ultra­ outer layer, most of his observations were confined to the inner and outer auras, the ultra-outer being described as a finer layer seen only infrequently. He also reported frequently observing 'rays' shooting out from various body surfaces while observing subjects. These would stop and start suddenly, in some subjects appearing to be located at sites of pathophysiology, such as a fibre-adenoid tumor of the breast. In a small number of subjects these rays appeared to be initiated by intent and concentration, with reports of rays emanating from the nose, nipple and fingers on his direction. Changes in colour and size of the aura were also consistently reported following the application to the subject's body of static electricity, and chemical vapours such as iodine and bromide. 21 Kilner reported the properties of auras as being dynamic size and shape, degree of brightness, and texture - the latter property referring to the apparent fineness or coarseness of the composing layers. Based on hundreds of observations Kilner reported no two auras being exactly alike, with variance being due to age, gender, temperament and state of health of the subject. He documented a range of changes in both the inner and outer layers he believed correlated with the health of the subject, some being general changes such as reduction in size or brightness, and other changes correlating to specific conditions. For example, Kilner reported changes in symmetry of the aura occurring in epilepsy and hemiplegia which appeared to remain constant, in one case 27 years after the last seizure, whereas the aura appeared to return to normal in more transient illnesses. As an example of the latter, Kilner described a subject with herpes zoster infection who had vesicles on the abdomen, as having an aura with a 'honeycombed' pattern with vacuoles adjacent to the rash, producing a spongy or cellular appearance. Kilner also reported consistent changes in the auras in females occurring over several years during the onset of puberty; at the onset of menses; and within a few weeks of pregnancy. He also noted the absence of an aura in a small number of corpses he had examined with his equipment, within several hours of death . Kilner proposed that the aura arose from the physiological functions of the body, and consisted of ultra-violet light frequencies beyond the detection of the normal functioning of the eye. He believed that viewing through the dicyanin screens produced changes in the ability of the eye to detect these higher frequency, shorter wavelength rays in the ultra­ violet spectrum. Kilner cited the consistent effects of the correction of longsightedness on those who used the dicyanic screens as supporting evidence of such effects. Despite Kilner's explicit disclaimer of any clairvoyant or occult preoccupation; reports of visitors corroborating his findings at the time of examination; and his assertion that replication was possible for anyone 22 taking sufficient interest in the subject, Kilner's work met with little acceptance amongst the medical fraternity. Initial reviews were distinctly skeptical, and many people failed to see the human aura through Kilner's devices, although how keenly individuals replicated his original observation conditions is impossible to speculate upon. Later reviews reportedly met with more sympathetic reviews, including the endorse­ ments of his findings by many reputable doctors (Kilner, 1965). Kilner did not live to enjoy this support however, dying in 1920 at the age of 73, having achieved little impact on the acceptance of the aura within professional medicine. The validity of Kilner's work has also been refuted both on the basis that he was himself a gifted clairvoyant, and that his findings were the effects of optical illusions, although these would appear to be mutually exclusive arguments. 'Kilner goggles' are still obtainable, which consist of a pair of lenses coated in the dicyanin dye. Tart (1972) credits Ellison (1962) with measuring the optical transmission characteristics of these goggles to show that transmission was very good in the far red and the far violet ends of the spectrum, but cut off almost all light in the middle of the visible spectrum. A closer reading of Ellison's work reveals this testing was reportedly carried out by 'a colleague', and details of the testing procedures are not discussed (1962, p. 361 ). Ellison does describe, however, how images correctly focused on the retina for one of these bands at either end of the light spectrum will be slightly out of focus for the band at the other, due to the eye having a certain amount of chromatic aberration. The out-of-focus image will then appear as a blurred outline superimposed on the other image, hence producing Kilners 'aura', according to Ellison. Despite sounding imminently suitable for further empirical study, there was no mention found in the literature of any investigations using Kilner's goggles. Kilner's work was not completely without impact, and in the 1930's another English scientist attempted to replicate his work (Bagnall, 1975). Although altering Kilner's original dye solutions slightly, Bagnall reported 23 similar findings both in terms of the overall appearance of the auric layers, and in changes observed in specific conditions such as pregnancy or after surgery. Similarly to Kilner, Bagnall refuted occult or spiritual explanations for the aura, and believed it should be a matter of scientific interest and subject to science's methods, as well as having potential value in the diagnosis of disease. Other arguments put forward to explain the aura as an optical illusion preceded that of Ellison (1962), although explanations for how exactly the illusion was produced differed. Fraser-Harris (1932) explained Kilner's etheric double as an optical illusion produced by minute oscillations of both the observer's retina and the subject. The erroneous perception of an aura, caused by the image of the subject constantly moving on the observer's retina is offered as explanation for the absence of an aura in a corpse (which doesn't move). Similarly, this could explain the wider etheric double reported distally by Kilner, as slight movements of the body are more detectable toward the peripheries. Kilner's 'inner aura' is also accounted for by Fraser-Harris as afterimage and 'periodic retinal darkening', leading the author to conclude that this phenomenon is explained by "the principle of spatial or of temporal retino-cerebral induction" (1932, p. 184 ). Over five decades later the explanation of auras as optical illusions continued , with Dale, Anderson and Wyman (1978) claiming to produce aura perception under laboratory conditions. These researchers presented the outline of a human head and shoulders sandwiched between five coloured slides to two randomly assigned groups of ten college students, one group receiving a focused image and the other a purposely blurred image. Subjects were asked if they saw an 'aura' and if they did, what hue it was. In all cased but for the red slide, those viewing the blurry image saw the complementary hue more times than the group presented with the focused image. The researchers argue that blurring the image increased the 'aura phenomenon' as predicted, 24 and therefore auras can be explained as a combination of border contrast and after-image effects. A completely different explanation for some incidents of aura perception was put forward by Bryant and Jarmie (1974 ), who describe a phenomenon called 'the glory' in which a person's head is perceived to be surrounded by a series of coloured halos. This has been reported to occur outdoors and at close range in the presence of certain weather conditions, when a shadow is projected on a cloud of uniform water droplets. A similarly phenomenon has been frequently reported around the shadow of an airplane falling on a cloud . Kirlian Photography No discussion of the history of investigation into the aura would be complete without mention of Kirlian photography. Devised by Russian scientists Semyon and Valentina Kirlian at Kazakh State University in the 1930's, Kirlian photographs show colourful fringes of light around the borders of living objects, but which are absent for non-living objects. This method requires that the object to be photographed be placed into a high voltage electrical circuit so that it acts like an electrode as electricity flows through the circuit. Arguably the most well known example of the Kirlians' work is 'the phantom leaf effect' - Kirlian photographs of an intact leaf alongside the same leaf cut in half, but with the latter showing a pattern of light remaining on the film where the leaf has been cut. Other comparisons made by Kirlian photography show differences in 'fields' (coronas of light on the photograph) around the edges of subjects on whole and junk food diets; around the hands of healthy and diseased subjects; and around raw and whole foods versus cooked and processed food . When Kirlian photography was first brought to public attention in the 1970's it was hailed as long awaited evidence of the objective existence of subtle energy fields (Ostrander & Schroeder, 1970). Initial enthusiasm waned, however, as results were variously attributes to movement 25 artifact and moisture content of objects (Dale et al., 1978). In a recent popular press book dedicated to debunking 'pseudoscience', Hines (2003) elaborates on the moisture content explanation for Kirlian photographs, and notes that a number of other variables have also been shown to affect the nature of the image, such as type of film and electrode used. However, no explanation is offered for the 'phantom leaf effect' . Harry Oldfield The work of English biologist Harry Oldfield represents another attempt to investigate the aura using the methods and principles of the natural sciences. Oldfield was an early pioneer in the use of Kirlian photography, and was also interested in the potential of crystals to generate electromagnetic fields , which could be used therapeutically. Together with Cambridge psychologist Roger Coghill, Oldfield published a book for the popular press detailing the history of scientific endeavors in this direction, as well as his own work in the use of these methods to diagnose and treat disease (Oldfield & Coghill, 1988). Based on the many criticisms of the Kirlian technique he went on to invent a three dimensional Kirlian 'gun' which could produce a video image of the subject surrounded by coloured light, which he called 'Polycontrast Interference Photography', or 'P.l.P.' (Soloman & Soloman, 1998). This technology was based on Oldfield's idea that if an energy field did exist around humans it would interfere with the light in the environment reflecting off the subject, which could be measured. P.l.P. measures the light in the environment bouncing off the subject, and a computer programme colour-codes this information and creates the patterns on the monitor. To date, Oldfield reports being able to correlate a variety of medical conditions with specific patterns on P.l.P. scans, such as tumors, infections, and muscular-skeletal complaints. Unusual patterns on PIP have also been reported around subjects preparing to do 'laying on of hands' healing. 26 Although Oldfield appears to draw on aspects of the Psychical Model in constructing hypotheses, his work is still best located within the Scientific Model. Despite challenging previous conclusions of this model, his work attempts to quantify the human energy field based on the methods and principles of the natural sciences. To date no investigations of Oldfield 's theories or devices have been published . As an essentially independent researcher working without the support of institutions he has been advised that the cost of independent controlled trials of his work would be prohibitive, although he remains enthusiastic about this possibility (personal communication, 2002). The material above represents examples of a natural sciences approach to the investigation of the aura, but is not exhaustive. A variety of other studies and findings have been put forward in support of the objective existence of the aura, some by respected mainstream scientists and academics (e.g., Oschman, 2000). The scientific background to many of the theories and technologies presented above are much more complex than can be described here, and evaluation of this work is beyond the scope of the present study. How well some of these explanations account for aura perception depends on how the aura is defined. Some optical illusions can undoubtedly produce 'colours around people', however, how closely laboratory produced optical illusions match with phenomenological accounts of aura perception such as reported from the Psychical Model is arguable. The Clinical Model This model accounts for the aura as the result of various organic pathologies - an epiphenomenon of errant biophysicochemical factors in the nervous system. Reports of the aura are assumed to be visual hallucinations caused by some form of mental illness; arising from the neuropathology causing epilepsy; or the result of some kind of disorder of the eye. However, as noted by Gissurarson and Gunnarsson (1997), signs and symptoms of these disorders do not map well to reported perception of auras, nor do aura reporters appear to suffer from such 27 disorders. No literature could be located that exemplified this model, as to date no medical disorder or disorders can account for the widespread reporting of auras. In it's purest form therefore, this model would appear to be rest on explanations that do not stand up to scrutiny and provides little promise for furthering study in this area. Given the lack of supporting evidence it seems likely this model is based on a belief that such a phenomenon cannot occur, rather than an careful consideration of reports of aura perception and existing medical knowledge. However, within the last decade a small number of studies have highlighted various aspects of personality and correlates of pathology found in those reporting aura perception and other anomalous experiences. These studies can be conceived of as sharing the formulation of the Clinical Model and therefore appear to be appropriately considered here. Alvarado & Zingrone (1994) set out to investigate the relationship between claims of aura perception, vivid visual imagery and fantasy­ proneness. A variety of self-report questionnaires were filled out by 19 self-selected aura reporters and 19 control subjects matched by age and sex. Instruments included the authors own Questionnaire on Auras and Other Experiences (QAOE); the Vividness of Visual Imagery Questionnaire (VVIQ) (Marks, 1989); and the Inventory of Childhood Memories and Imaginings Children's Form (ICMIC) (Myers, 1983). Results confirmed the two main hypotheses that aura vision is related to higher levels of reporting of vividness of visual imagery and of imaginative-fantasy experiences. In addition the aura reporters had a significantly higher frequency of claims of other anomalous experiences. These findings are in conceptual agreement with other studies that have found that measures of fantasy-proneness seem to be successful predictors of psychic phenomena other than aura vision (Myers, Austrin, Grisso & Nickeson, 1983; Wilson & Barber, 1983). 28 A number of other studies focusing on a variety of anomalous experiences rather than aura perceptions specifically, also appear to fit well within this model. Ross & Joshi (1992) highlight that the only data on paranormal experiences found in contemporary psychiatric literature refers to the association of extrasensory/paranormal experiences to a history of childhood trauma and dissociative symptom clusters. To determine if the relationship between childhood trauma, paranormal experiences, and other dissociative symptom clusters held in the general population, these researchers administered the Dissociative Disorders Interview Schedule (ODIS) (Ross, Heber, Norton, Anderson, Anderson & Sarchet, 1989) to a randomly selected sample of 502 adults in a Midwestern Canadian city. The ODIS inquires in detail about childhood physical and sexual abuse as well as extrasensory experience, and makes a range of Diagnostic and Statistical Manual (DSM IV) diagnoses. Referring to a 1991 poll (Gallup & Newport, 1991 ), Ross and Joshi (1992) noted that extrasensory or paranormal experiences were common in the general population, and the rates of such experiences in their sample were either the same or lower than for the general population, with 65% of subjects reporting having at least one of these experiences, and nearly 10% reported having four or more. Results showed subjects reporting childhood abuse of any kind had an average of 2.3 paranormal experiences per person, compared with an average of 1.2 for the non-abused group. The researchers concluded that available evidence suggested paranormal experiences are dissociative in nature and linked to childhood trauma and other dissociative symptom clusters, however, they also asserted that paranormal experiences are not necessarily pathological in nature, and indeed are often deliberately cultivated by psychologically healthy and high functioning individuals. They proposed a model in which paranormal experiences are an expression of normal dissociative capacity. McClenon (1994) also suggests that dissociative faculties and related traits regulate the incidence of anomalous experiences, opposing previously proposed hypotheses suggesting that religiosity and scientific 29 training affect the reporting of these episodes. This latter group of hypotheses, labeled 'cultural source theory', conceive accounts of anomalous events as wholly the product of the reporters culture, resulting from and alleviating existential anxiety or fulfilling other unmet needs. The ubiquitous nature of such accounts is seen as reflecting social disorders, tension and flaws in the scientific education training. Mcclenon tested hypotheses deriving from cultural source theory by polling samples of Caucasian-American, African-American, Chinese and Japanese college students regarding a range of anomalous experiences. While the incidence of reported experiences varied across the groups, religious preference, self-reported religiosity and scientific training did not predict frequency of, or belief in extra-sensory experiences. McClenon proposed that the scattered and meager relationships found between religiosity and anomalous reports may be better accounted for by a variety of psychological variables correlated with dissociation, including hypnotic suggestibility, absorption and fantasy proneness. Drawing on a growing number of research findings linking childhood trauma, dissociative experiences and anomalous experiences, McClenon proposes a model whereby the capacity for anomalous experience is a trait influenced by both genetic and cultural variables affiliated with naturally occurring psychological capacities. Heber, Fleisher, Ross and Stanwick (1989) further explored the relationship between reports of paranormal experience and dissociation, comparing 12 community based alternative healers with a control group of 19 psychiatry residents on the Dissociative Experiences Scale (DES) (Bernstein & Putnam, 1986) and the Dissociative Disorders Interview Schedule (ODIS) (Ross et al, 1989). While neither group showed evidence of extensive psychopathology, the alternative healer group reported more Schneiderian symptoms (which include audible thoughts and voices; thought withdrawal and broadcasting; and somatic passivity experiences); extrasensory experiences; and secondary features of Multiple Personality Disorder (now known as Dissociative Identity Disorder). In accordance with the findings of the previously noted 30 studies, these authors note that these experiences did not seem indicative of psychopathology, and in some individuals are even valued and sought after. They conclude that dissociative experiences are not necessarily indicators of psychiatric disorder in non-clinical groups. Persinger & Valliant (1985) found correlations between the number of paranormal experiences and the number of temporal lobe signs reported by a sample of 99 university students. They concluded these results supported the hypothesis that mystical or paranormal experiences are associated with transient electrical foci within the temporal lobe of the brain, but that the repeated occurrence of these experiences within normal individuals may be embedded within a more complex symptomatology of temporal lobe signs. Neppe (1984) also argued that the logical anatomical correlate for anomalous experience is the temporal lobe, and that there is evidence that a background trait of anomalous temporal lobe functioning may predispose to the occurrence of anomalous experiences. However, Neppe argued accounts of paranormal experiences suggest a different quality to those of the temporal lobe epileptic, and strengthen the possibility that the former experiences do not necessarily suggest abnormal temporal lobe firing . These studies can be seen collectively as constituting a 'diluted' version of the Clinical Model, in that they all are cautious about proposing a direct and simple relationship between anomalous experience and pathology, or concluding subjects reporting these experiences have mental or neurological illnesses. However, they share with the more simplistic but unsupported explanations a formulation of aura perception as being fundamentally related to internal processes rather than being stimulated by an external reality. In attempting to use existing understandings of personality and neuropathology or psychopathology to suggest individual differences that may distinguish reporters of auras and other anomalous experiences from non-reporters, these studies 31 offer promise for future understanding of aura perception. However, this model also raises a number of important cultural issues related to what are considered desirable or undesirable features of personality; what constitutes psychopathology; and who makes these judgements. The Aura Imagery Model This model is proposed by Gissurarson & Gunnarsson (1997) as a guide for future aura research as they suggest it may best account for the negative results produced by the Doorway Test and it's variations noted previously. The Aura Imagery Model is an elaboration of Ellison's (1962) concept of the aura as an 'unconscious dramatization' and Tart's (1972) concept of the 'Projected Aura', in which the aura has no objective existence apart from within the mind and brain of the observer. These researchers theorize that on a phenomenological continuum, an aura image may range from a feeling to a real perception. At one end of this continuum aura perception is an association with colour with what a person intuits about others - what they feel , think and experience of other people. At the other end of the continuum this information about the subject may create a real perception, albeit one which is generated by internal neurological processes rather than being externally stimulated by an objectively present aura. In this way aura imagery produces a wholistic experience of the target person expressed in colours - a convenient way in which a variety of information is unconsciously processed and presented to the conscious mind. The authors suggest that this may explain why their experimental subjects were perplexed and frustrated by a lack of positive results, and why they agreed to take part in the experiment at all. The participants genuinely believed and expected to detect an external aura, however, without full experience of the target person they were unable to collect the information that would be required to produce the projected aura image. Gissurarson and Gunnarsson (1997) concur with Ellison (1932) and Tart (1972;1979) in maintaining that the possibility of extra-sensory perception should not be excluded, as additional information may alter or form the experience of the aura perceiver. The authors add to previous similar explanations by 32 suggesting that a variety of information received about others may become consciously connected with colours through learning by association, or by the more complex and involuntary neurological processes involved in synesthesia. Certainly one does not have to look hard to find examples of such learning - in the process of acculturation and language acquisition there are innumerable opportunities for learning such associations. Colour is used everywhere as a symbol - red traffic lights signify the danger of not stopping and green the safety to move forward; red tap tops signify hot and blue or green cold. Social rituals have associated colours such as wearing black for funerals and white for wedding dresses, although these are obviously not universal and vary across cultures. More specific examples of associations between colour and emotional states are commonly found in language - people are described as 'seeing red' when angry, or viewing the world 'through rose coloured glasses' when in love. Envy is often associated with the colour green, as in 'the green eyed monster' or being 'green with envy', and depression is often described as a grey, blue or black mood (interestingly, these associations are all in accord with Theosophical writings on the correlations between subjective states and aura colour). The proposal that synesthesia may play a part in aura perception in the Aura Imagery model requires some elaboration, as this term has been used in both general and specific ways. This term comes from the Greek syn, meaning together, and eisthesis, meaning perception, and has been used to refer to both the tendency for perceptions in one modality to suggest those of another, and to an involuntary physical experience in which one sensory modality reliably causes a consistent perception in one or more different senses. The former can be conceived of as including and extending the cross-modal associations noted above as being learned, whereas the latter or 'true' synesthesia has distinct diagnostic features and can be found in medical literature descriptions going back three centuries. 'Coloured hearing' is the most 33 commonly reported variety of true synesthesia, in which speech and music are not only heard but are experienced with a visual image of coloured shapes and movement. True synesthesia re-emerged as a noteworthy subject in the medical literature in the 1980's due primarily to the work of American neurologist Richard Cytowic (1989; 1993), whose study of a group of synesthetes led to the development of the current diagnostic criteria. Cytowic concluded synesthesia is involuntary but elicited; perceptions are projected into the personal space of the synesthete rather than being experienced 'in the mind's eye'; perceptions are stable over a lifetime; and the synesthetic experience is emotional and memorable. Furthermore, Cytowic proposed that synesthesia is familial , and is more common in non-right handers and in women with gender ratios ranging from 3:1 to 8:1. Synesthetes tend to have superior memory while math and spatial navigation suffers. Synesthesia also appears to depend only on the left-brain hemisphere, and is accompanied by large metabolic shifts away from the neocortex that result in relatively enhanced limbic expression. Synesthesia is a rare experience, with Cytowic (1997) suggesting his own finding of 1 in 25,000 is possibly too low. Cytowic suggests synesthesia is a normal brain process despite being statistically rare, and considers it a premature display to consciousness of normally occurring neurological processes. His use of 'premature' in this context relates to the stages in the perceptual process rather than the development of the individual or species. Cytowic proposes we are all synesthetes but not aware of this, as cross modal associations for most of us occur at unconscious intermediate stages in the perceptual process but are not delivered to the final stage of this process as the finished product of our perception. Synesthesia has been mentioned fleetingly in relation to aura perception previously, but had not been built into any comprehensive model prior to Gissurarson and Gunnarsson (1997). Kenneth (1932) argued that subliminal olfactory stimuli emanated from human and other bodies 34 which could be broadcast over a considerable distance, and which varied according to general metabolism, nutrition, and emotional or affective state. Both underlying neural processes and cross-modal learning appear to be proposed by Kenneth to result in colours being perceived around the subject. This explanation is unique in it's suggestion of both the existence of an objective aura (chemical substances giving olfactory stimulus) and a projected aura (learned and true smell-colour synesthesia). However, Kenneth draws in part on insect behaviour to substantiate his claim, and does not elaborate on how humans could discriminate between subliminal metabolic, nutritional or affective changes in his proposed chemical aura. No comment or discussion on this theory was found in the literature, and Gissurarson & Gunnarsson (1997) do not refer specifically to smell-colour synesthesia in their model. Peterson also refers briefly to synesthesia in his discussion of aura perception in children. He notes earlier psychologists have proposed this condition as a developmental stage in childhood, as well as an explanation for the ''frequent hallucinations that some children experience" (Peterson, 1987, p. 36). However, Peterson disposes with this argument by suggesting the opposite is true - that the entire concept of synesthesia is likely an elaborate and fanciful way for psychologists to claim organic basis for a condition that actually involves childhood clairvoyance. Such polarized explanations for aura perception are a good example of how dualism may have inhibited progress in conceptualizing on this topic. It is interesting to note that synesthetes have reported auras around objects and people, and some have noted that correlations between colours have moods. In Cytowic's (1989) study of 42 synesthetes, one subject 'BB' describes the auras he perceives as colours bordering objects and people which may parallel a boundary, as coming in 'soft splotches' lacking orientation, or appearing as a colour wash which at times obscures the object or subject. These experiences are accompanied by physical sensations of numbness and flushing, and 35 feelings of exhilaration, fear or happiness. The stimulus for these experiences is perceived as coming from the subject. BB's description of one particular incident of perceiving an aura is worth noting, both for his description of what was perceived, and other subjective contextual aspects of the experience (Cytowic, 1989, p. 50): "There was a very strong feeling and she was surrounded by a dark blue-green aura ... I don't know what the emotional feeling was due to because I had only met her twice. But there it was. I think there was some sort of bond or some­ thing. I'm not sure which comes first, sometimes I think I see the colour and react emotionally; others it may be reversed - I get an emotion and then see this colour. I'm not sure. And I don't know what makes it happen." Furthermore, in addition to BB and the subject who reported that colours have moods, Cytowic notes that in his study sample a further seven subjects or 17% reported clairvoyance and other paranormal experiences, including precognitive dreams, psychokinesis, empathic healing experiences, and a kind of emotional telepathy (Cytowic, 1989, p. 236): " ... {I] am particularly sensitive to mood vibrations from others. I can walk into a room and sense almost instantly what each person is feeling about himself or whether there is tension, hostility, 'openness', pretense, etc. " Despite being reminded of descriptions of ictal (seizure) phenomena, and in particular those associated with temporal lobe epilepsy, Cytowic openly acknowledges he does not know what to make of such reports. He asserts however, that these descriptions are quite different from "the comments of oddballs", who presumably are non-synesthetes reporting anomalous experiences (Cytowic, 1989, p. 235). Interestingly, some individuals reporting aura perception have also reported that sound will result in a visual perception of colour and form (Besant & Leadbeater, 1992). This appears to be a somewhat different experience to 'coloured hearing' however, as the example given in this latter reference describes shapes and colours emanating directly from the sound source (in this case a church organ) and reaching quite some distance into the air. These 'musical auras' are noted to be complex and dynamic, as well as being reliable in that the same piece of music accurately played will build the same form, which will appear the same to 36 different individuals with clairvoyant abilities on different occasions. In contrast to these descriptions, reports of 'coloured hearing' in synesthesia note that the shapes and colour are perceived in the personal space of the perceiver, never at a distance. For example, Cytowic (1995) notes a subject who on hearing music, sees falling gold balls, shooting lines, and metallic waves like oscilloscope tracings that float on a 'screen' six inches from her nose. Furthermore, synesthetic perceptions are generally described as idiosyncratic - the same stimulus will evoke different perceptions in different synesthetes. The addition of synesthesia in Gissurarson and Gunnarssons' (1997) model is thought provoking on a number of levels, whether as a explanation for aura perception in itself (i.e., aura perception is a specific type of synesthesia) or as a model for a similar explanation (i .e., aura perception is not synesthesia, but a similar neurological model or process may be implicated). It reintroduces the possibility of a neurological substrate for anomalous experience - that aura perception may be as much 'in the brain' as 'in the mind'. Contextual aspects of synesthetic experiences may also have parallels for that of aura perception, in that it is an unshared sensory experience which subjects are cautious about disclosing for fear of stigma, it has emotional­ experiential correlates, and is a difficult experience to express in language. This model is likely to be attractive to many in it's complexity and eclecticism, however, the inclusion of ESP as a component of this model is likely to make it as unacceptable to mainstream psychologists as the Psychical Model. While proposing some new and thought provoking material, the Aura Imagery model is concerned with the 'big' questions of aura perception, and does not offer specific explanations for the various features which have been consistently reported of auras. The only attempt in this direction, namely the suggestion that "colours and shapes of auras may well be the form in which the ESP material can be dramatized for the conscious mind" (Gissurarson & Gunnarsson, 1997, 37 p. 46), is a somewhat vague and convenient explanation for these features, and has a decidedly psycho-analytic flavour. Gissurarson and Gunnarsson's (1997) conceptual framework, with it's suggestion of the Aura Imagery model as the most promising for future research, provides the most recent theorizing in aura research. However, it is interesting to note the continuation of Ellison's concept of 'unconscious dramatization' in the Aura Imagery model, and his admonition 35 years earlier (Ellison, 1962, p. 364 ): "It may be that the clues to many of the mystifying things of interest to psychical researchers are to be found in perception. Most of our problems might be resolved if we thoroughly understood perception of all kinds, both normal and psychic. It is well worth while to look further into perception, particularly psychic perception." 1.6 Aims and Objectives of the Current Study The construct of the human energy field or aura is an ancient one, and reports of belief and experience of auras continue to be widespread in the present day. Despite increasing public interest and popular press publications, psychology has had little to say about this subject. What little academic literature does exist has tended to focus on establishing the extent of belief and reported rates of experience, often as part of wider studies looking at a variety of anomalous experiences. This provides a useful starting point but does little to explicate the phenomenon, and according to Alvarado (1996, p. 62) "practically no systematic work has been carried out to map the features of this phenomenon". This aim of the present study is to address the scarcity of psychological literature on aura perception from a phenomenological perspective. Interpretive phenomenological analysis was employed as a methodological approach in order to address three further objectives of the study. These were to (i) to seek consistencies and contrasts in reports of aura perception by focusing in depth on a small number of 38 experients reports; (ii) to elaborate on the construct of the aura by considering the contextual determinants embedded in such reports; and (iii) to appraise potential implications of these findings in light of previous research and conceptualizing on the aura within psychology. As the methodology selected for the present study attempts to set aside suppositions and avoid presumptions as much as possible, there were no expectations held or hypotheses proposed for findings related to either reports of the phenomenon itself, the contextual determinants, or any possible arising implications. 39 2. METHOD 2.1 Methodological Rationale As noted above, despite there being a number of models and theories put forward to explain reports of aura perception there appears to be a lack of studies which systematically map features of accounts, or consider these alongside proposed explanations. In particular, no descriptive or thematic studies could be found in the literature which might explicate the parameters of claimants' accounts, or chart the textural aspects of their experiences. A number of research designs were considered in order to find one which would fit most appropriately with the aims and purposes of this study and fill this gap in the literature. A qualitative methodology suggested itself as most appropriate to the aims and objectives of the study for the following reasons. Rather than attempting to find or predict causal relationships among objective, quantifiable variables, the research questions fundamentally address personal experience and meaning making, for which qualitative methodologies are ideally suited (Willig, 2001 ). Qualitative analysis is also suggested as being particularly appropriate if the aim is to capture complexity or process, and when an issue is controversial or personal (Smith, Harre & Van Langenhove, 1995). Finally, topics which are little understood and investigated, such as is the case in the present study, are well suited for qualitative analysis, which may generate theory and suggest the most profitable theoretical and methodological direction for further studies. Of a number of qualitative methods in use in psychology research, Interpretative Phenomenological Analysis (1.P.A.) was selected as the most suitable for both the study topic and it's aims and objectives. l.P.A. was developed by English psychologist Jonathan Smith in the 1990's, who characterized this method as "an attempt to unravel the meanings 40 contained in ... accounts through a process of interpretative engagement with the texts and transcripts" (Smith, 1997, p. 189). LP.A. has been applied widely to topics within health psychology, such as palliative care (Jarret, Payne, Turner & Hiller, 1999); genetic abnormality (Baillie, Smith, Hewison & Mason, 2000; Chapman & Smith , 2002) and sexuality (Coyle & Rafalin, 2000; Flowers, Duncan & Frankis, 2000; Duncan, Hart, Secular & Bigrigg, 2001 ). The growing popularity of l.P.A . has seen it's application extend to clinical and social psychology, particularly in the United Kingdom (e.g., Jarman, Smith & Walsh, 1997; Knudson & Coyle, 2002; Larkin & Griffiths, 2002). Despite LP.A. being a relatively new qualitative method in psychology, it should be remembered that similar interpretative phenomenological approaches have a long history in medical sociology (e.g., Glaser & Strauss, 1967; Goffman, 1968). Despite being a recent approach developed within and specifically for psychology, l.P.A. has theoretical roots in the branch of philosophic thought know as phenomenology, and draws also on the perspective of social interactionism. Phenomenology developed from the ideas of German philosopher Husserl in the early twentieth century, and is concerned with phenomena that appear in our consciousness as we engage with the world around us. It aims to 'return to things themselves' as they appear to perceivers within particular contexts and at particular times, rather than attempting to formulate general laws or abstract statements about the nature of the world. Phenomenology's methodological implications require suspension of assumptions and presuppositions and a description of the totality of a phenomenon together with it's associated components, in order to arrive at an understanding of the essence of a phenomenon. In modern phenomenological psychological research, the research participant's account becomes the phenomenon with which the research engages. While few would now claim it is possible to suspend all presuppositions and judgments in any endeavor, there remains an effort to set aside customary ways of knowing while attempting to enter the experience of another. Phenomenological psychology is also more concerned with 41 diversity and variability in human experience than with Husserl's identification of essences (Spinelli, 1989). Symbolic interactionism emerged in the USA in the 1930's as an explicit rejection of the positivist paradigm beginning to take hold in the social sciences. While being influenced by phenomenalism, symbolic­ interactionalism argues that the meanings individuals ascribe to events should be of central concern to the social scientist. However, it also considers that those meanings are only obtained through a process of interpretation, and that it is only through social interaction that meanings occur and are made sense of. This perspective has only recently begun influencing the field of psychology, and is an integral part of discursive approaches (Denzin, 1995). l.P.A. weaves together both these theoretical strands by aiming to capture the quality and texture of individual experience. It holds with a realist approach to knowledge production in that it starts with an assumption that peoples' accounts say something about their private thoughts and feeling, and these are implicated in their experiences. It recognizes that these thoughts and feelings mediate experience of external 'objective' conditions, meaning the world can be experienced in radically different ways (Willig, 2001 ). Indeed l.P.A. does not make any claims about the external world, or seek to determine whether participants' accounts may be 'true' or 'false' in terms of their correspondence to an 'objective' reality, and in this way subscribes to a relativist ontology. l.P.A. is also reflexive in so far as it acknowledges it's dependence upon the researcher's own standpoint, as well as the nature of the interaction between researcher and participant. These theoretical positions make l.P.A. particularly suitable to the aims and objectives of the current research, which are explicitly not to argue for or against the proof or truth of the aura as an objective reality. l.P.A. appears to provide the most suitable method with which to consider in depth a small number of detailed accounts of aura perception, in order to 42 consider phenomenological findings against existing theories and models. Using this methodology accounts of aura perception constitute the phenomenon in question, rather than the aura itself (as is the case in the Psychical Model). Given l.P.A. is a relatively novel method in psychology it is useful to position it by reference to a more familiar qualitative approach. l.P.A. is noted by Jonathan Smith and others to share much in common with Grounded Theory (Smith, Flowers & Osborn, 1997; Will ig, 2001 ). Both proceed by systematically working through a text in order to identify themes and categories that are progressively integrated until higher­ order units ('core categories' in Grounded Theory; 'master-themes' in LP.A.) are established that capture the essence or nature of the phenomena under investigation . Both start with individual cases which are then integrated to obtain a composite picture that tells us more about the cognitive map that represents a person's or a group's view of the world . However, while Grounded Theory aims to identify and explicate contextualised social processes which account for phenomenon in order to yield theory, l.P.A. was designed to gain insight into the nature or essence of phenomena itself by gaining insight into individual participants' psychological worlds, and so is specifically a psychological research method. 2.2 Steps in Interpretative Phenomenological Analysis 2.2.1 Development of a Semi-Structured Interview Schedule Once the aims and objectives of the study had been decided and the choice of a methodology made, a semi-structured interview schedule was designed (Appendix A). In accordance with guidelines on semi­ structured interviewing (e.g., Smith et al, 1995; Willig 2001 ), the schedule is used to guide the interview rather than to dictate direction and content. To this end questions were designed to invite participants 43 to discuss areas suggested by the researcher, while allowing freedom to probe interesting issues that arise and follow the participants' interests or concerns. While the same areas of questioning are therefore common to each interview, their order and the degree of detail or departure from the question may vary across interviews as this process proceeds. Schedule questions were arranged in an order that was anticipated would follow the natural progression of the interview, beginning with the nature of what was perceived, followed by the contextual aspects of the experience and concluding with meanings made of experiences. Opportunity for the participants to comment on any other aspect not already discussed was also provided in the schedule. Questions were phrased to be open, neutral, and to use participants' own language, with further prompts being added to encourage participants to elaborate. The initial version of the interview schedule was revised several times due to certain terms and phrases potentially precluding some categories of response. For example, the initial title of the study and wording in the interview schedule referred to 'seeing' the aura, but this was replaced by 'perceiving'. It was felt the former term might frame perceptual experiences in an exclusively visual mode, and exclude accounts that were experienced in other ways. Another issue arising was whether to use the terms 'aura' or 'energy field ' in the opening questions. There was concern this might infer to the participants that the researcher held certain epistemological and ontological assumptions about the experience (i.e., that by using a noun this reifies the experience, suggesting it had an objective reality and that it can be 'known' about in certain ways), and that only responses which concurred with these assumption were desirable. An alternative was to draw on features of auras widely reported in popular descriptions and ask if the participant had perceived light, colours, energy or anything else around the body. The latter was potentially equally problematic, as it essentially implies the same thing. After some consideration it was decided that the study required accounts by participants who had already labeled their experiences as incidents of perceiving what was possibly an aura or 44 energy field, and both questioning approaches were therefore combined. It was hoped this left the question open enough to be answered in a variety of ways, with the option of offering a range of explanations or attributions for experiences. These initial challenges in designing a schedule increased mindfulness about the discursive aspects of language and issues of epistemological reflexivity, and ongoing efforts were made to remain conscious of these reflections throughout the schedule and during the interview process. 2.2.2 Recruitment of Participants Participants were required to be adults (defined as 18 or older) and to have had at least one experience in which they perceived something around the human body which they labeled as an aura or energy field. This represents purposive sampling in that participants were selected according to criteria of relevance to the research question and known in advance to be homogenous to the extent that they reported the experience in question. The Information Sheet (Appendix B) accompanying the Consent Form (Appendix C) asked any prospective participant not to volunteer for the study if their experience occurred during a period of mental illness or immediately following the ingestion of drugs. This exclusion was included in order to protect participants, and to exclude reports of experiences that may be directly related to these circumstances. Participants were recruited via acquaintances, colleagues and referra
