Welcome to the refereed proceedings of the inaugural Doing Psychology: Manawatu Doctoral Research Symposium 2011. The symposium, held in the School of Psychology at Massey University, Manawatu Campus on December 7, showcased the diverse range of doctoral research undertaken at the Manawatu Campus. Papers were submitted by authors who were at various stages of their research. The symposium was a doctoral student initiative in that the proceedings were organised, edited and peer reviewed by doctoral candidates, graduands and recent graduates. We were also fortunate to have international reviewers from Canada and Norway. The symposium was a chance for candidates to disseminate and discuss their research in a supportive environment. It was also an opportunity to both present and publish a concise paper in an online edited book of proceedings. Candidates gained experience in writing and structuring a concise paper to a set format for publication and participating through blind peer review. The symposium was opened by Associate Professor Mandy Morgan, the Head of School. There were eight paper presentations covering a wide range of topics and methodologies as well as great discussion by staff and students. We thank everyone who supported the symposium and made it such a memorable and enjoyable event. We look forward to seeing many of you again at the next symposium in 2012.

    The Bewildered Brain: Asymmetric Brain Activity as a Source of Cognitive Impairment in Depression
    (Massey University, 2011) Campbell, Kathryn; Hill, Stephen; Podd, John
    Individuals with depression commonly complain about cognitive deficits such as memory loss and poor decision making ability (Lahr, Beblo, & Hartje, 2007). However, despite considerable research, no single profile of cognitive deficits in depression has emerged (Ravnkilde et al., 2002). This may be a result of heterogeneity within the diagnostic category of depression. While typically diagnosed as a single disorder, the symptoms of depression may stem from different neurobiological causes leading to different profiles of cognitive deficits. Shenal, Harrison, and Demaree (2003) theorised that subtypes of depression could arise from dysfunctional brain activity in each of the quadrants of the brain (right frontal, left frontal, right posterior, and left posterior). For example, reduced left frontal activity in depression may be associated with impairments in tasks reliant on left frontal regions. Little research has directly investigated the possible link between variability in cognitive deficits and different patterns of dysfunctional brain activity in depression. The current paper reviews evidence for this link by describing depressed individuals’ performance on lateralised cognitive tasks, and discusses possibilities for future research.
