    An analysis of performance on the Rey auditory-verbal learning test after traumatic brain injury, and its association with reported everyday memory performance : a thesis presented in partial fulfillment of the requirements for a degree of Master of Arts in Psychology at Massey University
    (Massey University, 2002) McGill, Roslyn A
    The current study was conducted in two parts. Study 1 examined the Rey Auditory-Verbal Learning Test (AVLT) performance of 353 individuals who had been referred to an outpatient psychology clinic having sustained a traumatic brain injury (TBI). Individuals were divided into subgroups based on their patterns of performance on the AVLT. Individuals with low trial 1 scores were divided into three groups based on their subsequent AVLT performance. Individuals with low delayed-recall scores were divided into four groups based on their performance on preceding AVLT trials. For the TBI group as a whole, significant correlations were found between AVLT scores and age, education, and general intelligence (as measured by verbal IQ). Study 2 investigated relative ratings of everyday memory performance on the Patient Competency Rating Scale). This data was available for 82 of the individuals in the initial sample. The relationship between reported everyday memory performance and test performance on the AVLT was examined for this group. No significant correlations were found between these two variables. Low correlations were found between patient and relative ratings on the PCRS. Individuals were divided in four groups based on their everyday memory and test performance. Individuals with low everyday memory performance were found to have a similar type and number of difficulties, regardless of their AVLT performance. The results of this study highlight the varied performance of individuals after TBI, both on memory tests such as the AVLT and reported everyday memory performance. The AVLT should not be used to predict the level of difficulty in daily life as the correlations are not significant.

    The effects of traumatic brain injury on logical memory : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in psychology at Massey University
    (Massey University, 1994) Harris, Joanna Lee
    The Logical Memory subtest of the Wechsler Memory Scale - Revised was administered to 80 subjects with mild to severe traumatic brain-injury (TBI) and 49 Control subjects. Quantitatively TBI subjects scored significantly below Control subjects and forgot more between the immediate and delayed testing. TBI clients also recalled more of Story B than Story A, as did all the male subjects. Female subjects performed better than the male subjects overall, TBI males scored as well as Control males which was unexpected. When the order of presentation was reversed for random Control subjects results show that performance was better for the first story presented. After the LM passages were modifying to eliminate various Americanisms, the Control subjects randomly selected performed better on the NZ version, although these results were not significant. When the demographic variables of the TBI and Control groups were compared the only significant differences were between the 21 - 30 year old subjects and the Pakeha subjects. Qualitative analysis was attempted in order to introduce a new domain of research and suggestions for improved scoring criteria. The evidence suggest that TBI subjects tend to focus on isolated details, have difficulty remembering proper nouns, and have more bizarre intrusion errors than Control subjects. Control subjects were more inclined to translate the stories into their own words and remember more of the overall gist.
