The general purpose of this study was to investigate the relationship between neuropsychological tests scores and perfusion deficits, based upon measures of regional cerebral blood flow (rCBF) taken from the single photon emission computed tomography (SPECT) scans of patients suffering from dementia of the Alzheimer type (DAT). The study was designed to determine if DAT patients categorized as having left hemisphere, right hemisphere, diffuse, or an absence of perfusion deficits, as measured by SPECT, would be accurately grouped into their respective categories, and if they would exhibit the corresponding neuropsychological deficiencies usually associated with lateral hemispheric asymmetries.Selected subjects were 80 right handed, DAT patients from the North Broward Medical Center - Memory Disorder Center, in Pompono Beach, Florida, who had been administered a neuropsychological test battery, and a SPECT scan.Through several ANOVA's that were calculated for each of the neuropsychological variables, it was concluded that DAT patients who suffered from perfusion deficits exhibited significantly lower levels of neuropsychological functioning than DAT patients without perfusion deficits.These analyses revealed significantly lower levels of neuropsychological performance in the perfusion deficit group on the combination of left hemisphere WAIS-R subtests (Information, Similarities & Vocabulary), WMS - Logical Story (p < .01), WRAT-R Reading, WRAT-R Mathematics, WMS Paired Associates, and the Rey Complex Figure (p < .05).A separate step-wise discriminant function analysis indicated that a combination of the neuropsychological variables could not accurately classify the DAT patients into their respective right hemisphere, left hemisphere, diffuse, or absence of perfusion deficit groups. The discriminant function classified only 32.5% of the grouped cases accurately. Of the original thirteen neuropsychological variables, only Paired Associates immediate recall of the WMS entered the discriminant analysis equation. This accounted for only 23% of the total variability that could be explained by differences between the perfusion deficit groups. In several post hoc ANOVA's using the Bonferroni method of multiple comparisons, it was revealed that the absence of perfusion deficit group scored significantly higher than the other groups on the majority of the left hemisphere neuropsychological measures. However, none of the right hemisphere neuropsychological measures attained significance. / Department of Educational Psychology

Three reaction time experiments were conducted to determine when and how memory for the normal left-right orientation of letters is mediated by the developing brain. In each experiment, participants identified forward and backward letters presented unilaterally to each visual field and thus to each hemisphere (VF-H). / The main findings were as follows: (1) For the five-year-olds, no VF-H differences were found in the speed of identifying either forward or backward letters or in the difference in speed between forward and backward letters. (2) The seven-year-olds identified forward letters faster than backward letters in the right visual field-left hemisphere (RVF-LH) with the contralateral, right hand, and the boys, unlike the girls, also showed this difference in the left visual field-right hemisphere (LVF-RH) independent of the responding hand. (3) Performance of the nine-year-olds was similar to that of the seven-year-olds. (4) Adults identified forward letters faster than backward letters in the RVF-LH with each hand, whereas in the LVF-RH this difference was found for the ipsilateral, right but not for the contralateral, left hand. / Support was provided for the Corballis-Beale (1976) hypothesis, and discussion centered on the implications of the results for the development of cerebral lateralization of memory for the normal left-right orientation of letters in normal and reading disabled children.

M.A. / To what extent can and does the left hemisphere and the right hemisphere become involved in the teaching of Afrikaans as a first language in the secondary school? According to the Transvaal Education Department syllabus it must be irrevocably accepted that most of the teaching of Afrikaans as a first language is presented by the left hemisphere. Latent abilities to understand in the present day scholar can only be developed to their full potential if the right hemisphere of the brain is stimulated and is allowed full extension. As a result of the fact that the right hemisphere is specialized for holistic processing its capacity can be increased by tasks which develop positive emotional images and activities. By way of introduction the origin of left and right hemispheric studies is given. Joseph Bogen feels that the community overvalues the domination of the left hemisphere to the detriment of the right hemisphere. A few theories and methods dealing with the laterality of thought have been closely examined and the working of a few principles of Suggestopedia are briefly discussed...
