The majority of children with Fetal Alcohol Spectrum Disorder (FASD) have comorbid Attention-Deficit Hyperactivity Disorder (95%; Fryer et al., 2007). The goal of this study was to compare the neuropsychological and adaptive skills profiles of children with Attention-Deficit/Hyperactivity Disorder (ADHD) with or without comorbid FASD in order to improve interventions for both of these populations. This study paid particular attention to neurological, cognitive, and adaptive skills strengths and weaknesses in children with ADHD/FASD and children with ADHD without comorbid FASD. By identifying these strengths and weaknesses recommendations were able to be made to help the functioning of each of children with ADHD/FASD and children with ADHD in their home, community, and school environments based on their neuropsychological and adaptive skills profiles. Neurologically, children with ADHD/FASD and children with ADHD have been shown to have impairment in the basal ganglia, cerebellum, corpus callosum, frontal lobes, hippocampus, hypothalamus, occipital lobes, parietal lobes, temporal lobes, and thalamus. Cognitively, children with ADHD have been shown to have difficulty in areas such as working memory and processing speed with less significant deficiencies in verbal ability and perceptual organization whereas children with ADHD/FASD have shown impairment in all of these cognitive abilities. When compared to typically developing children with approximately the same level of general intelligence, children with ADHD have been shown to obtain lower standard scores in all domains of adaptive functioning and children with FASD have been shown to demonstrate significant adaptive skills deficits throughout the lifespan. This study used specialized statistical procedures including Multivariate Analysis of Variance (MANOVA), Discriminant Analysis (DA), and Classification and Regression Tree (CART) in order to investigate the neuropsychological and adaptive skills in 81 children with ADHD/FASD and 147 children with ADHD. The statistical analyses indicated that children with ADHD/FASD and children with ADHD have similar cognitive and adaptive skills profiles; however, the children with comorbid ADHD/FASD were significantly more impaired in verbal ability, perceptual reasoning, working memory, processing speed, and overall adaptive skills. The current study took a step forward in helping to make diagnostic decisions based on the similarities and differences between children with ADHD with and without comorbid FASD. Given the data from the current study indicating the significant differences in cognitive and adaptive skills in these two samples, it is imperative that psychopharmacological interventions be tailored to these two seemingly similar yet different groups, especially as these two groups may respond differently to stimulant medication, the first line of medicinal treatment for ADHD. Children with ADHD/FASD should also be treated with more intense interventions in the home, community, and school than children with ADHD. / Department of Educational Psychology

The newly developed Differential Aptitude Test Form S (DAT) does not give an indication of general intelligence or expected achievement in Grade 9. The aim of the current study was to determine the relationships of the aptitude subtests (measured by the DAT) with intelligence and achievement. Two affective factors, motivation and self-concept, as well as study orientation, were included as variables predicting achievement. An empirical study was carried out in which 60 Grade 9 learners were tested. The variables were measured using reliable instruments. Correlations were calculated and multiple regression analyses used to predict achievement. Moderate to high positive correlations between aptitude and intelligence were found. Affective factors explained more of the variance in achievement in key subjects than aptitude variables. One conclusion is that Grade 9 achievement measures affective rather than cognitive factors. Recommendations are made regarding the use of the DAT-S in predicting school achievement. / Educational Studies / M.Ed. (Specialisation in Guidance and Counselling)

It has been suggested that the use of standardized intelligence tests is biased against minorities. This study investigates the newly revised Wechsler Intelligence Scale for Children-III in which Wechsler states that the new scale has eliminated biased items. Comparisons of the scores on the WISC-R and the WISC-III of a clinical population of sixteen African American and eighteen Caucasian males, ages ten to sixteen, revealed significant differences between the two groups on the WISC-III. The minority scores decreased predictably from the WISC-R to the WISC-III, but the Caucasian scores increased rather than decreasing. The findings of this study do not support the predictions and goals of revision as stated in the manual of the WISC-III.

South African research into dynamic assessment has contributed to the growing body of international research which supports the efficacy of dynamic assessment in uncovering learning capacity in a variety of populations of learners with special needs. This study investigated the application of dynamic assessment to a sample of black children within a South African township clinic setting. Aged 9-15 years (mean age = 10.96) they had been referred to the clinic with learning difficulties. The experimental group (n=48) was exposed to a group dynamic assessment process, using certain tasks of the Learning Propensity Assessment Device (LPAD). Their performance was assessed prior to and following the mediated learning intervention. Using Analysis of Covariance, comparisons of pre and post-test scores combined with an innovative qualitative scoring method designed by Lurie and Kozulin (1996) yielded positive findings for the experimental group as compared with a control (n=24) not exposed to mediation. Results of the Raven's Coloured Progressive Matrices (RCPM) and the Rey-Osterreith Complex Figure Test (ROCFT), suggest that the intervention yielded changes, not only in the scores attained, but also in the quality of the responses on the post-tests.

Both children and adults share a common, culturally distinct view of what it means to be male or female. These gender stereotypes are pervasive in society and daily social interactions, and influence all aspects of gender development (Golombok & Fivush, 1994). The inherent physical differences of boys and girls may have triggered the speculation and accompanying myths surrounding the existence of gender differences in childhood development. Many people believe that boys and girls follow a different developmental path that lead to gender differences in intellectual ability. An up-to-date and integrative review of theory and research on gender indicates two opposing perspectives on the topic, with substantial information supporting each view. However, this is the first study to examine and compare a sample of South African pre-school boys and girls from a truly holistic developmental perspective on the recently released Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Developmental theorists have emphasized the profound impact early childhood development has on subsequent development, as it shapes the course of an individual’s life. Contemporary cognitive developmental theories, such as Demetriou’s (2000; 2004) developmental model of cognitive development, advance that child development does not progress in a fixed and predictable manner. Instead, Demetriou proposes that development occurs in a wave-like fashion, where the processes and functions of the various levels of the mind may be at differing points in their cycle of development. When one function progresses to a higher level, it unlocks the possibility for another function to advance to a different point in its cycle (Demetriou et al., 2002). As the significance of understanding the process of early childhood development more fully increases, so does the need to establish with more confidence the value and role of developmental assessment in the early identification of problems. The overall purpose of this study was to generate comparative information regarding the general development of a sample of 5- and 6-year-old South African pre-school boys and girls. Specifically, the study aimed to explore and describe the developmental profiles of pre-school boys and girls within the abovementioned age group with respect to their overall performance on the GMDS-ER as well as their performance on the six Subscales. Then, the mean General Quotients (GQ) and developmental profiles of the pre-school boys and girls obtained on the GMDS-ER were compared. An exploratory-descriptive quantitative research method was used. The sample (N = 64) was selected through a combination of non-probability, purposive and convenience xiii sampling. Within this framework, a between-subjects design in which matching was used to control extraneous variables, was employed. Data was analysed using descriptive statistics and independent sample t-tests to compare the GQs of the gender groups. A Hotellings T2 was used to compare the Subscale profiles. No significant gender differences were found when comparing the overall developmental and Subscale profiles of the boys and girls on the GMDS-ER. However, certain interesting trends did emerge from a review of the findings when compared to the literature review and previous studies. The information generated from this study has contributed to our knowledge base of the performance of South African children on the recently released GMDS-ER.

The South African context necessitates developmental assessment measures with particular characteristics. A critical examination of a variety of potential measures indicates that there are very few measures available to meet these specific needs. The GMDS-ER is judged to be one such measure. This study explores the performance of South African children aged 4 to 7 years of age as it relates to that of British children (from the standardisation sample). The samples consisted of normal South African (n=129) and British (n=161) children, where normalcy refers to the absence of sensory, physical, or mental handicap. The study was done in an attempt to explore the suitability of using the GMDS-ER in the South African context. More specifically, the following two aims were pursued: 1. To explore and describe the general development of each of four year groups of a sample of British and South African children by utilising the general developmental quotient of the GMDS-ER 2. To explore and describe the comparative developmental profiles of each of the four year groups of a sample of British and South African children across the six developmental areas represented by the subscales of the GMDS-ER. Descriptive statistics and simple t-tests were used to accomplish Aim 1 and Hotellings T2 tests were mainly used in order to accomplish Aim 2. The major findings of the present study were as follows: 1. South African and British children’s overall performances (as measured by the GMDS-ER GQ) are similar. A great deal of variability exists between the GMDS-ER profiles of normal South African and British children (i.e., when individual subscales and year groups are considered). 3. In general, South African children performed better on the Locomotor and Personal-Social Subscales, while British children performed better on the Language and Practical Reasoning Subscales. Performance on the Eye and Hand Coordination Subscale was similar for the two samples and on the Performance Subscale performance was too variable to come to any general conclusions. In view of the findings, caution with regard to the use of the British-based norms in the South African context is recommended. Recommendations are made for the use of the GMDS-ER to help with the identification of specific classes of disorders in the South African context. Further investigation into the applicability of the GMDS-ER for South African use as well as the establishment of South African norms are final recommendations.
