The purpose of this study was to explore the nature of the relationship between a continuous performance test (CPT) and teachers' ratings of behavior. Assessment data were archival in nature. One hundred-one children from one rural, middle-class, predominately Caucasian school district in a Midwestern state were selected who had taken the Test of Variables of Attention (TOVA) and whose teachers had completed the Attention Deficit Disorders Evaluation ScaleSchool Version (ADDES) and the Child Behavior ChecklistTeacher Report Form (TRF). Of this group 46 had been referred for Attention-Deficit/Hyperactivity Disorder (ADHD) and/or learning difficulties and 55 had participated in a local norming project for the TOVA.Descriptive statistics were found for CPT variables and teachers' ratings of behavior for all participants, boys and girls separately, and referred and nonreferred separately. The research question was investigated using a matrix of partial correlations controlled for age. TOVA variables included Omissions, Commissions, Response Time, Response Time Variability, Anticipatory Responses, and Multiple Responses. Teacher's rating scale variables included the ADDES Total and subscales Inattention, Impulsive, and Hyperactive as well as the TRF Attention Problems, and Aggressive Behavior.Research provided support that TOVA Omissions and Commissions are valid indicators of ADHD as measured by teachers' ratings of behavior. Response Time Variability and Multiple Responses may be valid indicators of generalized behavior dysfunction as measured by teachers' ratings of behavior. Anticipatory Responses and Response Time may aid in distinguishing ADHD with and without hyperactivity but further research is recommended. / Department of Educational Psychology

M.Ed. (Educational Psychology) / This research inquiry employs the Rasch model of measurement to assess the contemporary quality of the items that constitute an intelligence test developed in South Africa during the 1980s. The Rasch model of measurement will be used as an analytical tool for exploring the quality of items constituting the performance scales of a translated version of the Junior South African Intelligence Scales (JSAIS). The JSAIS was translated into Sesotho and was used to assess grade 1 Sesotho home language learners. This study is part of the Soweto Panel Research Programme (SPRP), which aims to investigate the development of children in a specific Soweto school from preschool (grade R, age 5 and 6) to the end of the Foundation Phase (grade 3). Within this school, the research projects include the assessment of cognitive abilities, numeracy, literacy and the households of the children. I am involved in assessing the cognitive abilities of these children and work in collaboration with three Educational Psychology Master’s students from the University of Johannesburg. The cognitive abilities project aims to assess and track the cognitive development of young children from grade R to grade 3 over a period of four years. Cognitive development focuses on how children learn, process information and attain a veridical view of the world (Gopnik & Meltzoff, 1997), it entails the development of the thinking and organizing systems of the mind, and is composed of language, thinking, reasoning, problem solving, and memory development (Oakley, 2004).

Despite the concept of twins and twinning being a highly explored area of research for many years, limited research has been conducted on the comparison of first and second born twin development. The nature of twins leads people to believe that twins will present with similar characteristics, however, this study explores the possibility that due to their ordinal position they could in fact present with differing characteristics and could differ developmentally. The early holistic development of a child influences the rest of their lives. Concerning twins, the development of individuality and self-knowledge is especially important. Theorists, such as Piaget (1950), propose that child development takes place in stages and that although the order in which children proceed through these stages is the same, the pace at which this takes place can vary. The necessity of monitoring the child’s journey through these stages highlights the value of child developmental assessment. This form of assessment needs to be holistic, needs to involve a multidisciplinary team of professionals and needs to utilize assessment measures that are valid, reliable, culture-fair and standardized. The Griffiths Mental Development Scales-Extended Revised (GMDS-ER) is one such measure. This study, focusing on twin development, aimed to contribute and provide valuable information to a larger research project that is currently under way aiming to increase the applicability of the Griffiths Mental Development Scales-Extended Revised (GMDS-ER) in the South African context. The primary aim of the study, however, was to explore and compare the performance of normal first born and second born twins, aged between 2 and 8 years 4 months old, on the GMDS-ER. The purpose of the study was to generate information on the relationship between first born twins’ general development and second born twins’ general development. An exploratory, descriptive quantitative design was used. Participants were selected through a combination of non-probability purposive, convenience and snowball sampling. Data was analysed using descriptive statistics and dependent sample t-tests were employed to compare the General Quotients (GQ’s) of the first and second born twins in the sample. Results showed that no significant differences were found between the first and second born twins’ general development. Information generated from this study contributed to 1) child development research; 2) twin developmental research within a South African context; and 3) a greater group of studies on the GMDS-ER, currently underway in the United Kingdom and South Africa, aiming to contribute to the international credibility of this measure

M.Ed. (Educational Psychology) / The picturesque landscape of South Africa is woven by the rich threads of diverse languages, cultures and beliefs. Despite the inherent differences of the different groups in this country, a common golden thread lies in the imparting of knowledge, values and beliefs from one generation to the next. This is often done formally, in the school environment, where children learn, develop and grow. The potential of children should be harnessed in an environment that is conducive to maximising the strengths and minimising their weaknesses. One domain is in the psychological testing arena where children’s cognitive abilities are assessed. The Junior South African Individual Scale (JSAIS) as an assessment measure is currently being used by psychologists despite the last norming having taken place in 1984 and the norms not being representative of the South African population. In an endeavour to transition from the past monolingual and monocultural practices, the JSAIS has been translated into isiZulu to eliminate any possible language barriers to participants. However, it is evident that translating tests is a risky procedure and every effort should be made to adhere to criteria proposed by the International Test Commission (ITC) to minimise cultural bias. One such way, is to thoroughly investigate the psychometric qualities of translated tests. The participants of the research are children in the Grade 1 isiZulu class at school in Soweto where research is being conducted. This longitudinal research project is a collaborative effort between the University of Basel, Switzerland and the Centre for Education Practice Research (CEPR) at the University of Johannesburg. The aim of this study was to apply a Rasch Analysis to the Numerical Intelligence Quotient Eight (NUM Scale) of an isiZulu translation of the Junior South African Individual Scales (JSAIS) to determine the quality of the items in relation to the ability of participants in the sample group. As an exploratory, quantitative study, the findings suggest that the JSAIS has some strong psychometric properties and that adaptation, translation and renorming of the test should be conducted in future studies. The findings of this study show that the data generated varied in its fit of the Rasch Model. While findings confirm that the numerical subtests of the Number and Quantity are valid measures of the construct for which it was designed, it is recommended that further studies be conducted into the equivalence of the isiZulu translated JSAIS, the further testing of larger samples of participants and the reduction of cultural loading on items. The information gleaned from this study regarding the misfitting of items, item difficulty and overlapping should also be considered to enhance the quality of this test and thereby maintaining the tenets of our new, modern democracy in South Africa.

The primary aim of this research was to determine whether teachers in their initial or in-service training have acquired a basic knowledge of the interpretation of children's drawings of human figure. A literature study was done in which the focus was placed on major aspects such as: • The normal development of children's drawings according to different stages, and • Those drawings that deviate from the normal development and their implications. • Reliability of children's drawings as a projective tool. A measuring instrument was developed in order to measure the basic knowledge of teachers with regard to the interpretation of children's drawings of human figure. The results of the empirical research indicated that teachers have limited basic knowledge with regard to the interpretation of children's drawings. The educational implications with reference to teachers, education system and other professionals were discussed. Recommendations for further research on similar topics were made. / Educational Studies / M. Ed. (with specialisation in Guidance and Counselling)

Summaries in Afrikaans and English / Text in Afrikaans / Die waarde van visueel-perseptuele skoling of terapie vir visueel-perseptueel gestremde leerlinge as 'n subgroep van leergestremdheid, is reeds vir dekades 'n omstrede aangeleentheid. Hierdie omstredenheid is ondersoek aan die hand van sewe internasionaal erkende psigometriese toetse. Die interne konsekwentheidskoeffisiente van hierdie toetse het vir die huidige studie van 0,62 tot 0,95 gestrek. 'n Faktorontleding van die toetsinterkorrelasies het 'n gemeenskaplike faktor blootgele. Ses toetse was primer visueel-perseptueel, en Goodenough <1926> se skaal is vir die bepaling van intelligensie gebruik. Bykomend hiertoe, is leerlinge se prestasies in hul eerste taal, wiskunde en skrif gebruik om die effek van terapie te bepaal. Proefpersone is as visueel-perseptueel gestremd gediagnoseer deur 'n opvoedkundige sielkundige en 'n visuele skolingsentrum in Pretoria, waar eksper imentele leerlinge terapie ontvang het. Hierdie diagnoses is deur die Test for Visual Analysis Skills wat beduidend tussen normale en visueelperseptueel gestremdes onderskei, bevestig. Die toets se geldigheid vir Suid-Afrikaanse omstandighede is in 'n voorstudie bepaal. Honderd en ses, ses- tot negejarige proefpersone (82 seuns en 24 dogters>, van normale intelligensie, gesigskerpte en gehoor, is betrek. Drie en vyftig het die eksperimentele groep gevorm wat onderverdeel is in 32 wat terapie voltooi het, en 21 wat nie het nie. Hierdie leerlinge is individueel afgepaar met kontroleleerlinge van dieselfde geslag, ouderdom, huistaal, sosio-ekonomiese status en skoolstanderd. Eksperimentele leerlinge het visuele terapie in n breer groepsverband vir een uur per week ontvang. Terapieperiodes het van 4 tot 15 maande gewissel. Die eksperimentele ontwerp was 'n voortoets-natoets-tweegroepontwerp. t-Toetse vir afhanklike (afgepaarde) groepe is uitgevoer op die verskille tussen voor- en natoetstellings, asook tussen die eksperimentele en kontrolegroepe. Geeneen van die primer visueel-oerseptuele meettegnieke het beduidende resultate opgelewer nie. Dit is aanduidend van die ondoeltreffendheid van visueel-perseptuele terapie om die tekorte waarop dit gemik is, reg te stel. Die waarde van visueel-perseptueie terapie is inteendeel beperk tot 'n oorhoofse verbetering in konseptualisering en intellektuele ryping by die groep wat terapie voltooi het. Skrif was die enigste vak wat by dieselfde groep beduidend verbeter het. Hierdie resultaat is egter twyfelagtig vanwee beoordelingstekorte. / The value of visual perceptual training or therapy, to visually perceptually impaired pupils as a subgroup of the learning disabled, has been a controversy far decades. This controversy was investigated by means of seven internationally recognised psychometric tests. The internal consistency coefficients of these tests for the present study ranged from 0,62 to 0,95. A factor analysis of test intercorrelations revealed a common factor. Six tests were primarily visual perceptual, whilst the Goodenough (1926) scale determined intelligence. Additionally, pupils' performance in their first language, mathematics and writing, was used to assess the therapeutic effect. Subjects were diagnosed as visually perceptually impaired by an educational psychologist and a visual training centre in Pretoria where experimental pupils received therapy. These diagnoses were confirmed by the Test for Visual Analysis Skills, which significantly differentiates between the normal and visually perceptually impaired. This test's validity for South African circumstances was determined in a prestudy. One hundred and six, six to nine year old subjects <82 boys and 24 girls>, of normal intelligence, visual acuity and hearing, were involved. Fifty three formed the experimental group which was subdivided in 32 who completed therapy, and 21 who did not. These pupils were individualiy matched with controls of similar sex, age, home language, socio economic status and school standard. Experimental pupils received visual therapy within a broader group context for one hour per week. Therapy periods fluctuated between 4 and 15 months. The experimental design was a pretest-posttest two group design. t-Tests for dependant <matched) groups were conducted on the differences between pre and oosttest scores, as well as between the experimental and control groups. None of the primarily visual perceptual tests revealed significant results. This signifies the inefficiency of visual perceptual therapy to rectify the deficits at which it is directed. The value of visual perceptual therapy is, on the contrary, restricted to an overall improvement in conceptualization and intellectual maturation within the group which completed therapy. Writing was the only subject which improved significantly within the same group. However, this result is dubious, due to evaluation deficits. / Psychology / D.Litt. et Phil. (Psychology)
