The purpose of the present study is to compare the 1959 revision of the Columbia Mental Maturity Scale (CMMS) with the Wechsler Intelligence Scale for Children (WISC) for use as a psychometric instrument for determining the mental ability of mentally retarded male children.

The specific objectives of this investigation are as follows: 1. To determine which half -- verbal half or performance half -- of the Wechsler-Bellevue Intelligence Test contributes most to total intelligence quotient for schizophrenics. 2. To determine whether any significant correlation exists between test scores and patterns of schizophrenics and normals. 3. To determine whether there exists any premature aging process in schizophrenics.

The Rorschach records and Wechsler Intelligence Scale scores of sixty-six children between the ages of 5 and 13 were compared. Subjects in each group were from one of three conditions: children who have documented histories of physical abuse, children referred for clinical intervention with no history of abuse, and a community sample of children with no documented history of abuse or psychological treatment. Data from the groups were analyzed to examine evidence of increased reliance on ego functions related to motor activity and concurrent deficits in other areas of ego function by subjects in the physical abuse group. Results revealed that the physical abuse group showed a greater tendency toward color-dominant responses on the Rorschach than the comparison groups and that the Community control group produced records with lower extended form quality than the clinical groups. No significant differences were found for Performance/Verbal IQ split, EB style, Cooperative Movement or Aggressive content.

The purpose of this research was to investigate possible examiner bias in scoring the Verbal subtests of the Wechsler Intelligence Scale for Children (Revised) due to the level of facial attractiveness of the child. Sex of the child and sex of the research subject were also included as independent variables. No main effect for attractiveness or sex x attractiveness interactions were found. Thus, little evidence emerged to suggest attractiveness stereotyping effects in an intelligence testing context. However, female children received significantly higher Comprehension and total Verbal scores than did male children. In addition, while male subjects did not provide differential Verbal scores for male and female children, female subjects tended to be biased toward female children, regardless of attractiveness level. A secondary goal of this study was to determine if the research subjects differentially attributed positive characteristics to attractive versus unattractive children. Indeed, it was empirically established that, in this testing environment, adults attributed more positive personality and social characteristics to attractive than unattractive children. Implications for clinicians/diagnosticians are discussed. It is suggested that future research attempt to delineate a continuum of diagnostic measures wherein one pole represents objective measures with little risk of bias and the other pole is the extreme of subjective instruments with high resk of examiner bias.

This investigation concerns the intelligence of the Negro population in relation to the white population. There is a considerable difference of opinion relating to the intelligence of the Negro. Some students in the field contend that the Negro's intelligence, as measured by the tests available for all individuals, is naturally lower due to hereditary factors. Other investigators (these seem to be in the majority1 believe that environment plays the major role in lowering their ability to gain a comparable score with white individuals.

Recent national longitudinal studies of special education students indicate that schools should concentrate on developing students' skills matched to the requirements of their potential occupations. Evidence suggests that the experience of career development among adolescents with learning disabilities is especially frustrating without early exploration and planning. This study investigates the value of using available psychometric data in assisting the school psychologist and other professionals to make initial exploratory estimates of vocational aptitude without referring the student for specialized vocational assessment. General Aptitude Test Battery (GATB) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) scores were used in multiple regression analyses to examine the predictive relationships existing between the two instruments. The population studied included 172 adolescents wi th learning disabilities enrolled in a public school division. The analyses in this study reveal a high degree of validity between the GATB and WAIS-R. However, the prediction equation appears unsuitable for using the WAIS-R subtests for predicting GATB aptitudes. Aptitude F explains the highest degree of variance. Other squared multiple regressions range as low as .13 for Aptitude Q to as high as .52 for Aptitude S. Results suggest that even though the GATB and WAIS-R share common variance, there is enough independent information provided by each test to warrant employing both in order to insure that the students' vocational aptitudes are fully diagnosed. Implications for school psychologists and other professionals doing exploratory assessments of vocational aptitude from available WAIS-R subtests are discussed, as are assessment issues regarding adolescents with learning disabilities. / Ph.

A growing body of opinion, research, and legislation [PL 98-524] implies that school psychological evaluations with adolescents and young adults should routinely include estimates of vocational interests and aptitude. Certainly all secondary level special education evaluations should include this important vocational component. Evidence suggests that the experience of career development among learning disabled young adults is particularly frustrating and difficult without early planning and exploration of options. This study examines the utility of traditionally available psychometric data in assisting the clinician make initial, exploratory estimates of vocational aptitude without referring the client for specialized testing. Wechsler Adult Intelligence Scale - Revised [WAIS-R], and General Aptitude Test Battery [GATB] scores were subjected to a multivariate, canonical correlation analysis to examine the overlap among constructs estimated by these sets of variables. The sample was composed of 148 learning disabled young adults enrolled in a state supported vocational rehabilitation program. Three significant canonical correlations were interpreted. The redundancy index showed that 34% of the variance in GATB aptitudes is explained by three linear combinations of WAIS-R subtest scaled scores, and that 31% of the WAIS-R subtest variance is predictable from three composites of GATB aptitude scores. Analysis of the structure correlations suggests that the first pair of canonical variates [Rc = .87] share a general intelligence, or verbal comprehension factor. A second pair [Rc= .73] share a perceptual and motor coordination construct. The third pair of canonical variates [Rc = .61] define a perceptual speed, or psychomotor construct that overlaps both the GATB and the WAIS-R set of test scores. There is evidence that GATB and WAIS-R estimate similar, but essentially independent dimensions of the same three psychoeducational constructs. WAIS-R may provide better estimates of fluid ability than GATB; and GATB may provide better estimates of crystallized ability than WAIS-R. Clinical implications for psychologists making exploratory estimates of vocational ability and aptitude from clinical profiles of WAIS-R scaled scores are discussed. Assessment issues with respect to the learning disabled young adult are also presented. [175 references] / Ed. D.
