Cross-validated the factor analysis of the McCarthy Scales and determined construct validity for children who score one standard deviation below the normative mean on general cognitive ability. Findings discourage interpretation of the Quantitative Scale for school-age children with General Cognitive Indexes below 84. (Author)

Assessed the relationship of stress to decline in intellectual abilities in women aged 65-92. Found stress was related to the ratio used to estimate decline. Changes in personal health and health of a family member were positively related and vacations were negatively related to decline in intellectual functioning. (Author)

Analyzed 400 Wechsler Intelligence Scale for Children (Revised) (WISC-R) protocols to determine whether an abbreviated form could be identified that would be cost-effective. Results indicated that the derived prediction equation could be applied to the results of five designated WISC-R subtests to predict range of intellectual functioning with…

Concludes that the Slosson Intelligence Test and the Leiter International Performance Scale measure only limited aspects of reading disabled students' abilities as measured by the Weschsler Intelligence Scale for Children--Revised. (FL)

Determined if Wechsler Intelligence Scale for Children-Revised subtest patterns would differentiate the performance of emotionally disturbed and learning-disabled children. Subtests differentiated significantly between diagnostic categories. Learning-disabled children performed predictively poorer on block design, picture arrangement, and object…

Pairs of brothers were individually examined with Wechsler Adult Intelligence Scale some 10 months apart by an experienced clinical psychologist unaware of the consanguineous relationship. Correlation of .42 for Full Scale IQ is consistent with median correlation reported by Erlenmeyer-Kimling and Jarvik in their 1963 literature review.…

Examined the validity of a subtest combination as an estimate of the Wechsler Intelligence Scale For Children (Revised) Full Scale IQ. Satisfactory correlations were found between the short and full scale IQ. The short form did not allow precise IQ estimation but shows promise as a screening device. (Author)

Although differences in composite Wechsler Intelligence Scale for Children--Revised (WISC-R) measures were exhibited by children with mental retardation, learning disabilities, and psychological or behavioral disorders, few significant group differences were exhibited. Caution is necessary in making diagnostic statements based on WISC-R profile…

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

The validity and reliability of the Peabody Picture Vocabulary Test was estimated with emotionally disturbed adolescents. Results indicated that the power of the test to predict future achievement of emotionally disturbed adolescents is comparable to that expected for normals. (Author)

Sattler's standard deviation technique for interpreting strengths and weaknesses on the Stanford-Binet Intelligence Scale has been simplified by Kaufman and Waterstreet in the form of an easy-to-use table. A refinement of their table is presented, with an example to demonstrate its use. (Author/CTM)

Subjects between the ages of 50 and 86 years were given portions of the Halstead-Reitan Neuropsychological Test Battery, the Wechsler Memory Scale, and the Wechsler Adult Intelligence Scale. Younger subjects performed significantly better than older subjects on 10 of the 18 neuropsychological measures used. (Author/BEF)

Forty-seven lead poisoned children, treated and without encephalopathy, were compared with sibling controls on perceptual-verbal pattern comparisons of subtests of the Wechsler Intelligence Scale for Children (WISC) to determine whether there was brain damage. Results indicated that lead poisoning, treated, and without encephalopathy, does not…

Demonstrates the need for schools to clearly define diagnostic categories such as learning disabilities (LD). These LD students were considerably different from LD students in other studies. They performed on grade level according to the Wide Range Achievement Test, but significantly below their peers in actual classroom performance. (Author)

Examined the effects of different types of reinforcement on the performance of Black males diagnosed as being mildly mentally retarded. Children given tangible or culturally relevant rewards obtained significantly higher scores than did children given either no reinforcement or traditional social reinforcement. (Author)
