Results show that the retarded group was significantly more cooperative than the nonretarded group, and the 6-7 year retarded group was more cooperative than the 11-12-year retarded group. (Authors/CB)

The relation of CA, MA, and IQ to conservation was examined by comparing the performance of bright, normal, and retarded children matched on the critical MA of six years. (Author)

Results indicate that within the limitations of this study there is evidence that children with superior" intelligence showed more mature response patterns on Piaget-type tasks than children of the same age with average" intelligence test scores. (Author)

In this study, the relationship between a refined measure of the learning environment of the home and the levels and profiles of a set of mental ability scores of children from five Canadian ethnic groups was examined. Significant group differences persisted in the verbal, number, and reasoning scores. (Author/JMB)

This report is a summary of a doctoral dissertation at the University of Oklahoma by the first author, under the direction of the second author. (RJ)

Correlations between McCarthy Scales of Children's Abilities and teachers' ratings of academic achievement were investigated. McCarthy Scales are useful in predicting achievement of normal children, but further research is needed with learning disabled students. Use of teachers' rating scales with low functioning children is discussed in light of…

Subjects with higher verbal than performance IQ's achieved significantly poorer Pascal-Suttell Bender-Gestalt scores than subjects with higher performance over verbal IQ's. The latter subjects were more likely to have dropped out of high school and to have spent some time in prison. (Author/RD)

Examined the influence of intelligence level on the performance of children (N=121), aged 9-14, on the Halstead Reitan Neuropsychological Test Battery. Results indicated a significant influence of IQ on level of performance on six of 14 measures. Tests of problem-solving abilities, language skills, and auditory perceptual analysis were most…

Groups of 270 Black and 270 White children drawn from the national stratified random sample used in the standardization of the Wechsler Intelligence Scale for Children-Revised (WISC-R) were matched on age, sex, and WISC-R Full-Scale Intelligence Quotient to facilitate investigation of the patterns of specific cognitive abilities.

The relative influence of scholastic achievement, intelligence, athletic ability, and ethnic origin on the formation of friendships among pupils in two Israel elementary schools was explored. The most important factor was found to be similar academic achievement, followed by intelligence and athletic achievement. (Authors/PP)

An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

Explored the relationship of self-drawings to self-concept in mentally retarded youths. Overall self-drawing score, size of self-drawing, age and sex shared significant variance with self-concept scores. These variables can provide additional information in evaluating the self-concept of the mentally retarded. (Author)

This study sought to replicate findings from a clinical sample of boys with two normal day school samples, ages 9-10 and 13-14. Results showed a significant interaction effect only for the older group. (Author/SJL)
