Twenty-six children ranging in age from 6 to 12 years whose tested IQ's were over 160 were tested on three Piagetian tasks of advanced concrete operations and two tests of formal operations. All children passed all concrete operations problems, but only four of the oldest boys passed the formal operations tasks. Findings are discussed in terms of…

One hundred deaf children with deaf parents performed significantly better than 100 deaf children with hearing parents on all performance subtest of the Wechsler Intelligence Scale for Children-Revised. (CL)

Forty college students were administered a self-rating scale for intelligence along with several actual ability measures, including the Concept Mastery Test and "breadth" and "depth" indices based on the Weschsler Adult Intelligence Scale Similarities subtest. (MS)

Differing findings exist on how Defining Issues Test (DIT) scores relate to intelligence. Further study is needed in order to address aspects of intellect not previously considered and to address how these relationships rival studies that have compared indices of intellect with constructs similar to DIT scores. In the present study, a sample of…

A QUALITATIVE AND CLINICAL ANALYSIS OF COGNITIVE FUNCTIONING WAS DETERMINED BY ADMINISTRATION OF THE STANDFORD-BINET INTELLIGENCE SCALE AND THE WECHSLER INTELLIGENCE SCALE FOR CHILDREN TO A SAMPLE OF 65 NORMAL CHILDREN. EXAMINATIONS AND OBSERVATIONS WERE MADE FOR EACH CHILD DURING HIS INFANCY, PRESCHOOL, LATENCY, AND PREPUBERTY PERIODS. ANALYSIS…

Five measures of intellectual level (IQ, MA, teachers' estimates of intelligence, level of object permanence, and representation of causality) were correlated with effectance variables and with each other for 42 quadraplegics (one to 12 years). Results reveal some relationship between intellectual level and effectance, although cognitive ability…

Elementary school children were tested individually on their learning of mathematics and on Piagetian tests of concrete operations. Younger children were found to be inferior to older children in their success on learning tasks. (ST)

Recent literature suggests a causal link between malnutrition and impaired cognitive development. A selective literature review indicates that the presence or absence of such a link cannot be established. A reanalysis of an experiment indicated after four years of treatment there was no association between cognitive and nutritional status.…

This document examines the use of measurement tools to evaluate children's psychological development. The first part of the document discusses the identification and quantification of developmental landmarks and the reasons for evaluation. The second part reviews several evaluation instruments. The Ruth Griffiths mental development scales are used…

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old educable mentally retarded students, who were matched according to sex and race. Results suggest that many children classified as "Borderline" or slightly above the WISC will be classified as "Mentally Deficient" by…

Appraised cognitive patterning and development for 142 pairs of twins at 4, 5, and 6 years of age. From the results it was inferred that within a broad range of home environments, the genotype exerts a significant influence on the child's cognitive development. (Author/SDH)
