A study trained 10 5-year-old typical children, 11 5-year-old gifted children, and 11 7-year-old typical children on strategy use. Several differences among groups were found, generally favoring the gifted children in terms of performance and maintenance of strategies. In addition, the gifted children seemed to use categorization strategies…

Explores the generality of findings relating intelligence to Inspection Time (IT), the exposure necessary to judge which of two lines is longer, in two studies using normal children and mentally retarded adults. Results showed the relationship between IT and performance IQ was lower in the mentally retarded group. (JAC)

Two experiments examined whether correlations between IQ and probed serial running memory depend on IQ-related individual differences in the retention of order information in short-term memory. Children's IQ correlated with memory, regardless of whether instructions emphasized serial or free recall; and with recent item but not recent order…

Relationships between six home environment measures, achievement and intelligence tests were examined by stepwise multiple regression analyses for a sample of 60 eight-year old children. Home variables were most successful in predicting achievement test scores, less successful regarding culture-dependent intelligence test scores, and least…

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)

The expert-novice paradigm, which demonstrates the outstanding role of domain-specific knowledge in explaining differences in memory behavior and performance, was examined. Two studies are described which compared memory performance of groups equivalent with regard to domain-specific knowledge but differing in intellectual ability. The hypothesis…

Major visuospatial and verbal abilities were assessed for 197 10-year-olds in Hong Kong and 170 10-year-olds in the United Kingdom. The Hong Kong subjects resembled their Japanese counterparts in having high Searman's "g," exhibiting abstract reasoning ability, high spatial ability, high perceptual speed, and low word fluency.

Swedish longitudinal studies of twins support Scarr-Salapatek's explanation of nature-nurture influences on intelligence. This model predicts more genetic variance in test results for advantaged than disadvantaged groups. Jensen's work, however, suggests equal amounts of variance among different social classes. (Author/CP)

A study assessed whether the effects of computer-assisted practice on visual word recognition differed for 73 Spanish children with reading disabilities with or without aptitude-achievement discrepancy. Computer-assisted intervention improved word recognition. However, children with dyslexia had more difficulties than poor readers during…

This study investigated the effects of classroom composition on achievement. The analysis focused on the assessment of classroom homogeneity with respect to the socioeconomic background and general intelligence of the students. In addition, the extent to which classroom composition affects the standards the teachers employ and how these standards…

A case study of a pair of extremely deprived twin boys focuses on their verbal communication. Talkativeness alone was not regarded as a measure of intelligence, but attention was paid to the less talkative twin's greater use of imaginative speech. Speculations are made on the evolutionary role of creative speech. (IS)
