To examine whether or not retarded individuals have the same structure of intelligence as normal IQ individuals, test scores from the Wechsler Intelligence Scale for Children-Revised (WISC-R), Reitan's Trail Making Test (TMT), and Beery's Developmental Test of Visual Motor Integration (VMI) for both a mildly retarded and normal IQ population of…

This study investigated the relationship between giftedness and conservation of weight based on Piaget's theory of intelligence. A total of 56 gifted and 72 nongifted children (ages 114-150 months) were tested on a series of tasks designed to measure conservation of weight. (MS)

Suggests that the general ability structure for retardates is more complex than the structure for normals, containing a "stimulus trace" factor in addition to verbal-educational and spatial-perceptual parameters. (RL)

This article emphasizes the importance of providing appropriate services to meet the needs of individual gifted students and the need to first diagnose the level of giftedness to administer the right "therapeutic dose." A chart is provided that defines levels of intellectual giftedness by IQ ranges and by prevalence. (Contains 5…

A study examined the impact of a gifted enrichment program on 80 Israeli students (grades 4-8) from disadvantaged neighborhoods. After program participation, girls' performance on an intelligence test was higher than boys'. While girls started out with slightly lower scores, they ended up with slightly higher scores than boys. (Contains…

This paper discusses research exploring the performance factors involved in studies which test for formal operations. It is suggested that several previous studies dealing with formal operations confound performance and competence in determining the extent of subjects' formal operations schemata. Factors which might account for performance…

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…

This three-part report discusses the concept of intelligence and its importance for educators. Part 1 considers the basic question of what intelligence is.
