The authors respond to a critique of their article proposing low IQ as the sole defining characteristics of mental retardation and address such issues as social versus intellectual definitions, the role of social adaptation in defining mental retardation, the relevance of diverse definitions to research and practice, and the nature-nurture…

Examined the relationships among two psychometric measures of nonverbal cognitive ability - The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Woodcock-Johnson Psychoeducational Battery-Tests of Cognitive Ability (WJPB-TCA) and a neuropsychological test of abstract reasoning and concept formation (Halstead Category Test) in 25…

Discusses the coming generation of supercomputers that will have the power to make elaborate "artificial realities" that facilitate user-computer communication. Illustrates these technological advancements with examples of the use of head-mounted monitors which are connected to position and orientation sensors, and gloves that track finger and…

Differences in performance IQs between deaf children of hearing parents (HP), deaf children of deaf parents (DP), and hearing children (HC) may be a result of differences in speed of information processing. DP adolescents were found to have faster reaction and movement times than HP or HC subjects along with equivalent IQs. (Author/VW)

Explores how well measures of verbal short-term memory and naming speed tasks predict children's reading achievement under various IQ control conditions. Both were effective, but when controlling for verbal IQ, memory measures are less reliable, whereas digit-naming speed remains a significant predictor of reading achievement. (MM)

Compared McCarthy Scale General Cognitive Index (GCI) and Stanford-Binet intelligence quotient (IQ) discrepancies for both normal and handicapped preschool children (N=10) of low socioeconomic status. Results yielded a significant positive relationship between GCI and IQ, as well as a significant discrepancy between the two scores, favoring IQ, of…

This literature review discusses the differences between individual and individualized instruction and explores ways of leading future computer assisted instruction (CAI) toward genuine individualized instruction. The development and design of intelligent CAI are described, and topics for future studies are suggested. (LRW)

The efficacy of Raven's Matrices in the gifted identification process is reviewed, focusing on their reliability, validity, and fairness and comparing them with other intelligence tests. It is concluded that, despite problems with narrowness of scope and standardization practices, these tests provide a useful screening device for intellectually…

A cross-racial comparison of the Wechsler Adult Intelligence Scale (WAIS) was made with the revised version, the WAIS-R. Three groups of Anglo, Black, and Mexican-American male college students were administered both versions of the WAIS on the same day. Significant differences were found among the racial groups.

Feuerstein's mediated learning theory was applied to a deaf population for investigating the cognitive modifiability of this population. The learning Potential Assessment Device (LPAD) was employed for determining transfer of learning along cognitive and behavioral dimensions. Results showed that the groups who received examiner mediation…

Studies in intellectual development, brain organization, and learning are summarized. They show that neither intelligence nor giftedness are solely the result of cognitive functions. Both rely on the use of the total brain in an appropriate environment. Intelligence is dynamic. It must be used and developed or it will be lost. (PS)

Demographic data, IQ, achievement, perceptual-motor, behavior ratings, and diagnostic classification (learning, mental, emotional disability or no handicap) were analyzed for all children (N=2002) referred for complete psychological evaluation during one school year in Iowa. Learning disabled children showed a distinct pattern different from…

Two groups of boys and their parents were given five divergent thinking tests as one part of a longitudinal investigation on exceptional giftedness in early adolescence. Canonical and bivariate analyses indicated that there was a strong correlation between the adolescents' divergent thinking test scores and their parents' scores. (Author/LMO)

The GEON-Project (1973-80) was a teacher-oriented program to improve kindergarten education in certain Dutch schools. Teachers were trained in diagnostic and differentiated teaching methods to improve students' emotional and cognitive development. The summative program evaluation found improvement in intelligence test results, but student school…

Discrepancies between the K-ABC and its theoretical base of simultaneous and sequential mental processing; technical and design problems related to disproportionate subtest contributions of the Simultaneous Scale to the Mental Processing Composite; the method of subtest-specific variance computation and use in interpretation; and utility with…
