Developmental differences in reasoning ability and item processing demands are analyzed in a study of cognitive determinants of number analogy performance in two IQ levels of elementary school children and college students. The amount of solution-related information in working memory was the crucial processing demand. Process differentiations of…

Children referred for psychological evaluations of completed the Bender-Gestalt and then reproduced designs from memory. Numbers of designs recalled increased with age and Performance Intelligence Quotient. The importance of developmental level in evaluation and establishment of cut-off recall scores for designs were discussed. (Author/RD)

While for 31 trainable mentally handicapped children and for 31 nonhandicapped, there were no differences in static balance on left or right legs, total balance time was significantly different between the two groups. This confirms prior work which related motor proficiency to intelligence. (Author/RD)

Zajonc and Bargh's (EJ 241 537) application of the confluence model to six national data sets is critiqued. Extreme differences in intelligence levels are predicted between nations, including substantial retardation for some populations. Moreover, the parameter values used do not allow mental growth functions which are consistent with previous…

Recent studies are quoted as indicating that Japanese students are superior to American students in actual achievement in mathematics, but there is conflicting evidence as to whether the Japanese are intellectually superior. Several possible reasons for Japanese superiority are suggested, and a need for improvement in America is noted. (MP)

In this response to the critiques by Jensen and McVicker Hunt, we focus on the meaning of g, the permanence of effects produced by early education, and the educational significance of IQ gains produced by early education programs. New longitudinal data from our study presented. (Author/RD)

Using Locus of Control in Three Achievement Domains (LOCITAD), this study examines differences in locus of control orientation for 80 Anglo, 80 Black, and 44 Chicano high school students with respect to success and failure in three domains--intellectual, social, and physical. (Author/MP)

Administered the Raven Progressive Matrices (RPM) to (N=408) individuals in 100 family groups. Scores on all five subtests were highest in the 18-26 age group, decreasing with age. Males scored higher on each subtest in each age group. Performance on the RPM increased with additional years of education. (Author)

An experiment was designed to find out whether there were any quantitative and qualitative differences in the spoken discourse of 'high' and 'low' ability 16-year-old pupils in discussions of problems arising from textual material. Cognitive, linguistic and quantitative analyses of the discourse were carried out. (Editor)

This paper is intended to aid interpretation of intelligence tests in light of neurological findings and to suggest future test designs which would reflect cerebral hemisphere specialization. The need is emphasized for improved measures of right brain functioning, especially for Blacks, who exhibit some degree of right hemisphere preference. (SJL)

Explanations of differences in IQs of Northern and Southern Blacks focus on selective migration (hereditarians) or environmental causes such as education, discrimination and cultural deprivation. In this paper the environmentalist position is questioned and certain neglected features of Lee's data are construed as providing strong evidence for…

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 study examines some relationships pertaining to socioeconomic status and cognitive ability patterns in fourth graders. Specifically, it explores the relative merits of Jensen's hierarchical theory of two levels of cognitive ability, in contrast to a process scheme, positing two parallel modes of coding information. (Editor/SJL)

This article examines psychometric analysis regarding the viability and limits of IQ testing in the context of "The Bell Curve." It discusses eyeball analysis versus item analysis, mean differences, validity coefficients, general intelligence, and IQ and gifted education, and urges a search for intrapersonal and environmental catalysts…
