Very close age spacing was an obstacle to high academic performance for later borns. In family relations and self-esteem, first borns scored better and performed in school as well as their potentially much more able younger siblings, regardless of age spacing. (Author)

This article reviews sex studies of children of cousin marriages and three studies of children of incestuous matings. It is argued that these studies, taken as a whole, provide no substantial evidence for an inbreeding depression effect within the polygenic system commonly asserted to determine IQ. (Author/DB)

Performance differences between 10 nonretarded children and 10 moderately/severely retarded adolescents on a manual control task were examined. Results suggested that the ability to discriminate internal cues is related to IQ differences. (Author)

The literature reveals a marked decline in performance on the Visual Reproduction subtest with increasing age. Both level of education and intelligence seemed to exert a substantial influence on performance which may be significant in clinical evaluations. (Author)

The Revised Wechsler Intelligence Scale for Children appears significantly to widen the gap between Black and White performance, increasing the likelihood of unjustified negative social and educational consequences. (Author/EB)

Analysis of correlations between Verbal and Full Scale IQ scores for 231 high-IQ psychiatric outpatients indicated that Verbal IQ appears partially valid as a WAIS short form for this higher IQ group. Results are interpreted in terms of Resnick and Entin's short form validity criteria. (Editor/SJL)

Groups of middle-aged and elderly men and women were compared on three problem solving tasks, including written problems, the 20-questions procedure, and problems administered on a Heuristic Evaluation Problem Programmer. (MS)

Anglos achieved higher scores in academic achievement, IQ, and occupational aspiration than did Navaho students; Anglo students who achieved higher scores had more positive views of the average Indian than Anglos with lower scores; Navaho stereotypes of Anglos were not related to achievement and intelligence level.

This study involving 30 college students with learning disabilities and 30 students without learning disabilities (ages 18-30) compared results obtained on the Wechsler Adult Intelligence Scale-Revised and the Kaufman Adolescent and Adult Intelligence Test. Results found no significant differences between the two groups or between tests.…

A study involving 106 gifted children and 71 typical children (ages 6-9) evaluated the correlation between intelligence and performance on the Test of Variables of Attention (T.O.V.A). Results found gifted children with ADHD performed better on tasks of omission error, commission error, and response sensitivity than typical children with ADHD.…

This article illustrates the use of confirmatory factor analysis (CFA) to explicate constructs underlying performance assessment tasks based on Gardner's (1993) theory of multiple intelligences. Data from Plucker, Callahan, and Tomchin (1996) were reanalyzed using CFA. A model with three factors that combined linguistic and interpersonal…

Criticizes claims in "The Bell Curve" that a high value for heritability of intelligence constrains the extent to which environmental changes can increase intelligence. Cites adoption studies and the increasing intelligence of successive cohorts of U.S. children as evidence that intelligence can increase substantially without heroic…

Criticizes Herrnstein and Murray for their lack of respect for the truth, displayed throughout "The Bell Curve"; their willingness to encourage disharmony between groups they identify as cognitively different and to foment fear and distrust of an alleged underclass portrayed as dangerous and beyond help; and their lack of interest in…

Reported the regrets of intellectually gifted subjects to determine if the nature of their regrets mirrored those reported by the general population. Analysis of survey responses of subjects (mean age=74) revealed that, like the population as a whole, they harbored more regrets of inaction than regrets of action. (RJM)

Robert J. Sternberg's research on cognitive style and model of "mental self-government" at all educational levels have led to a pilot elementary/secondary curriculum to help students develop common sense and practical judgment as well as intellect. The interinstitutional effort between Yale and Harvard universities includes Howard…
