Meta analysis is used to examine the results of 189 studies concerning sex and intelligence. The relationship between these two variables is investigated for five large clusters of cultures. For some intelligence factors, significant cultural differences are found between Western groups and Asian/African groups. (VM)

Compared the performance of 56 children on the 11 subscales of the Luria-Nebraska Neuropsychological Battery-Children's Revision. Results revealed significant differences on Receptive Speech and Expressive Language subscales, suggesting a possible differential sensitivity of the children's Luria-Nebraska to verbal and nonverbal cognitive deficits.…

Examines the contiguity of siblings within family structure--a concept reflecting how much of the family environment siblings share with one another--in relation to within family IQ scores. Results fail to demonstrate family structure effects. (HOD)

Performance on the Wechsler Intelligence Scale for Children-Revised was compared for reflective and impulsive children, aged 8-11. Reflective children scored higher on the attention-concentration and visual organization subtests. There were no significant differences in verbal comprehension. (Author/GDC)

Results showed gross differences between low and average IQ Ss on a number of variables. The regression results, however, indicated that the determinants of career attainment had similar effects among low and average IQ Ss, and that status attainment theory applied equally well to the two groups. (Author/DLS)

Results indicated that retarded Ss, relative to normal Ss of all ages, responded particularly slowly to static property statements when objects were animate, and to intrinsic-action properties when objects were inanimate. (Author/DLS)

The study compared the problem solving strategies of intellectually gifted (N=133), average (N=102) and mentally retarded (N=51) children on two-dimensional integration problems. Gifted children tended to integrate dimensional information by addition, average children used lexicographic strategies, and retarded children relied on a single…

Comparison of the mental status of 30 subjects with Down's Syndrome mosaicism and 30 matched subjects with trisomy 21 Down's Syndrome found that the mean intelligent quotient of the mosaic Down's Syndrome group was significantly higher and that this group showed better verbal abilities and more normal visual-perceptual skills. (Author/DB)

To assess the effects of individual attentional focus differences on measures of mental skills, distractibility was studied for 272 first- and second-year college undergraduates through a speeded visual search task and tests of mental and verbal ability. Results suggest that perceptual/attentional factors are an important aspect of measured…

A protocol for screening the complex verbal, simple verbal, simple visual, and spatial working memory was tested on 125 persons with mild, moderate, and severe mental retardation. Results found the test discriminated well between levels of mental retardation, correlated reasonably well with IQ, and possessed relatively good test-retest…

The vocabulary and block design short forms of the Wechsler Intelligence Scale for Children-Third Edition were administered to 63 children with attention deficit hyperactivity disorder (ADHD), 69 children with reading difficulties (RD), and 68 children with comorbid ADHD and RD. No significant differences were found. (Contains references.)…

The study examined the intellectual performance of 248 school age students 157 of whom were taken from public school settings. Of these, 93 were emotionally handicapped (EH) students and 64 were regular education students. The remaining subjects came from a residential school for EH children and youth (n=15) and from a summer program for…

To clarify the effects of noise, sex, and intelligence on student performance, 289 sixth-grade students were randomly assigned either the Standard Progressive Matrices (SPM) or the STEP Reading Test Form 3 (STEP III) to be taken under high- or low-noise classroom conditions, with gender and intelligence as variables. Students who took the SPM…

Comparison of goals (number and content) in individual program plans for developmentally-disabled persons in New York (N=170), Pennsylvania (N=298), and Tennessee (N=1,275) indicated that goals varied as a function of intellectual level in all three states and as a function of program setting (institutional, community, or residential) in New York.…

Investigation of the role of intellectual giftedness in influencing parents' perceptions and mediation of gifted (N=364) and non-gifted (N=386) fourth-graders' television viewing revealed that all parents exercised modest levels of intervention. However, students' intellectual giftedness did influence parents' perceptions of the possible impact of…
