Results are reported of an analysis of Wechsler IQ scores of 37 children (ages 3-14) with Asperger syndrome. Data revealed cognitive patterns dissimilar to those of children with other autism related disorders and similar to many typically developing and achieving individuals.. Findings are discussed in reference to identification and intervention…

Lynn [Lynn, R., 2002. Sex differences on the progressive matrices among 15-16 year olds: some data from South Africa. "Personality and Individual Differences 33," 669-673.] proposed that biologically based developmental sex differences produce different IQ trajectories across childhood and adolescence. To test this theory we analyzed the…

Item responses of two samples each of 622 normal and 573 educable mentally retarded children, 6 to 15 years of age, on Raven's Colored Progressive Matrices were submitted to a principal components analysis and varimax rotation. The following four factors were obtained: continuity and reconstruction of simple and complex structures, discrete…

Eleven studies made between 1958 and 1960 gathered information about the conditions under which children seek out television and under which TV has an effect on them. This book describes these studies and reports and interprets their results. In the first few chapters, some of the changes TV has made in the child's world are described, and…

This report discusses the outcomes of a study that examined 216 comparably aged children and adolescents (ages 2-18) with fragile X or autism to determine whether longitudinal change in cognitive ability and adaptive behavior was similar in the two groups. Results found decreases in Intelligence Quotient scores in young children with fragile X as…

This paper updates the discussion of Francoys Gagne's Differentiated Model of Giftedness and Talent (DMGT), which proposes a clear distinction between these two most basic concepts in the field of gifted education. Under the DMGT model, giftedness is defined as the possession and use of untrained and spontaneously expressed superior natural…

The discrepancy between middle-class and lower-class children's performance on IQ tests has been thought of as "cognitive deficit" or as "cognitive differences." This paper proposes another explanation--cognitive lag hypothesis--according to which the low IQ test scores of lower-class children are seen as due to the developmentally delayed…

Although the Wechsler Intelligence Scale for Children-Revised (WISC-R) involves modifications and a complete restandardization, the literature suggests that it remains very similar in nature to its predecessor, the Wechsler Intelligence Scale for Children (WISC). Individuals perform on the WISC-R largely the same as they do on the WISC. (Author)

Examined 128 children for contributions of biomedical risk conditions, SES, and HOME scores to prediction of intelligence, and association of extreme scores on HOME and SES to intelligence-test performance. Found home environment was the most important predictor of intelligence at all ages, with SES showing a smaller effect beginning at age 5.…

Argues against the presence of dysgenic trends for IQ on the basis of absence of change in the differences between various groups. Illustrates this with an example of the numbers of children born to Black and to White women at different educational levels. Discusses the effects, mechanisms, and implications of dysgenesis for IQ. (MMU)

Forty children (ages 7-11) referred for evaluation of learning problems, who had normal scores on measures of academic achievement, were compared to 81 similarly referred children who had scored low. Children with normal achievement scores had higher IQs and better decoding skills, however, the two groups showed similar neuropsychological…

Maternal attitudes and behaviors that result in infantilization and thus deter a retarded child from attaining potential were examined in 52 mothers and their borderline or mildly retarded children, 7- to 12-years of age, who had been tested previously. (Author/MC)

To learn if differences in age, intelligence, and sex account for differences in children's recall of TV commercials and in the degree of insistence with which they request that the advertised product be purchased, 54 gifted, 71 normal, and 53 educable mentally retarded children of both sexes were questioned after viewing commercials for breakfast…

To learn if differences in age, intelligence, and sex account for differences in children's memory of TV commercials and "degree of insistence" (DI) after viewing them, 54 gifted, 71 normal, and 53 educable mentally retarded children (of both sexes, 7-13 years) were questioned. The mediating influence of the three independent variables on DI was…
