Discontinuation at ages five to six of dietary restriction in 14 children with classic phenylketonuria (PKU--a metabolic disorder which, if untreated, is associated with mental retardation) resulted in deterioration in intellectual function for some of the Ss. Deficits included visual motor integration and cognitive problem solving. (CL)

Examines age-related predictive relationships among an array of psychometric intellectual ability markers and text recall performance. Women from three age groups (ranging from 21 to 78 years) read and recalled four narratives at three delay intervals and completed a battery of intellectual ability tests. (Author/CB)

Compared the Wechsler Intelligence Scale for Children (Revised) (WISC-R) and the Leiter International Performance Scale with 40 average and above average students. Results indicated a curvilinear relationship between the WISC-R and the Leiter, which correlates higher at the mean and deviates as the Full Scale varies from the mean. (JAC)

Studies by the late English psychologist Cyril Burt of IQ scores of separated twins strongly suggested that intelligence was inherited. A summary of recent research costs doubt upon the validity of Burt's work. (SL)

A factorial design was used with two anxiety groups (high and low), three reinforcement conditions (praise, reproof, and praise plus reproof), and three levels of intelligence (high, middle, low). Subjects were 252 students (mean age, 14.7 years). (Author/JH)

Science education research, as well as science curriculum development, has concentrated on the intelligent student, to the unjustifiable neglect of average and below-average ability students. (AL)

To determine whether the idea is empirically supported that the majority of left-handers were intellectually inferior to right-handers, current research was examined. Inquiry indicated that the cognitive performance of left-handers was not significantly lower. (Author/CM)

Data are presented from families of monozygotic twin pairs which give evidence of genetic variance on the Block Design Test, a nonverbal measure of intelligence. Analyses of genetic and environmental effects on behavior are possible with this kind of information. (SA)

A response to Diane Hume George's "The Miltonic Ideal," which describes the evolution of consciousness and the involvement of women in academia. (DD)

Addresses selecting materials for children who have deficits or strengths in their use of certain learning modes based on Howard Gardner's seven types of intelligence: linguistic, musical, logical-mathematical, spatial, bodily-kinesthetic, and internal and external personal intelligence. Describes one picture book for each category. (Author/LRW)

This study, with 496 children seeking admission to a special program for gifted preschoolers, found that creativity (as measured by the Thinking Creatively in Action and Movement Scale) was significantly related to intelligence (as measured by standard IQ tests) when IQs were less than 120 but was not related at higher IQ levels. (DB)

General education classrooms are increasingly diverse as students with and without disabilities learn alongside one another. At each level, all students are learning to read and reading to learn standards-based content. A worry among some general and special educators who otherwise support the principles of inclusive education is what to do about…

This paper investigates the differentiation of cognitive abilities as a function of neuroticism. Specifically, we examine Eysenck and White's [Eysenck, H. J., and White, P. O. (1964). Personality and the measurement of intelligence. British Journal of Educational Psychology, 24, 197-201.] hypothesis that cognitive abilities are less differentiated…

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…
