Data from two samples of 32,862 and 6,757 males, respectively, from the Danish draft board indicate that gains in intelligence test scores are continuing and are concentrated among lower intelligence levels. Monte Carlo simulations suggested that this distributional change did not result from a ceiling effect in the test. (SLD)

The performance of 136 college students at the University of Western Ontario (Canada) on various parameters of two well-known puzzles was compared with performance on a measure of general intelligence and the Hidden Figures Test. An interpretation of the results is provided by Sternberg's experimental subtheory of intelligence. (SLD)

This commentary supports Linda Siegel's challenge to the learning disabilities field (in EC221505) to produce data indicating that dyslexic readers differ from other poor readers in their cognitive processing, educational prognosis, and response to treatment. The commentary also points out that the existence of Matthew effects reinforces Siegel's…

Howard Gardner's Multiple Intelligence construct is considered from the perspective of its viability in gifted education, especially in comparison with the more traditional Intelligence Quotient-based construct of intelligence. Empirical and theoretical support and contradictory findings are discussed from the literature in cognitive science and…

Examined relationships between American College Testing Program (ACT) academic test and Peabody Picture Vocabulary Test-Revised (PPVT-R), Wechsler Adult Intelligence Scale-Revised (WAIS-R), and 1986 Stanford-Binet Intelligence Scale: Fourth Edition (Binet IV). Thirty college students for whom ACT scores were available took other tests. Concluded…

Reviews investigations of McCarthy Scales of Children's Abilities as applicable to Puerto Rican and Mexican American children. Information too limited to draw conclusions regarding Puerto Rican applicability. Scales show promise as intelligence test for Mexican Americans. Recommends further research, especially among special education students.…

Forty-eight preschool-age children were administered the Kaufman Assessment Battery for Children-Nonverbal Scale and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) Performance Scale. Pearson product-moment correlations between the two scales ranged from .59 for a language-delayed group to .79 for the entire sample. Subjects…

A 76-item test of intellect-related personality traits was developed and administered to 46 gifted 13 year olds, 51 undergraduates, and 53 seventh and eighth graders. Three component-based traits were obtained: intellectual absorption, apathy, and pleasure. These traits were found to be related to intellectual performance. (TJH)

The stability of psychometric "g," the general factor of intelligence, is investigated in simulated correlation matrices and in typical empirical data from a large battery of mental tests. "G" is robust and almost invariant across methods of analysis. A reasonable strategy for estimating "g" is suggested. (SLD)

Three studies involving 16 college students explored cognitive processes reflected by reaction time (RT) and movement time (MT). The hypothesis that correlations of RT and MT with measures of intelligence are due to effects on a common stage of information processing cannot be rejected on the basis of study findings. (SLD)

Whether relations between intelligence test performance and information processing measures depend on individual differences in speed-accuracy preferences rather than capacity limitations and whether the impact of strategic variables changes with increasing age or extraversion was studied with 83 adults ages 50 to 79 years. Results are discussed…

Reliability of subtest composites corresponding to 46 abilities and influences presented by Kaufman (1979) was examined for the Wechsler Intelligence Scale for Children using standardization sample data (ages 6, 11, and 16). Increasing composite reliability was associated with the number of subtests and inclusion of Verbal Scale subtests in the…

As part of a neuropsychological assessment, 95 adult patients completed either standard or computerized versions of the Category Test. Subjects who completed the computerized version exhibited more errors than those who completed the standard version, suggesting that it may be more difficult. (SLD)

Three short forms of the Wechsler Adult Intelligence Scale-Revised (WAIS-R), developed in 1991, were cross-validated on 207 male and 133 female adolescent psychiatric inpatients and outpatients. Results show psychometric properties for the short forms that are comparable to those of the WAIS-R standardization sample. (SLD)

This study examined differences between Wechsler Intelligence Scale for Children-Third Edition (WISC-III) and Wechsler Intelligence Scale for Children-Revised (WISC-R) scores for 40 elementary students with learning disabilities. WISC-III Full Scale, Verbal, and Performance scores were lower than comparable WISC-R scores by one-third to one-half a…
