This study, involving 64 students with specific learning disabilities, found positive correlations between the Wechsler Intelligence Scale for Children-III (WISC-III) and the Arithmetic subtest of the Wide Range Achievement Test-Revised (WRAT-R), the KeyMath-Revised, and the Peabody Picture Vocabulary Test-Revised, but not between the WISC-III and…

This study of 72 elementary children with learning disabilities explored how children maintain a positive self-concept despite academic difficulties. Children with high global self-concept, compared to low global self-concept, perceived themselves as more intelligent, more competent in nonacademic domains, and receiving more social support.…

The goal of this paper is to explore the ramifications of a nontraditional view of cognition and social interaction for the study of grammatical structure. (Contains 77 references.) (JL)

Discusses expert systems, intelligent computer-assisted instruction, and human-machine interface as they relate to business and education. (JOW)

It is argued that intelligent behavior cannot be understood without reference to inhibitory processes. A review of research findings suggests that resistance to interference and the capacity for inhibition are important sources of individual differences, associated with the operation of the frontal lobes of the brain.

Administered 1930s version of Pintner General Ability Tests: Verbal Series to 138 fifth grade students. Compared to scores from current intelligence and achievement tests, Pintner means were similar. Correlations of Pintner with other tests were of same order as those typically reported among contemporary measures. Item difficulty appeared similar…

Event-related potentials (ERPs) and reaction time (RT) were recorded concurrently during performance of 6 simple cognitive tasks by 30 right-handed women who varied in mental ability. Results suggest that ERPs and RT may assess stimulus evaluation time and the response-production time components of cognitive information processing. (Author/SLD)

Cranial capacities were calculated from external head measurements reported for a stratified random sample of 6,325 Army personnel measured in 1988. Data suggest that human populations differ in brain size by race and sex. The major source of variation in data was sex; race was second and rank last. (Author/SLD)

Two structural laws for intelligence tests are discussed: one law concerns the sign of correlation coefficients and gives conditions under which all correlations between test items will be positive; and one law concerns the relative sizes of the correlation coefficients between intelligence items. A cylindrical structure extends these laws. (SLD)

Measured aspects of problem solving in adult male psychiatric patients (n=9), who were hospitalized after attempted suicide. Controls (n=15) were patients with chronic idiopathic pain and healthy volunteers. Results indicated there were no differences in problem solving or flexibility, although suicidal patients scored significantly lower on…

Examined relationships among experimental tasks to measure planning, attention, simultaneous, and successive (PASS) cognitive processing following from Luria's theoretical model. Compared PASS model with null, memory-reasoning, verbal-nonverbal, and verbal-spatial-speed models. Results from students in grades K-2 (n=75) and 5-12 (n=132) indicated…

Examined factor structure of Wechsler Intelligence Scale for Children-Revised in 829 children and young adolescents with Full Scale Intelligence Quotients greater than or equal to 120. Most parsimonious interpretation of congruence analyses favored one-factor solution over two-factor solution conforming to verbal-performance dichotomy. One-factor…

Investigated most frequent types of examiner errors made by graduate students (n=26) in administering Wechsler Intelligence Scale for Children-Revised (WISC-R) and examined on which items these mistakes were most likely to occur. Findings identified deficiencies in traditional methods of teaching students how to administer the WISC-R. Students…

Presents a table that may be used to determine the probability of obtaining various Verbal Performance Scale discrepancies on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R). The table of differences is age referenced and should be used to determine the reliability of differences between Verbal and Performance Scale…

Responds to "Birth Order and Intelligence: Further Tests of the Confluence Model" by Robert D. Retherford and William H. Sewell. Reviews their arguments and suggests that their analyses of the Wisconsin Longitudinal Study data support rather than contradict the model. (CJS)
