Six hierarchical clustering methods were applied to subtest intercorrelations for each of the nine age groups in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) standardization sample. Results point to the possibility of three simultaneously plausible solutions as they support each of the traditional factor structures in varying degrees.…

The association of typical intellectual engagement with various abilities, and the association of such engagements with broader personality domain and available performance measures were studied with 138 undergraduate students (61 males and 77 females). Results demonstrate that individuals differ in typical intellectual engagement and that those…

Examined relationship between Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wide Range Achievement Test-Revised (WRAT-R) scores among 78 educable mentally retarded adolescents. Found that WAIS-R Verbal intelligence quotient (IQ) was significantly correlated with all WRAT-R subtests. Performance IQ was significantly related only to…

This study used citation analysis to determine whether the disciplines contributing to the journal literature of artificial intelligence (AI)--philosophy, psychology, linguistics, computer science, and engineering--share a common AI research base. The idea that AI consists of a completely interdisciplinary endeavor was refuted. (MES)

Examined concurrent validity between Woodcock-Johnson Psycho-Educational Battery-Revised Tests of Cognitive Ability (WJ-R, COG) (Early Development) and Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R) by administering instruments to 30 normal 3, 4, and 5 year olds. WJ-R Broad Cognitive Ability and WPPSI-R Full Scale IQ and…

Examination of the opinions of 160 people on social issues, and the evidence supporting their opinions, indicates that argumentative reasoning ability does not differ with sex or age but is strongly related to educational level. Informed dialogic argument may be a way of developing higher order thinking skills. (SK)

Examines the hypothesis that a poor educational system produces an increase in criminal behavior by reviewing and evaluating research evidence related to relationships such as intelligence and school achievement, school achievement and criminal behavior, and by relating research to data from the Georgia Department of Corrections.

This response to Stanovich (EC 607 092) considers the relationship between rationality and intelligence. It sees rationality as a relatively minor part of intelligence and proposes the concept of practical intelligence (or the lack thereof) as an alternative to Stanovich's concept of dysrationalia. (DB)

This paper responds to reactions to the proposal of a new learning disability, dysrationalia, by suggesting that alternative ideas of "practical intelligence" are equally inexact, that rationality must be defined broadly, and that epistemological relativism can be carried too far. (DB)

Provides a critical analysis of K. E. Stanovich's argument for the use of the concept of dysrationalia in educational research. It argues that the concept of dysrationalia must be better conceptualized and elaborated, encompass a theory, be operationalized, have convergent and discriminant validation, and have safeguards against misuse.

Vertex event-related potentials (ERPs) were obtained from undergraduates performing an inspection time task together with measures of inspection time (n=35) and mental ability (n=28). Techniques that reveal changes over time in the relationship between ERP measures and psychometric indices were presented. (SLD)

In a study involving 38 adult females, nerve conduction velocity (NCV) did not correlate with intelligence or reaction time. A reanalysis of the Vernon and Mori data showed a possible sex difference in relation to NCV and intelligence, with the correlation between these variables much smaller in females than males. (SLD)

The mental representations and processes used in verbal comprehension were studied in 2 preliminary studies and 2 experiments involving a total of 158 college students solving synonym or sentence completion tasks. Response choices and latencies could be predicted with explicit information-processing models. Implications for theories of…

Administered Stanford-Binet Intelligence Scale: Fourth Edition and Kaufman Assessment Battery for Children to 40 referred children. Correlation coefficients computed between two tests were strong, suggesting consistency in underlying global construct being measured; however, no compelling evidence supporting theoretical structure of two scales was…

A study of eight normal right-handed men demonstrates widespread significant decreases in brain glucose metabolic rate (GMR) following learning a complex computer task, a computer game. Correlations between magnitude of GMR change and intelligence scores are also demonstrated. (SLD)
