The main purpose of this investigation was to study the impact of kindergarten upon the IQ test performance of young children. Results indicate that kindergarten experience has a positive influence upon test performance. (Author)

Based on the author's PhD dissertation (University of California, Los Angeles).

Summarizes Arthur Jensen's theories on IQ, heritability, and Black intelligence and reviews some responses to Jensen. (JLF)

Evaluated the ability of the Wonderlic Personnel Test to replicate the Wechsler Adult Intelligence Scale (WAIS) with (N=120) normal persons divided into principal and cross-validation groups. Correlations between the Wonderlic IQs and the WAIS Full Scale IQs were .93 for the main group and .91 for the cross-validation group. (Author)

The major impediment to an understanding of human intelligence is the fragmented way it is studied. An orientation is suggested which integrates various aspects of the study of human intelligence. If this approach is adopted, intelligence tests will be an integral part of a systematic theory of knowledge acquisition. (Author/RD)

P. Schonemann (1992) claimed that the positive correlation predicted by Spearman's hypothesis of the positive relationship between the standardized black-white differences in means on cognitive tests and loading of the tests on general cognitive ability was ascribable to a statistical artifact. This paper refutes that claim. (SLD)

Used computer simulation to examine the reliability of interpretations for Kaufman's "intelligent testing" approach to the Wechsler Intelligence Scale for Children (3rd ed.) (WISC-III). Findings indicate that factor index-score differences and other measures could not be interpreted with confidence. Argues that limitations of IQ testing…

The purpose of this article is to disclose and comment upon some of the conceptual and empirical confusions that confront a revised concept of intelligence which sees intelligence as general skill(s) that can be directly taught rather than as a relatively fixed ability. Implications for teaching thinking skills are discussed. (IAH)

The test-retest reliability and predictive validity of developmental quotients (DQs) derived from the Cattell Infant Intelligence Scale was assessed with 83 children with mental retardation, age 30 months or more. Scores were impressively stable on retest. DQs derived from the Bayley Scales of Infant Development were superior to Cattell DQs in…

The retest stability of four Wechsler Adult Intelligence Scale-Revised (WAIS-R) short forms (Kaufman, Ishikuma, and Kaufman-Packer; Reynolds, Wilson and Clark; Silverstein; Ward) was investigated with 61 subjects aged 75 to 87 years. Short form stability in each instance was comparable to that of the standard WAIS-R. (SLD)

Aspects of intellectual function were investigated in a school age sample of 17 Fragile X individuals, employing the Wechsler Intelligence Scale for Children (Revised). The general ability of the sample was substantially below normative average because of the significantly poorer performance by males than females. (Author/DB)

Eight-seven adult outpatients in Edinburgh (Scotland) were tested with the Wechsler Adult Intelligence Scale--Revised (WAIS-R) and a test of visual inspection time (IT). Factor analysis confirms that IT correlates more strongly with performance than with verbal intelligence quotient (IQ) scores. Implications for the study of IT and mental tests…

The study investigated gender differences in resting EEG (in three individually determined narrow [alpha] frequency bands) related to the level of general and emotional intelligence. Brain activity of males decreased with the level of general intelligence, whereas an opposite pattern of brain activity was observed in females. This difference was…

School psychologists in North America are facing a transformation of their professional practices brought about by impending changes in operational definitions of learning disabilities (LD). This multimethod study explores the learning disabilities-related beliefs and practices of school psychologists in Western Australia, where these changes have…
