This paper summarizes empirical findings of research on a theory of general mental ability, based on laboratory studies of the relationship between measurements of individual differences on conventional psychometric tests and in speed and efficiency of information processes. The paper covers characteristics of "g" (general mental ability),…

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)

Applies Howard Gardner's theory of multiple intelligences (linguistic, logical-mathematical, spatial, musical, bodily kinesthetic, interpersonal, and intrapersonal) to designing time-telling exercises for young learners. The idea is to link instructional objectives to words, numbers or logic, pictures, music, the body, social interaction, or…

To assess the effects of individual attentional focus differences on measures of mental skills, distractibility was studied for 272 first- and second-year college undergraduates through a speeded visual search task and tests of mental and verbal ability. Results suggest that perceptual/attentional factors are an important aspect of measured…

The relationship between speed of information processing (SIP) and psychometric intelligence was investigated by giving 60 college students (22 males and 38 females) 2 choice reaction time (RT) tests (modified Hick paradigm) and Raven's Advanced Progressive Matrices. Results support an association between intelligence and SIP. (SLD)

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 six Holland-based Interest Scale scores yielded by the Harrington-O'Shea Career Decision-Making System (CDM) (T. Harrington and A. O'Shea, 1982) were related to sex, race, and performance on the Kaufman Adolescent and Adult Intelligence Test for 254 adolescents and young adults. CDM scores did not relate to most of the variables studied, and…

Analyzes intelligence tests as items of symbolic culture. Test takers often do not share the presuppositions about values, knowledge, and communication implicitly assumed by the test. Suggestions are offered to detect, correct, and avoid the cross-cultural misunderstandings that undermine the validity of such tests. (MMU)

Tested 101 adults, aged 77, who had completed psychometric intelligence testing in 1932, with the same test of mental ability. Results of this study, the longest follow-up study reported to date, show substantial stability in mental ability differences from childhood to late life. (SLD)

This article illustrates the usefulness of higher order factor analysis in demonstrating the presence of general intelligence as the factor underlying performance on 13 indicators of four identified multiple intelligences. Data are reanalyzed using maximum likelihood extraction with oblique rotation and indicate a general intelligence factor…

This article responds to a previous article that illustrated the usefulness of higher order factor analysis in demonstrating the presence of general intelligence as the factor underlying performance on 13 indicators of four identified multiple intelligences. Conceptual areas of difference and agreement are delineated. (Contains ten references.)…

This paper describes the development and empirical investigation of two new paper-and-pencil measures of elementary cognitive tasks (PP ECTs). In three empirical studies involving 333 adults, the PP ECTs proved reliable. They were substantially correlated with other measures of psychometric intelligence and they displayed convergent validity with…

Administered untimed Raven's Standard Progressive Matrices (SPM) to 173 African and 136 White college students in South Africa. In comparison with the 1993 U.S. normative sample, African students scored at the 14th percentile, and White students at the 61st percentile. Differences were greater on SPM items with the highest item total correlations,…

Debunks several myths that have arisen in schools' misapplication of the author's multiple intelligences (MI) theory. Argues that seven intelligences do not require seven different intelligence tests. An intelligence is a construct, not a domain, discipline, or learning style. MI theory is empirical and compatible with general intelligence theory.…

The vocabulary and block design short forms of the Wechsler Intelligence Scale for Children-Third Edition were administered to 63 children with attention deficit hyperactivity disorder (ADHD), 69 children with reading difficulties (RD), and 68 children with comorbid ADHD and RD. No significant differences were found. (Contains references.)…
