Correlations between elementary sensory tasks and IQ scores support Galtonian theories of intelligence, which emphasize speed of signal encoding and transmission in the nervous system. Research involving 73 male Navy recruits indicates that such theories are warranted only when elementary tasks are viewed separately. Task complexity in…

Navy recruits (n=243) participated in an examination of the relationship between strategy use and intelligence through paper-and-pencil and computer-administered tests that considered reaction time. Overall, results weaken arguments that strategy use is related to general intelligence and that strategy use is a robust, traitlike construct. (SLD)

Five major trends in the study of intellectual abilities are identified. These suggest that in the future several kinds of tests will be used to measure several kinds of basic processes of intelligence. There will be a corresponding decrease in concern to measure a single attribute of general intelligence. (Author/RD)

The genetic relationship between intelligence and components of cognition remains controversial. Conflicting results may be a function of the limited number of methods used in experimental evaluation. The current study is the first to use CANTAB (The Cambridge Neuropsychological Test Automated Battery). This is a battery of validated computerised…

Several measures of the speed of information processing were related to ability factors derived from the Cattell-Horn theory of fluid and crystallized intelligence. Correlations among the ability measures, among the information processing measures, and between the two domains were analyzed using confirmatory factor analysis. (Author/PN)
