Two experiments examined whether correlations between IQ and probed serial running memory depend on IQ-related individual differences in the retention of order information in short-term memory. Children's IQ correlated with memory, regardless of whether instructions emphasized serial or free recall; and with recent item but not recent order…

The relationship between psychometric intelligence and rapid acoustic information processing was explored in two experiments using college students. Group differences occurred in threshold interstimulus intervals required for recognition and in speed. Results were interpreted as indicating better information processing efficiency (higher…

Recent studies are examined for methodological adequacy in establishing dimensions of individual differences in information-processing abilities, and the theoretical problems involved in inferring psychological processes from individual difference dimensions. Methodological inadequacies include use of small samples, questionable procedures in…

An approach to intelligence which emphasizes domain-specific constraints on knowledge structures is compared to information processing approaches. The evaluation of any cognitive ability as being intelligent crucially depends on prior specification of the formal constraints on the domains of knowledge from which that ability originates.

In studies of the relationship between masculinity-femininity and intelligence, data should be analyzed using correlational analysis for the complete distribution, rather than analysis of variance of extreme groups. The earlier work of Baucom and Welsh (EJ 171 822) was used as illustration. (BW)

Humphreys' criticisms (TM 503 269) of the work of Welsh and Baucom (EJ 171 822) are inappropriate since his findings are based upon a different measure of masculinity-femininity and a population which is somewhat different. Also, his insistence on correlational analysis to the exclusion of extreme group design is viewed as inappropriately…

Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…

Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…
