Three studies of college students found a sex difference in the correlation of memory scanning rate, short- and long-term components of free recall, and word recognition with memory span. Findings are discussed in terms of prior work and a theory presented to account for the obtained sex differences. (Author/RD)

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…

The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

Fifty-six children (ages 43 to 83 months) participated in an event conducted by two undergraduates dressed as clowns. Ten days later, interviews found metamemory ability, intellectual functioning, and temperament were helpful in determining a child's capacity to accurately recall information, although for the most part age was the best predictor.…

Retarded and nonretarded persons were compared on a task designed to preclude the use of cognitive strategies. Results suggest the possible importance of automatic processing deficiencies and invite a reconsideration of the idea that the relationship between intelligence and memory is due entirely to effortful processes.

In a study of the relationship between speed of information processing and general intelligence, vocational college students (50 black males and 56 white males) took eight different reaction time tests measuring the speed with which individuals perform various elementary cognitive processes, and a group test of scholastic aptitude (the Armed…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

The cognitive determinants of number analogy performance were studied by systematically manipulating the processing demands imposed by the items. To explore sources of developmental differences in analogical reasoning, subjects were included from two age levels, grades 4 and 5 and college. To allow the investigation of individual differences in…
