A reevaluation of a number of experiments suggests that normal and retarded persons differ on short-term memory tasks from the time of initial stimulus exposure. The hypothesis that memory differences are due to differential encoding as a result of more adequate rehearsal by the normal subjects is unacceptable. (Author/BW)

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)

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…

A directed forgetting task was used in an investigation of the conditions under which normal and educable mentally retarded junior high school students would disregard irrelevant information. Results showed that irrelevant information in memory interfered with the performance of only the retarded group, when given a minimal explanation of the…

Asian-American, White, and Black Children in grades 2-6 were tested for intelligence, achievement, and short-term memory. Factor analysis yielded two main factors: memory and general intelligence. The three groups differed distinctly at every grade level. Achievement correlated more with memory than with general intelligence. (Author/CP)

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.

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…
