The Wechsler Preschool and Primary Scale of Intelligence, 4th ed. includes two measures of working memory normed on children 2;6-7;7. The present analyses of the typically developing children (N = 1,591, 812 female, 779 male, with an ethnic distribution approximating the United States) provide new, theoretically important information about these…

Working memory is the retention of a small amount of information in a readily accessible form. It facilitates planning, comprehension, reasoning, and problem solving. I examine the historical roots and conceptual development of the concept and the theoretical and practical implications of current debates about working memory mechanisms. Then, I…

According to some views of cognitive growth, the development of working memory capacity can account for increases in the complexity of cognition. It has been difficult to ascertain, though, that there actually is developmental growth in capacity that cannot be attributed to other developing factors. Here we assess the role of item familiarity. We…

Established the differential maturation of rapid-speaking durations and the durations of interword pauses in the memory-span-task responses of first, third and fifth graders. Found that a particular memory span is accompanied by different profiles of processing rates in children of different ages. (Author)

Notes that there has been far less mathematical modeling of children's memory than of adults' memory. Explores the flaw in fuzzy-trace model, and maintains that situations in which partial verbatim information is used along with partial gist information fall outside the boundary of this type of model. Suggests refining the concepts of and…

Verbal-to-spatial associations in working memory may index a core capacity for abstract information limited in the amount concurrently retained. However, what look like associative, abstract representations could instead reflect verbal and spatial codes held separately and then used in parallel. We investigated this issue in two experiments on…
