This investigation tracked changes in categorical bias (i.e., placing objects belonging to the same spatial group closer together than they really are) while 7-, 9-, and 11-year-olds and adults were learning a set of locations. Participants learned the locations of 20 objects marked by dots on the floor of an open square box divided into…

Two experiments investigated extent to which English- and German-speaking childrens' mental arithmetic was constrained by working memory. Found higher mental addition spans when numbers were visible throughout calculation than when not. Variation in addition span with age and arithmetical operation difficulty approximated to a linear function of…

Investigated the specificity of reading-disabled children's deficits in working memory capacity. Found that reading-disabled 10-year-olds performed worse than normal-reading children, matched for chronological age and reading age, on all measures of working memory capacity. Their poorer performance seemed to be due to a general lack of capacity…

The short-term recall of word-triads was tested, comparing retention over three types of intervals within 24 preschoolers. Results suggest that the condition effect in short-term recall did not disrupt the long-term storage of the items. (Author/CS)

Assessed the influence of mnemonic and attentional aids on children's double-alternation learning, in a prediction situation in which subject had to learn to produce two consecutive responses of the alternate types. (Author/AJ)

Four experiments examined effects of the number of features and feature relations on learning and long-term memory in 3-month olds. Findings suggested that memory load size selectively constrained infants' long-term memory for relational information, suggesting that in infants, features and relations are psychologically distinct and that memory…

Twelve moderately retarded children were trained on 2-choice visual discrimination problems with interpolation of another item between training and retention tests. Results indicated that well-learned items are rehearsed less. (SBT)

Ten boys and 10 girls ages 29-35 months, were tested individually on a memory task requiring free recall of two-item lists. No sex differences in response were noted. The mean number of correct responses and the mean number of correct pairs were higher for related items, and, in addition, the children frequently reported the last object they saw…

A paired-associate task relational or non-relational visual and linguistic stimuli was presented to kindergarten and fifth-grade students. Results indicated that a relationship in both modes facilitated recall better than a relationship in only one mode, and that a relationship in either mode was better for recall than none at all. (DP)

The effectiveness of three fading and two nonfading procedures were compared in training kindergarten children on an oddity problem in which shape was the relevant dimension. (SBT)

Skilled and unskilled readers from grades 3, 5, and 7 performed one of three memory tasks on a randomized list of primary word associates. Examined reading skill differences in relation to memory skills. (BD)

Fifth graders were asked to learn 32 syntactically varied semantically unrelated sentences containing combinations of agentive, objective, and instrumental case relations. Results were discussed in terms of ways to store sentences. (ST)

This study examined those characteristics of a sequence to which children respond when they are presented with partially learnable sequences followed by a series of trials on which all responses are correct. (Author/RK)
