Investigated adult age differences in accessing and retrieving information from long-term memory. Results showed that older adults (N=26) were slower than younger adults (N=35) at feature extraction, lexical access, and accessing category information. The age deficit was proportionally greater when retrieval of category information was required.…

Four hundred subjects 8 to 11 years old were given a modification of the Weigl Color Form Sorting Test in an attempt to assess the influence of chronological age, mental age, intelligence, and vocabulary level on the ability to utilize various numbers and different kinds of criteria of classification.

Examines the relative effectiveness of organizational strategy use at study versus test in a single-trial, free-recall learning task among 90 subjects drawn from second grade, sixth grade, and college levels. Developmental increases in performance were observed for the dependent measures of correct recall, study-trial organization, test-trial…

Human performance on verbal and spatial matching tasks was assessed every 15 minutes for eight hours. Significant 90- to 100-minute oscillations were observed for each task. It was also found that increases in performance on one task are accompanied by decreases on the other. (HM)

An examination was made of factors affecting reading performance of upper elementary students. Factors included effects of questions placed at various positions in the text, role of factual and inferential questions used as adjunct aids, and differences in processing strategies used by the readers in probed recall tasks.

Studied modeling individual latent growth curves of older adults on measures of fluid intelligence by fitting second-order polynomial curves reflecting initial test performance improvement followed by relative stability/drop to the recorded scores of each of 248 subjects. Results suggest substantial plasticity in fluid intelligence of older…

Two experiments investigated whether preschoolers attend to appearance instead of taxonomic relations in sorting sets of objects with conflicting appearances and taxonomic relations. Found that training and instructions have a significant effect on children's preference for sorting according to taxonomic relations or appearance, and that both…

Examined relationships between kindergarten children's acquisition of metacognitive knowledge related to mathematics, subjects' general ability, and the role of metacognition and ability in facilitating word problem solutions. Found that subjects acquired a substantial metacognitive knowledge about mathematical word problems, which correlated…
