Examined, over 1 year, relations between information processing efficiency, working memory, and problem solving in sample of 8-, 10-, 12-, and 14-year-olds. Identified three-stratus hierarchy with individual dimensions organized in three constructs: processing efficiency, working memory, and problem solving. Found that individual dimensions were…

Used a microgenetic method to examine knowledge acquisition as a process by coordinating existing theories with new evidence. Subjects were 17 community college students (ages 22-47) and 15 fourth graders. Assessed knowledge acquisition in problem solving in both physical and social domains. Found multiple strategies for, and varying levels of,…

Maintains that Demetriou and his colleagues' project shows how developmental scientists can assess concepts from multiple frameworks and relate them through explicit modeling and targeted research to build explanations powerfully grounded in data and theory. Presents doubts related to specific conclusions because of issues related to the design of…

Investigated the hypothesis that impulsive children differ from reflective children in their preferred strategy of information processing, based on extent of stimulus analysis. The experiments employed third, fourth and sixth graders and a variety of tasks including matching, grouping, recall, and concept attainment. (MS)

This monograph describes the development of the Metaphoric Triads Task (MTT), an instrument designed to assess metaphoric comprehension. Validity and reliability of the instrument are discussed and data for 12 samples of subjects are reported. Sex differences were negligible, but progressive improvement in MTT score with age was noted. Pictorial…
