In 2 studies, the authors examined the development of the relationship between inductive reasoning and visual recognition memory. In both studies, 5- to 6-year-old children and adults were shown instances of a basic-level category (dogs) followed by a test set containing old and new category members that varied in their similarity to study items.…

Discussed theories relating forgetting rates and age. Developed a theory and mathematical model for examining storage failure versus retrieval failure, true forgetting versus test-induced processes, and storage- versus retrieval-based reminiscence. A series of experiments studied these factors in children and seniors. (BC)

Replies to Guttentag's commentary on Brainerd and others' research on forgetting. Discusses measurement of forgetting, differentiation of storage from retrieval factors, and ramifications of findings for strategic or process theories of memory development. Considers the role of research on forgetting in child development research. (BC)

This study examined effects of individual differences in speak-span scores and variations in memory demands on class-inclusion performance of 10-, 13-, and 15-year-olds. Results from regression analyses and the mathematical model indicated that differences in age, speak span, and memory load affected performance. Effects of speak span and memory…
