Abstract
Developmental researchers have demonstrated the potent role of a knowledge base on children's memory performance. However, the only studies to experimentally assess a causal connection between children's knowledge and memory have failed to find such connection (DeMarie-Dreblow, 1991; Muir-Broaddus, Rorer, Branden, & George, 1995). In this study, we extended the length of training relative to earlier studies with samples of first- and seventh-grade children, incorporating knowledge training into their school curriculum. Both groups of children displayed an increase in knowledge as a result of training and corresponding significant improvements in recall, consistent with a causal relation between knowledge and memory. Although we believe that some of the benefits for the older children were associated with improvements in strategic organization, most of the gains, for both the older and younger children, could be attributed to item-specific effects of knowledge on recall.
