We present two studies that examined developmental differences in the implicit and explicit acquisition of category knowledge. College-attending adults consistently outperformed school-age children on two separate information-integration paradigms due to children's more frequent use of an explicit rule-based strategy. Accuracy rates were also…

Two approaches to development are identified--ecological and cognitive. A comparison of the two approaches is made, and decisions are made favoring the ecological approach. A detailed description of the advantages of the ecological approach is provided by means of a systems theory model. (Author/DB)

Describes phonological sensitivity at different grain sizes as a good predictor of reading acquisition in all languages. Presents information on development of phonological sensitivity for syllables, onsets, and rimes. Illustrates that phoneme-level skills develop fastest in children acquiring orthographically consistent languages with simple…
