To test general and specific processes of symbol learning, 4- and 5-year-old children learned three kinds of abstract associates for novel objects: words, facts, and pictograms. To test fast mapping (i.e., one-trial learning) and subsequent learning, comprehension was tested after each of four exposures. Production was also tested, as was…

Results of four experiments show that developmental differences in elaborative conceptual processing at acquisition and retrieval contribute independently to developmental increases in recall. Item identification processes for both words and pictures constrain children's elaborative processing. The constraints are time limited. (RH)
