In the first two of three trials kindergarten children were required to recall items by category from presented 3-category or S-category list, and on the third trial they were instructed to make free recall. The results showed that on constrained to free recall trials, recall declined for the 8-category list more greatly than for the 3-category list, and that the facilitation effects of constrained recall were retained if cues of category were given on the third trial. These results suggest that by experiencing constrained recall kindergarten children would fail to retrieve higher categorized units, but not to retrieve the items within each categorized units.
