Recent research has shown that certain stimuli are better remembered 6 months after initial exposure than after one week. An alternative explanation of these findings was tested. The explanation posited that the younger children "remember" as well at one week as 6 months later, but at the earlier testing many do not realize what aspect of the stimulus the experimenter wishes reproduced. Findings indicated that pre-training to insure that subjects understood relevant stimulus attributes did not improve one-week or 6-months performance.
