DOES IMMEDIATE IMITATION INFLUENCE LONG-TERM-MEMORY FOR OBSERVED ACTIONS

Long-term memory for object-related information acquired observationally was studied among younger and older toddlers under two conditions of acquisition and retention: direct imitation followed by reproduction after a 10 min delay (delayed imitation), and deferred imitation. A principal aim was to determine whether direct imitation fosters a form of enactive representation that improves long-term memory, or whether such memory is influenced more by visual encoding factors. Tasks consisted of five simple action combinations or separations. Results indicated that post-test scores were higher under all three post-test conditions than under pretest. Likewise, post-test performance was higher than that of a comparison group that did not observe the target actions. The results overall indicate that direct imitation did not operate substantially to improve memory for the modelled acts. Children were able to encode and retain about as much from their visual pickup of the modeled acts as from feedback obtained through the process of imitation. This finding was especially true for the older children. © 1991.
