From the lab to the classroom: Improving children's prospective memory in a natural setting.

Abstract

Laboratory-based studies have shown that children's ability to remember intentions (i.e., prospective memory; PM) can be improved by asking them to imagine performing the PM task beforehand (i.e., episodic future thinking; EFT) or to predict their PM performance. Moreover, combining the two strategies resulted in an additional improvement in children's PM performance. However, the effectiveness of these encoding strategies on real-life PM tasks is still unknown. The aim of the present study was to evaluate the effect of EFT instructions, performance predictions, and of their combination on children's PM in a natural setting, namely in the classroom. Twelve classes composed by a total of 121 children (53% females) aged between seven and 9 years participated to the study. As a PM task, children were asked by their teachers to deliver a letter to their parents and to bring it back to school the next day. Children were divided into four groups: control, prediction, EFT, and the EFT + prediction group. Parent reports on children's everyday prospective and retrospective memory failures were also collected. Results showed that encoding strategies were effective in enhancing children's PM performance. However, differences compared to previous laboratory-based findings emerged since predicting PM performance resulted to be most effective in enhancing real-life PM performance. Moreover, parent reports were related to children's PM performance. These novel findings highlight the importance of studying PM interventions in natural settings in order to increase their ecological validity and inform educational practices.
