Preschoolers retain more details from event sequences 1 week following an in-group demonstration

Abstract

Previous research highlights that the learning processes of preschool-aged children are influenced by the cultural group membership of the information sources. As of yet, however, no study has aimed to explore the influence of cultural group membership on the long-term retention of novel information. In the current study, 4-year-old children observed three event sequences that were demonstrated by either an adult speaking their native language or a foreign language speaker. In Experiment 1, children (N = 56) were allowed to imitate the events immediately. Results showed that the average number of accurately reproduced details (native = 3.26; foreign = 3.11) and the order of event elements (native = 1.69; foreign = 1.49) did not significantly differ in the two conditions. In Experiment 2, children (N = 56) were allowed to imitate only following a 1-week delay. In this case, children retained more details (native = 2.6; foreign = 2.2) and reproduced the order in the event sequences more accurately (native = 1.18; foreign = 0.87) following a native demonstration. The behavior of children in all conditions differed from a baseline group without any instruction (n = 15). These findings show that preschoolers retain more information in the long term when it was demonstrated to them by a member of their own culture. Importantly, they also learn from people belonging to different cultures—as evidenced by both the lack of difference in Experiment 1 and the difference between the out-group condition of Experiment 2 and the baseline.
