The effects of observing different gestures during storytelling on the recall of path and event information in 5-year-olds and adults

Abstract

This study examined (a) how observing different types of gestures while listening to a story affected the recall of path and event information in 5-year-old children (n = 71) and adults (n = 55) and (b) whether the effects of gesture type on children's recall of information were related to individual differences such as working memory, language abilities, spontaneous gesture use, and gesture production during the recall task. Participants were asked four questions to measure their spontaneous gesture frequency. They then listened to a story that included different path and event information. Depending on the assigned condition, participants listened to the story with the narrator producing iconic gestures (gestures having semantic meaning), beat gestures (rhythmic hand movements), or no gesture. We then asked participants to relate what happened in the story and administered a recognition task about the story. Children were given standardized tests to assess their language and working memory skills. Children and adults best recalled the story after observing iconic gestures as compared with children and adults presented with beat gestures or no gestures. Children who were exposed to iconic gestures during encoding better recalled event information than children in the other conditions. Children's language abilities, but not working memory, were related to their recall performance. More important, children with better expressive language abilities benefitted more from seeing iconic gestures. These results suggest that observing iconic gestures at encoding facilitates recall and that children's language skills could play a role in encoding and using specific information provided by gestures.
