Learning Stories Through Gesture: Gesture's Effects on Child and Adult Narrative Comprehension

摘要

Through providing an external support to speech, gesture observation may benefit a student's learning in a variety of areas, including narrative comprehension. Across two studies, we investigated factors that could moderate when gestures are most beneficial to narrative comprehension, including gesture type, task difficulty, and age, in order to help determine when gestures benefit narrative comprehension most. Crucially, observing typical gestures significantly benefited narrative comprehension (measured by specific questions relating to gesture points) compared with atypical or no gestures, which did not differ significantly. When measured through free recall and specific questions, these effects were not moderated by total task difficulty or age. This finding suggests that how beneficial a gesture is for narrative comprehension may depend more on the kind of gesture observed rather than on age or the difficulty of the task. It may be that typical gestures benefit narrative comprehension more than atypical gestures due to the typical gestures being more semantically related to accompanying speech. In a second study, typical gestures were rated as more semantically related to the speech than were atypical gestures. We argue that educators' use of typical, frequently produced iconic gestures that are adequately semantically related to speech may enhance student understanding.
