Is Gesture Production Affected by Viewing Motion?

This proposed study aims to investigate the claims made by Hostetter and Alibali's (2008) Gestures as Simulated Action (GSA) framework by examining. gesture rates in participants retelling a story while being exposed to a visual motion-based stimulus. Approximately 25 to 35 participants will be shown a series of cartoon animations that depict motion either upward or downward. After completing a distractor task, participants will be asked to retell the stories while watching a display video that depicts motion either matched or mismatched to the motion of the stimulus video. These retellings will be video-taped, and the gestures produced during speech will be analyzed. It is expected that both gesture rates and gesture sizes will differ between matched and mismatched conditions, as the visual stimulus is expected to affect the level of motor activation during story retell, and therefore affect the gesture rates as proposed by the GSA framework.
