Abstract
There are multiple types of manual gestures, one category of them being non-representational gestures. In this study, we are interested in whether RTs can be influenced by non-representational gestures. Therefore, participants were presented a VR-avatar which used different forms of non-representational gestures (palm up open hand, addressee pointing, and palm lateral). Participants were asked polar questions (general knowledge vs. personal preference) and had to press keys for a yes or no response. The questions were constructed so that they had either an early or a late answer point. The results show a significant main effect for the answer point, suggesting that questions with an early answer point are answered faster than questions with a late answer point. However, no significant main effect for gesture presence, gesture form, or the interaction between answer point and gesture presence was found. Thus, non-representational gestures seem to be of no influence on addressee’s RTs.
