Compensation for a large gesture-speech asynchrony in instructional videos

• We investigated the pragmatic effects of gesture-speech lag by asking participants to reconstruct formations of geometric shapes based on instructional films in four conditions: sync, video or audio lag (±1,500 ms), audio only. All three video groups rated the task as less difficult compared to the audio-only group and performed better. The scores were slightly lower when sound preceded gestures (video lag), but not when gestures preceded sound (audio lag). Participants thus compensated for delays of 1.5 seconds in either direction, apparently without making a conscious effort. This greatly exceeds the previously reported time window for automatic multimodal integration.
