Temporal processing on audiovisual simultaneity during perception of apparent motion

The relation between visual motion information and temporal perception has a significant effect on the development of man-machine interface. However, the relation is still not fully understood. This study aims to investigate temporal processing of audiovisual simultaneity during perception of apparent motion, which is the fundamental unit of human motion perception. Participants performed an audiovisual temporal order judgment (TOJ) task under two conditions: apparent motion condition and non-apparent motion condition. Our result shows that visual motion information contributes to the acceleration of visual processing and the increase of temporal resolution in temporal processing of audiovisual simultaneity. Our findings will provide useful information to construct the frame of temporal processing in man-machine interface.
