On the Synchrony between Figure Movement and Sound Change

To know about the correspondence between visual moving objects and auditory signals is useful in the production of image entertainments and multimedia information via communication network systems. In addition, it can contribute to fundamental research into the time perception in different modalities and the phenomenon of synesthesia. Subjective impression of synchrony between visual motion of a disk and auditory signal was examined in this study. The synchronization between the stopping of the motion of a disk on a screen and that of sound seemed to be important for the judgment of synchrony between audio-visual stimuli. The synchronization between the starting points of both stimuli seemed to be less important for the judgment of synchrony. The existence of a visual framework in the screen played little role for the synchrony at the point of stopping.
