| Research Abstract |
The present study demonstrated that the internal representation of apparent motion(AM) stimuli could perceptually mask the visual awareness of other objects. It was found that target detection performance was degraded within an AM trajectory(AM interference). Further, this AM interference weakened when the differences in orientation between the AM stimuli and target became greater. These findings suggest that AM stimuli and their internal representations affect lower visual processes involved in detecting a pattern in the AM trajectory, and that the internal object representation of an AM stimulus selectively contains and maintains the stimulus attribute. Further, the current study showed that transient sounds presented together with AM stimuli could enhance the magnitude of AM interference. This auditory effect attenuated when frequencies of the sounds were inconsistent during AM. We also confirmed that the sounds wholly elevated the magnitude of AM interference irrespective of the inconsistency in orientation information between the target and AM stimuli. These results suggest that sounds can contribute to the robust establishment and spatiotemporal maintenance of the internal object representation of an AM stimulus.
