چکیده انگلیسی
Two identical visual disks moving towards one another on a two-dimensional display can be perceived as either “streaming through” or “bouncing off” each other after their coincidence/overlapping. A brief sound presented at the moment of the coincidence of the disks could strikingly bias the percept towards bouncing, which was termed the audiovisual bounce-inducing effect (ABE). Although the ABE has been studied intensively since its discovery, the debate about its origin is still unresolved so far. The present study used event-related potential (ERP) recordings to investigate whether or not early neural activities associated with cross-modal interactions play a role on the ABE. The results showed that the fronto-central P2 component â¼200â¯ms before the coincidence of the disks was predictive of subsequent streaming or bouncing percept in the unimodal visual display but not in auditory-visual display. More importantly, the cross-modal interactions revealed by the fronto-central positivity PD170 (125-175â¯ms after sound onset), as well as the occipital positivity PD190 (180-200â¯ms), were substantially enhanced on bouncing trials compared to streaming trials in the auditory-visual display. These findings provide direct electrophysiological evidence that early cross-modal interactions contribute to the origin of ABE phenomenon at the perceptual stage of processing.
