چکیده انگلیسی
Based on the predictive coding framework, the present behavioral study focused on the automatic visual change detection process, which yields a concomitant prediction error, as one of the visual processes relevant to the exogenously-driven perceptual alternation of a bistable image. According to this perspective, we speculated that the automatic visual change detection process with an enhanced prediction error is relevant to the greater induction of exogenously-driven perceptual alternation and attempted to test this hypothesis. A modified version of the oddball paradigm was used based on previous electroencephalographic studies on visual change detection, in which the deviant and standard defined by the bar's orientation were symmetrically presented around a continuously presented Necker cube (a bistable image). By manipulating inter-stimulus intervals and the number of standard repetitions, we set three experimental blocks: HM, IM, and LM blocks, in which the strength of the prediction error to the deviant relative to the standard was expected to gradually decrease in that order. The results obtained showed that the deviant significantly increased perceptual alternation of the Necker cube over that by the standard from before to after the presentation of the deviant. Furthermore, the differential proportion of the deviant relative to the standard significantly decreased from the HM block to the IM and LM blocks. These results are consistent with our hypothesis, supporting the involvement of the automatic visual change detection process in the induction of exogenously-driven perceptual alternation.
