本研究聚焦于自动视觉变化检测过程，试图阐明与双稳图像的外源性驱动感知交替（ePA）相关的神经处理过程。在我们最近的脑电图研究中，我们采用了奇球范式来连续呈现双稳态图像，以记录视觉错配的消极性（vMMN，大脑对偏差者的反应相对于重复呈现的标准者的反应增强，反映了视觉变化检测过程和对偏差者的预测误差）。在行为和神经数据的个体间差异方面，先前报道了vMMN增强与知觉交替促进之间的相关性，表明视觉变化检测过程参与了ePA。然而，记录的vMMN预计会被神经对重复呈现标准的适应所混淆；因此，目前尚不清楚不依赖于神经适应的视觉变化检测是否与ePA相关，反映在“真正的vMMN”中。为了研究这个问题，本研究使用了一种新的刺激范式，基于所谓的等概率范式，以减轻神经适应。结果表明，真实的vMMN显著出现，并与参与者感知交替比例的增加相关。这支持了自动视觉变化检测过程的参与，而不依赖于神经适应，在促进知觉交替。本研究结果对ePA中视觉变化检测过程的参与提供了更深入的理解。
By focusing on the automatic visual change detection process, the present study attempted to clarify neural processing relevant to the exogenously driven perceptual alternation (ePA) of a bistable image. In our recent electroencephalographic study, the oddball paradigm was adopted to the continuous presentation of a bistable image to record visual mismatch negativity (vMMN, a relative enhancement in the brain response to a deviant over a repetitively presented standard, reflecting the visual change detection process and prediction error to the deviant over the standard). In terms of interindividual differences in behavioral and neural data, a correlation was reported previously between the enhancement of vMMN and facilitation of perceptual alternation, suggesting the involvement of the visual change detection process in ePA. However, the vMMN recorded was expected to be confounded by neural adaptation to the repetitively presented standard; thus, it currently remains unclear whether visual change detection not dependent on neural adaptation, reflected in a ‘genuine vMMN’, is relevant to ePA. To examine this issue, the present study used a new stimulation paradigm, based on the so-called equiprobable paradigm, to mitigate neural adaptation. The results showed that a genuine vMMN significantly emerged and correlated with an increase in the proportion of perceptual alternation across participants. This supports the involvement of the automatic visual change detection process, not dependent on neural adaptation, in facilitating perceptual alternation. The present results provide a deeper understanding of the involvement of the visual change detection process in ePA.
