Utilizing the high temporal resolution of event-related potentials (ERPs), we compared the time course of processing incongruent color versus 3D-depth information. Participants were asked to judge whether the food color (color condition) or 3D structure (3D-depth condition) was congruent or incongruent with their previous knowledge and experience. The behavioral results showed that the reaction times in the congruent 3D-depth condition were slower than those in the congruent color condition. The reaction times in the incongruent 3D-depth condition were slower than those in the incongruent color condition. The ERP results showed that incongruent color stimuli induced a larger N270, larger P300, and smaller N400 components in the fronto-central region than the congruent color stimuli. Incongruent 3D-depth stimuli induced a smaller N1 in the occipital region, larger P300 and smaller N400 in the parietal-occipital region than congruent 3D-depth stimuli. The time-frequency analysis found that incongruent color stimuli induced a larger theta band (360-580 ms) activation in the fronto-central region than congruent color stimuli. Incongruent 3D-depth stimuli induced larger alpha and beta bands (240-350 ms) activation in the parietal region than congruent 3D-depth stimuli. Our results suggest that the human brain deals with violating general color or depth knowledge in different time courses. We speculate that the depth perception conflict was dominated by solving the problem with visual processing, whereas the color perception conflict was dominated by solving the problem with semantic violation.
利用事件相关电位 (ERPs) 的高时间分辨率，我们比较了处理不一致的颜色与 3D-深度信息的时间进程。要求参与者判断食物颜色（颜色条件）或 3D 结构（3D-深度条件）与他们之前的知识和经验是否一致。行为结果表明，在一致的 3D-深度条件下的反应时间比在一致的颜色条件下慢。在不一致的 3D-深度条件下的反应时间比在不一致的颜色条件下慢。ERP 结果表明，不一致的颜色刺激在前额中央区域引起比一致颜色刺激更大的 N270、更大的 P300 和更小的 N400 成分。不一致的 3D-深度刺激在枕部区域引起更小的 N1，在顶枕部区域引起更大的 P300 和更小的 N400，而一致的 3D-深度刺激则没有。时频分析发现，不一致的颜色刺激在前额中央区域引起比一致颜色刺激更大的 theta 波段（360-580ms）激活。不一致的 3D-深度刺激在顶区引起比一致的 3D-深度刺激更大的 alpha 和 beta 波段（240-350ms）激活。我们的结果表明，大脑以不同的时间进程处理违反一般颜色或深度知识的信息。我们推测，深度感知冲突主要由视觉处理来解决，而颜色感知冲突主要由语义违反来解决。
