阐明了基于记忆比较的变化检测在视觉干扰中的作用。不仅涉及基于记忆比较的变化检测和基于不应性的稀有性检测的亮度增量，而且仅涉及基于记忆比较的变化检测的亮度减少也会导致行为分心，这通过反映注意力捕获的后验消极性（240-260 ms，后验 N2）和广泛的积极性（420-460 ms，P3a）反映出来。在这些效应之前，亮度增量引起后验积极性（100-120毫秒，与变化相关的积极性）和后验消极性（120-140毫秒，与变化相关的消极性），而亮度减少仅引起后验积极性（160-180毫秒，与变化相关的积极性）。这些结果表明，以变化相关的积极性为索引的基于记忆比较的变化检测涉及由于注意力捕获而导致的视觉分散。
The involvement of memory-comparison-based change detection in visual distraction was elucidated. Not only luminance increments that engaged memory-comparison-based change detection and refractoriness-based rareness detection but also luminance decrements that engaged only memory-comparison-based change detection caused behavioral distraction, which was mirrored by a posterior negativity (240-260 ms, posterior N2) and a broad positivity (420-460 ms, P3a) that reflected attentional capture. Preceding these effects, luminance increments elicited a posterior positivity (100-120 ms, change-related positivity) and a posterior negativity (120-140 ms, change-related negativity), whereas luminance decrements elicited only a posterior positivity (160-180 ms, change-related positivity). These results suggest that memory-comparison-based change detection indexed by change-related positivity is involved in visual distraction as a result of attentional capture.
