本研究首次将掩蔽重复启动技术与事件相关电位（ERPs）记录相结合，提出了一种研究客体知觉加工时程的新方法。在语义分类任务中，ERP被记录到重复的和不相关的目标图片的共同对象，立即由简要介绍模式掩盖的主要对象。三个连续的ERP效果之间发现100和650毫秒后的目标发病。这些效应包括早期后正/前负（N/P190），这被认为反映了视觉皮层的早期特征处理。这种早期效应之后是前负性（N300），这被认为是反映了对象特定的表征的处理，最后是广泛分布的负性（N400），这被认为是反映了更多的域一般语义处理。
This study reports a new approach to studying the time-course of the perceptual processing of objects by combining for the first time the masked repetition priming technique with the recording of event-related potentials (ERPs). In a semantic categorization task ERPs were recorded to repeated and unrelated target pictures of common objects that were immediately preceded by briefly presented pattern masked prime objects. Three sequential ERP effects were found between 100 and 650 ms post-target onset. These effects included an early posterior positivity/anterior negativity (N/P190) that was suggested to reflect early feature processing in visual cortex. This early effect was followed by an anterior negativity (N300) that was suggested to reflect processing of object-specific representations and finally by a widely distributed negativity (N400) that was argued to reflect more domain general semantic processing.
