本研究利用位置匹配任务来研究当面部身份与实验任务无关时，面部敏感的N170事件相关电位成分是否会在重复呈现相同的面部刺激时产生习惯反应。与连续呈现新面孔相比，重复呈现相同面孔时N170振幅逐渐下降。这种N170对面部身份重复的习惯化只发生在无人值守的空间位置。可能代表了相对纯粹的自动早期面部处理观察。(c) 2005 Elsevier Ltd版权所有。
This study utilized a location-matching task to investigate whether the face-sensitive N170 event-related potential component would habituate in its response to the repeated presentation of same face stimuli when face identity was irrelevant to the experimental task. N170 amplitude decreased progressively with repeated presentation of the same face vs. sequential presentation of novel faces. This N170 habituation to face identity repetition occurred only for faces at unattended spatial locations,. likely representing a relatively pure observation of automatic early face processing.
