Event-related brain potentials (ERPs) were recorded in response to centrally and peripherally presented faces and chairs under conditions where one stimulus category was attended and the other unattended. It was studied whether selective attention affects ERP components sensitive to the presence of faces. When compared with chairs, faces elicited larger N1 amplitudes at lateral temporal electrodes and a midline positivity in the same latency range. The latter effect was only found for central faces. Attention to centrally presented faces was reflected in enhanced posterior N1 amplitudes. This effect may be related to an attentional modulation of processing within face-specific brain areas. It was not elicited by chairs or peripheral faces. Beyond 200msec post-stimulus, a category-unspecific attentional negativity was found at all recording sites for centrally and peripherally presented face and nonface stimuli.
事件相关脑电位（ERPs）被记录下来，以响应在中央和外周呈现的面孔和椅子，在一种刺激类别被注意而另一种未被注意的情况下。研究了选择性注意是否会影响对面孔存在敏感的 ERP 成分。与椅子相比，面孔在侧颞电极处引起更大的 N1 振幅，并且在相同的潜伏期范围内出现中线正性。后一种效应仅在中央面孔中发现。对中央呈现的面孔的注意反映在增强的后 N1 振幅上。这种效应可能与对面孔特定脑区的处理的注意力调节有关。它没有被椅子或外周面孔引起。在刺激后 200 毫秒以上，在中央和外周呈现的面孔和非面孔刺激的所有记录部位都发现了一种与类别无关的注意力负性。
