Short-term visual memory, as in both implicit priming and explicit recognition tasks, can be demonstrated by decreased reaction times, the ability to preferentially select previously presented objects from lists and the ability to more readily complete previously exposed words from fragmented letters. The visual processing of faces occurs separately from the visual processing of non-face stimuli, within discrete areas of bilateral posterior inferotemporal cortices. While visual recognition and memory of faces are independent of those for non-faces, their processing appears to be similar. We have demonstrated an electrophysiologic correlate of short-term visual memory in a face-matching paradigm. We have observed a series of evoked potential components consisting predominantly of a C140, C180 and C240 with a posterior, bitemporal distribution. The priming effect is reflected by a diminution of C240 amplitude in the response to repeated pictures of faces compared to novel pictures of faces. These data reflect a previously unreported set of neurophysiological observations on short-term visual memory for faces.
短期视觉记忆，如同在隐式启动和显式识别任务中一样，可以通过反应时间的缩短、从列表中优先选择先前呈现的物体的能力以及从碎片化字母中更轻松地完成先前呈现过的单词的能力来证明。面部的视觉处理在双侧后颞下皮质的离散区域内，与非面部刺激的视觉处理是分开进行的。虽然面部的视觉识别和记忆与非面部的视觉识别和记忆相互独立，但它们的处理过程似乎相似。我们已经在面部匹配范式中证明了短期视觉记忆的电生理相关性。我们观察到一系列诱发电位成分，主要由C140、C180和C240组成，分布在后部和双侧颞部。与新面孔图片相比，对重复面孔图片的反应中，C240波幅减小反映了启动效应。这些数据反映了一组以前未报道过的关于面部短期视觉记忆的神经生理学观察结果。
