It has been previously shown that prosopagnosics can electrodermally "recognize" faces they cannot verbally identify and with which they feel no familiarity. This study extended previous results by showing that electrodermal discrimination of faces exists only on a famous face identification task, and not on a matching-to-sample task involving unfamiliar faces. This suggests that electrodermal recognition reflects the activation of stored identity-specific information built up on the basis of past contact with faces, and provides a psychophysiological distinction between familiar and unfamiliar face processing. Implications for cognitive models of face recognition, and for understanding the nature of prosopagnosia, are discussed.
先前的研究表明，面孔失认症患者能够通过皮肤电反应“识别”出他们无法用言语辨认且不觉得熟悉的面孔。本研究扩展了先前的结果，表明对面孔的皮肤电反应辨别仅存在于著名面孔识别任务中，而不存在于涉及不熟悉面孔的样本匹配任务中。这表明皮肤电反应识别反映了基于过去对面孔接触而建立的存储身份特定信息的激活，并在熟悉和不熟悉面孔加工之间提供了一种心理生理学上的区分。本文还讨论了对面孔识别认知模型以及对面孔失认症本质理解的意义。
