我们研究了记忆中高度熟悉的面孔表征的准确性。在第一个实验中，一幅著名的毛主席肖像被数字化地改变了他两眼之间的距离，每次两个像素。中国大陆的成年人被要求一次看一张原始的或修改过的照片，并被要求确定每张照片是毛主席的还是修改过的。不熟悉毛泽东照片的东亚和高加索参与者同时展示了原始面孔和修改过的面孔，并要求他们确定照片是否相同。中国大陆受试者的记忆阈值接近东亚和高加索受试者的知觉辨别阈值。实验2和实验3排除了实验1的结果是由于照相改变的伪影。目前的研究结果表明，我们对一个非常熟悉的面孔的记忆是高度准确的，至少在眼间配置方面是如此。准确性可能仅受我们视觉系统的感知分辨率能力的限制。
We examined the accuracy of a highly-familiar-face representation in memory. In experiment 1, a famous portrait of Chairman Mao was digitally altered in terms of the distance between his two eyes, two pixels at a time. Mainland Chinese adults were shown the original or altered photos, one at a time, and asked to determine whether each was that of Chairman Mao or altered. Eastern Asian and Caucasian participants, who were unfamiliar with Mao's photo, were shown simultaneously the original face paired with the altered ones and asked to determine whether the photos were identical. The Mainland Chinese participants' memory threshold approximated the perceptual discrimination threshold of the Eastern Asian and Caucasian participants. Experiments 2 and 3 ruled out that the result of experiment I was due to artifacts of photographic alteration. The findings of the present study suggest that our memory of a very familiar face is highly accurate, at least in terms of the interocular configuration. The accuracy is perhaps only limited by the perceptual resolution capacity of our visual system.
