相反，反转的人脸不容易识别，这一效果在物体识别中是不存在的。为什么？提供了四个因素作为解释：专业知识、反射率(着色)、高度相似性以及区分不同度量变化的光滑表面的必要性。观察者在辨别形状光滑、有色、无脸的斑点方面取得了专业知识，这些斑点具有正对比度，其中干扰项的相似性在形状和反射率上与一组面孔相匹配。在匹配到样本的任务中，样本和匹配图像之间的对比度反转在匹配这些斑点时没有影响，但在匹配人脸时显著降低了性能，这表明这种影响是人脸独有的。(C)2007爱思唯尔有限公司。保留所有权利。
Faces reversed in contrast cannot be readily recognized, an effect absent in object recognition. Why? Four factors: expertise, reflectance (pigmentation), high similarity, and the need to discriminate metrically varying smooth surfaces have been offered as explanations. Observers achieved expertise on discriminating smoothly shaped, pigmented, non-face blobs with positive contrast, where distractor similarity matched that of a set of faces in shape and reflectance. On a match-to-sample task, reversal of contrast between sample and matching images had no effect when matching such blobs, but markedly degraded performance when matching faces suggesting that this effect is unique to faces.
