有人声称，暴露于一种性别的扭曲面孔会对同一性别的测试面孔产生知觉后效应，但对另一种性别的测试面孔则不会产生知觉后效应（A。C.利特尔湖M. DeBruine，& B. C. Jones，2005）。这一结果表明，男性和女性的面孔有不同的神经编码。考虑到不同性别的面孔在视觉上的高度相似性，这一结果令人惊讶。作者重新研究了男性和女性的面孔编码使用不同的面孔失真。在实验1中，参与者适应了一种性别的扭曲面孔（例如，男性收缩的脸），并与两种性别的脸进行测试。男性和女性的面孔都有后效应，这表明存在共同的编码机制。在实验2和3中，参与者适应了来自两种性别的相反扭曲的面孔（男性收缩和女性扩张的面孔）。男性和女性面孔的后效应弱相反，这表明性别选择性面孔编码机制的存在。总之，这些结果表明，共同和性别选择机制编码男性和女性的面孔。
It has been claimed that exposure to distorted faces of one sex induces perceptual aftereffects for test faces that are of the same sex, but not for test faces of the other sex (A. C. Little, L. M. DeBruine, & B. C. Jones, 2005). This result suggests that male and female faces have separate neural coding. Given the high degree of visual similarity between faces of different sexes, this result is surprising. The authors reinvestigated male and female face coding using a different face distortion. In Experiment 1, participants adapted to distorted faces from one sex (e.g., male contracted faces) and were tested with faces of both sexes. Aftereffects were found for both male and female faces, suggesting the existence of common coding mechanisms. In Experiments 2 and 3, participants adapted to oppositely distorted faces from both sexes (male contracted and female expanded faces). Weak opposite aftereffects were found for male and female faces, suggesting the existence of sex-selective face coding mechanisms. Taken together, these results indicate that both common and sex-selective mechanisms code male and female faces.
