Two experiments are reported on the effect of feature masking on judgements of the sex and familiarity of faces. In experiment 1 the effect of masking the eyes, nose, or mouth of famous and nonfamous, male and female faces on response times in two tasks was investigated. In the first, recognition, task only masking of the eyes had a significant effect on response times. In the second, sex-judgement, task masking of the nose gave rise to a significant and large increase in response times. In experiment 2 it was found that when facial features were presented in isolation in a sex-judgement task, responses to noses were at chance level, unlike those for eyes or mouths. It appears that visual information available from the nose in isolation from the rest of the face is not sufficient for sex judgement, yet masking of the nose may disrupt the extraction of information about the overall topography of the face, information that may be more useful for sex judgement than for identification of a face.
本文报告了两项关于特征掩蔽对面部性别和熟悉度判断影响的实验。在实验1中，研究了对著名和非著名、男性和女性面孔的眼睛、鼻子或嘴巴进行掩蔽，对两项任务反应时间的影响。在第一个识别任务中，仅掩蔽眼睛对反应时间有显著影响。在第二个性别判断任务中，掩蔽鼻子导致反应时间显著大幅增加。在实验2中发现，在性别判断任务中单独呈现面部特征时，对鼻子的反应处于随机水平，这与对眼睛或嘴巴的反应不同。似乎单独从鼻子获取的视觉信息不足以进行性别判断，但掩蔽鼻子可能会干扰对面部整体地形信息的提取，而这些信息对于性别判断可能比对面部识别更有用。
