The role of pigmentation in face perception
Faces each have distinct pigmentation as well as shape, which suggests that both cues may play a role in the perception of faces. However, there is a common implicit assumption that pigmentation cues are relatively unimportant, and so the role pigmentation plays in face perception has gone largely unexplored. This thesis is a systematic investigation of the role of pigmentation in face recognit...
متن کاملIs pigmentation important for face recognition ?
It is extraordinarily difficult to recognize a face in an image with negated contrast, as in a photographic negative. The variation among faces can be partitioned into two general sources: (a) shape and (b) surface reflectance, here termed `pigmentation'. To determine whether negation differentially affects the processing of shape or pigmentation, we made two sets of faces where the individual ...
متن کاملThe role of face shape and pigmentation in other-race face perception: an electrophysiological study.
Adult observers generally find it difficult to recognize and distinguish faces that belong to categories with which they have limited visual experience. One aspect of this phenomenon is commonly known as the "Other-Race Effect" (ORE) since this behavior is typically highly evident in the perception of faces belonging to ethnic or racial groups other than that of the observer. This acquired disa...

متن کاملHistochemistry of B663 Pigmentation: Ceroid-Like Pigmentation
Since its use was first reported by 8rowne and Hogerzeil in 1962 ('0. /I), 8663, a synthesized phenazine dye, has proven to be an effective drug in the treatment of human leprosy and its use has become worldwide ( 2.7.9 " . 26. 3~. 39. 52. 5.1 ). The most significant and frequent side effect of this compound is an abnormal skin coloration. This can be divided into two types. One is an initial r...
