为了确定脸部感知的本质，几项研究使用了视觉搜索范式，即受试者在分心物中发现一个奇怪的目标。当检测反应时间与设定的大小无关时，奇数元素被称为“弹出”，反映了相关特征的基本机制或地图。以前的一些研究表明，图解表面不会弹出。我们发现，在各种非人脸物体中，自然的人脸刺激确实会弹出。另一方面，动物的脸不会从相同的分类的非人脸物体中突出出来。此外，在另一个目标类别的干扰项中搜索人脸比反向搜索更容易，并且人脸搜索是由整体人脸特征中介的，而不是由人脸部分中介的。我们的结果表明，Pop Out与基本特征和皮质下部区域的关联可能是错误的。取而代之的是，人脸搜索，甚至所有特征搜索，可能反映出对空间和其他属性细节的概括的高级活动。(C)2005爱思唯尔有限公司。保留所有权利。
To determine the nature of face perception, several studies used the visual search paradigm, whereby subjects detect an odd target among distractors. When detection reaction time is set-size independent, the odd element is said to "pop out", reflecting a basic mechanism or map for the relevant feature. A number of previous Studies suggested that schematic faces do not pop out. We show that natural face stimuli do pop out among assorted non-face objects. Animal faces, on the other hand, do not pop out from among the same assorted non-face objects. In addition, search for a face among distractors of another object category is easier than the reverse search, and face search is mediated by holistic face characteristics, rather than by face parts. Our results indicate that the association of pop out with elementary features and lower cortical areas may be incorrect. Instead, face search, and indeed all feature search, may reflect high-level activity with generalization over spatial and other property details. (c) 2005 Elsevier Ltd. All rights reserved.
