Central to perceptual dehumanization theory (PDT) is the claim that full engagement of a putative module for the visual analysis of faces is necessary in order to recognize the humanity or personhood of observed individuals. According to this view, the faces of outgroup members do not engage domain-specific face processing fully or typically and are instead processed in a manner akin to how the brain processes objects. Consequently, outgroup members are attributed less humanity than ingroup members. To the extent that groups are perceptually dehumanized, they are hypothesized to be vulnerable to harm. In our article, we challenge several of the fundamental assumptions underlying this theory and question the empirical evidence in its favor. We begin by illustrating the extent to which the existence of domain-specific face processing is contested within the vision science literature. Next, we interrogate empirical evidence that appears to support PDT and suggest that alternative explanations for prominent findings in the field are more likely. In the closing sections of the article, we reflect on the broader logic of the theory and highlight some underlying inconsistencies.

知觉非人化理论:批评。

感知非人化理论(PDT)的核心是,为了识别被观察个体的人性或人格,必须充分参与面部视觉分析的推定模块。根据这种观点,外群体成员的面部不会完全或典型地参与特定领域的面部处理,而是以类似于大脑处理物体的方式进行处理。因此,外群体成员的人性低于内群体成员。如果某个群体在感知上被非人化,那么他们就被认为很容易受到伤害。在我们的文章中,我们挑战了该理论的几个基本假设,并对有利于该理论的经验证据提出了质疑。我们首先说明视觉科学文献中对特定领域人脸处理的存在存在争议的程度。接下来,我们询问似乎支持 PDT 的经验证据,并表明该领域的突出发现更有可能有其他解释。在本文的最后部分,我们反思了该理论的更广泛逻辑,并强调了一些潜在的不一致之处。
