人脸处理网络可以快速准确地区分真实人脸和人造人脸，但对于感知者的刺激质量或个体间差异可能影响人脸是否被感知为活的，人们知之甚少。在目前的研究中，创造了不同程度的变形刺激。参与者根据脸在变形连续体的不同层次上是否显得有生气做出判断。这些面孔在情绪表达（快乐vs.中性）和性别方面各不相同。男性面孔在较低的阈值下被判断为有生命（即，更接近连续体的无生命端）。人们也更容易从快乐的表情中感受到活力，而不是中性的表情。这些影响是在两个独立的研究中观察到的，这些研究涉及不同的参与者和不同的刺激组（用洋娃娃变形的动画脸或用计算机生成的脸变形的动画脸）。最后，研究了个体间人格特质差异对动物活力感知的影响。这表明，外部导向的认知风格（述情障碍的一个组成部分）与感知活力的较低阈值有关，因为有活力的脸是由玩偶变形的。研究结果讨论了与动物感知和社会互动的个体间和个体内变异性的关系。(C) 2017年作者。Elsevier Inc.出版。
Discriminating real human faces from artificial can be achieved quickly and accurately by face-processing networks, but less is known about what stimulus qualities or interindividual differences in the perceiver might influence whether a face is perceived as being alive. In the present studies, morphed stimuli differing in levels of animacy were created. Participants made judgements about whether the face appeared animate at different levels along the morph continuum. The faces varied in terms of emotional expression (happy vs. neutral) and gender. Male faces were judged to be animate at a lower threshold (i.e., closer to the inanimate end of the continuum) than female faces. Animacy was also perceived more readily in faces with happy expressions than neutral. These effects were observed across two separate studies involving different participants and different sets of stimuli (animate faces morphed with dolls or those morphed with computer generated faces). Finally, the influence of interindividual variability in personality traits on animacy perception was examined. This revealed that an externally oriented cognitive style, a component of alexithymia, was associated with lower thresholds for perceiving animacy, for animate faces morphed with dolls. The findings are discussed in relation to inter- and intraindividual variability in animacy perception and social interaction. (C) 2017 The Authors. Published by Elsevier Inc.
