Previous research has tested whether culture moderates the relationship between head tilt and perceptions of a cooperation-relevant construct. In this paper, we replicated the effects of head posture on perceived traits and compared Chinese and American participants to explore whether difference in cultural background (collectivist and individualist) affects perceptual attribution. Specifically, we investigated how head posture (level, up or down) affects perceptions of cooperativeness. In Experiment 1, Chinese and American participants rated Asian and Caucasian faces in three postures for perceived cooperativeness on a seven-point Likert scale. In Experiment 2, participants ranked the cooperativeness of the three postures of the same faces. In Experiment 3, participants scrolled through face images and manually manipulated vertical head angle to maximise apparent cooperativeness. We found that for both Chinese and American participants a neutral head level posture was perceived as more cooperative than head up and down postures. The optimal head posture for maximised apparent cooperativeness was close to level but with a slight downward rotation. While there was cross-cultural consistency in perceptions, Chinese participants exhibited greater sensitivity to postural cues in their judgments of cooperation compared to American participants. Our results suggest a profound effect of posture on the perception of cooperativeness that is common across cultures and that there are additional subtle cross-cultural differences in the cues to cooperativeness.
先前的研究检验了文化是否会调节头部倾斜与合作相关结构感知之间的关系。在本文中，我们复制了头部姿势对感知特征的影响，并比较了中国和美国参与者，以探索文化背景（集体主义和个人主义）的差异是否会影响感知归因。具体来说，我们研究了头部姿势（水平、向上或向下）如何影响合作的感知。在实验 1 中，中国和美国参与者在三个姿势（水平、向上和向下）下对亚洲和高加索面孔的合作感知进行了七点李克特量表评分。在实验 2 中，参与者对三张面孔的三种姿势的合作程度进行了排名。在实验 3 中，参与者浏览了面部图像，并手动操纵垂直头部角度，以使明显的合作最大化。我们发现，对于中国和美国参与者来说，中立的水平头部姿势比向上和向下的头部姿势被认为更具合作性。最大化明显合作性的最佳头部姿势接近水平，但有轻微的向下旋转。虽然在感知上存在跨文化的一致性，但与美国参与者相比，中国参与者在合作判断中对姿势线索表现出更大的敏感性。我们的研究结果表明，头部姿势对合作感知有深远的影响，这种影响在不同文化中是普遍存在的，而且在合作线索方面还存在额外的微妙的跨文化差异。
