The ability to rapidly and accurately decode facial expressions is adaptive for human sociality. Although judgments of emotion are primarily determined by musculature, static face structure can also impact emotion judgments. The current work investigates how (fWHR), a stable feature of all faces, influences perceivers' judgments of expressive displays of anger and fear (Studies 1a, 1b, & 2), and anger and happiness (Study 3). Across 4 studies, we provide evidence consistent with the hypothesis that perceivers more readily see anger on faces with high fWHR compared with those with low fWHR, which instead facilitates the recognition of fear and happiness. This bias emerges when participants are led to believe that targets displaying otherwise neutral faces are attempting to mask an emotion (Studies 1a & 1b), and is evident when faces display an emotion (Studies 2 & 3). Together, these studies suggest that target facial width-to-height ratio biases ascriptions of emotion with consequences for emotion recognition speed and accuracy. (PsycINFO Database Record
快速而准确地解读面部表情的能力是人类社交能力的适应性体现。尽管情绪判断主要取决于肌肉活动，但静态的面部结构也会影响情绪判断。目前的研究调查了（fWHR），即所有面孔的稳定特征，如何影响观察者对愤怒和恐惧（研究 1a、1b 和 2）以及愤怒和幸福（研究 3）的表情表达的判断。在 4 项研究中，我们提供的证据与假设一致，即与低 fWHR 相比，观察者更容易在高 fWHR 的面孔上看到愤怒，而这更有利于识别恐惧和幸福。当参与者被引导相信，表现出其他中性表情的目标正在试图掩饰某种情绪时（研究 1a 和 1b），这种偏见就会出现，而当面孔表现出某种情绪时（研究 2 和 3），这种偏见就会显现出来。这些研究表明，目标的面部宽高比偏差会影响对情绪的归因，从而影响情绪识别的速度和准确性。
