In most studies of facial attractiveness perception, judgments are based on the whole face images. Here we investigated how attractiveness judgments from parts of faces compare to perceived attractiveness of the whole face, and to each other. We manipulated the extent and regions of occlusion, where either the left/right or the top/bottom half of the face was occluded. We also further segmented the face into relatively small horizontal regions involving the forehead, eyes, nose, or mouth. The results demonstrated the correlated nature of face regions, such that an attractiveness judgment for one face part can be highly predictive of the attractiveness of the whole face or the other parts. The left/right half of the face created more accurate predictions than the top/bottom half. Judgments involving a larger area of the face (i.e., left/right or top/bottom halves) produced more accurate predictions than those derived from smaller regions, such as the eyes or the mouth alone, but even the smallest and most featureless region investigated (the forehead) provided useful information. The correlated nature of the attractiveness of face parts shows that perceived attractiveness is determined by multiple covarying cues that the visual system can exploit to determine attractiveness from a single glance.

从面部部位预测吸引力揭示了多个共变线索

在大多数关于面部吸引力感知的研究中，判断是基于整个面部图像。在这里，我们研究了面部部分的吸引力判断与整个面部的感知吸引力以及彼此之间的吸引力判断。我们操纵了遮挡的范围和区域，其中面部的左/右或上/下半部分被遮挡。我们还进一步将面部分割成相对较小的水平区域，包括前额、眼睛、鼻子或嘴巴。结果证明了面部区域的相关性，因此对一个面部部分的吸引力判断可以高度预测整个面部或其他部分的吸引力。人脸的左/右半部分比上半部分/下半部分产生更准确的预测。涉及较大面部区域的判断（即，左/右或上/下半部分）产生的预测比从较小区域（例如仅眼睛或嘴巴）得出的预测更准确，但即使是研究的最小和最无特征的区域（前额）也提供了有用的信息。面部部分吸引力的相关性质表明，感知吸引力是由视觉系统可以利用的多个共变线索确定的，从而通过单次浏览来确定吸引力。
