据称，面部对称性很有吸引力，尽管不同研究测量面部对称性偏好的方法有所不同。一些研究使用了两种选择强制选择（2AFC）任务，而另一些研究则使用了评级任务。研究人员操纵面部对称性的方式也各不相同。一些研究使用了被操纵为更加（或完美）对称的面部，而另一些研究则使用了被操纵为更加不对称的面部。在这里，我们通过三项研究评估和比较这些不同的方法。在研究 1 和 2（N = 340 和 256）中，我们比较了通过 2AFC 和评级任务测量的面部对称偏好。在这两项研究中，我们一致发现，在使用 2AFC 任务时，人们对面部对称性有显着偏好，但在评分任务中则不然。此外，这两项任务测量的面部对称偏好之间的相关性很弱或没有显示出关联。在研究 3 中，159 名参与者对被操纵为对称或更加不对称的面孔的吸引力进行了评分。与原始面孔相比，不对称面孔的吸引力明显较低，而原始面孔和对称面孔之间的吸引力评级差异相对较小。这些研究表明，对面部对称性的偏好很大程度上取决于研究设计。
Facial symmetry is purportedly attractive, though methods for measuring preference for facial symmetry vary between studies. Some studies have used a two-alternative forced choice (2AFC) task, while others have used a ratings task. How researchers manipulate facial symmetry also varies; some studies have used faces manipulated to be more (or perfectly) symmetrical, while others have used faces manipulated to be more asymmetrical. Here, across three studies, we evaluate and compare these different methods. In Studies 1 and 2 (N = 340 and 256, respectively), we compare facial symmetry preferences as measured by the 2AFC and ratings tasks. Across both studies, we consistently found a significant preference for facial symmetry when using the 2AFC task, but not with the ratings task. Additionally, correlations between facial symmetry preferences as measured by the two tasks were weak or showed no association. In Study 3, 159 participants rated the attractiveness of faces manipulated to be either symmetrical or more asymmetrical. The asymmetrical faces were rated as significantly less attractive compared to the original faces, while the difference in attractiveness ratings between the original and symmetrical versions was comparatively much smaller. These studies suggest that preference for facial symmetry depends greatly on the study design.
