When interacting with other humans, facial expressions provide valuable information for approach or avoid decisions. Here, we consider facial attractiveness as another important dimension upon which approach-avoidance behaviours may be based. In Experiments 1-3, we measured participants' responses to attractive and unattractive women's faces in an approach-avoidance paradigm in which there was no explicit instruction to evaluate facial attractiveness or any other stimulus attribute. Attractive faces were selected more often, a bias that may be sensitive to response outcomes and was reduced when the faces were inverted. Experiment 4 explored an entirely implicit measure of approach, with participants passively viewing single faces while standing on a force platform. We found greater lean towards attractive faces, with this pattern being most obvious in male participants. Taken together, these results demonstrate that attractiveness activates approach-avoidance tendencies, even in the absence of any task demand.

身体上吸引人的面孔在身体上吸引了我们。

与其他人互动时，面部表情可为您提供有价值的信息，帮助您避免或做出决策。在这里，我们将面部吸引力视为避免进近行为的另一个重要方面。在实验1-3中，我们在一种避免进入方法中测量了参与者对有吸引力和没有吸引力的女性面部的反应，在该方法中，没有明确的指导来评估面部吸引力或任何其他刺激属性。选择有吸引力的面孔的频率更高，这种偏见可能对响应结果敏感，当面孔倒置时，这种偏见就会减少。实验4探索了一种完全隐式的测量方法，参与者站在力平台上时被动地观看了单张面孔。我们发现更倾向于吸引人的面孔，这种模式在男性参与者中最为明显。综上所述，这些结果表明，即使没有任何任务需求，吸引力也会激活避免接触的倾向。
