Physically attractive faces attract us physically

<p>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.</p>
