Abstract

Recent findings identified the pupillary response as an important, trust-building signal in social interactions, which differs depending on the affiliation of the counterpart to the in- or outgroup. Based on these studies, the pupil diameter should also vary systematically, depending on the familiarity of a stimulus face. To examine this hypothesis, subjects saw ten mirrored self-face images, which were gradually approximated in eleven steps towards a same-sex friend's face as well as to two same-sex- and two opposite-sex foreign faces (Abrosoft FantaMorph 5.4.5). During the passive reception of the randomized sequence of the facial stimuli, the subject's pupillary responses were recorded using eye tracking (Tobii TX-300). Results show differences in stimulus evoked pupillary responses depending on familiarity (familiar, foreign) and similarity to the self-face (graded approximation). This finding is discussed in the context of current findings regarding the role of the pupillary response in social interactions.
