When a smile is still a conflict: Affective conflicts from emotional facial expressions of ingroup or outgroup members occur irrespective of the social interaction context

Abstract

Facial expressions play a crucial role in human interactions. Typically, a positive (negative) expression evokes a congruent positive (negative) reaction within the observer. This congruent behavior is inverted, however, when the same positive (negative) expression is displayed by an outgroup member. Two approaches provide an explanation for this phenomenon. The social intentions account proposes underlying social messages within the facial display, whereas the processing conflict account assumes an affective conflict triggered by incongruent combinations of emotion and the affective connotation of group membership. In three experiments, we aimed at further substantiating the processing conflict account by separating the affective conflict from potential social intentions. For this, we created a new paradigm, in which the participant was an outside observer of a social interaction scene between two faces. Participants were required to respond to the emotional target person that could represent an ingroup or outgroup member. In all three experiments, irrespective of any social intention, responses were consistently affected by the group relation between participant and emotional target, i.e., the affective (in)congruency of the target seen by participants. These results further support the processing conflict account. The implications for the two theoretical accounts are discussed.
