Contrast effect of emotional context on interpersonal distance with neutral social stimuli
In social interactions, valence-based judgements are an important component of interpersonal distances regulation. Within the framework of the Range-Frequency model, we tested whether the emotional context, which is known to produce a contrast effect on valence ratings, also contributes to the regulation of interpersonal distances. 51 participants divided in two groups were shown virtual characters with either a neutral facial expression (target-stimuli) or an emotional facial expression (contextual stimuli) in two successive sessions (angry then happy emotional context or vice-versa). The participants rated the valence of the virtual characters and judged the appropriateness of different interpersonal distances. For neutral characters, contrast effect of emotional context was observed, albeit only subtly on interpersonal distance judgments. Overall, the data suggest that although the emotional context influences valence-based judgments of social stimuli, it has a parsimonious effect on interpersonal distance regulation, presumably because the latter relies primarily on emotional facial expression categorical-information.
