Research on social exclusion suggests an increased attention of excluded persons to subtle social cues. In one study (N= 32), published inPsychological Science,Bernstein et al. (2008)provided evidence for this idea by showing that participants in the social exclusion condition were better in correctly categorizing a target person’s smile as real or fake. Although highly cited, this finding has never been directly replicated. The present study aimed to fill that gap. 201 participants (79.1% female) were randomly assigned to a social exclusion, (...) social inclusion or control condition. Next, participants watched 20 videos of smiling persons and rated whether they show a real or a fake smile. In line with the original study, results showed that participants in the exclusion condition performed better than in the control condition. However, the performance did not differ between the exclusion and inclusion condition—although the pattern was in the predicted direction. In sum, the findings of our study increase rather than decrease confidence in the validity of the investigated idea, but results point to a substantially smaller effect. (shrink)

The accurate recognition of emotion is important for interpersonal interaction and when navigating our social world. However not all facial displays reflect the emotional experience currently being felt by the expresser. Indeed faces express both genuine and posed displays of emotion. In this article, we summarise the importance of motion for the recognition of face identity before critically outlining the role of dynamic information in determining facial expressions and distinguishing between genuine and posed expressions of emotion. We propose that both (...) dynamic information and face familiarity may modulate our ability to determine whether an expression is genuine or not. Finally, we consider the shared role for dynamic information across different face recognition tasks and the wider impact of face familiarity on determining genuine from posed expressions during real-world interactions.

Research has shown that context influences how sincere a smile appears to observers. That said, most studies on this topic have focused exclusively on situational cues (e.g. smiling while at a party versus smiling during a job interview) and few have examined other elements of context. One important element concerns any knowledge an observer might have about the smiler as an individual (e.g. their habitual behaviours, traits or attitudes). In this manuscript, we present three experiments that explored the influence of (...) such knowledge on ratings of smile sincerity. In Experiments 1 and 2, participants rated the sincerity of Duchenne and non-Duchenne smiles after having been exposed to cues about the smiler’s tendency to reciprocate (this person always, never or occasionally returns favours). In Experiment 3 they performed the same task but with cues about the smiler’s love of learning (this person always, never or occasionally enjoys learning new tasks). The results show that cues about the smiler’s reciprocity tendency influenced participants’ ratings of smile sincerity and did so in a stronger manner than cues about the smiler’s love of learning. Overall, these results both strengthen and broaden the literature on the role of context on judgements of smile sincerity. (shrink)

Smiles that vary in muscular configuration also vary in how they are perceived. Previous research suggests that “Duchenne smiles,” indicated by the combined actions of the orbicularis oculi and the zygomaticus major muscles, signal enjoyment. This research has compared perceptions of Duchenne smiles with non-Duchenne smiles among individuals voluntarily innervating or inhibiting the orbicularis oculi muscle. Here we used a novel set of highly controlled stimuli: photographs of patients taken before and after receiving botulinum toxin treatment for crow’s feet lines (...) that selectively paralyzed the lateral orbicularis oculi muscle and removed visible lateral eye wrinkles, to test perception of smiles. Smiles in which the orbicularis muscle was active were rated as more felt, spontaneous, intense, and happier. Post treatment patients looked younger, although not more attractive. We discuss the potential implications of these findings within the context of emotion science and clinical research on botulinum toxin. (shrink)
