Abstract: The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, in idual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychological and situational factors (for ex le, the intent of the agent or the presence of physical contact between the agent and the victim) can play an important role in moral dilemma judgements (for ex le, the trolley problem). Our knowledge is limited concerning both the universality of these effects outside the United States and the impact of culture on the situational and psychological factors affecting moral judgements. Thus, we empirically tested the universality of the effects of intent and personal force on moral dilemma judgements by replicating the experiments of Greene et al. in 45 countries from all inhabited continents. We found that personal force and its interaction with intention exert influence on moral judgements in the US and Western cultural clusters, replicating and expanding the original findings. Moreover, the personal force effect was present in all cultural clusters, suggesting it is culturally universal. The evidence for the cultural universality of the interaction effect was inconclusive in the Eastern and Southern cultural clusters (depending on exclusion criteria). We found no strong association between collectivism/in idualism and moral dilemma judgements.

Abstract: Following theories of emotional embodiment, the facial feedback hypothesis suggests that in iduals' subjective experiences of emotion are influenced by their facial expressions. However, evidence for this hypothesis has been mixed. We thus formed a global adversarial collaboration and carried out a preregistered, multicentre study designed to specify and test the conditions that should most reliably produce facial feedback effects. Data from n = 3,878 participants spanning 19 countries indicated that a facial mimicry and voluntary facial action task could both lify and initiate feelings of happiness. However, evidence of facial feedback effects was less conclusive when facial feedback was manipulated unobtrusively via a pen-in-mouth task.

Abstract: In this research, we replicated the effect of muscle engagement on perception such that the recognition of another’s facial expressions was biased by the observer’s facial muscular activity (Blaesi & Wilson, 2010). We extended this replication to show that such a modulatory effect is also observed for the recognition of dynamic bodily expressions. Via a multi-lab and within-subjects approach, we investigated the emotion recognition of point-light biological walkers, along with that of morphed face stimuli, while subjects were or were not holding a pen in their teeth. Under the ‘pen-in-the-teeth’ condition, participants tended to lower their threshold of perception of ‘happy’ expressions in facial stimuli compared to the ‘no-pen’ condition thus replicating the experiment by Blaesi and Wilson (2010). A similar effect was found for the biological motion stimuli such that participants lowered their threshold to perceive ‘happy’ walkers in the ‘pen-in-the-teeth’ compared to the ‘no-pen’ condition. This pattern of results was also found in a second experiment in which the ‘no-pen’ condition was replaced by a situation in which participants held a pen in their lips (‘pen-in-lips’ condition). These results suggested that facial muscular activity not only alters the recognition of facial expressions but also bodily expression.

Abstract: Following theories of emotional embodiment, the facial feedback hypothesis suggests that an in idual’s subjective experience of emotion is influenced by their facial expressions. Evidence for this hypothesis, however, has been mixed. We formed a global adversarial collaboration designed to specify and test the conditions that should most reliably produce facial feedback effects. Data from 3,878 hypothesis-unaware participants from 19 countries indicated that a facial mimicry and voluntary facial action task could both lify and initiate feelings of happiness. Evidence, however, was less conclusive when unobtrusively manipulating facial feedback via a pen-in-mouth task. When present, the effects of facial feedback on happiness were similar in size to the effect of mildly pleasant images.
