Smiling when distressed: when a smile is a frown turned upside down

This research tested self-regulation and self-presentation as psychological mechanisms that motivate smiling when distressed. In Study 1, participants viewed moderately and intensely distressing, amusing, and neutral videos in social or nonsocial conditions. Smiling when distressed was most prevalent in conditions in which participants reported the greatest emotional distress. Specifically, while viewing distressing videos, men reported experiencing greater overall distress and also smiled more than women, especially in social conditions and while viewing intensely (as opposed to moderately) distressing stimuli. In general, smiling was related to more negative affect while viewing distressing videos but to more positive affect after viewing such stimuli. Study 2 explored raters' social perceptions of participants from Study 1, confirming that people judge distressed smilers as less socially appropriate and less likable than nonsmilers. Findings suggest that although distressed smiling serves a probable self-regulatory function, it may also bear some negative social consequences.
