This review demonstrates that an individualist view of emotion and regulation is untenable. First, I question the plausibility of a developmental shift away from social interdependency in emotion regulation. Second, I show that there are multiple reasons for emotional experiences in adults to elicit a process of social sharing of emotion, and I review the supporting evidence. Third, I look at effects that emotion sharing entails at the interpersonal and at the collective levels. Fourth, I examine the contribution of emotional (...) sharing to emotion regulation together with the relevant empirical evidence. Finally, the various functions that the social sharing of emotion fulfills are reviewed and the relevance of the social sharing of emotion for emotion scientists is discussed. (shrink)

Research on the origins of human social smiling is presented as a case study of how a species-specific, species-typical behavior may emerge from thousands of momentary events in which a continuously changing biological organism acts to make, respond to, and learn from its experience.

Laughter and yawning can both occur spontaneously and are highly contagious forms of social behavior. When occurring contagiously, laughter and yawning are usually confounded with a social situation and it is difficult to determine to which degree the social situation or stimulus itself contribute to its contagion. While contagious yawning can be reliably elicited in lab when no other individuals are present, such studies are more sparse for laughter. Moreover, laughter and yawning are multimodal stimuli with both an auditory and (...) a visual component: laughter is primarily characterized as a stereotyped vocalization whereas yawning is a predominantly visual signal and it is not known to which degree the visual and auditory modalities affect the contagion of laughter and yawning. We investigated how these two sensory modalities contribute to the contagion of laughter and yawning under controlled laboratory conditions in the absence of a social situation that might confound their contagion. Subjects were presented with naturally produced laughter and yawning in three sensory modalities, and we recorded their reaction to these stimuli. Contagious responses differed for laughter and yawning: overall, laughter elicited more contagious responses than yawning, albeit mostly smiling rather than overt laughter. While the audio-visual condition elicited most contagious responses overall, laughter was more contagious in the auditory modality, and yawning was more contagious in the visual modality. Furthermore, laughter became decreasingly contagious over time, while yawning remained steadily contagious. We discuss these results based on the ontogenetic and phylogenetic trajectories of laughter and yawning. (shrink)
