The rhythm of joint action: Synchrony promotes cooperative ability

Although evidence has suggested that coordinated action enhances rapport and fosters cooperation, the possibility that it might also influence the ability to pursue joint goals has yet to be demonstrated. We show that rocking in synchrony enhanced individuals’ perceptual sensitivity to the motion of other entities and thereby increased their success in a subsequent joint-action task that required the ability to dynamically detect and respond appropriately to a partner’s movements. These findings support the view that in addition to fostering social cohesion, synchrony hones the abilities that allow individuals to functionally direct their cooperative motives.     

Synchrony and the social tuning of compassion

Although evidence has suggested that synchronized movement can foster cooperation, the ability of synchrony to increase costly altruism and to operate as a function of emotional mechanisms remains unexplored. We predicted that synchrony, due to an ability to elicit low-level appraisals of similarity, would enhance a basic compassionate response toward victims of moral transgressions and thereby increase subsequent costly helping behavior on their behalf. Using a manipulation of rhythmic synchrony, we show that synchronous others are not only perceived to be more similar to oneself but also evoke more compassion and altruistic behavior than asynchronous others experiencing the same plight. These findings both support the view that a primary function of synchrony is to mark others as similar to the self and provide the first empirical demonstration that synchrony-induced affiliation modulates emotional responding and altruism.     

Jealousy and the threatened self: getting to the heart of the green-eyed monster

Several theories specifying the causes of jealousy have been put forth in the past few decades. Firm support for any proposed theory, however, has been limited by the difficulties inherent in inducing jealousy and examining any proposed mediating mechanisms in real time. In support of a theory of jealousy centering on threats to the self-system, 2 experiments are presented that address these past limitations and argue for a model based on context-induced variability in self-evaluation. Experiment 1 presents a method for evoking jealousy through the use of highly orchestrated social encounters and demonstrates that threatened self-esteem functions as a principal mediator of jealousy. In addition to replicating these findings, Experiment 2 provides direct evidence for jealousy as a cause of aggression. The ability of the proposed theory of jealousy to integrate other extant findings in the literature is also discussed.     

The duality of virtue: Deconstructing the moral hypocrite

The present study examined the processes giving rise to moral hypocrisy, a phenomenon in which individuals judge their own transgressions to be less morally objectionable than the same transgressions enacted by others. Two alternative models of the source of hypocrisy were compared to determine whether hypocrisy results from automatic or volitional biases. Findings demonstrated not only that participants viewed their own transgressions as significantly more “fair” than the same transgressions enacted by others, but also that this bias was eliminated under conditions of cognitive constraint. These findings support the view that hypocrisy stems from volitionally-guided justifications, and thereby suggest that at a more basic level, humans possess a negative response to violations of fairness norms whether enacted by themselves or others.
