Abstract

Spontaneous laughter may serve as an auditory cue to affiliative intent within social contexts, whereas volitional laughter may connote deceptive, or non-affiliative, social communication. It would thus be advantageous to distinguish between affiliative and deceptive laughter to identify and prefer conspecifics genuinely interested in affiliating, particularly those whose current affiliative needs are unmet. Furthermore, women’s greater capability to discriminate between emotional cues should implicate them as being especially favorable toward spontaneous laughter. Because social exclusion heightens interest in affiliation, social exclusion should heighten favorability toward those communicating spontaneous laughter, which should be especially augmented among women. The current research examined both trait and state factors that might be moderate responses to spontaneous and volitional laughter. We experimentally activated affiliative motives and tasked men and women with indicating their preferences for spontaneous and volitional laughs. Although activation of affiliative needs did not alter preferences for laughter, participants ultimately preferred spontaneous laughs over volitional. Women were especially sensitive to laughter’s affiliative value, reporting greater disinterest in affiliating with targets emitting volitional laughs, a finding consistent with research indicating women’s heightened sensitivity toward affiliative cues and sensitivity to potentially exploitive conspecifics due to sexual dimorphism.
