The importance of prosodic variations in social interaction contexts has been highlighted but their effects on the regulation of specific behaviors are rarely addressed. One of the most widely researched prosodic distinctions in psychology is emotional prosody. In perceptual studies, the capacity for identifying emotions through prosodic variations has been widely addressed, but the relevance of this skill for social interaction has not been tested. However, based on theoretical accounts of emotion and empirical findings of the influence of facial emotional expressions in experiments that address their role in cooperation, it is possible to formulate predictions about the effects of emotional prosody in social interaction behavior. For this objective, in the present work, the effects of emotional prosody on cooperation were addressed, and its interaction with other behavioral intention cues (propositional content) was analyzed. Findings show that emotional prosody influences cooperation behavior but its joint effects with propositional content suggest that a complex inferential process may underlie the integration of contextual and behavioral intention cues to guide behavior. The significance of results and potential for extending future research are discussed.
