Emotion Regulation Contagion: Stress Reappraisal Promotes Challenge Responses in Teammates
How does emotion regulation impact teammates? We present data from a dyadic experiment(N=266) that assessed in vivo stress responses in teammates during collaborative (a face-to-face product design task) and then individual work (a product pitch to evaluators). Throughout the experiment, one manipulated teammate reappraised their stress arousal (reappraisal), suppressed their emotional displays (suppression), or received no instructions (control). Their non- manipulated teammate received no instructions. Stress reappraisal benefited both teammates, eliciting challenge-like physiological responses (higher cardiac output, lower total peripheral resistance) relative to the suppression and control conditions. These effects were observed during both face-to-face collaborative work and later individual work. A mediation model suggests that the face-to-face social contagion effects of stress reappraisal fed forward to promote non- manipulated teammates’ improved stress responses during the individual performance task. These findings indicate that non-manipulated teammates exhibited improved stress responses simply by interacting with a person who reappraised their stress as functional.
