Does the cowl make the monk? The effect of military and Red Cross uniforms on empathy for pain, sense of agency and moral behaviors
The present study investigated to what extent the clothes we wear influence prosocial behaviors and two related neuro-cognitive processes, namely the sense of agency and empathy for pain. We tested forty participants wearing civilian, military and Red Cross uniforms across three consecutive days. Participants were tested by pairs and were assigned either to the role of the agent or to the role of the ‘victim’. Agents could deliver real electric shocks to the ‘victim’ in exchange for +€0.05, either following their own decision or following the experimenter’s instructions. Our results indicated that wearing a Red Cross uniform increased the amplitude of the neural response to pain when participants witnessed shocks in comparison with wearing civilian or military clothing. Results also revealed that the sense of agency increased when participants wore a military uniform compared to wearing their own civilian clothing in the Free condition. Finally, participants gave less shocks when wearing the Red Cross uniform compared to wearing their civilian clothing. This study highlights the effect of wearing symbolic uniforms on the sense of agency, on the neural empathic response and on prosocial behavior, thus broadening our knowledge on the impact of ‘enclothed cognition’ on cognitive and psychological processes.
