Doctors inhibit social threat empathy in the later stage of cognitive processing: Electrophysiological evidence

Previous studies have found that repeatedly exposed to a threatening situation may reduce doctors' level of empathy, reducing psychological stress and avoiding burnout and compassion fatigue. However, many essential studies found that it does not seem universal but rather modulated by group membership. In this study, we recorded event-related potentials (ERP) when doctors and controls watched visual stimuli describing patients attacking doctors (Threat events) or shaking hands with doctors (Neutral events). The present study showed an early N190 and a later centro-parietal P3 differential amplitude between threat stimuli and neutral stimuli were observed in the controls. For the doctors, there was such ERP differentiation in early N190. However, later stage P3 differential amplitude was not observed. The current research suggests that doctors could regulate empathy and avoid allocating more attention resources when processing social threats to ensure treatment efficiency and avoid burnout.
