Perspective taking modulates event-related potentials to perceived pain.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Social Psychology

Background:

• Empathy for pain involves both automatic and controlled neural processes.
• Previous research suggests distinct neural components underlie empathy for pain.

Purpose of the Study:

• To investigate whether perspective-taking modulates automatic versus controlled neural components of empathy for pain.
• To test if adopting a self-perspective or other-perspective differentially affects neural responses to perceived pain.

Main Methods:

• Event-related potentials (ERPs) were recorded from 24 participants.
• Participants judged painfulness of hand images from self or other perspectives.
• ERPs were analyzed for early (automatic) and late (controlled) components.

Main Results:

• Painful stimuli elicited early ERP shifts (160-700 ms) at frontal-central electrodes.
• ERPs at 230-250 ms correlated with subjective pain ratings and unpleasantness.
• A reduced neural response in the central-parietal area (370-420 ms) was observed in the other-perspective condition compared to the self-perspective.

Conclusions:

• Perspective-taking modulates the late, controlled component of neural responses to perceived pain.
• The early, automatic component of empathy for pain appears unaffected by perspective-taking.
• Findings highlight the role of cognitive control in modulating empathic neural responses.
