Specific electrophysiological components disentangle affective sharing and empathic concern in psychopathy

Area of Science:

• Neuroscience
• Psychology
• Social Cognition

Background:

• Empathic impairment is a key feature of psychopathy.
• Previous research focused on forensic populations and specific empathy components.
• Limited understanding exists regarding empathic concern in psychopathy.

Purpose of the Study:

• To investigate neurodynamic responses to distress under affective sharing and empathic concern contexts.
• To examine the influence of psychopathy and dispositional empathy on these responses.
• To differentiate neural markers of affective sharing and empathic concern.

Main Methods:

• High-density electroencephalography (EEG) in a community sample.
• Analysis of spatiotemporal neurodynamic responses to viewing individuals in distress.
• Examination of event-related potentials (ERPs), gamma coherence, and mu/alpha band activity.

Main Results:

• Early automatic and later controlled neural responses were differentially modulated by affective sharing and empathic concern.
• Late ERPs and gamma coherence were significantly influenced by dispositional empathy and psychopathy.
• Higher psychopathy scores correlated with suppressed mu/alpha band activity and lower subjective empathy ratings.

Conclusions:

• Neural markers for affective sharing and empathic concern can be distinguished electrophysiologically.
• Psychopathy alters later neural processing and connectivity related to empathic concern.
• Findings challenge sensorimotor resonance as the sole basis for empathy in psychopathy.
