Differentiating emotional processing and attention in psychopathy with functional neuroimaging

Area of Science:

• Neuroscience
• Psychology
• Forensic Psychology

Background:

• Individuals with psychopathy exhibit emotional processing deficits.
• Attention mechanisms are implicated in these emotional abnormalities.
• Neural underpinnings require further investigation.

Purpose of the Study:

• To investigate attention-emotion interactions in psychopathy using functional neuroimaging.
• To explore the neural correlates of emotional processing differences in psychopathic traits.
• To differentiate the roles of attention in implicit and explicit emotional processing.

Main Methods:

• Functional neuroimaging (fMRI) was used.
• 120 incarcerated individuals evaluated for psychopathic traits (Hare Psychopathy Checklist-Revised, PCL-R).
• A task manipulating attention to emotional visual stimuli was employed.

Main Results:

• Factor 1 (affective-interpersonal) associated with lower emotion-dependent visual activity during implicit processing.
• Factor 2 (antisocial-lifestyle) associated with elevated amygdala and salience network activity.
• Explicit emotional processing showed upregulation in medial prefrontal cortex, insula, and superior frontal regions, with Factor 1 linked to visual stream and angular gyrus activity.

Conclusions:

• Attention mechanisms are crucial for understanding emotional processing in psychopathy.
• Distinct neural patterns underlie different facets of psychopathy and their impact on emotional attention.
• Findings highlight neural mechanisms of attention and emotion abnormalities in psychopathy.
