Differentiating guilt and shame in an interpersonal context with univariate activation and multivariate pattern...

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Guilt and shame are social emotions typically arising from interpersonal interactions.
• Previous research has not directly compared the neural processing of guilt and shame within an interpersonal context.
• Understanding these distinct emotions is crucial for comprehending social behavior and mental health.

Purpose of the Study:

• To investigate the neural correlates of guilt and shame processing during interpersonal interactions.
• To differentiate the brain regions involved in guilt versus shame in a social context.
• To explore the role of theory of mind and self-referential processing in these emotions.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was employed to measure brain activity.
• Participants engaged in an interpersonal task where their advice affected a confederate's economic outcome.
• Behavioral responses and fMRI data were analyzed, including univariate activation and multivariate pattern analysis.

Main Results:

• Both guilt and shame activated the dorsal medial prefrontal cortex (dmPFC) and anterior insula, involved in self-referential and emotional processing.
• Guilt, relative to shame, showed increased activation in regions associated with theory of mind (supramarginal gyrus, temporo-parietal junction) and cognitive control (orbitofrontal cortex, ventrolateral prefrontal cortex, dorsolateral prefrontal cortex).
• Multivariate pattern analysis identified the ventral anterior cingulate cortex and dmPFC as key areas distinguishing guilt from shame.

Conclusions:

• Guilt and shame share overlapping neural substrates related to self-awareness and emotion.
• Guilt processing in an interpersonal context recruits additional brain networks involved in understanding others' mental states and regulating cognitive processes.
• These findings provide novel insights into the distinct neural mechanisms underlying guilt and shame in social situations.
