Task-dependent evaluative processing of moral and emotional content during comprehension: An ERP study

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Psycholinguistics

Background:

• Previous research indicated implicit moral judgments involve affective categorization.
• Explicit moral tasks are thought to prioritize semantic-cognitive analysis.
• The role of affective categorization in explicit moral judgments remained unclear.

Purpose of the Study:

• To investigate whether affective categorization occurs during explicit moral judgments.
• To differentiate neural responses to moral versus emotional content under explicit judgment conditions.

Main Methods:

• Two experiments using rapid serial visual presentation of morality and emotion scenarios.
• Participants performed explicit moral judgments on moral materials and emotional judgments on emotion materials (Experiment 1).
• Participants performed emotional judgments on both material types (Experiment 2).
• Event-related brain potentials (ERPs) were recorded to measure neural activity.

Main Results:

• Explicit moral judgments elicited an anterior negativity for immoral versus moral scenarios.
• Explicit emotional judgments elicited a larger posterior positivity (LPP) for negative versus neutral emotional scenarios.
• When judging both material types emotionally, a larger LPP was observed for both moral and emotional scenarios.

Conclusions:

• Explicit moral judgments primarily engage semantic-cognitive processing.
• Explicit emotional judgments engage affective processing, indicated by the LPP.
• The findings support distinct neural pathways for judging moral versus emotional content.
