Emotions in cognitive conflicts are not aversive but are task specific

Area of Science:

• Cognitive Neuroscience
• Psychophysiology
• Human Emotion

Background:

• Cognitive conflicts are theorized to necessitate effortful processing and be inherently aversive.
• Existing models propose unified cognitive conflict monitoring systems.
• The subjective experience and neural underpinnings of different conflict types require further investigation.

Purpose of the Study:

• To compare the psychophysiological and electrophysiological responses to response inhibition conflicts (go/no-go task) versus response conflict (Simon task).
• To determine if cognitive conflicts are inherently aversive.
• To investigate the neural generators of conflict-sensitive event-related potentials.

Main Methods:

• Employed a within-subjects design comparing go/no-go and Simon tasks using identical stimuli.
• Measured skin conductance, pupillometry, and corrugator muscle activity.
• Analyzed event-related brain potentials, focusing on the N2 component's amplitude and scalp distribution.

Main Results:

• No-go trials showed distinct psychophysiological patterns (reduced skin conductance/pupillometry, increased corrugator activity) compared to go trials.
• Simon task trials (compatible vs. incompatible) did not differ in these psychophysiological measures.
• The N2 component exhibited similar amplitudes but different scalp distributions across conflict types, suggesting distinct neural sources.

Conclusions:

• Different cognitive conflicts engage distinct emotional and cognitive processes.
• Neither response inhibition nor response conflict, as studied here, appears inherently aversive.
• Findings challenge the notion of a single, common monitoring system for all cognitive conflicts due to dissociable neural generators.
