Summary

Interoceptive sensibility (IS) influences how neural activity, affect, and value integration predict choices. Higher IS enhances the predictive power of brain activity for aggregate choices, extending decision-making frameworks.

Area Of Science

Neuroscience
Decision Science
Cognitive Science

Background

The Affect-Integration-Motivation (AIM) framework links neural activity to choice prediction.
Interoceptive sensibility (IS) involves heightened awareness of bodily sensations and may influence decision-making coherence.

Purpose Of The Study

Investigate how IS modulates the relationship between neural/affective measures and choice prediction.
Explore neural underpinnings of individual and aggregate choices in mobile gaming.
Test the moderating effect of IS on prediction models.

Main Methods

Neuroimaging techniques to identify neural correlates of choice, affect, and outcomes.
Analysis of affective ratings, neural activity, and behavioral choices (downloads, revenue).
Comparison of prediction models between high and low IS subgroups.

Main Results

Individual choice linked to Nucleus Accumbens (NAcc) activity; aggregate downloads correlated with salience network activity.
Affective ratings and Amygdala Insula (AI) activity predicted individual downloads; medial Prefrontal Cortex (mPFC) activity predicted aggregate downloads.
High IS group showed stronger coherence between neural activity, affect, and choice; mPFC activity significantly predicted aggregate downloads in this group.

Conclusions

IS plays a crucial role in the neurobehavioral mechanisms of decision-making.
The AIM framework is extended by demonstrating IS's influence on integrating neural and affective information for choice.
Findings highlight the importance of interoception in understanding individual and aggregate decision-making patterns.

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...
