Neural Mechanisms Underlying Individual Differences in Control-Averse Behavior

Area of Science:

• Neuroscience
• Social Psychology
• Decision Science

Background:

• Control aversion, the urge to resist external control over decisions, is common and impacts social interactions.
• Individual differences in control aversion are significant but poorly understood.
• Understanding these differences is crucial for public policy, e.g., in health compliance.

Purpose of the Study:

• To investigate the behavioral and neural mechanisms underlying individual differences in control aversion.
• To identify the role of social cognitions and brain activity in control-averse behavior.

Main Methods:

• fMRI was used to measure brain activity in healthy participants making free versus controlled choices.
• Self-report measures assessed participants' affects, social cognitions, and motivations.
• Behavioral data on choice outcomes were collected with real consequences.

Main Results:

• Perceived distrust and lack of understanding of the controller significantly predicted behavioral control aversion.
• Functional connectivity between the inferior parietal lobule and dorsolateral prefrontal cortex explained neural control aversion.
• Neural connectivity partially mediated the relationship between social cognitions and control aversion.

Conclusions:

• Social cognitions, particularly distrust, are key behavioral drivers of control aversion.
• A neural mechanism involving parietal-prefrontal connectivity underlies individual differences in control aversion.
• This neural mechanism complements self-reported social cognitions, offering a more comprehensive model of control aversion.
