Cognitive flexibility: neurobehavioral correlates of changing one's mind

Area of Science:

• Neuroscience
• Cognitive Psychology

Background:

• Cognitive flexibility is crucial for adapting to environmental changes.
• Existing tasks often focus on reactive switching, not volitional decisions.
• Real-life flexibility frequently involves changing behavior based on unreliable cues.

Purpose of the Study:

• To assess volitional cognitive flexibility under uncertainty using a novel task.
• To investigate the neural correlates of changing decisions.
• To explore brain connectivity associated with response modification.

Main Methods:

• Developed a "change your mind" task assessing volitional switching without rule-learning.
• Utilized functional magnetic resonance imaging (fMRI) in 40 healthy participants.
• Employed multivariate pattern analysis (MVPA) to predict behavioral changes.

Main Results:

• Participants predominantly repeated choices but changed more after incorrect or negative feedback.
• Increased brain activation observed in inferior frontal junction, anterior insula (AI), anterior cingulate, and dorsolateral prefrontal cortex during response changes.
• Reduced connectivity from AI and orbitofrontal cortex to occipital cortex correlated with changing responses.
• MVPA predicted choice changes with 77% accuracy.

Conclusions:

• The study provides insights into the neural mechanisms of volitional decision-making and cognitive flexibility.
• Findings differentiate reactive and volitional switching, offering a more ecologically valid model.
• This research advances understanding of how the brain supports adaptive behavior in uncertain environments.
