This study examines how intolerance of uncertainty affects behavioural flexibility in a reversal learning task, finding associations with reinforcement sensitivity and performance following reward changes.

The paper examines how intolerance of uncertainty relates to neural responses in the prefrontal cortex during uncertain threat scenarios.

This study investigates whether intolerance of uncertainty (IU) affects reward extinction, finding that IU is linked to increased corrugator activity to neutral cues during reward learning but not to valence ratings or SCRs.

This study links longitudinal decline in executive function with increased prefrontal and amygdala activation during emotion reappraisal and reduced white matter integrity in older adults.

This study investigates how intolerance of uncertainty affects threat extinction by comparing responses to uncertain stimuli with varying threat levels.

This study finds that younger age is associated with greater amygdala activity and delayed mPFC engagement during fear extinction, mediated by structural integrity of the uncinate fasciculus.

This study examines how intolerance of uncertainty (IU) influences anticipatory physiological responses in different uncertain contexts, finding context-specific effects on skin conductance and corrugator supercilii activity.

This study shows that contingency instructions reduce threat extinction in individuals with high intolerance of uncertainty.

This study examines how intolerance of uncertainty (IU) affects threat learning and reversal in a paradigm where threat and safety contingencies are reversed, finding that higher IU is linked to stronger physiological responses to new threat cues during reversal.
