The heritability of reinforcement learning parameters and their association with anxiety

The paper examines the heritability of reinforcement learning parameters related to anxiety, finding extinction learning rates correlate with anxiety severity but show no heritability, while safety learning rates have modest heritability but no genetic overlap with anxiety.

Computational modelling reveals slower safety learning and threat extinction are associated with higher anxiety severity in remote fear conditioning

The paper uses computational modeling to show that higher anxiety severity is linked to slower safety learning and threat extinction in fear conditioning tasks.

Anxiety makes time pass quicker: neural correlates

The paper investigates how anxiety affects time perception by examining neural correlates in the cingulate cortex using fMRI and temporal bisection tasks.

Approach-avoidance reinforcement learning as a computational and translational model of anxiety-related avoidance

This paper develops a translational approach-avoidance reinforcement learning task to study anxiety-related avoidance, finding that higher task-induced anxiety correlates with greater punishment sensitivity and avoidance behavior.
