This study shows that Tyrosine supplementation improves reinforcement learning by stabilizing choice behavior and increasing value-driven exploitation in a gender-balanced sample.

This study investigates whether ghrelin modulates risky decision-making through homeostatic state changes but finds no credible effects on behavior or neural activity.

This study assesses the reliability of ambulatory physiological measures during urban walking, finding acceptable test-retest reliability for compound scores derived from cardiovascular and electrodermal activity.

This study investigates reduced model-based control in gambling disorder using reinforcement learning tasks, computational modeling, and fMRI, finding intact neural representations of task structure despite behavioral impairments.

The paper extends a hybrid RL model with a heuristic-based exploration mechanism to analyze two-step sequential decision tasks, finding it better explains choice probabilities in stage one.

This study compares human and recurrent neural network performance in restless bandit tasks, finding human-level RNN performance and distinct exploration strategies.
