The precision of hippocampal representations predicts incremental value-learning across the adult lifespan

This study shows that hippocampal representation precision predicts value-learning accuracy across age groups, with reduced hippocampal-mPFC connectivity linked to poorer performance in older adults.

Lesions to different regions of frontal cortex have dissociable effects on voluntary persistence

The paper investigates how frontal cortex lesions affect voluntary persistence in a waiting task, finding dissociable effects on waiting duration and learning from feedback.

Neural correlates of age-related changes in social decisions from episodic memory

The paper investigates age-related changes in social decision-making by analyzing neural correlates of trust decisions based on episodic memory in older and younger adults.

Hierarchical Bayesian Models of Reinforcement Learning: Introduction and comparison to alternative methods

This paper introduces hierarchical Bayesian modeling as a method to improve out-of-sample prediction in reinforcement learning by simultaneously extracting and imposing empirical priors.
