Cognitive capacity and control in the evolution of intelligence

The paper develops an evolutionary model of working memory to show how capacity and control interact, with capacity being prioritized due to its role in enabling control.

Apathy-anhedonia is associated with pessimistic beliefs yet sharpened goal-directed planning

The paper shows that apathy-anhedonia is linked to pessimistic beliefs but not reduced goal-directed planning, with enhanced performance in value-based decision-making tasks.

Consolidation of Sequential Planning

This paper investigates how consolidation enhances sequential planning by strengthening neural markers of step-by-step simulation in the brain.

Neural evidence for the successor representation in choice evaluation

The paper provides neural evidence for the successor representation in choice evaluation by linking behavioral errors to predictive representations in sensory cortex.

Predictive representations can link model-based reinforcement learning to model-free mechanisms

This paper proposes a framework linking model-based reinforcement learning to model-free mechanisms using successor representations and introduces algorithms that mitigate their limitations.

The successor representation in human reinforcement learning

This study investigates the successor representation (SR) in human reinforcement learning, showing it balances flexibility and efficiency by being insensitive to task sequence changes but responsive to reward changes.
