This study examines how high-intensity exercise affects perceptual decision-making using drift diffusion modeling, finding improved performance and changes in evidence accumulation and non-decision time.

The paper investigates how action planning affects perceptual confidence, finding that incongruent action plans increase confidence through enhanced action monitoring.

This study shows that peer presence and unfamiliarity reduce cocaine intake in rats and humans, with the subthalamic nucleus mediating this effect.

The paper shows that subthreshold motor activity correlates with perceptual confidence, suggesting motor processes influence confidence beyond sensory evidence.

The paper analyzes the effects of prolonged physical exercise on cognitive control and working memory, finding no decline in performance due to physical fatigue but evidence of cognitive fatigue from task repetition.

This study shows that peer presence and unfamiliarity reduce cocaine and stimulant intake in both rats and humans.
