[HTML][HTML] Neural correlates of decision thresholds in the human subthalamic nucleus
If humans are faced with difficult choices when making decisions, the ability to slow down
responses becomes critical in order to avoid suboptimal choices. Current models of decision …

Strategically managing learning during perceptual decision making
Making optimal decisions in the face of noise requires balancing short-term speed and
accuracy. But a theory of optimality should account for the fact that short-term speed can …
