This lecture describes recent advances in our understanding of the neural mechanisms responsible for some forms of decision-making. A common framework, known as bounded evidence accumulation or sequential sampling, explains the speed and accuracy of a decision. Recent studies from our lab suggest that this framework also extends to the assignment of confidence that a decision is likely to be correct. I will describe neural recording and microstimulation experiments from nonhuman primates which reveal a common mechanism underling the speed, accuracy and confidence in a decision.
