Decisions are often associated with a degree of certainty, or confidence--an estimate of the probability that the chosen option will be correct. Recent neurophysiological results suggest that the central processing of evidence leading to a perceptual decision also establishes a level of confidence. Here we provide a causal test of this hypothesis by electrically stimulating areas of the visual ...
متن کاملA Bayesian Framework for Modeling Confidence in Perceptual Decision Making
The degree of confidence in one’s choice or decision is a critical aspect of perceptual decision making. Attempts to quantify a decision maker’s confidence by measuring accuracy in a task have yielded limited success because confidence and accuracy are typically not equal. In this paper, we introduce a Bayesian framework to model confidence in perceptual decision making. We show that this model...
