Towards The Neural Correlates And Functions Of Perceptual Confidence

Perceptual confidence refers to a subjective estimate of the uncertainty of a perceptual decision. Intuitively, we might feel as though a perceptual experience is clear or unclear and have, respectively, high or low confidence in decisions based on those experiences. But what is the relationship between the accuracy of our perceptual decisions and our confidence in them? What, if anything, does the subjective confidence we ascribe to a choice mean for subsequent behavior?
