TY - JOUR T1 - Humans flexibly incorporate attention-dependent uncertainty into perceptual decisions and confidence JF - bioRxiv DO - 10.1101/175075 SP - 175075 AU - Rachel N. Denison AU - William T.

Here we show that human decision-making accounts for uncertainty arising not only from external factors, but from the observer’s cognitive state. We manipulated uncertainty in an orientation categorization task from trial to trial using only an attentional cue. Category and confidence decision boundaries shifted in an approximately Bayesian fashion. This responsiveness likely improves perceptual decisions in natural vision. ER -
