AbstractTheoretical accounts postulate that the catecholaminergic neuromodulator noradrenaline shapes cognitive behavior by reducing the impact of prior expectations on learning, inference, and decision-making. A ubiquitous effect of dynamic priors on perceptual decisions under uncertainty is choice history bias: the tendency to systematically repeat, or alternate, previous choices, even when stimulus categories are presented in a random sequence.
