Accounts of decision-making and its neural substrates have long posited the operation of separate, competing valuation systems in the control of choice behavior. Recent theoretical and experimental work suggest that this classic distinction between behaviorally and neurally dissociable systems for habitual and goal-directed (or more generally, automatic and(More)
Decision making and reinforcement learning over movements suffer from the curse of dimensionality: the space of possible movements is too vast to search or even represent in its entirety. When actions involve only a single effector, this problem can be ameliorated by considering that effector separately; accordingly, the brain's sensorimotor systems can(More)
A converging body of work suggests that cognitive control operates via two distinct operating modes – proactive control and reactive control, dissociable on a number of dimensions, such as computational properties, neural substrates, temporal dynamics, and consequences for information processing. At the same time, two forms of reinforcement learning (RL),(More)
