Competition and Cooperation between Model-based and Model-free decisions

Substantial recent work has explored multiple mechanisms of decision-making in humans and other animals. Functionally and anatomically distinct modules have been identified, and their individual properties have been examined using intricate behavioural and neural tools. I will discuss the background of these studies, and describe a number of recent experiments that have cast a stronger, albeit more confusing, light on the interactions between these mechanisms. I will also talk about other related dichotomies of control.
