summaryGoal-directed or model-based control faces substantial  computational challenges in deep planning problems. One  popular solution to this is habitual or model-free control  based on state-action values. In a simple planning task,  we found evidence for three further heuristics: blinkered  pruning of the decision-tree, the storage and direct  reproduction of sequences of actions arising from search,  and hierarchical decomposition. I will discuss models of  these and their interactions. This is work with Quentin Huys  in collaboration with Niall Lally, Jon Roiser and Sam Gershman.
