Our ability to understand ongoing events depends critically on general knowledge about how different kinds of situations work (schemas), and also on recollection of specific instances of these situations that we have previously experienced (episodic memory). The consensus around this general view masks deep questions about how these two memory systems interact to support event understanding: How do we build our library of schemas? and how exactly do we use episodic memory in the service of event understanding? Given rich, continuous inputs, when do we store and retrieve episodic memory “snapshots”, and how are they organized so as to ensure that we can retrieve the right snapshots at the right time? I will present results from relevant behavioral and fMRI experiments, and I will describe a computational model that uses memory-augmented neural networks (i.e., neural networks that learn how to use episodic memory in the service of task performance) to account for cortico-hippocampal interactions.
