Memory research is, and has been, dominated by the study of episodic memory — the encoding and retrieval of recently experienced information. Significantly less attention has been given to semantic memory — our existing knowledge networks. Work in my lab lies at an interface between these two approaches: (I) How does knowledge activated (implicitly or explicitly) during an episode affect memory of this episode? To examine this question, we (II) consider how our existing knowledge (parts of which become activated during an episode) is organized and stored.
