Rethinking the distinction between episodic and semantic memory: Insights from the past, present, and future.

On the 50th anniversary of Tulving's introduction of the celebrated distinction between episodic and semantic memory, it seems more than fitting to revisit his proposal in light of recent conceptual and methodological advances in the field. This Special Issue of Memory & Cognition brings together researchers doing cutting-edge work at the intersection between episodic and semantic memory to showcase studies directly probing this psychological distinction, as well as articles that seek to provide conceptual and theoretical accounts to understand their interaction. The 14 articles presented here highlight the need to critically examine the way in which we conceptualize not only the relationship between episodic and semantic memory, but also the interplay between declarative and non-declarative memory, and the myriad implications of such conceptual changes. In many ways, we suggest this Special Issue might serve as a call to action for our field, inspiring future work to challenge pre-existing conceptions and stimulate new directions in this fast-moving field.
