タイトル:Animal models of episodic memory


People retrieve episodic memories about specific earlier events that happened to them.
Accordingly, researchers have sought to evaluate the hypothesis that nonhumans
retrieve episodic memories. The central hypothesis of an animal model of episodic
memory is that, at the moment of a memory assessment, the animal retrieves a memory
of a specific earlier event. Testing this hypothesis requires the elimination of non-
episodic memory hypotheses. We developed of a range of approaches, so that we have
working models to evaluate elements of episodic memory in animals. These
approaches include: what-where- when memory (Zhou & Crystal 2009, PNAS); source
memory (Crystal, Alford, Zhou, & Hohmann 2013, Current Biology); binding of episodic
memories (Crystal & Smith 2014, Current Biology); multiple item-in- context memories
(Panoz-Brown et al., 2016, Current Biology); replay of episodic memories (Panoz-Brown
et al., unpublished); and answering unexpected questions after incidental encoding
(Zhou, Hohmann, & Crystal 2012, Current Biology). In each approach, compelling
evidence for episodic memory comes from studies in which judgments of familiarity
cannot produce accurate choices in memory assessments. These approaches may be
used to explore the evolution of cognition.
