We examine and reject the claim that the past-directed aspect of mental time travel (episodic memory) is unique to humans. Recent work in our laboratory with rats has demonstrated behaviours that resemble “remember, know” judgements about past occasions. Similar to human episodic memory, we can also demonstrate a dissociation in the neural basis of recollection and familiarity in nonhumans.
