最近对老鼠的实验表明，它们对放射状迷宫中发现的首选食物表现出间歇性或何时何地的记忆。虽然对重大事件发生时的记忆表明，老鼠可以在精神上穿越到过去的某个时刻，但另一种可能性是，它们记得食物是多久前发现的。对三组大鼠进行了对以前遇到的食物的记忆测试。不同的小组只能使用何时、多久前或何时+多久前的线索。只有在多长时间前遇到食物的提示才被成功使用。这些结果表明，大鼠的情景记忆与人类的情景记忆有本质上的不同。
Recent experiments with rats suggest that they show episodic- like or what- where- when memory for a preferred food found on a radial maze. Although memory for when a salient event occurred suggests that rats can mentally travel in time to a moment in the past, an alternative possibility is that they remember how long ago the food was found. Three groups of rats were tested for memory of previously encountered food. The different groups could use only the cues of when, how long ago, or when + how long ago. Only the cue of how long ago food was encountered was used successfully. These results suggest that episodic- like memory in rats is qualitatively different from human episodic memory.
