Specifically, these subjects were better at recalling episodic memories, those that involve a specific time and a place. "In an episodic memory, you have contextual detail," said senior author Jesse Rissman, an assistant professor of psychology and of psychiatry and biobehavioral sciences at the University of California, Los Angeles.
