Unformatted text preview: to find double dissociation between priming and episodic memory. Can find patients who have no episodic memory but still have priming effect, but not the other way around. Its probably due to the initial visual input is necessary to component of Grill-Spector, memory systems, so if that is knocked out, won't have priming, but won't have episodic memory as well. repetition suppression! Henson, & Martin (2006)! Semantic memory = facts about the world. Declarative memory. Squire would say there is no difference between semantic memory and episodic memory, that these patients have just as much trouble learning facts about the world as they do new events.
