Electrophysiological correlates of episodic memory retrieval are material sensitive

- Abstract
- According to dual-process models of recognition memory, an old/new recognition response can be based on a sense of familiarity and/or recollection of contextual details. Two topographically and functionally distinct ERP old/new effects are held as generic indices of familiarity and recollection respectively. However, episodic retrieval is believed to involve neural reactivation of content-specific information and it remains unclear whether the event-related potential (ERP) correlates of episodic memory are modulated by the type of information retrieved. In two test conditions, we recorded electrophysiological brain activity while participants discriminated between old and new items from three different stimulus categories (faces, objects,... (More)

In two test conditions, we recorded electrophysiological brain activity while participants discriminated between old and new items from three different stimulus categories (faces, objects, and words). In the first test condition, we used a randomized mixed presentation design, whereas in the second test condition we used a blocked presentation design. In both conditions, analyses of the electrophysiological data revealed robust ERP old/new effects for all types of material that differed in their qualitative characteristics, including topographical distribution. Our findings suggest that non-overlapping neural mechanisms support retrieval of mnemonic information differing in terms of perceptual and lexical characteristics. (Less)
