Neurophysiologic evidence for increased retrieval suppression among negative ruminators.

Events (e.g., seeing a familiar face) may initiate retrieval of associated information (e.g., person's name), but not all cue-initiated memory retrieval is welcome (e.g., trauma). Retrieval suppression refers to the ability to halt unwanted retrieval, and any erosion of memory associations in response to repeatedly excluding a memory from consciousness. The current study sought to examine event-related potential (ERP, averaged scalp electrical recordings) correlates of inhibitory cognitive control of memory retrieval and any linkage of such control to ruminative memory styles.
