Amnesia and the DRM Paradigm: How Encoding Factors (Do Not) Affect Lure Recognition

Van Damme, Ilse; Dewhurst, Stephen A

Abstract

In the DRM paradigm, participants are presented with, and their memory is tested for, lists of words that are associatively related to a non-presented lure word. Recent studies have revealed that amnesic patients show heightened immediate, but diminished delayed false recognition of such related lure words as compared to healthy controls. These findings may reflect deficient encoding, retrieval, or both. In two experiments, the importance of encoding factors was evaluated by investigating whether story contexts would increase delayed lure recognition, and whether personally-relevant content would decrease immediate lure recognition in Korsakoff patients. With delayed testing, patients' lure recognition was consistently lower than controls'. With immediate testing, lure recognition was less frequent for personally-relevant than for neutral materials. However, as opposed to controls, Korsakoff patients did not show a difference in source memory, but merely a change in response bias. Results point to the conclusion that deficient explicit recollection is the main factor determining the difference in false recognition between amnesic patients and controls.
