title: The influence of distinctive processing manipulations on older adults' false memory.
abstract: Covertly generating item-specific characteristics for each studied word from DRM (Deese-Roediger-McDermott) lists decreases false memory in young adults. The typical interpretation of this finding is that item-specific characteristics act as additional unique source information bound to each studied item at encoding, and at retrieval young adults can use the absence of this type of information to reject non-presented associated words that might otherwise be falsely remembered. In two experiments, we examined whether healthy older adults could use this strategy to reduce their false memories in the DRM paradigm. In Experiment 1, low frontal lobe functioning was associated with increased false memory in the item-specific strategy condition. Experiment 2 found more memory intrusions under item-specific encoding and the same amount of false memory in auditory and visual presentation conditions, i.e., no modality effect, even with 8 s of encoding time. Both findings are consistent with impaired distinctive processing by older adults.
