The impersistence of false memory persistence

When subjects study lists of thematically related words they sometimes falsely recognise non-presented words related to the theme. The gist extraction account of these findings provided by fuzzy trace theory suggests that false recognition should decline substantially more slowly than true recognition across a delay. In two experiments we demonstrated that corrected recognition of targets and critical lures can decrease by equivalent amounts across a 48-hour delay. However the results for uncorrected recognition were mixed. In Experiment 1 we found evidence that uncorrected recognition of targets declined more rapidly than uncorrected recognition of critical lures. In Experiment 2, we found evidence that uncorrected recognition of targets and critical lures declined at equivalent rates. Results are discussed in terms of their implications for fuzzy trace and source monitoring accounts of false memories.
