When subjects study lists of thematically related words they sometimes fals
ely recognise non-presented words related to the theme. The gist extraction
account of these findings provided by fuzzy trace theory suggests that fal
se recognition should decline substantially more slowly than true recogniti
on across a delay. In two experiments we demonstrated that corrected recogn
ition of targets and critical lures can decrease by equivalent amounts acro
ss a 48-hour delay. However the results for uncorrected recognition were mi
xed. In Experiment 1 we found evidence that uncorrected recognition of targ
ets declined more rapidly than uncorrected recognition of critical lures. I
n Experiment 2, we found evidence that uncorrected recognition of targets a
nd critical lures declined at equivalent rates. Results are discussed in te
rms of their implications for fuzzy trace and source monitoring accounts of
false memories.
