In 5 experiments, the source-monitoring framework was applied to the Deese-
Roediger-McDermott (DRM) paradigm, which has received so much interest rece
ntly. The authors' goal was to demonstrate that under certain conditions, w
hen items in the DRM paradigm were learned from more than 1 origin, the inc
idence of false memories would decline. This result was obtained with inter
nal-external reality monitoring conditions in free recall (Experiments I an
d 3). With more confusable sources that required internal-internal or exter
nal-external discriminations, there was no reduction in false recall (Exper
iments 2a and 4). In all experiments, participants were willing to assign a
n origin to their false memories, even when given an option to claim that t
hey were not sure of its source (Experiment 2b). The results are discussed
in terms of how source-monitoring principles can sometimes reduce false mem
ories in the DRM paradigm.
