Awareness of the False Memory Manipulation and False Recall for People's Names as Critical Lures in the Deese-Roediger-Mcdermott Paradigm

In the present study, people's names were used as Critical Lures (central concept not on the lists) in the Deese-Roediger-McDermott (DRM) paradigm for studying false recall. Following Mukai, the transparency of false memory manipulation in the paradigm was manipulated to explore its influence on false recall. 80 volunteers (age range 17-30 years, M age = 20.9 yr., SD = 1.6) took part. Analyses showed that making the critical lure inconspicuous did not significantly increase false recall. However, the proportion of falsely recalled Critical Lures was significantly lower and the proportion of critical lures produced on a postrecall test (asking participants to report items that they had thought of but did not recall) was significantly higher when they spontaneously realized the nature of false memory manipulation. However, there was no effect on veridical recall of study items. These results suggest that participants strategically avoided reporting false recall for people's names as Critical Lures even without forewarning about false memory.
