Abstract: According to Roediger and McDermott (1995), a false memory is a memory of an event that never occurred. A large body of research has explored the false memory effect and the factors that influence false memory production. The purpose of the present study was twofold. The first aim was to examine the extent to which a participant’s confidence in their overall memory ability influences the production of false memories. The second aim was to explore the extent to which fluctuations in memory confidence potentially influence fluctuations in the false memory phenomenon. To these aims, participants were randomly assigned to one of three groups: high-confidence group, low-confidence group, or neutral group. Participants received positive, negative, or neutral feedback about their memory performance on three different memory tests in an attempt to experimentally manipulate participants’ confidence in their memory. Using the Roediger and McDermott (1995) paradigm, participants were administered a total of 32 word lists and were administered a recall test after each list was presented. Each list contained 15 words associated with one non-presented word (critical lure). After all 32 lists were presented, participants completed a recognition test in which they were asked to identify the words presented on each list and to make remember, know, and guess judgments (Tulving, 1985). The analysis on the recall and the recognition test revealed a false memory effect: studied items were recalled and recognized at a higher rate than critical lures which in turn were recalled and recognized at a higher rate than non-critical intrusions or new words. No significant differences between the three memory manipulation conditions were observed, indicating that the memory manipulation did not affect false memory production.
