In two studies, implicit false memory was investigated in Korsakoff patients and memory-intact controls following both incidental and intentional encoding in the Deese/Roediger-McDermott (DRM) paradigm. Encoding type was manipulated within-subjects. In addition, participants in Experiment 2 were asked to think aloud, in order to investigate whether conscious activation of the critical lure occurs equally often in both groups under both types of instructions, and whether this affects the likelihood of later false memory. Korsakoff patients showed normal false priming following both types of encoding. They did verbalize less critical lures than controls during intentional encoding, and showed impaired recognition performance. Lure verbalization was shown to contribute to explicit false memory, but had no clear effect on false priming. Together, results point to the conclusion that amnesic patients’ encoding abilities are sufficiently well to obtain normal implicit false memory, and that conscious lure activation is not required to do so.
