RESUMO
Are nonconscious processes sufficient to cause false memories of a nonstudied event? To investigate this issue, we controlled and measured conscious processing in the DRM task, in which studying associates (e.g., bed, rest, awake...) causes false memories of nonstudied associates (e.g., sleep). During the study phase, subjects studied visually masked associates at extremely rapid rates, followed by immediate recall. After this initial phase, nonstudied test words were rapidly presented for perceptual identification, followed by recognition memory judgments. On the perceptual identification task, we found significant priming of nonstudied associates, relative to control words. We also found significant false recognition of these nonstudied associates, even when subjects did not recall this word at study or identify it at test, indicating that nonconscious processes can cause false recognition. These recognition effects were found immediately after studying each list of associates, but not on a delayed test that occurred after the presentation of several intervening lists. Nonconscious processes are sufficient to cause this memory illusion on immediate tests, but may be insufficient for more vivid and lasting false memories.

The authors investigated two retrieval-monitoring processes. Subjects studied red words and pictures and then decided whether test words had been studied in red font (red word test) or as pictures (picture test). Memory confusions were lower on the picture test than on the red word test, implicating a distinctiveness heuristic. Memory confusions also were lower when study formats were mutually exclusive (the same item was never studied as both a red word and a picture), compared with a nonexclusive condition, implicating a recall-to-reject process. When the to-be-recollected events were pictures, older adults used each monitoring strategy as effectively as did younger adults.
