Two experiments (modeled after J. Deese's 1959 study) revealed remarkable levels of false recall and false recognition in a list learning paradigm. In Experiment 1, subjects studied lists of 12 words (e.g., bed, rest, awake); each list was composed of associates of 1 nonpresented word (e.g., sleep). On immediate free recall tests, the nonpresented associates were recalled 40{\%} of the time and were later recognized with high confidence. In Experiment 2, a false recall rate of 55{\%} was obtained with an expanded set of lists, and on a later recognition test, subjects produced false alarms to these items at a rate comparable to the hit rate. The act of recall enhanced later remembering of both studied and nonstudied material. The results reveal a powerful illusion of memory: People remember events that never happened. False memories—either remembering events that never happened, or remembering them quite differently from the way they happened—have recently captured the attention of both psychologists and the public at large. The primary impetus for this recent surge of interest is the increase in the number of cases in which memories of previously unrecognized abuse are reported during the course of therapy. Some researchers have argued that certain therapeutic practices can cause the creation of false memories, and therefore, the apparent "recovery" of memories during the course of therapy may actually represent the creation of memories (Lindsay {\&} Read, 1994; Loftus, 1993). Although the concept of false memories is currently enjoying an increase in publicity, it is not new; psychologists have been studying false memories in several laboratory paradigms for years. Schacter (in press) provides an historical overview of the study of memory distortions. Bartlett (1932) is usually credited with conducting the first experimental investigation of false memories; he had subjects read an Indian folktale, "The War of the Ghosts," and recall it repeatedly. Although he reported no aggregate data, but only sample protocols, his results seemed to show distortions in subjects' memories over repeated attempts to recall the story. Interestingly, Bartlett's repeated reproduction results never have been successfully replicated by later researchers (see Gauld {\&} Stephenson, 1967; Roediger, Wheeler, {\&} Rajaram, 1993); indeed, Wheeler and Roediger (1992) showed that recall of prose passages (including "The War of the Ghosts") This research was supported by Grant F49620-92-J-0437 from the Air Force Office of Scientific Research.
