How misinformation alters memories.

Over the past quarter of a century, hundreds of studies have demonstrated that misleading postevent information affects people's memories. Researchers have used several methods to try to understand this phenomenon and have also put forward different theories to account for the effect. Brainerd and Reyna's (1998, this issue) conjoint misinformation method and their fuzzy-trace theory are welcomed additions on both these fronts. We describe how their contribution fits with the other methods and theories which have been used to understand how misleading postevent information affects people's memory.

Errors in autobiographical memory.

Memory is always constructive. People create the past based on the information that remains in memory, their general knowledge, and the social demands of the retrieval situation. Thus, memories will often contain some small errors and occasionally some large errors. In this article, we describe several different types of memory errors and consider how these errors may influence therapy.

How memory research can benefit from CASM.

Research on cognitive aspects of survey methodology (CASM) has helped survey researchers to understand the processes involved in responding to survey questions. The survey situation, and the methods employed by CASM researchers, can also be used to benefit cognitive psychology. In particular, the size and coverage of sample surveys, and the techniques used to examine how respondents understand survey questions, could be of much value for exploring some aspects of memory research. We give some examples where this is being done and urge others to follow suit.

Remembering and forgetting childhood sexual abuse.

Out of a large number of university students who responded to a questionnaire about childhood sexual abuse (CSA), approximately a quarter reported that they had an experience in childhood that qualified. The majority of students who reported a CSA experience refused, elsewhere in the questionnaire, to classify themselves as 'sexually abused'. Moreover, those who claimed lack of understanding of the event at the time it occurred also reported that they thought about the event less often in the intervening years and that they conceivably would have not remembered the event even if asked directly about it. Lack of understanding at the time of encoding leads to less reported memory. These observations are discussed in terms of possible mechanisms for how genuine sexual abuse experiences might be temporarily forgotten--even for extended periods--and subsequently remembered.

When dreams become reality.

In three experiments, we found that after a subtle suggestion, subjects falsely recognized words from their own dreams and thought they had been presented during the waking state. The procedure used in these studies involved three phases. Subjects studied a list of words on Day 1. On Day 2, they received a false suggestion that some words from their previously reported dreams had been presented on the list. On Day 3, they tried to recall only what had occurred on the initial list. Subjects falsely recognized their dream words at a very high rate-sometimes as often as they accurately recognized true words. They reported that they genuinely "remembered" the dream words, as opposed to simply "knowing" that they had been previously presented. These findings, which suggest that dreams can sometimes be mistaken for reality, have significant implications for the practice of psychotherapy.

Memory distortion and false memory creation.

The 1990s have brought to public attention thousands of cases that began when a grown-up daughter or son walked into a therapist's office seeking help for depression, low self-esteem, or any of a number of life's problems. Many of these cases grew to involve memories of childhood sexual abuse recovered while in therapy--memories that did not exist, or at least were not remembered, before therapy began. Many of these cases also involved families torn violently apart. What should we make of these new-found memories? Are they true memories that were successfully revived in therapy? Are they false memories that were unwittingly planted? Are they symbolic expressions--historically false but representing some deep underlying truth? Insights from cognitive psychology may shed some light. Much of the litigation that has resulted from the emergence of "repressed memories" has been hazardous to the patients, and their families, as well as to the therapists who treat them.

Misinformation revisited: new evidence on the suggestibility of memory.

In three experiments involving a total of 623 subjects, a series of slides was shown depicting a student in a college bookstore stealing a variety of items. Next, subjects read a narrative describing the event that contained some misinformation and some neutral information about several critical details. Finally, subjects took a memory test. On this test, subjects were asked to list exemplars of 20 specified categories but were instructed not to list any items that they saw in the slide sequence. Analogous to Lindsay's (1990) adaptation of Jacoby, Woloshyn, and Kelley's (1989) "logic-of-opposition" paradigm, the tendency to report suggested details was thus set in opposition to the ability to remember the source of those details. Therefore, we interpreted failure to include suggested details as exemplars as evidence that subjects believed those details had been present in the event. Analysis of subjects' responses under opposition instructions suggests that some misled subjects come to genuinely believe that they saw items that, in reality, were only suggested to them.

Forgetting sexual trauma: what does it mean when 38% forget?

L. M. Williams (1994) has shown that many women who were sexually abused as children do not report the abuse when questioned 2 decades later. These findings do not support certain freely made claims about memory, but they do support other claims. The findings do not provide cogent support for the claim that a long stream of childhood sexual traumas is routinely banished from conscious awareness and then can be reliably recovered later. The findings do support the claim that many children can forget about a sexually abusive experience from their past. Extreme claims such as "if you were raped, you'd remember" are disproven by these findings.

The possible role of source misattributions in the creation of false beliefs among preschoolers.

In this article the authors examine one possible factor in the creation of false beliefs among preschool-aged children, namely, source misattributions. The authors present the results from an ongoing program of research which suggest that source misattributions could be a mechanism underlying children's false beliefs about having experienced fictitious events. Findings from this program of research indicate that, although all children are susceptible to making source misattributions, very young children may be disproportionately vulnerable to these kinds of errors. This vulnerability leads younger preschoolers, on occasion, to claim that they remember actually experiencing events that they only thought about or were suggested by others. These results are discussed in the context of the ongoing debate over the veracity and durability of delayed reports of early memories, repressed memories, dissociative states, and the validity risks posed by therapeutic techniques that entail repeated visually guided imagery inductions.

Pseudomemories without hypnosis.

Hypnosis is often colloquially associated with "the power of suggestion"; however, some cognitive memory researchers believe that suggestions have power even without hypnosis. A well-known phenomenon in cognitive psychology is the "misinformation effect," in which subjects who are misled about previously witnessed events often integrate that inaccurate postevent information into their accounts of the event. In the present article, we review the misinformation literature in four major rounds according to the nature of the memory distortion. The first three rounds are studies of memory suggestibility for observed events; by contrast, the fourth (and newest) one deals with personal or autobiographical memory. Considered collectively, these four rounds of research provide compelling evidence that it is not hard at all to make people truly believe they have seen or experienced something they have not-without any hypnosis at all. Finally, we discuss the tragic implications for the unquestioned acceptance of all recovered memories.

The reality of repressed memories.

Repression is one of the most haunting concepts in psychology. Something shocking happens, and the mind pushes it into some inaccessible corner of the unconscious. Later, the memory may emerge into consciousness. Repression is one of the foundation stones on which the structure of psychoanalysis rests. Recently there has been a rise in reported memories of childhood sexual abuse that were allegedly repressed for many years. With recent changes in legislation, people with recently unearthed memories are suing alleged perpetrators for events that happened 20, 30, even 40 or more years earlier. These new developments give rise to a number of questions: (a) How common is it for memories of child abuse to be repressed? (b) How are jurors and judges likely to react to these repressed memory claims? (c) When the memories surface, what are they like? and (d) How authentic are the memories?

Psychologists in the eyewitness world.

Over the past century, but especially over the past 20 years, psychological studies of eyewitness identification have been accumulating. Wells (1993, this issue) believes that the time is ripe to summarize the research on identification procedures, such as lineups and showups, that will minimize false identifications of innocent people and maximize accurate identifications of the guilty. Other experts in the field worry that there is still too big a leap from the laboratory work to the real world of crime. Identification research, many agree, has the potential for being one of the more useful arenas in which psychological science can make a difference in society.

Desperately seeking memories of the first few years of childhood: the reality of early memories.

How far back into their childhoods can people remember? Previous research suggests that people's earliest memories date back to the ages of 3 or 4 years. J. A. Usher and U. Neisser (1993, this issue) reported that some events, like the birth of a sibling and a planned hospitalization, can be readily remembered if they occurred at age 2. However, the bits and pieces of such memories that were obtained in their research may not be indicative of genuine episodic memory. An alternative hypothesis is that these apparent memories are the result of educated guesses, general knowledge of what must have been, or external information acquired after the age of 2.

Is the unconscious smart or dumb?

How sophisticated is unconscious cognition? This is one of the most fundamental questions about the unconscious that has been posed by research psychologists over the past century. Anthony Greenwald takes a contemporary look at this classical problem and concludes that unconscious cognition is severely limited in its analytic capability. In response, other leading scholars agree that the reality of unconscious processes is no longer questionable. Although there is some disagreement about just how sophisticated these processes are, the consensus is that exciting times are ahead for both research and theory concerning the mental processes involved in unconscious cognition.

Resolving legal questions with psychological data.

Psychologists are ever finding new legal arenas for their psychological data and concepts. Findings about the character and operation of stereotyping have been introduced in sex discrimination litigation in the United States. Findings about conformity, obedience to authority, and bystander apathy have been introduced into death penalty cases in South Africa. These concrete and detailed applications of psychological science demonstrate the expanding role that psychology is playing in the legal world.
