Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by . Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the conditions with shorter (...) presentation times (20 ms in Experiment 1; 20 and 40 ms in Experiment 2) no memory for studied words, nor a false memory effect was found. We argue that there is at present no strong evidence supporting the claim for a nonconscious basis of the false memory effect. (shrink)

When Cool finally realized that false memories had been planted, she sued the psychiatrist for malpractice. In March 1997, after five weeks of trial, her case was settled out of court for $2.4 million. Nadean Cool is not the only patient to develop false memories as a result of questionable therapy. In Missouri in 1992 a church counselor helped Beth Rutherford to remember during therapy that her father, a clergyman, had regularly raped her between the ages of seven and 14 (...) and that her mother sometimes helped him by holding her down. Under her therapist's guidance, Rutherford developed memories of her father twice impregnating her and forcing her to abort the fetus herself with a coat hanger.The father had to resign from his post as a clergyman when the allegations were made public. Later medical examination of the daughter revealed, however, that she was still a virgin at age 22 and had never been pregnant. The daughter sued the therapist and received a $1-million settlement in 1996. (shrink)

In this essay, I attempt to outline a feminist philosophical approach to the current debate concerning (allegedly) false memories of childhood sexual abuse. Bringing the voices of feminist philosophers to bear on this issue highlights the implicit and sometimes questionable epistemological, metaphysical, and ethical-political commitments of some therapists and scientists involved in these debates. It also illuminates some current debates in and about feminist philosophy.

With growing concerns over children's suggestibility and how it may impact their reliability as witnesses, there is increasing interest in determining the long-term effects of induced memories. The goal of the present research was to learn whether source misattributions found by Ceci, Huffman, Smith, and Loftus caused permanent memory alterations in the subjects tested. When 22 children from the original study were reinterviewed 2 years later, they recalled 77% of all true events. However, they only consented to 13% of (...) all false events, compared to the 22% false consent rate found by Ceci et al. . Additionally, while children remained accurate in their recall of true events , they “recanted” their earlier false consents 77% of the time, after the 2-year delay. Implications of these findings for child witnesses and the legal system are discussed. (shrink)

We contest each other's memory claims all the time. I am concerned with how the contesting of memory claims and narratives may be an integral part of many abusive situations.

Blackmore and Rose reported an experiment designed to examine the operation of psi when reality and imagination were confused. The original experiment used a situation in which participants were encouraged to generate false memories of common household objects. The topic of false memory is highly relevant to parapsychologists and psychical researchers in two ways. First, it may be the case that psi lurks in this borderline between reality and imagination. There are abundant examples of phenomena that appear to utilise (...) such a confusion: spontaneous cases, which often involve “realistic dreams,” lucid dreams, false awakenings, hypnagogic images, waking imagery, and sleep paralysis; and states in which reality and imagination are often confused. The occult traditions, for example, shamanistic traditions that entail the use of drugs and sensory deprivation to induce altered states of consciousness in which imagery is enhanced, and experienced journeys are interpreted as real excursions. Finally, laboratory psi techniques, for example, the use of hypnosis or encouraging imagery to arise unbidden, can also be thought of as utilising this kind of confusion. Alternatively, confusions between reality and imagination can represent a serious problem for parapsychologists and psychical researchers who often have to rely on eyewitness reports of spontaneous, ostensibly psychic, or paranormal events.

Maswood and Rajaram examine the transmission of false memories across small and larger networks. While the spread of false memories is not inherently beneficial, Maswood & Rajaram argued that a better understanding of the formation and propagation of false memories has practical and societal implications. For example, by better understanding how false memories transmit across groups, we might be better equipped to prevent detrimental behaviors that arise as a result of “fake news.”.

Building on Dor’s theory of language as a social technology for the instruction of imagination, I suggest that autobiographical memory evolved culturally as a response to the problems of false memory and deliberate deceit that were introduced by that technology. I propose that sapiens’ linguistic communication about past and future events initially occurred in small groups, and this helped to correct individual memory defects. However, when human groups grew in size and became more socially differentiated, and movement (...) between groups prevented story-verification, misattributions of events became more common. In such conditions individuals with better autobiographical memory had an advantage because they could evaluate their own contents and sources of information, as well as that of others, more accurately; this not only benefitted them directly, but also improved their reliability as social partners. Autobiographical memory thus evolved in the context of human linguistic communication through selection for communicative reliability. However, the advantages of imagination, which enables forward-planning and decision-Making, meant that memory distortions, although controlled and moderated by autobiographical memory, could not be totally eradicated. This may have driven the evolution of additional forms of memory control involving social and linguistic norms. I interpret the language and the social norms of the Pirahã as the outcome of the cultural-evolutionary control of memory distortions. Some ways of testing aspects of this proposal are outlined.

One challenge to creating realistic cognitive models of memory is the inability to account for the vast common–sense knowledge of human participants. Large computational knowledge bases such as WordNet and DBpedia may offer a solution to this problem but may pose other challenges. This paper explores some of these difficulties through a semantic network spreading activation model of the Deese–Roediger–McDermott false memory task. In three experiments, we show that these knowledge bases only capture a subset of human associations, (...) while irrelevant information introduces noise and makes efficient modeling difficult. We conclude that the contents of these knowledge bases must be augmented and, more important, that the algorithms must be refined and optimized, before large knowledge bases can be widely used for cognitive modeling.

Pezdek and Lam [Pezdek, K. & Lam, S. . What research paradigms have cognitive psychologists used to study “False memory,” and what are the implications of these choices? Consciousness and Cognition] claim that the majority of research into false memories has been misguided. Specifically, they charge that false memory scientists have been misusing the term “false memory,” relying on the wrong methodologies to study false memories, and misapplying false memory research to real world situations. We review (...) each of these claims and highlight the problems with them. We conclude that several types of false memory research have advanced our knowledge of autobiographical and recovered memories, and that future research will continue to make significant contributions to how we understand memory and memory errors.

ABSTRACTThe negativity bias is the tendency for individuals to give greater weight, and often exhibit more rapid and extreme responses, to negative than positive information. Using the Deese-Roediger-McDermott illusory memory paradigm, the current study sought to examine how the negativity bias might affect both correct recognition for negative and positive words and false recognition for associated critical lures, as well as how trait neuroticism might moderate these effects. In two experiments, participants studied lists of words composed of semantic associates (...) of an unpresented word. Half of the lists were comprised of positive words and half were comprised of negative words. As expected, individuals remembered negative list words better than positive list words, consistent with a negativity bias in correct recognition. When tested immediately, individuals also exhibited greater false memory for negative versus positive critical lures. When tested after a 24-hr delay... (shrink)

Previous research shows that manipulations (e.g. levels-of-processing) that facilitate true memory often increase susceptibility to false memory. An exception is the generation effect. Using the Deese/Roediger–McDermott (DRM) paradigm, Soraci et al. found that generating rather than reading list items led to an increase in true but not false memories. They argued that generation led to enhanced item-distinctiveness that drove down false memory production. In the current study, we investigated the effects of generative processing on valenced stimuli and (...) after a delayed retention interval to examine factors that may lead to a generation effect that increases false memories. At the immediate test, false recognition rates for both negative and neutral valanced critical lures were similar across read and generate conditions. However, after a one-week delay, we saw a valence differentiation, with a generation effect for false recognition but only for negative stimuli. The roles of item-specific and relational processing during encoding and their interaction with long-term retention are discussed. (shrink)

Emotional memories are vivid and lasting but not necessarily accurate. Under some conditions, emotion even increases people’s susceptibility to false memories. This review addresses when and why emotion leaves people vulnerable to misremembering events. Recent research suggests that pregoal emotions—those experienced before goal attainment or failure —narrow the scope of people’s attention to information that is central to their goals. This narrow focus can impair memory for peripheral details, leaving people vulnerable to misinformation concerning those details. In contrast, postgoal (...) emotions—those experienced after goal attainment or failure —broaden the scope of attention leaving people more resistant to misinformation. Implications for legal contexts, such as emotion-related errors in eyewitness testimony, are discussed. (shrink)

McKay & Dennett (M&D) suggest that some positive illusions are adaptive. But there is a bidirectional link between memory and positive illusions: Biased autobiographical memories filter incoming information, and self-enhancing information is preferentially attended and used to update memory. Extending M&D's approach, I ask if certain false memories might be adaptive, defending a broad view of the psychosocial functions of remembering.

Recent models of cognition in Posttraumatic Stress Disorder predict that trauma-related, but not neutral, processing should be differentially affected in these patients, compared to trauma-exposed controls. This study compared a group of 50 patients with PTSD related to the war in Bosnia and a group of 50 controls without PTSD but exposed to trauma from the war, using the DRM method to induce false memories for war-related and neutral critical lures. While the groups were equally susceptible to neutral critical lures, (...) the PTSD group mistakenly recalled more war-related lures. Both false and correct recall were related more to depression than to self-rated trauma. Implications for accounts of false memories in terms of source-monitoring are discussed. (shrink)

What are the roles of semantic and pragmatic processes in the interpretation of sentences in context? And how do we attain such interpretations when sentences are deemed indeterminate? Consider a sentence such as “Lisa began the book” which does not overtly express the activity that Lisa began doing with the book. Although it is believed that individuals compute a specified event to enrich the sentential representation – yielding, e.g., “began [reading] the book” – there is no evidence that a default (...) event meaning is attained. Moreover, if indeterminate sentences are enriched, it is not clear where the information required to generate enriched interpretations come from. Experiment 1 showed that, in isolation, there is no default interpretation for indeterminate sentences. The experiment also showed that biasing contexts constrain event interpretations and improve plausibility judgments, suggesting that event representations for indeterminate sentences are generated by context. In Experiment 2, participants heard biasing discourse contexts and later falsely recognized foil sentences containing the biased events at the same proportion and with the same confidence as the original indeterminate sentence. We suggest that indeterminate sentences trigger event-enriching inferences but only in sufficiently constraining contexts. We also suggest that indeterminate sentences create two memory traces, one for the proposition consistent with the denotational, compositional meaning, and another for the proposition that is enriched pragmatically over time.

The question whether memory aberrations in posttraumatic stress disorder also manifest as an increased production of false memories is important for both theoretical and practical reasons, but is yet unsolved. Therefore, for the present study we investigated veridical and false recognition in PTSD with a new scenic variant of the Deese–Roediger–McDermott paradigm, which was administered to traumatized individuals with PTSD , traumatized individuals without PTSD , and non-traumatized controls . The PTSD group neither produced higher rates of false memories (...) nor expressed more confidence in errors, but did show inferior memory sensitivity. Whereas depressive symptoms did not correlate with veridical nor false recognition, state dissociation was positively associated with false memories. (shrink)

Findings from the cognitive sciences suggest that the cognitive mechanisms responsible for some memory errors are adaptive, bringing benefits to the organism. In this paper we argue that the same cognitive mechanisms also bring a suite of significant epistemic benefits, increasing the chance of an agent obtaining epistemic goods like true belief and knowledge. This result provides a significant challenge to the folk conception of memory beliefs that are false, according to which they are a sign of cognitive (...) frailty, indicating that a person is less reliable than others or their former self. Evidence of memory errors can undermine a person’s view of themselves as a competent epistemic agent, but we show that false memory beliefs can be the result of the ordinary operation of cognitive mechanisms found across the species, which bring substantial epistemic benefits. This challenge to the folk conception is not adequately captured by existing epistemological theories. However, it can be captured by the notion of epistemic innocence, which has previously been deployed to highlight how beliefs which have epistemic costs can also bring significant epistemic benefits. We therefore argue that the notion of epistemic innocence should be expanded so that it applies not just to beliefs but also to cognitive mechanisms. (shrink)

Child abuse is surely the most agonizing psychological issue of our time. We decry the tendency to polarize around the either-or dichotomy of "recovered versus false memories," when both are likely to occur. Memory researchers seem to generalize from the mild, one-shot stressors of the laboratory to the severe repeated traumas reported by abused populations, an inferential leap that is scientifically dubious. Naturalistic studies show some post-traumatic memory impairment ; dissociativity, such as emotional numbing, detachment, and the like; (...) but also increased suggestibility . About 20% of the normal population is highly suggestible, and in these individuals it is trivially easy to show suggested amnesia, detachment, perceptual blocking, etc., as well as to suggest dramatically false memories. It is therefore vital to assess suggestibility and dissociativity in traumatized populations. Adult survivors of abuse may show both more false "memories" and more "false forgetting" than the normal population. (shrink)

In response to the failure of Zeelenberg, Plomp, and Raaijmakers to replicate the results of Seamon, Luo, and Gallo regarding their purported finding of a reliable false memory effect in the absence of memory for the list items, Gallo and Seamon report a new experiment that they claim shows that conscious activation of a related lure during study is not necessary for its subsequent recognition. We critically evaluate their conclusion and argue that the evidence clearly shows that false (...) recognition is critically dependent on the conscious recollection of one or more of the list items. Thus, this as well as the previous experiments show no evidence for nonconscious processes in producing false memories. (shrink)

Constructivists about memory argue that memory is a capacity for building representations of past events from a generalized information store. The view is motivated by the memory errors discovered in cognitive psychology. Little has been known about the neural mechanisms by which false memories are produced. Recently, using a method I call the Optogenetic False Memory Technique, neuroscientists have created false memories in mice. In this paper, I examine how Constructivism fares in light of O-FaMe results. (...) My aims are two-fold. First, I argue that errors found in O-FaMe and cognitive psychology are similar behaviorally. Second, Constructivists should be able to explain the former since they purport to explain the latter, but they cannot. I conclude that O-FaMe studies reveal details about the mechanism by which false memories are produced that are incompatible with the explanatory approach to false memories favored by Constructivism.
