Abstract
OBJECTIVES The role of self in veridical memory has been extensively studied, but what is the role of self in false memory development across the life span? The current study examined the impact of self-reference on associative false memory in children, younger adults, and older adults, and further investigated possible mechanisms concerning how self-reference might impact false memory in different age groups. METHOD Combining a self-reference manipulation with the Deese/Roediger-McDermott (DRM) paradigm, children, younger adults and older adults encoded DRM word lists as paired with their own name, another person's name, or a red square. Later their true and false recognition memory as well as recollection and familiarity were measured. RESULTS A self-enhanced false memory effect was found in all age groups. That is, participants generated more false memories in the self-reference condition relative to the other-reference and neutral conditions. Furthermore, when examining its underlying memory mechanisms, we found that self-reference mainly increased false recollection in younger adults but facilitated familiarity of critical lures in older adults. DISCUSSION Although self-reference increases false memory in both younger and older adults, the underlying mechanisms are different in that older adults have more self-relevant false familiarity while younger adults generate more self-relevant phantom recollection. The current study also has implications for eyewitness reports, suggesting that the self-relevance of memory may be one relevant factor to consider when evaluating potential risk factors of false memory.

Abstract
The present review is intended as an overview of our current understanding of how children's individual characteristics, in terms of demographic, cognitive, and psycho-social variables, may influence their susceptibility to suggestion. The goals are to revisit conceptual models of the mechanisms of suggestibility, to provide an updated practical guide for practitioners, and to make recommendations for future research. Results suggest that children with intellectual impairment and those with nascent language skills may be particularly vulnerable to suggestion. Further, memory for separate events, theory of mind, executive function, temperament, and social competence may not be related to suggestibility, whereas additional work is needed to clarify the potential contributions of knowledge, stress, mental health, parental elaborative style, and adverse experiences/maltreatment to children's suggestibility.

Abstract
This study investigated age differences in false memory for visual scenes and the effect of immediate recall on subsequent recognition. Eighty children (7–9 years), 74 adolescents (14–16 years), 92 young adults (19–26 years) and 82 older adults (50–80 years) studied four visual scenes and then took a recognition test after either a free-recall task or a filler task. Results showed an age-related decline in false recognition for visual scenes, but this trend was eliminated when participants were asked to free-recall before recognition. Prior recall decreased false recognition in children, but increased false recognition in older adults. Across the lifespan, adolescents had the loosest criterion, children had the lowest false recall, and prior recall increased true recognition in older adults.

Abstract
Suggestibility is regarded as a major issue when children testify in court. Many legal professionals and memory researchers view children as inferior witnesses. Although differences in suggestibility exist between children and adults, they are much more complex than is usually assumed. We show that under certain conditions, adults are more susceptible than children to suggestion and false memories. We provide evidence that age-related shifts in suggestibility and false memory appear contingent on how quickly and automatically children and adults make associations when experiencing events. Specifically, when confronted with suggestive information about a related but nonexperienced detail, adults more frequently automatically generate links between items experienced and those already in memory, making them more susceptible to suggestion than children.

Abstract
We report the 1st example of a true complementarity effect in memory development-a situation in which memory for the same event simultaneously becomes more and less accurate between early childhood and adulthood. We investigated this paradoxical effect because fuzzy-trace theory predicts that it can occur in paradigms that produce developmental reversals in false memory, which are circumstances in which adults are more likely than children to remember new events as old. The complementarity prediction is this: If subjects separately judge whether those same events are new but similar to old ones, adults will be more accurate than children, even though adults are less accurate when they judge whether the items are old. We report 4 experiments in which children (6- and 10-year-olds), adolescents (14-year-olds), and adults encoded the modal developmental reversal materials: Deese-Roediger-McDermott lists. Then, they responded to memory tests on which half the subjects judged whether test items were old and half judged whether the same items were new-similar. The paradoxical complementarity effect was detected in all experiments: The tendency to falsely remember new-similar items as being old increased with development, but so did the tendency to correctly remember them as being new-similar.

Abstract
Among many legal professionals and memory researchers there exists the assumption that susceptibility to false memory decreases with age. In 4 misinformation experiments, we show that under conditions that focus on the meaning of experiences, children are not always the most susceptible to suggestion-induced false memories. We begin by presenting a short overview of previous developmental false memory studies, the majority of which have found that the susceptibility to misinformation decreases with age. In Experiment 1, 6/7-year-olds, 11/12-year-olds, and adults received a video and were confronted with misinformation about related but nonpresented details. Older children and adults had higher misinformation acceptance rates than younger children. In Experiment 2, we replicated this finding adding a younger child group (4/6-year-olds). In Experiments 3 and 4, we used new material and again found that susceptibility to misinformation increased with age. Together, these experiments show that children's memory accuracy is not necessarily inferior to that of adults.'

Abstract
Fuzzy-trace theory posits independent verbatim and gist memory processes, a distinction that has implications for such applied topics as eyewitness testimony. This distinction between precise, literal verbatim memory and meaning-based, intuitive gist accounts for memory paradoxes including dissociations between true and false memory, false memories outlasting true memories, and developmental increases in false memory. We provide an overview of fuzzy-trace theory, and, using mathematical modeling, also present results demonstrating verbatim and gist memory in true and false recognition of narrative sentences and inferences. Results supported fuzzy-trace theory's dual-process view of memory: verbatim memory was relied on to reject meaning-consistent, but unpresented, sentences (via recollection rejection). However, verbatim memory was often not retrieved, and gist memory supported acceptance of these sentences (via similarity judgment and phantom recollection). Thus, mathematical models of words can be extended to explain memory for complex stimuli, such as narratives, the kind of memory interrogated in law.

Abstract
Fuzzy-trace theory (FTT) emphasizes the use of core theoretical principles, such as the verbatim-gist distinction, to predict new findings about cognitive development that are counterintuitive from the perspective of other theories or of common-sense. To the extent that such predictions are confirmed, the range of phenomena that are explained expands without increasing the complexity of the theory's assumptions. We examine research on recent examples of such predictions during four epochs of cognitive development: childhood, adolescence, young adulthood, and late adulthood. During the first two, the featured predictions are surprising developmental reversals in false memory (childhood) and in risky decision making (adolescence). During young adulthood, FTT predicts that a retrieval operation that figures centrally in dual-process theories of memory, recollection, is bivariate rather than univariate. During the late adulthood, FTT identifies a retrieval operation, reconstruction, that has been omitted from current theories of normal memory declines in aging and pathological declines in dementia. The theory predicts that reconstruction is a major factor in such declines and that it is able to forecast future dementia.

Abstract
The current study investigated the effects of misinformation on children's memory reports after practice with the logic-of-opposition instruction at time of test. Four- and 6-year-old children participated in a play event in Session 1. During a two-week delay, parents presented their children with either misinformation or correct information about the play event. Prior to a memory interview in Session 2, some misled children were given a developmentally appropriate logic-of-opposition instruction to not report information provided by their parents. Results indicated that children were misled by the incorrect information, but that the logic-of-opposition instruction aided in the children's retrieval of the original memory, particularly for the 6-year-olds. Implications of the results for memory malleability and social demand effects in children are discussed.

Abstract
The concept of spreading activation describes how retrieval of one memory cues retrieval of other memories that are associated with it. This study explored spreading activation in 6-, 12-, and 18-month-old infants. Infants (n = 144) learned two tasks within the same experimental session; one task, deferred imitation (DI), is typically remembered longer than the other task, visual recognition memory (VRM). At all ages, retrieval of the DI memory facilitated retrieval of the VRM memory, but the conditions under which this spreading activation occurred changed as a function of age. The implications of these findings are discussed in relation to the development of mnemonic networks during infancy and the value of studying infants for our understanding of memory more generally.

Abstract
A hoary assumption of the law is that children are more prone to false-memory reports than adults, and hence, their testimony is less reliable than adults'. Since the 1980s, that assumption has been buttressed by numerous studies that detected declines in false memory between early childhood and young adulthood under controlled conditions. Fuzzy-trace theory predicted reversals of this standard developmental pattern in circumstances that are directly relevant to testimony because they involve using the gist of experience to remember events. That prediction has been investigated during the past decade, and a large number of experiments have been published in which false memories have indeed been found to increase between early childhood and young adulthood. Further, experimentation has tied age increases in false memory to improvements in children's memory for semantic gist. According to current scientific evidence, the principle that children's testimony is necessarily more infected with false memories than adults' and that, other things being equal, juries should regard adult's testimony as necessarily more faithful to actual events is untenable.

Abstract
Research on factors that can affect the accuracy of children's autobiographical remembering has important implications for understanding the abilities of young witnesses to provide legal testimony. In this article, we review our own recent research on one factor that has much potential to induce errors in children's event recall, namely natural memory sharing conversations with peers and parents. Our studies provide compelling evidence that not only can the content of conversations about the past intrude into later memory but that such exchanges can prompt the generation of entirely false narratives that are more detailed than true accounts of experienced events. Further, our work show that deeper and more creative participation in memory sharing dialogues can boost the damaging effects of conversationally conveyed misinformation. Implications of this collection of findings for children's testimony are discussed.

Abstract
Three experiments assessed the relationships between false memories of words and their degree of connectedness within individual semantic networks. In the first two experiments, participants studied associated word lists (e.g., hot, winter, ice), completed a recognition test that included related nonstudied words (e.g., cold, snow), and then rated the semantic relatedness of all word pairs including studied and nonstudied words. In the third experiment, the task order was reversed; participants completed pairwise ratings and then, two weeks later, completed the false memory task. The relatedness ratings were analysed using the Pathfinder scaling algorithm. In all experiments, items that an individual falsely recognized had higher semantic Pathfinder node densities than those items correctly rejected.

Abstract
When two or more people witness an event together, the event report from one person can influence others' reports. In the current study we examined the role of age and motivational factors on peer influence regarding event reports in adolescents and young adults. Participants (N=249) watched a short video of a robbery then answered questions with no co-witness information or with information believed to be from a co-witness. Public and private response conditions were included to explore motivations for peer influence. Co-witness information influenced participants' responses, although the effect was equally strong in the private and the public co-witness conditions. Peer influence on event reports was steady across a large age range (11- to 25-year-olds).

Abstract
In the study of false memory, developmental research on the Deese-Roediger-McDermott (DRM) illusion has played a pivotal role in theory evaluation and forensic application. The extensive developmental DRM literature (55 experiments published in English-language journals) provided the first clear evidence that false memories can increase dramatically from early childhood onward, whereas traditional ideas about cognitive development predict steady declines. Similar increases have recently been reported in false memory for complex, realistic life events, using forensically oriented paradigms. Age improvements in the ability to connect meaning across words have been found to be necessary and sufficient for developmental increases in the DRM illusion. When the data of developmental DRM studies are combined with parallel findings from forensically oriented paradigms, the result is an existence proof that a principle used by the law to evaluate children's evidence is mistaken. According to that principle, children's versions of events are always more likely to be infected with false memories than those of adults, and hence, juries should give more weight to adults' versions of events.

Abstract
Previous research has shown that overhearing an errant rumor--either from an adult or from peers--about an earlier experience can lead children to make detailed false reports. This study investigates the extent to which such accounts are driven by changes in children's memory representations or merely social demands that encourage the reporting of rumored information. This was accomplished by (a) using a warning manipulation that eliminated social pressures to report an earlier heard rumor and (b) examining the qualitative characteristics of children's false narratives of a rumored-but-nonexperienced event. Findings indicated that overheard rumors can induce sensory and contextual characteristics in memory that can lead children to develop genuine false beliefs in seeing rumored-but-nonexperienced occurrences. Such constructive tendencies were especially likely among 3- and 4-year-olds (relative to 5- and 6-year-olds) and when rumors were picked up from peers during natural social interactions (relative to when they were planted by an adult).

Abstract
In two experiments, we examined whether post-event information (PEI) about true and false events persisted in children's reports after approximately 1 year. In Experiment 1, 4- to 6-year-olds were given PEI and then were given memory tests 2 weeks and 15 months later. Although PEI appeared in free recall at the initial testing, it decreased substantially by the long-term test. In contrast, on recognition tasks the children showed facilitation and misinformation effects at initial and follow-up tests. Experiment 2 replicated lasting misinformation and facilitation effects in recognition memory among 4- to 9-year-olds who were tested after 1-week and 10-month delays. We conclude that true and false reminders about an experienced event continue to affect children's memory approximately 1 year later.

Abstract
Knowing how to identify events that we never experienced is an important skill: This ability enables us to reject such events as part of our past and thus reduces the risk of creating false memories. Recent research highlights the involvement of metamemory processes in this domain. I review empirical evidence pertaining to the functioning and development of the memorability-based strategy, a specific mechanism rooted in metamemory. The substantial development of this mechanism during childhood can provide an account for children's vulnerability to false-memory formation.

Abstract
The present study investigated developmental differences in the effects of repeated interviews and interviewer bias on children's memory and suggestibility. Three- and 5-year-olds were singly or repeatedly interviewed about a play event by a highly biased or control interviewer. Children interviewed once by the biased interviewer after a long delay made the most errors. Children interviewed repeatedly, regardless of interviewer bias, were more accurate and less likely to falsely claim that they played with a man. In free recall, among children questioned once after a long delay by the biased interviewer, 5-year-olds were more likely than were 3-year-olds to claim falsely that they played with a man. However, in response to direct questions, 3-year-olds were more easily manipulated into implying that they played with him. Findings suggest that interviewer bias is particularly problematic when children's memory has weakened. In contrast, repeated interviews that occur a short time after a to-be-remembered event do not necessarily increase children's errors, even when interviews include misleading questions and interviewer bias. Implications for developmental differences in memory and suggestibility are discussed.

Abstract
We examine eight unwarranted assumptions made by expert witnesses, forensic interviewers, and legal scholars about the reliability of children's eyewitness reports. The first four assumptions modify some central beliefs about the nature of suggestive interviews, age-related differences in resistance to suggestion, and thresholds necessary to produce tainted reports. The fifth unwarranted assumption involves the influence of both individual and interviewer factors in determining children's suggestibility. The sixth unwarranted assumption concerns the claim that suggested reports are detectable. The seventh unwarranted assumption concerns new findings about how children deny, disclose, and/or recant their abuse. Finally, we examine unwarranted statements about the value of science to the forensic arena. It is important not only for researchers but also expert witnesses and court-appointed psychologists to be aware of these unwarranted assumptions.
