Abstract
Imagination inflation happens when a person's subjective confidence that an event has occurred increases after they imagine it occurring. In this project, our primary aim is to test whether memory distrust is related to the imagination inflation effect in people who are aware of the discrepancies between their own memories and what they have imagined. Our secondary purpose is to investigate whether the influence of memory distrust on imagination inflation is moderated by traits that are described as disengagement from reality and to test whether memory distrust mediates the relationship between self-esteem and imagination inflation. In a three-step procedure, participants (N = 300) will assess their confidence that a list of childhood events happened to them; then, they will imagine three of these events and reassess their confidence. Half of the participants will undergo a memory distrust induction procedure. In order to sensitize participants to discrepancies, some of them will be given cues about the source and/or perspective of the imagined events.

Abstract
Trauma-focused imagery-based interventions, such as Imagery Rescripting (ImRs) and Imaginal Exposure (ImE), are effective in reducing involuntary re-experiencing in PTSD. However, it has been suggested that they may impair voluntary memory. This study investigates whether ImRs and ImE distort voluntary memory of an analogue trauma. We presented a trauma film to N = 120 healthy participants (Session 1) and randomly allocated them to one of two intervention conditions (receiving one session of ImRs or ImE) or to a no-intervention control condition (NIC) afterwards (Session 2). Voluntary memory was assessed using a free recall (Sessions 2 and 3), and a cued recall as well as a recognition task (both Sessions 3 and 4). The ImRs and ImE groups did not differ from NIC in the cued recall task and the recognition task. However, ImE (compared to ImRs and NIC) led to an increase in correct reported details in the free recall. In sum, the current findings do not suggest that ImRs or ImE impair voluntary memory.

Abstract
Psychological interventions often use guided discovery and other techniques for diagnostic exploration and intervention planning. This way, memories may arise in the person, which may be true or false. False memories of earlier events can be harmful and result in real suffering, similar to actual traumatic memories. Based on cognitive psychological and psycho-traumatological findings, there is pronounced dissent in the academic disciplines regarding the conceptualization, relevance and research of false memories. This review contributes to the basic question of how often false beliefs and false memories may be induced within the frame of different interactional techniques. A systematic review has been conducted of 59 articles from (quasi-)experimental studies and two qualitative sources from 30 data bases. Three main methods of memory induction provide the basis for reporting: imagination inflation, false feedback, and memory implantation. Due to the conceptual and methodological diversity of the studies, the results appear to be heterogeneous. Free and guided imagery, as well as suggestive statements, could induce false beliefs or false memories in, on average, 20%-50% of the participants who underwent experimental manipulation concerning false past events. A false belief induction may occur after dream interpretation or hypnosis in more than 50% of participants. Personalized suggestion is more effective in inducing memory than the general plausibility of the suggested events. Further research questions are which therapeutic actions seem appropriate in cases of harmful false memories. This depends not only on whether there are veridical elements in the false memory but also on the quality and meaning of the memory for the person's life and ability to cope with burdens.

Abstract
Decades of research show that people are susceptible to developing false memories. But if they do so in one task, are they likely to do so in a different one? The answer: "No". In the current research, a large number of participants took part in three well-established false memory paradigms (a misinformation task, the Deese-Roediger-McDermott [DRM] list learning paradigm, and an imagination inflation exercise) as well as completed several individual difference measures. Results indicate that many correlations between false memory variables in all three inter-paradigm comparisons are null, though some small, positive, significant correlations emerged. Moreover, very few individual difference variables significantly correlated with false memories, and any significant correlations were rather small. It seems likely, therefore, that there is no false memory "trait". In other words, no one type of person seems especially prone, or especially resilient, to the ubiquity of memory distortion.

Abstract
Research has demonstrated that merely imagining an autobiographical event can bring about false memories for that event. One explanation for this is that imagination leads to the creation and incorporation of visual-imagistic information into the event representation. This idea was tested in two experiments in which visual-imagery processing was disrupted by the use of Dynamic Visual Noise (DVN). In Experiment 1, autobiographical memories that were rated as "known" and lacking in event detail were subsequently rated as more "remembered" following imagination. In Experiment 2, imagination led to improbable autobiographical events being rated as more believable and vivid. In both experiments, interfering with imagery processing by DVN reduced these effects. It was concluded that visual-imagistic processing plays an important role in altering the mnemonic status of autobiographical representations.

Abstract
In the present study of false memory, subjects completed the Prevalence of Visual Imagery Test (PVIT), the Vividness of Visual Imagery Questionnaire (VVIQ), and the Curious Experiences Survey (CES); then, after generating visual images, viewing categorically related pictures, and viewing categorically related words, subjects completed forced-choice source recognition tests for whether they had “imaged” the word, the picture, or the image in a given category. Scoring higher on the CES Dissociative Amnesia/Fugue factor—controlling for the VVIQ and the PVIT—was associated both with poorer memory of the imaged source of visual images and with false memory of an imaged source for pictures. In contrast, greater image vividness on the VVIQ—controlling for CES factors—was not statistically associated with memory of an imaged source for images, pictures, or words. Greater image prevalence on the PVIT—controlling for CES factors—was associated with better memory of the imaged source of visual images and with less false memory of an imaged source for words.

Abstract
Imagination inflation is where imaginative elaboration of possible childhood experiences inflates (increases) participants' estimation that these events actually occurred, as indicated by pre- to post-manipulation ratings changes. This research primarily uses the Life Events Inventory (LEI), listing possible experiences that could have happened during childhood (Garry, Manning, Loftus, & Sherman, Psychonomic Bulletin & Review, 3, 208-214, 1996). Although imagination inflation research has spawned more than 50 investigations, no normative ratings exist on individual items contained in the LEI. To address this, we present descriptive statistics (mean, median, standard deviation, confidence interval) for 124 LEI items on occurrence (how likely is it that this experience happened to you), plausibility (how plausible is it that this event could have happened to someone), and desirability (how desirable is this experience). Occurrence and plausibility showed similar patterns of mean item ratings and were highly correlated, whereas desirability was moderately correlated with plausibility and unrelated to occurrence. These data should facilitate a more informed selection of specific LEI items to use in further research and can assist in clarifying the contributions of normative occurrence, plausibility, and desirability to imagination inflation effects.

Abstract
In the two experiments reported here the basis of the beneficial effects of generating images on false recognition errors is investigated. Acts of generating (descriptions, images, or both) were manipulated while examining the effects of the source of descriptions guiding imagery generations (participant vs peer). False recognition errors were relatively high across encoding conditions except when imagery generations were based on participants' own descriptions (Experiments 1 and 2). These differences in the acts of generating were not attributable to differences in the cohesiveness of descriptions themselves. Acts of generating led to greater "remember" responses than "know" responses only when participants were not the source of the descriptions used to generate images (Experiment 2). Results highlight the importance of examining the effects of the source of descriptions for guiding imagery (participant or peer) when testing predictions about the effects of imagery encoding on false recognition errors.

Abstract
The aim of this study was to explore whether individual differences in executive function in undergraduate students (n = 72) contribute to false recall and recognition as obtained with the Deese/Roediger-McDermott (DRM) paradigm. Participants were subjected to the DRM paradigm and also were given a test designed to assess executive function--the Random Number Generation task (RNG). A relationship was found between heightened seriation on the RNG (indicating a deficiency in the ability to inhibit cognitive schemes) and false recognition of non-presented, critical lure words in the DRM paradigm. This suggests that individual differences in executive function do occur in a healthy population and that the reconstructive activity inherent in memory depends in part on executive functioning.

Abstract
In recognition tests, items presented in unusual ways (e.g., degraded, revealed in stages, or presented as anagrams) are often judged to be old more than are intact items. This revelation effect has been observed only in episodic judgments about the occurrence or frequency of relatively recent events. The present work extends the boundary conditions of this effect. In three experiments, subjects unscrambled anagrams in the context of answering questions about their childhood (e.g., broke a dwniwo playing ball) or while answering questions pertaining to world knowledge (e.g.,fastest animal-elpraod). In each case, a revelation effect was observed: Solving an anagram increased confidence in remote autobiographical memories and in memory for world facts. These results contradict claims that the effect is an episodic memory phenomenon and challenge existing explanations of the revelation effect.
