Dissociation Related to Subjective Memory Fragmentation and Intrusions but Not to Objective Memory Disturbances
ARTICLE IN PRESS Journal of Behavior Therapy and Experimental Psychiatry 36 (2005) 43–59 www.elsevier.com/locate/jbtep Dissociation related to subjective memory fragmentation and intrusions but not to objective memory disturbances Merel Kindta,Ã, Marcel Van den Houtb, Nicole Buckb aDepartment of Clinical Psychology, University of Amsterdam, Roetersstraat 15, 1018 WB Amsterdam, The Netherlands bDepartment of Medical, Clinical and Experimental Psychology, Maastricht University, The Netherlands Abstract The present study was a replication of Kindt and Van den Hout (Behaviour Research and Therapy 41 (2003) 167) with several methodological adaptations. Two experiments were designed to test whether state dissociation is related to objective memory disturbances, or whether dissociation is confined to the realm of subjective experience. High trait dissociative participants (Nexp:1 ¼ 25; Nexp:2 ¼ 25) and low trait dissociative participants (Nexp:1 ¼ 25; Nexp:2 ¼ 25) were selected from normal samples (Nexp:1 ¼ 372; Nexp:2 ¼ 341) on basis of scores on the Dissociative Experience Scale (DES). Participants watched an extremely aversive film, after which state dissociation was measured by the Peri-traumatic Dissociative Experience Questionnaire (PDEQ). Memory disturbances were assessed 4h later (Exp. 1) or 1 week later (Exp. 2). Objective memory disturbances were assessed by a sequential memory task, items tapping perceptual representations (Exp. 1), or an open question with respect to the remembrance of the film (Exp. 2). Subjective memory disturbances were measured by means of visual analogue scales assessing fragmentation and intrusions. The two experiments provided a fairly exact replication of an earlier experiment (Behaviour Research and Therapy 41 (2003) ÃCorresponding author.

Memory-Modulation: Self-Improvement Or Self-Depletion?
HYPOTHESIS AND THEORY published: 05 April 2018 doi: 10.3389/fpsyg.2018.00469 Memory-Modulation: Self-Improvement or Self-Depletion? Andrea Lavazza* Neuroethics, Centro Universitario Internazionale, Arezzo, Italy Autobiographical memory is fundamental to the process of self-construction. Therefore, the possibility of modifying autobiographical memories, in particular with memory-modulation and memory-erasing, is a very important topic both from the theoretical and from the practical point of view. The aim of this paper is to illustrate the state of the art of some of the most promising areas of memory-modulation and memory-erasing, considering how they can affect the self and the overall balance of the “self and autobiographical memory” system. Indeed, different conceptualizations of the self and of personal identity in relation to autobiographical memory are what makes memory-modulation and memory-erasing more or less desirable. Because of the current limitations (both practical and ethical) to interventions on memory, I can Edited by: only sketch some hypotheses.

Investigating the Roles of Memory and Metamemory in Trauma-Related Outcomes
ABSTRACT A PTSD ANALOGUE STUDY: INVESTIGATING THE ROLES OF MEMORY AND METAMEMORY IN TRAUMA-RELATED OUTCOMES Ban Hong (Phylice) Lim, Ph.D. Department of Psychology Northern Illinois University, 2016 Michelle M. Lilly, Director Trauma survivors who develop posttraumatic stress disorder (PTSD) often display symptoms of memory fragmentation such as an impaired ability to recall trauma memories. These observations are consistent with prominent theories of PTSD, which consider memory fragmentation as a central feature of PTSD. Correspondingly, most empirically supported interventions for PTSD focus on addressing dysfunctional thoughts and behaviors and integrating fragmented memories of the event. More recently, this assumption has been challenged by research indicating that metamemory – one’s subjective beliefs about one’s memory functioning and quality – may partially account for reported memory fragmentation among individuals with PTSD. Memory underconfidence, regardless of whether or not it is founded or wholly accurate, may lead to feelings of anxiety, especially in the process of recalling and making sense of one’s trauma memory. Despite the intertwined nature of their relationship, the association between memory and metamemory has been understudied in the trauma literature. This dissertation investigated whether PTSD is a disorder of memory fragmentation, perceived memory fragmentation, or both by examining the association between memory and metamemory. A trauma analogue between-subjects experimental design was employed. Eighty- four healthy participants were randomly assigned to receive either positive feedback or negative feedback after completing a standardized memory assessment. Despite the use of randomization, the manipulation groups systematically differed on both baseline memory ability and baseline memory confidence. Contrary to the first hypothesis, after controlling for the effect of baseline metamemory beliefs, the groups did not differ on their recall task performance, F(1,80) = .34, p = .56. -

Phenomenology of Intrusive Trauma Memory in Psychosis and Its
Phenomenology of Intrusive Trauma Memory in Psychosis and its Relationship with Hallucinations and Persecutory Beliefs Sophie Marsh-Picksley D.Clin.Psy. thesis (Volume 1), 2016 University College London 1 UCL Doctorate in Clinical Psychology Thesis declaration form I confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signature: Name: Sophie Marsh-Picksley Date: 15th December 2016 2 Overview This thesis is presented in three parts, and is focused on developing the theoretical understanding of the role of trauma memory in psychosis. The systematic literature review investigates the relationship between psychosis symptom severity and re-experiencing of traumatic memories. 13 studies published since 1980 were identified as meeting the review criteria. Overall, findings suggest that people with more severe hallucinations and paranoia experiences report more re-experiencing of traumatic memories. However, this relationship was not seen when looking at more global symptoms of psychosis. The role of trauma memory in the development and maintenance of psychosis therefore warrants further investigation. The empirical paper (a joint project with Carr (2016), “Developing a brief trauma screening tool for use in psychosis”) explores the phenomenology of intrusive trauma memory in psychosis and investigates its relationship to hallucinations and persecutory beliefs. In line with theoretical accounts (Steel et al, 2005), it was hypothesised that increased memory fragmentation would be associated with more severe hallucinations. Twenty participants described an intrusive trauma memory and its phenomenological characteristics. Findings indicated that subjective fragmentation of intrusive memories was associated with more severe hallucinations but not persecutory beliefs, although the relationship between the two ratings of objective memory fragmentation and hallucinations were equivocal, with a negative correlation for one rating and no relationship for the other. -
Emotion and Memory: Children’S Long-Term Remembering, Forgetting, and Suggestibility
Journal of Experimental Child Psychology 72, 235–270 (1999) Article ID jecp.1999.2491, available online at http://www.idealibrary.com on Emotion and Memory: Children’s Long-Term Remembering, Forgetting, and Suggestibility Jodi A. Quas University of California, Berkeley Gail S. Goodman University of California, Davis Sue Bidrose, Margaret-Ellen Pipe, and Susan Craw University of Otago, Dunedin, New Zealand and Deborah S. Ablin University of California, Davis Children’s memories for an experienced and a never-experienced medical procedure were examined. Three- to 13-year-olds were questioned about a voiding cystourethrogram fluoros- copy (VCUG) they endured between 2 and 6 years of age. Children 4 years or older at VCUG were more accurate than children younger than 4 at VCUG. Longer delays were associated with providing fewer units of correct information but not with more inaccuracies. Parental avoidant attachment style was related to increased errors in children’s VCUG memory. Children were more likely to assent to the false medical procedure when it was alluded to briefly than when described in detail, and false assents were related to fewer “do-not-know” responses about the VCUG. Results have implications for childhood amnesia, stress and memory, individual differences, and eyewitness testimony. © 1999 Academic Press Key Words: children’s memory; infantile amnesia; emotion; attachment; suggestibility; eyewitness testimony.

Memories of Fear How the Brain Stores and Retrieves Physiologic States, Feelings, Behaviors and Thoughts from Traumatic Events Bruce D
Memories of Fear How the Brain Stores and Retrieves Physiologic States, Feelings, Behaviors and Thoughts from Traumatic Events Bruce D. Perry, M.D., Ph.D. The Child Trauma Academy www.ChildTrauma.org This is an Academy version of a chapter originally appearing in “Splintered Reflections: Images of the Body in Trauma” (Edited by J. Goodwin and R. Attias) Basic Books (1999). Memory -- the capacity to bring elements of an experience from one moment in time to another is the unique property of life forms. This remarkable property - the carrying of information across time - is the foundation of every biological process from reproduction to gene expression to cell division – from receptor-mediated communication to the development of more complex physiological systems (including neurodevelopment). To some degree, all of the organ systems in the human body have “memory.” This ability to carry elements of previous experience forward in time is the basis of the immune, the neuromuscular, and neuroendocrine systems. Through complex physiological processes, elements of experience can even be carried across generations. Elements of the collective experience of the species are reflected in the genome, while the experience of the individual is reflected in the expression of that genome. No other biological system has developed more sophisticated capacity to make and store internal representations of the external world – and the internal world – than the human central nervous system, the human brain. All nerve cells ‘store’ information in a fashion that is contingent upon previous patterns of activity (see Singer, 1995; Thoenen, 1995). Neurons are specifically designed to modify in response to external cues (e.g., neurohormones, neurotransmitters, neurotrophic factors; Lauder, 1988). -
