Metacognitive processes accompanying the first stages of autobiographical retrieval in the self-memory system

ABSTRACT According to Conway’s view, Autobiographical memory (AM) construction is accompanied by control processes. These processes range from filtering out relevant memories according to the current context, to generating or elaborating appropriate retrieval cues. These processes can be conceptualised as metacognition, the ability to control and monitor cognitive processes. Experimentally, little has been carried out to support the idea that metacognition is involved in AM. To assess this, we designed a task, the Feeling of Retrieval. Participants had to predict whether cue words would facilitate AM access (i.e., fluent access cues) or not (i.e., limited access cues) in a limited time (either 1 (Exp. 2) or 2 (Exp. 1) s). Later, they retrieved memories in response to both types of cues. Results show that cues judged as fluent access led to better AM generation, as illustrated by AM retrieval latency and a subjective measure of the ease with which the AMs were retrieved. These rapid predictions may rely on epistemic feelings and / or other mnemonic cues such as a partial retrieval of information. This metacognitive access to the earliest stages of AM retrieval illustrates the ability to monitor AM processes as proposed by Conway (2005).

Remembering the good and bad and the self and others in a culturally modulated self-memory system

ABSTRACT Wang and Conway (2006, Autobiographical memory, self, and culture. In L.-G. Nilsson, & N. Ohta (Eds.), Memory and society: Psychological perspectives (pp. 9–27). Psychology Press) posit that remembering takes place in a culturally modulated self-memory system in which working self-goals are shaped by society and, in turn, influence the encoding and construction of memories in a culturally canonical fashion. The current research examined the self-goal of competence, which manifests through self-enhancement versus self-improvement motivations, in influencing remembering in different cultural contexts. We conducted two cross-cultural studies to examine memories for personal successes and failures (Study 1) and autobiographical and vicarious experiences (Study 2) in connection with individuals’ positive self-views. European Americans recalled a greater number of success than failure memories (Study 1) and US participants recalled a greater number of autobiographical than vicarious memories (Study 2), which was further associated with positive self-views at the individual level. In contrast, Asian (Study 1) and Chinese participants (Study 2) recalled even-handedly the different types of memories, and the memory retrieval was unrelated to individuals’ self-views. We discuss the findings in light of the different manifestations of the competence goal in shaping memory in the culturally modulated self-memory system.

The self-reference effect in attention deficit hyperactivity disorder.

The self-memory system depends on the prioritization and capture of self-relevant information, so may be disrupted by difficulties in attending to, encoding and retrieving self-relevant information. The current study compares memory for self-referenced and other-referenced items in children with ADHD and typically developing comparison groups matched for verbal and chronological age. Children aged 5-14 (N = 90) were presented with everyday objects alongside an own-face image (self-reference trials) or an unknown child's image (other-referenced trials). They were asked whether the child shown would like the object, before completing a surprise source memory test. In a second task, children performed, and watched another person perform, a series of actions before their memory for the actions was tested. A significant self-reference effect (SRE) was found in the typically developing children (i.e. both verbal and chronological age-matched comparison groups) for the first task, with significantly better memory for self-referenced than other-referenced objects. However, children with ADHD showed no SRE, suggesting a compromised ability to bind information with the cognitive self-concept. In the second task, all groups showed superior memory for actions carried out by the self, suggesting a preserved enactment effect in ADHD. Implications and applications for the self-memory system in ADHD are discussed.

Using shame to extend Martin Conway’s self-memory system

ABSTRACT We extend Conway’s self-memory system by adding theory and data from shame, an emotion that disrupts the internalised ideals of society needed for a positive self-concept. The event that caused 273 undergraduates their greatest amount of shame was analyzed; 66% were not very negative except for producing shame. Ratings of post-event effects, including two measure of self (self-perceived weakness, and centrality to identity) and four clinical symptoms (intrusions, avoidance, anxiety, and depression), were attributed separately to the remembered event, behaviour during the event, and shame from the event. The effects of shame were generally as large as the those of the event and larger than those of the behaviour, demonstrating the importance of shame’s effects. The Tonic Immobility Scale (TIS), which measures tonic immobility (i.e., freezing), was obtained for the event that produced the most tonic immobility but that was not the event that caused the most shame. The post-event symptoms measured on the event that caused the most shame and the TIS correlated highly, suggesting that shame and tonic immobility may belong to a cluster of phylogenetically conserved submissive defensive mechanisms that could account for effects currently attributed to goals in self-memory systems.

When “meaningless” means more: biographic resonance and audience appreciation of popular entertainment

Abstract Integrating predictions derived from the self-memory system and biographic resonance theory, the current project investigated the relationship between media-induced reminiscence and appreciation. In two experiments, undergraduates consumed popular entertainment from either their early adolescence or the present day. Study 1 (N = 406) featured music, and Study 2 (N = 405) featured movies. Both studies found that memory recall was more common in response to older (vs. recent) entertainment, and the memories activated by older entertainment were happier and produced more temporal comparisons. Although appreciation was higher for older entertainment in Study 1, this effect did not replicate in Study 2. However, both studies found that appreciation was higher for content that activated memories, especially memories that were more emotional and immersive. These patterns emerged regardless of when the content was released. These findings clarify why audiences sometimes perceive meaning in lighthearted entertainment, such as pop music or superhero films.

Самоопределяющие автобиографические воспоминания в системе личностно-мнемических межфункциональных связей

The aim of this paper is to extend the field of research in cultural-historical psychology by assimilating the construct of self-defining autobiographical memories (SDMs), which are in high demand among cognitive psychologists of personality. On the one hand, SDMs reflect one’s core motivation, personal traits, and leading goals. On the other hand, SDMs serve as a means of forming a sense of personal identity and continuity within one’s individual history. In the literature review, evidence supporting the SDM construct's validity was critically appraised through the lenses of individual differences, correlations with other variables, clinical cases, and experimental results on causal links between SDM transformation and various measures of personality. The Self-Memory System model (SMS), which connects autobiographical memory and the self, is discussed as a pertinent framework for interpreting SDM’s unique properties. The argument ends with the proposition that the cultural-historical approach would benefit from accommodating SDMs as an ideal mediator of interfunctional relationships, both inside personality and between personality and cognitive processes.

Predicting the trend of infectious diseases using grey self-memory system model: a case study of the incidence of tuberculosis

ObjectivesThe prediction and early warning of infectious diseases is an important work in the field of public health. This study constructed the grey self-memory system model to predict the incidence trend of infectious diseases affected by many uncertain factors. Study designThe design of this study is a combination of the prediction method and empirical analysis. MethodsBy organically coupling the self-memory algorithm with the mean GM(1,1) model, the tuberculosis incidence statistics of China from 2004 to 2018 were selected for prediction analysis. Meanwhile, by comparing with the other traditional prediction methods, three representative accuracy check indexes (MSE, AME, MAPE) were conducting for error analysis. ResultsOwing to the multiple time-points initial fields, which replace the single time-points, the limitation of the traditional grey prediction model, which is sensitive to the initial value, is overcome in the self–memory equation. Consequently, compared with the mean GM model and other statistical methods, the grey self-memory model shows significant forecasting advantages, and its single-step rolling prediction accuracy is superior to other prediction methods. Therefore, the incidence of tuberculosis in China in the next year can be predicted as 55.30 (unit: 1/105). ConclusionsThe grey self-memory system model can closely capture the individual random fluctuation in the whole evolution trend of the uncertain system. It is appropriate for predicting the future incidence trend of infectious diseases and is worth popularizing to other similar public health prediction problems.

The Me in Memory: The Role of the Self in Autobiographical Memory Development.

This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N=186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood.

Exploring self through memory: Narratives of Punjabi and Sindhi Partition survivors

The reciprocal association between working self and autobiographical retrieval is illustrated in the self-memory system model. This study attempted to investigate the self-memory system model in the context of memories of the 1947 Partition of British India. This event, which dramatically altered the lives of many survivors, generated indelible memories. In this study, the published Partition narratives of displaced Punjabi and Sindhi survivors were content analyzed, and themes were extracted. The working self of the Partition survivors triggered recall of this event, whose evaluation varied along three dimensions, namely, avoidance, rumination, and reflection. The theme of repression was central to avoidance narratives. Furthermore, rumination narratives were marked by nostalgia and a sense of alienation. Finally, the themes of cognitive reappraisal, self-complexity, and self-discrepancy resolution surfaced in reflection narratives. The emerging research findings highlight the centrality of emotion regulation in autobiographical retrieval and its implications for well-being.

The Importance of Memory Specificity and Memory Coherence for the Self: Linking Two Characteristics of Autobiographical Memory.

Autobiographical memory forms a network of memories about personal experiences that defines and supports well-being and effective functioning of the self in various ways. During the last three decades, there have been two characteristics of autobiographical memory that have received special interest regarding their role in psychological well-being and psychopathology, namely memory specificity and memory coherence. Memory specificity refers to the extent to which retrieved autobiographical memories are specific (i.e., memories about a particular experience that happened on a particular day). Difficulty retrieving specific memories interferes with effective functioning of the self and is related to depression and post-traumatic stress disorder. Memory coherence refers to the narrative expression of the overall structure of autobiographical memories. It has likewise been related to psychological well-being and the occurrence of psychopathology. Research on memory specificity and memory coherence has developed as two largely independent research domains, even though they show much overlap. This raises some important theoretical questions. How do these two characteristics of autobiographical memory relate to each other, both theoretically and empirically? Additionally, how can the integration of these two facilitate our understanding of the importance of autobiographical memory for the self? In this article, we give a critical overview of memory specificity and memory coherence and their relation to the self. We link both features of autobiographical memory by describing some important similarities and by formulating hypotheses about how they might relate to each other. By situating both memory specificity and memory coherence within Conway and Pleydell-Pearce’s Self-Memory System, we make a first attempt at a theoretical integration. Finally, we suggest some new and exciting research possibilities and explain how both research fields could benefit from integration in future research.

Switch costs in the self-memory system.

Two experiments on undergraduates examined the idea that the working self operates as an executive structure to constrain and co-ordinate the generation of autobiographical memories. A switching task was used, in which participants completed an autobiographical memory fluency task, using either alternating self-image cues or the same cue repeatedly. In two experiments, there was a clear switch cost, whereby participants took longer to generate autobiographical memories when alternating between two different self-images. In the second experiment, there was also a similar cost associated with generating names and places from two separate domains, home and university. Taken together, these experiments support the idea that autobiographical memories and personal semantics are organized into a hierarchical structure, which can be probed using executive-function-like tasks. In particular, the task switch cost points to retrieval systems being geared up to retrieving memories according to the current goals of the self. In terms of autobiographical retrieval, the self can thus be thought of as a mental structure that is subject to dynamic patterns of excitation and interference.

Les troubles de la mémoire autobiographique et du self dans la schizophrénie

ObjectivesDisorders of self in schizophrenia have been considered as the core feature of the illness since its early clinical description. However, until recently, the understanding of these disorders referred mostly to philosophical considerations. The aim of this work is to examine how the various aspects of autobiographical memory deficits may be considered as possible cognitive mechanisms accounting for self-disorders in patients. MethodsWe performed a theoretical review of the literature on autobiographical memory studies in schizophrenia. Our approach of cognitive psychopathology was grounded in the model of the Self-Memory System put forward by Conway (2005), which posits reciprocal relationships between autobiographical memory and the self. This model stresses the distinction between the working-self and the autobiographical memory knowledge base. The latter contains all autobiographical information stored in our life and is organized according to the specificity of this information. The role of the working-self is to maintain the coherence of the self and to control the access to autobiographical memories and corresponding memory details. The working-self supports an experiential or phenomenological dimension of the self, especially when a highly detailed autobiographical memory is retrieved, and a past event is re-experienced by the rememberer. The working-self also entails a conceptual part, the conceptual self, which contains self-knowledge and self-images. ResultsOur review showed that autobiographical memories of patients with schizophrenia are less specific and contain fewer phenomenological details than those of healthy participants. Patients also have difficulty assessing the subjective temporal distance of past events, and their ability to re-experience unique past personal events is affected as shown by a reduced conscious recollection and a smaller frequency of Field visual perspective during recall of autobiographical memories. This global alteration of all phenomenological characteristics of autobiographical memories strongly suggests an alteration of the phenomenological dimension of the self in schizophrenia. Since some of these alterations are also found in patients when they plan for future personal events, the ability to mentally travel in time is reduced in patients and reflects an impaired sense of self across time. The literature also shows that self-images are more passive, less coherent and less stable in time in patients compared to healthy participants. These results point to an alteration of the conceptual dimension of the self in schizophrenia. This may be partly explained by a weaker connection between the self and autobiographical memory and by other alterations of autobiographical memories closely linked to the self. In fact, the reminiscence bump is disorganized in patients and comprises poorly detailed memories. Memories grounding self-images are less organized and weakly connected to self-images. Finally, patients have an impaired ability to give a meaning to or to draw lessons from self-defining memories of their life. ConclusionBased on these results, we discuss current and future therapeutic interventions including both cognitive remediation methods and cognitive psychotherapy applied to autobiographical memory. These methods appear relevant to help patients improve both the sense of self associatied with their autobiographical memory retrieval and the coherence and stability of the self.

Autobiographical Memory in the Angry Self.

The impact of anger on autobiographical recall was examined in two studies. In Experiment 1, 76 participants differing in trait anger completed an autobiographical memory task (AMT). In Experiment 2, 50 participants with elevated trait anger were either provoked or not provoked and subsequently completed an AMT. Across both studies, participants with high dispositional anger reported more anger-related memories, describing themselves as the primary agent of anger. In Experiment 2, provoked participants reported more memories describing themselves as the target of anger. These findings highlight the distinct patterns of memory recall associated with trait versus state anger. Findings are discussed in terms of retrieval biases operating in angry individuals and proposals stemming from self-memory system models of autobiographical memory.

Disruption of temporally extended self-memory system following traumatic brain injury

We investigated for the first time the episodic/semantic distinction in remembering the past and imagining the future in traumatic brain injury (TBI), and explored cognitive mechanisms that may underlie their deficits. Fifteen severe TBI patients and 15 control participants performed a battery of neuropsychological tests and a set of verbal fluency tasks designed to assess semantic (personality traits knowledge and general events), and episodic (specific events and details) facets of self-representations according to three time periods (remote/retrograde past, recent/anterograde past, future). Compared to controls, TBI patients showed deficits in both semantic and episodic self-representations, regardless of the time period, and controlling for basic cognitive functions. By contrast, a subjective evaluation of self-concept measuring the degree of certitude and the valence of self did not differ between patients and controls. The deficits were mainly predicted by altered executive function (i.e., updating) for past periods, as well as by general semantic and feature binding in working memory for the future period, independently of the injury characteristics. For controls, only episodic self-representation for each time period was mediated by executive or working memory functions, while semantic self-representation was mediated by the certitude of the self. This study highlights the dual role of semantic and episodic representations in temporally extended self, and shows the global disruption of self-representations across extended time in severe TBI. This encourages the extension of past and future thinking research to TBI populations to provide important insights into the nature and origin of these deficits and their role in recovery and to suggest future lines of research on rehabilitation procedures.

Remembering, imagining, false memories & personal meanings.

The Self-Memory System encompasses the working self, autobiographical memory and episodic memory. Specific autobiographical memories are patterns of activation over knowledge structures in autobiographical and episodic memory brought about by the activating effect of cues. The working self can elaborate cues based on the knowledge they initially activate and so control the construction of memories of the past and the future. It is proposed that such construction takes place in the remembering-imagining system - a window of highly accessible recent memories and simulations of near future events. How this malfunctions in various disorders is considered as are the implication of what we term the modern view of human memory for notions of memory accuracy. We show how all memories are to some degree false and that the main role of memories lies in generating personal meanings.

Measuring Autobiographical Fluency in the Self-Memory System

Autobiographical memory is widely considered to be fundamentally related to concepts of self and identity. However, few studies have sought to test models of self and memory directly using experimental designs. Using a novel autobiographical fluency paradigm, the present study investigated memory accessibility for different levels of self-related knowledge. Forty participants generated 20 "I am" statements about themselves, from which the 1st, 5th, 10th, 15th, and 20th were used as cues in a two-minute autobiographical fluency task. The most salient aspects of the self, measured by both serial position and ratings of personal significance, were associated with more accessible sets of autobiographical memories. This finding supports theories that view the self as a powerful organizational structure in memory. Results are discussed with reference to models of self and memory.

What Happens Next?: How Ovarian Cancer Forces a Woman into a New Draft of Her Life Script

A diagnosis of ovarian cancer has an impact on many areas of a woman's life which define her identity and life story. Women are forced to reconsider the future ‘scenes’ of their life scripts as they deal with the loss of fertility, a challenge to plans and existential threat. This paper considers this experience within the theoretical framework of the Self-Memory System. Alongside this theory, the author shares her use of dramatherapy tools applied to weekend residential courses run across the UK on four occasions to support women affected by ovarian cancer.

Shifting Self, Shifting Memory: Testing the Self-Memory System Model With Hypnotic Identity Delusions

According to Conway's self-memory system (SMS) model, autobiographical memories may be facilitated, inhibited, or misremembered to be consistent with current self. In 3 experiments, the authors tested this by hypnotically suggesting an identity delusion and indexing whether this shift in self produced a corresponding shift in autobiographical memory. High hypnotizable participants displayed a compelling identity delusion and elicited specific autobiographical events that they could justify when challenged. These memories were reinterpretations of previous experiences that supported the suggested identity. Importantly, autobiographical memories that were no longer consistent with the hypnotically deluded self were less accessible than other memories. The authors discuss these findings in the context of Conway's SMS model and propose 2 accounts of autobiographical remembering during hypnotic and clinical delusions.

Development in the Organization of Episodic Memories in Middle Childhood and Adolescence

The basic elements of autobiographical or episodic memory are established in early childhood, although the exact age at which memories gain episodic status is still under contention. The self-memory system proposed that adults use “lifetime periods” to group episodic memories together into chapters of the life story – an evolving and internalized account of significant life events that are self-defining. Two studies examined at what point in development children or adolescents begin to take advantage of lifetime-period chapters to organize their episodic memories. The results of Study 1 with 8- to 12-year-olds revealed that the ability to provide life story chapters began to emerge as early as 8 years of age. In Study 2 with adolescents aged 12–21, this ability continued to develop into late adolescence among New Zealand European (NZE) and New Zealand Chinese (NZC) adolescents; however, cultural differences also existed in the specificity of memories. NZC adolescents narrated fewer life story chapters containing specific memories than NZE adolescents. These findings support and extend current theories of episodic memory by specifying that pre-adolescents are starting to organize their episodic memories into lifetime periods, but this achievement is not fully realized until later in adolescence.

Functional independence within the self-memory system: New insights from two cases of developmental amnesia

Neuropsychological and neuroimaging data suggest that the self-memory system can be fractionated into three functionally independent systems processing personal information at several levels of abstraction, including episodic memories of one's life (episodic autobiographical memory, EAM), semantic knowledge of facts about one’s life (semantic autobiographical memory, SAM), and semantic knowledge of one's personality [conceptual self, (CS)]. Through the study of two developmental amnesic patients suffering of neonatal brain injuries, we explored how the different facets of the self-memory system develop when growing up with bilateral hippocampal atrophy. Neuropsychological evaluations showed that both of them suffered from dramatic episodic learning disability with no sense of recollection (Remember/Know procedure), whereas their semantic abilities differed, being completely preserved (Valentine) or not (Jocelyn). Magnetic resonance imaging, including quantitative volumetric measurements of the hippocampus and adjacent (entorhinal, perirhinal, and temporopolar) cortex, showed severe bilateral atrophy of the hippocampus in both patients, with additional atrophy of adjacent cortex in Jocelyn. Exploration of EAM and SAM according to lifetime periods covering the entire lifespan (TEMPAu task, Piolino et al., 2009) showed that both patients had marked impairments in EAM, as they lacked specificity, details and sense of recollection, whereas SAM was completely normal in Valentine, but impaired in Jocelyn. Finally, measures of patients' CS (Tennessee Self-Concept Scale, Fitts and Warren, 1996), checked by their mothers, were generally within normal range, but both patients showed a more positive self-concept than healthy controls. These two new cases support a modular account of the medial-temporal lobe with episodic memory and recollection depending on the hippocampus, and semantic memory and familiarity on adjacent cortices. Furthermore, they highlight developmental episodic and semantic functional independence within the self-memory system suggesting that SAM and CS may be acquired without episodic memories.
