Relationship between frequency of involuntary autobiographical memories and cognitive failure

Involuntary autobiographical memories are memories of personal experiences that pop into mind without a conscious attempt at their retrieval. This study investigated individual differences in the number of involuntary autobiographical memories, and explored the relationship between the frequency of occurrence in involuntary autobiographical memory and cognitive failures in everyday memory, as indexed by metamemory questionnaires. A total of 24 undergraduate students reported involuntary autobiographical memories in controlled field interviews, and completed the Everyday Memory Questionnaire and the Cognitive Failures Questionnaire. The results showed that, despite controlled conditions, considerable individual differences were observed in the number of involuntary autobiographical memories reported while walking along a prescribed route on the campus, and that reported memories were predominantly serving self function. In addition, the number of involuntary autobiographical memories was positively related to cognitive failures in everyday memory: participants who acknowledged more problems in everyday memory had a higher frequency of involuntary memories. The implications of these results are discussed in terms of the complementary function of involuntary autobiographical memory in everyday life.     

A comparison of involuntary autobiographical memory retrievals

This study compared three different ways autobiographical memories are elicited involuntarily: (1) cued by an active goal common to memory and retrieval contexts in combination with sensory information associated with this goal‐directed activity; (2) cued by sensory information that does not relate to goal‐directed activity common to both memory and retrieval contexts; and (3) activated when no identifiable cue present in retrieval context. Two hundred and twenty eight participants recorded details of a single autobiographical memory that resulted naturally from a spontaneous, non‐deliberate retrieval. Nearly all recorded memories described specific events (83%) with very few memories less than 7 days old (8%) and many memories more than 5 years old (44%). No significant differences resulted between the three retrieval types for the age, specificity or prior rehearsal of memories reported. However, the level of attention at retrieval was significantly more diffuse for retrievals without a clearly identifiable cue. The authors discuss the implications of these findings for current models of involuntary autobiographical memory retrieval. Copyright © 2006 John Wiley & Sons, Ltd.     

The neural basis of autobiographical and semantic memory: new evidence from three PET studies

A novel, neuropsychologically informed paradigm (extended retrieval of events in response to a cue word) was used to investigate the neural basis of autobiographical and semantic memory. Contrasting retrieval of autobiographical memories with retrieval of semantic facts (ABM-SEM) in 24 subjects across three PET studies revealed bilateral involvement of the middle temporal gyrus (BA 21) and medial frontal cortex (BA 9/10). The opposite contrast, SEM-ABM, resulted in increased regional cerebral blood flow in left posterior temporal regions (BA 37) and left prefrontal cortex (BA 45/46). Laterality maps suggest that the bilateral pattern seen in our studies, but not often in other neuroimaging investigations, reflects the use of a task stressing retrieval of specific personal events. Further comparisons revealed that the activation in the right anterior temporal lobe during autobiographical recall was virtually identical to that seen during retrieval of information about famous people or events in contrast with retrieval of general semantic facts. These findings suggest that the retrieval of an autobiographical event requires participation from conceptual knowledge, and that this type of knowledge is bilaterally distributed in the temporal lobes.     

自传记忆提取的神经机制及其研究方法

自传记忆（autobiographical memory,AM）是个人生活事件的记忆,它在人类认知中建构起自我、情绪、个人意义及其交互作用的主通道。对自传记忆的研究在广度上极大丰富了记忆的研究内容,并成为记忆研究乃至整个认知心理学新的方法论的增长点。利用PET,fMRI和皮层慢电位等手段对自传记忆进行研究,可以加深对自传记忆神经机制的认识。就Conway等提出的SMS模型中,自传记忆提取的神经解剖分布,自传记忆提取偏侧化问题和海马在自传记忆中的作用进行总结和评述,并分析比较了自传记忆脑机制的研究方法     

Autobiographical memory deficits in schizophrenia

This study investigated autobiographical memory processes in a group of individuals diagnosed with schizophrenia and matched controls. The schizophrenia group displayed an overgeneral style of autobiographical memory retrieval on two widely used measures, and displayed problems retrieving both autobiographical facts and events. They showed a specific impairment in the recall of autobiographical events and facts in early adulthood, around the time of onset of their illness. Retrieval deficits were independent of mood state and premorbid intellectual functioning. The magnitude of the deficits in autobiographical memory retrieval specificity were considerably greater than any general impairments in episodic and working memory.     

不随意自传体记忆研究述评

不随意自传体记忆指,个人过去经历的事件在没有主动提取的情况下自动浮现于脑海的记忆现象。文章从不随意自传体记忆的研究方法、记忆特点和理论解释三个方面,分别介绍结构日记、词汇联想、栅栏任务和压力电影范式等研究方法;说明了不随意自传体记忆提取直接性、内容具体性和情绪影响性等特性,认为其原因是记忆内容的非整合性和显著联结;阐述了全局工作空间智能分布模型、双重表征理论和认知模型理论及其解释能力理论与不足。最后指出未来研究应关注特殊性质的解释、记忆结构整合和记忆的功能探究。     

自传体记忆的情绪对其相关信息内隐提取的影响

本研究主要考察自传体记忆本身的情绪是否影响该记忆相关信息的内隐提取过程。取大学生15人完成实验, 实验分为两部分：记忆提取和词汇判断。首先在记忆提取阶段, 要求被试根据词对(形容词-中性名词)提取积极、消极和中性情绪色彩的自传体记忆事件。接着在词汇判断任务中, 要求被试对包含提取过记忆的中性名词的词语进行词和非词的判断, 并且记录相应的脑电波。结果发现：(1)被试按要求成功提取了积极、消极和中性三类自传体记忆事件。词汇判断任务中, 内隐提取三类自传体记忆信息的反应时和正确率均无显著差异。(2)相比于积极、中性自传体记忆信息, 消极自传体记忆信息提取的过程中的ERP波幅更大, 更偏向于正向。这表明自传体记忆信息的内隐提取受到记忆本身情绪的影响, 消极自传体记忆信息提取需要付出更多资源。     

Rumination and overgeneral autobiographical memory

Two studies investigated the effects of rumination on the retrieval of autobiographical memories in high-depressed and low-depressed individuals. Experiment 1 administered either a rumination or distraction task prior to a cued autobiographical memory task. High-depressed participants recalled more overgeneral memories following rumination relative to distraction, whereas experimental inductions did not influence low-depressed participants. Experiment 2 administered either a positive or negative rumination task prior to a cued autobiographical memory task. Negatively valenced rumination led high-depressed participants to recall more overgeneral memories than positively valenced rumination; this effect was not observed in low-depressed participants. These findings accord with the proposal that rumination is a mediating mechanism in the retrieval of overgeneral memories, and extends this proposal by indicating that negatively valenced ruminative content is particularly instrumental in inducing overgeneral retrieval.     

Placing events in time: the role of autobiographical recollection

Episodic experience is argued to be rich in temporal information, but it remains unclear whether temporal information is directly coded in the event memory or is reconstructed at retrieval. The two experiments reported here emphasise the role of reconstructive processes of autobiographical context in establishing the date of memories. Younger and older participants were presented with famous public events, although only the latter had actually lived through them. Participants were asked to make forced-choice judgements about the date of the event and other event-related facts. Overall, while the older group showed better fact knowledge of the events, this did not translate into better dating performance. This older group showed similar dating performance across events with high and low factual knowledge. In contrast, the younger group's dating accuracy was determined by their level of knowledge. This suggests that older individuals who have direct episodic experience of an event may perform the task in a qualitatively different manner, eschewing semantic facts in favour of other sources of information. Crucially, this process does not appear to enhance performance. A second experiment addressed the issue of whether older participants date events based on general qualities of the event memory (e.g., vividness), the availability of other event-related semantic facts, or autobiographical context. It was found that the ability to place an event in autobiographical context is related to dating accuracy, but not to other aspects of memory.

Judgement of confidence in childhood memories

Memory judgement processes, based on the characteristics and associations of retrieved memories such as sensory details and supporting memories, are considered as important as retrieval in several autobiographical memory models. Judgement processes have received less research attention than memory characteristics themselves. The present studies examined memory judgement using qualitative analysis of the reasons participants gave for confidence in retrieved childhood memories. For memories they were confident of, participants cited memory phenomenology, especially sensory and affective details, much more frequently than consistency with other autobiographical knowledge. For memories they were not confident of, participants reported lack of consistency with autobiographical knowledge or with others' memories more often than memory phenomenology as reasons for their uncertainty. Participants' comments also revealed several metacognitive beliefs about the relationship between memory characteristics and accuracy. These data are consistent with two‐process models of memory judgement associated with true versus false memories. Copyright © 2007 John Wiley & Sons, Ltd.

Searching for two things at once: Evidence of exclusivity in semantic and autobiographical memory retrieval

We examined whether retrieval from semantic memory (Experiment 1) and autobiographical memory (Experiment 2) is exclusive, or whether people can search for two things at once. In Experiment 1, participants retrieved items as quickly as possible over 4 ruin from single categories (e.g., foods, countries) and from disjunctive categories (e.g., foods or countries). In Experiment 2, participants retrieved autobiographical episodes associated with single cue words (e.g., flower, ticket) or with disjunctive cue words (e.g., flower or ticket). In both experiments, retrieval of items from the disjunctive category did not exceed predictions based on optimal sequencing of retrieval from the corresponding two single categories. That is, exclusivity was observed to occur in retrieval from among multiple nonoverlapping categories in both semantic and autobiographical memory.     

Autobiographical elaboration reduces memory distortion: cognitive operations and the distinctiveness heuristic

Retrieval monitoring enhances episodic memory accuracy. For instance, false recognition is reduced when participants base their decisions on more distinctive recollections, a retrieval monitoring process called the distinctiveness heuristic. The experiments reported here tested the hypothesis that autobiographical elaboration during study (i.e., generating autobiographical memories in response to cue words) would lead to more distinctive recollections than other item-specific encoding tasks, enhancing retrieval monitoring accuracy at test. Consistent with this hypothesis, false recognition was less likely when participants had to search their memory for previous autobiographical elaborations, compared to previous semantic judgments. These false recognition effects were dissociated from true recognition effects across four experiments, implicating a recollection-based monitoring process that was independent from familiarity-based processes. Separately obtained subjective measures provided converging evidence for this conclusion. The cognitive operations engaged during autobiographical elaboration can lead to distinctive recollections, making them less prone to memory distortion than other types of deep or semantic encoding.     

Autobiographical Memory, Self, and Stress-Related Psychiatric Disorders: Which Implications in Cancer Patients?

Autobiographical memory refers to information and memories of personal life events, accumulated since childhood, which enable the construction of a feeling of identity and continuity. Autobiographical memory retrieval is a dynamic and reconstructive process, as mental representations change with the passage of time. This flexible aspect of memory is linked to one’s changing self and aspirations over time, that evolve according to our personal status and environment. Hence, any breakdown in the continuity of life involves a distortion of memory. Such distortions can be observed in stress-related psychiatric disorders, such as major depression or post-traumatic stress disorder, where autobiographical memory retrieval is characterized by overgenerality (i.e., the tendency to recall generic memories rather than specific events in response to cue words). Such memory disorders can be observed at different degrees in cancer patients. We will report studies focusing on the above-mentioned psychiatric disorders and cancer, and will attempt to establish a relation with autobiographical memory disturbances. The better understanding of such memory deficits could permit new pathophysiological hypotheses to emerge. Recommendations for future research that will enhance understanding of the factors that contribute to autobiographical memory in cancer are suggested.     

Inner speech and bilingual autobiographical memory: a Polish-Danish cross-cultural study.

Thirty years after fleeing from Poland to Denmark, 20 immigrants were enlisted in a study of bilingual autobiographical memory. Ten "early immigrators" averaged 24 years old at the time of immigration, and ten "late immigrators" averaged 34 years old at immigration. Although all 20 had spent 30 years in Denmark, early immigrators reported more current inner speech behaviours in Danish, whereas late immigrators showed more use of Polish. Both groups displayed proportionally more numerous autobiographical retrievals that were reported as coming to them internally in Polish (vs Danish) for the decades prior to immigration and more in Danish (vs Polish) after immigration. We propose a culture- and language-specific shaping of semantic and conceptual stores that underpins autobiographical and world knowledge.     

依恋视角下自传体记忆提取的差异

自传体记忆是关于个人生活的记忆, 依恋理论为自传体记忆的理解提供重要的理论框架。本文以个体依恋风格的差异为视角, 根据Conway和Pleydell-Pearce’s的自我记忆系统(Self-Memory System)总结出在自传体记忆提取的过程中, 依恋系统具有目标导向、防御排斥和情绪调节的作用。安全型相较于非安全型依恋的个体在自传体记忆提取的数量、具体性、准确性、通达性和情绪强度、情绪唤醒度上具有优势。未来研究可以从依恋系统的激活, 焦虑型、回避型依恋在记忆提取中具体成分的差异, 依恋与不随意自传体记忆提取的关系上来探讨。     

Activating attachment representations impact how we retrieve autobiographical memories

Although much research indicates that proximity to attachment figures confers many psychological benefits, there is little evidence pertaining to how attachment activation may impact autobiographical memory retrieval. Following a negative mood induction to elicit overgeneral autobiographical retrieval, participants (N?=?70) were administered an induction in which they imagined a person who is a strong attachment figure or an acquaintance. Participants then completed an autobiographical memory task to retrieve memories in response to neutral and negative cue words. Attachment priming resulted in less distress, increased retrieval of specific memories, and reduced retrieval of categoric memories. These findings indicate that activation of mental representations of attachment figures can impact on the specificity of autobiographical memory retrieval, and extends prevailing models of autobiographical memory by integrating them with attachment theory.
