Autobiographical memory specificity and emotional disorder   总被引:7,自引:0,他引:7  
The authors review research showing that when recalling autobiographical events, many emotionally disturbed patients summarize categories of events rather than retrieving a single episode. The mechanisms underlying such overgeneral memory are examined, with a focus on M. A. Conway and C. W. Pleydell-Pearce's (2000) hierarchical search model of personal event retrieval. An elaboration of this model is proposed to account for overgeneral memory, focusing on how memory search can be affected by (a) capture and rumination processes, when mnemonic information used in retrieval activates ruminative thinking; (b) functional avoidance, when episodic material threatens to cause affective disturbance; and (c) impairment in executive capacity and control that limits an individual's ability to remain focused on retrieval in the face of distraction.  相似文献

To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without a current diagnosis of posttraumatic stress disorder (PTSD). Each rated their three most-stressful, three most-positive, seven most-important and 15 word-cued autobiographical memories, and completed tests of personality and mood. Involuntary memories were then recorded and rated as they occurred for 2 weeks. Standard mechanisms of cognition and affect applied to extreme events accounted for the properties of stressful memories. Involuntary memories had greater emotional intensity than voluntary memories, but were not more frequently related to traumatic events. The emotional intensity, rehearsal, and centrality to the life story of both voluntary and involuntary memories, rather than incoherence of voluntary traumatic memories and enhanced availability of involuntary traumatic memories, were the properties of autobiographical memories associated with PTSD.  相似文献

Memory and awareness in a patient with multiple personality disorder   总被引:1,自引:0,他引:1  
We studied an individual with multiple personality disorder in whom each of several personalities claimed to have no direct awareness of the others and to be unable to consciously remember the experiences of other personalities. A broad selection of implicit and explicit memory tests was used to determine the extent to which one personality had access to knowledge acquired by another and the circumstances in which that knowledge would be expressed. The implicit assessment of memory was a necessary but not sufficient condition for demonstrating interpersonality access. The degree of compartmentalization of knowledge in this patient depended largely on whether the interpretation of presented information was likely to differ across personalities.  相似文献

The dissociative disorder known as multiple personality disorder (MPD) presents a diagnostic challenge to psychological assessment techniques. A case example is presented in which a new self-report, multifactorial measure of ego functioning discriminated distinct profiles for four personalities within one multiple personality organization. Interpretations of characteristics of the primary and secondary personalities based on the Bell Object Relations Reality Testing Inventory (BORRTI) are presented. The relationship between these findings and other approaches to psychological testing for dissociation and MPD are discussed. It is suggested that this approach will facilitate the clinical assessment of suspected MPD subjects and contribute to affording appropriate treatment to this population.  相似文献

Two studies tested whether autobiographical memory content and phenomenology mediate two consistent findings in the personality literature: Neuroticism and subjective health and Conscientiousness and achievement striving. In Study 1, participants (N = 162) retrieved and rated four memories and completed measures of Neuroticism and subjective health. In Study 2, participants (N = 345) retrieved and rated two memories and completed measures of Conscientiousness and achievement goals and study strategies. In both studies, memory content and phenomenology mediated the relations between personality and health and achievement in expected ways. For example, participants high in Neuroticism reported more somatic complaints because their memories were saturated with negative affective content. Discussion focuses on the utility of integrating trait and social–cognitive approaches to personality.  相似文献

Experts advise against referring persons with multiple personality disorder to diagnostically heterogeneous groups. As more multiples are admitted to inpatient units this presents a problem. Excluding persons of a particular diagnosis from groups makes it difficult to promote a cohesive therapeutic milieu. I have found that multiples can be managed successfully in mixed groups. The leader is advised to adhere to a reliable structure and pay close attention to boundary issues. Themes for discussion must be judiciously evaluated so that effectiveness is not undermined. Patients with different diagnoses can come to appreciate their similarities and benefit from groups.  相似文献

Autobiographical memory was examined in participants with seasonal affective disorder (SAD). In Experiment 1, participants with SAD performed an autobiographical memory task (AMT) in the winter, when depressed. The AMT required participants to generate autobiographical memories to positive and negative cue words. Symptom levels were reassessed in the summer, when participants were remitted. The number of overly general memories to positive cues generated when the SAD participants were depressed predicted symptom levels when remitted, over and above initial symptom levels, with greater winter overgenerality being associated with high levels of summer symptoms. However, this was dependent on the exact measure of depressive symptoms used. The degree of overgenerality of memories in SAD participants was further investigated in Experiment 2. Results revealed that SAD participants did not show elevated recall of overgeneral memories relative to controls. The results as a whole indicate that, even when levels of general memories are no greater in a given target group than in controls, the absolute level of general memories to positive cue words is still independently related to symptom outcome.  相似文献

In this paper I compare the phenomenology of near-death experiences to that of multiple personality disorder. The comparison reveals a number of similarities, including out-of-body experiences, the transcendental environment, encounter with the higher self, possible temporal lobe involvement, and antecedent child abuse. Rather than being disparate and unrelated experiences, I suggest that the near-death experience and multiple personality disorder may be variants of the same basic phenomenological pattern.  相似文献

Abstract

Previous experiments on the recall of threatening and neutral information in clinically anxious subjects have yielded mixed results. The present study assessed autobiographical memory in patients with generalised anxiety disorder (GAD), and normal controls. Subjects were first presented with neutral cue words and asked to respond with any personal memory. GAD subjects judged the content of their own memories as more consistent with anxious mood, and less consistent with pleasant mood, than that reported by controls. Subjects were then again presented with neutral cue words, but with instructions to provide either “anxious” or “nonanxious” personal memories, on specified trials. Significant interactions between group and instruction condition indicated that anxious subjects recalled more anxiety-evoking memories, and recalled them more rapidly, relative to controls. Ratings by blind judges did not support the hypothesis that this apparent difference in the content of autobiographical recall was an artefact due to anxious subjects labelling memories as being more anxiety evoking than would controls. Possible explanations of the findings, and reasons for the apparent discrepancy between these and earlier results, are discussed.  相似文献

Recent studies have found that angry individuals are characterized by more pronounced attentional and interpretation biases toward threat than anxious individuals. The present study examined anger-related, anxiety-related, and neutral autobiographical memories in 35 angry participants, 33 anxious participants, and 29 non-angry/non-anxious, or healthy participants. Objective indices of autobiographical memories (i.e., retrieval latency, coding of specificity and affective tone) suggested that groups retrieved memories with similar properties. However, both angry and anxious participants rated their memories as less pleasant than healthy participants. These results indicate that memory biases are not part of the cognitive sequelae associated with anger and anxiety, although aspects of the appraisal of these personal memories are distorted.  相似文献

Premorbid personality characteristics could have a pathoplastic effect on behavioral symptoms and personality changes related to neurodegenerative diseases. Patients with personality disorders, in particular of the dramatic cluster, may present functional frontolimbic abnormalities. May these neurobiological vulnerabilities linked to a premorbid personality disorder predispose or represent a risk factor to subsequently develop a neurodegenerative disorder? Are subjects with personality disorders more at risk to develop a dementia than mentally healthy subjects? This topic is discussed presenting the clinical case of a patient who suffered of a probable Narcissistic Personality Disorder and subsequently developed a clinically diagnosed Frontotemporal Dementia.  相似文献

In amnestics with anterograde amnesia, memories of post-onset autobiographical experiences, if present at all, are typically barren and impoverished. However, there have been sporadic reports of islands of memory--memories that are vivid, detailed, and specific to time and place. The aim of this study was to verify the presence of such memories and examine their incidence rate. Anterograde amnestics were interviewed in their home using a narrative interviewing strategy with a view to describing memory in everyday life. Each autobiographical memory of a post-onset event was coded for quantity-length, and quality-episodicity. In just over half of the amnestics (8 out of 14), a memory that was lengthy, rich in personal details, and localisable was recollected. The quantitative and qualitative aspects of these island memories were significantly different from the other autobiographical memories that the amnestics supplied. These memories were at odds with what would be expected on the basis of their performance on standardised memory instruments. Our findings suggest there is occasionally more variability in remembering of autobiographical experiences in some amnestics than has traditionally been believed.  相似文献

This article reports on a study of autobiographical memory in two older adults, wife and husband, over a retention interval of 20 years. The female participant kept a 20-year log of daily events. A sampling of events that varied in distinctiveness, from unique, one-of-a-kind events to routine, almost daily events, was used to examine cued recall using an incremental scoring system. Each event recalled was also rated on phenomenological scales of remembering versus knowing, rehearsal, and importance. The strongest effect on recall was the order of the cues, with an initial what cue, containing the content of the event, proving superior to cues containing who or where elements. When was the most effective second cue. The results demonstrate regularity in retention over time and highlighted the utility of this approach for understanding the factors that influence autobiographical memory performance.  相似文献

The authors investigated autobiographical memory specificity in subjects who formerly had depression. In 122 euthymic patients with at least two previous major depressive episodes, memory specificity was significantly impaired compared to matched control participants but not related to residual symptoms and illness characteristics, was not differentially affected by cognitive therapy, and was also not predictive of relapse/recurrence during the 2-year follow-up. However, memory specificity was associated with age, education, and immediate and delayed memory recall. The results suggest that memory specificity may reflect a global cognitive impairment that remains in patients who (formerly) had depression but does not constitute a trait marker for vulnerability for relapse/recurrence.  相似文献

This special issue of Memory spotlights research that uses a functional approach to investigate autobiographical memory (AM) in everyday life. This approach relies on studying cognition, in this case AM, taking into account the psychological, social, or cultural-historic context in which it occurs. Areas of interest include understanding to what ends AM is used by individuals and in social relationships, how it is related to other cognitive abilities and emotional states, and how memory represents our inner and outer world. One insight gained by taking this approach is that levels and types of accuracy need not always be regarded as memory "failures" but are sometimes integral to a self-memory system that serves a variety of meaningful ends of human activity. Previously hypothesised functions of AM fall into three broad domains: self, social, and directive. Each of the contributions addresses how AM serves one or more of these functions and thereby examines the usefulness and adequacy of this trio.  相似文献
