Our aim was to investigate the functional underpinnings of autobiographical memory (AM) impairment in multiple sclerosis (MS) patients. To that end, 18 patients and 18 controls underwent the autobiographical interview (AI). Subsequently, the 36 participants underwent a functional magnetic resonance imaging (fMRI) session designed to assess the construction and elaboration of AMs. A categorical control task was also presented. Patients were trained in the fMRI procedure to optimise the procedural aspects accompanying the task itself. Although the patients obtained significantly poorer AI scores (p < .001), their performance on the easier AM fMRI task was efficiently carried out, allowing relevant comparisons with healthy controls. Relatively to healthy controls, the patients showed increased and bilateral cerebral activations (p < .005) during the construction and elaboration phases. The prefrontal, temporal and posterior cerebral region activations were located within the core network sustaining AM, with the bilateral prefrontal region being centrally involved. The parametric neural responses to the difficulty of access and amount of details of memories were also significantly different for the two groups, with the right hippocampal region showing a particularly increased recruitment (p < .005). The findings suggested the presence of functional cerebral changes during AM performance and supported the presence of AM retrieval deficit in MS patients.  相似文献

This paper tries to show that Ferenczi's contributions in “The Development of Psychoanalysis” (with Otto Rank) and in his “Clinical Diary” are pivotal for the development of modern psychotherapy with severely disturbed patients. In addition, the question of whether a psychotherapeutic technique should or could be communicated to others is discussed.  相似文献

Abstract

This study examined differences in diabetes-specific locus of control beliefs of 82 insulin-treated Type I diabetes patients undergoing either conventional therapy (CT), intensified conventional therapy (ICT) or continuous subcutaneous insulin infusion (CSII). Compared to CT with its adherence to a strict regimen, ICT and CSII allow a much greater flexibility in timing of meals and daily activities. On the other hand, such flexibility requires a much more active role of the patient. The hypotheses of higher internality and lower powerful others locus of control beliefs in ICT and CSII patients than in CT patients could be supported for powerful others locus of control only. A one-year follow-up replicated this finding. Furthermore, high powerful others locus of control was associated with low diabetes-related knowledge and poor glycaemic control. The relevance of the patients' experience with the respective treatment is examined in view of the results and implications for studies on the feasibility of diabetes regimens are discussed.  相似文献

Recent studies indicate that depression is characterized by mood-congruent attention bias at later stages of information-processing. Moreover, depression has been associated with enhanced recall of negative information. The present study tested the coherence between attention and memory bias in dysphoria. Stable dysphoric (n = 41) and non-dysphoric (n = 41) undergraduates first performed a spatial cueing task that included negative, positive, and neutral words. Words were presented for 250 ms under conditions that allowed or prevented elaborate processing. Memory for the words presented in the cueing task was tested using incidental free recall. Dysphoric individuals exhibited an attention bias for negative words in the condition that allowed elaborate processing, with the attention bias for negative words predicting free recall of negative words. Results demonstrate the coherence of attention and memory bias in dysphoric individuals and provide suggestions on the influence of attention bias on further processing of negative material.  相似文献

时间加工是认知加工的内在属性。因此, 理解发生在知觉或更广泛的认知过程中的时间加工极为重要。为了应对中枢信息加工所面临的外部挑战, 大脑显然已形成了一些用于整合信息的特殊时间窗。已经发现, 其中一个时间窗介于数十毫秒的范围内, 它用于为意识活动产生必要的建构单元。来自反应时、时序阈限以及神经元结构振荡反应的研究为该时间窗的存在提供了实证证据。另一个时间窗的作用范围是2~3秒, 它用于产生“主观现在感”或作为使知觉体的标识保持不变的时间整合区间。支持该窗口存在的实验证据来自时距再现、两可图形、感觉运动同步以及神经生理学研究。还有一种时间窗以昼夜节律的形式存在。所有的心理和生理功能似乎都有着24小时的周期性变化。时间窗的紊乱会以神经或精神疾病的形式表现出来, 这恰恰表明了在基础研究之外对时间加工进行研究的重要性。  相似文献

Visual backward masking is a versatile tool for understanding principles and limitations of visual information processing in the human brain. However, the mechanisms underlying masking are still poorly understood. In the current contribution, the authors show that a structurally simple mathematical model can explain many spatial and temporal effects in visual masking, such as spatial layout effects on pattern masking and B-type masking. Specifically, the authors show that lateral excitation and inhibition on different length scales, in combination with the typical time scales, are capable of producing a rich, dynamic behavior that explains this multitude of masking phenomena in a single, biophysically motivated model.  相似文献
