轻度阿尔茨海默症往往伴随着不同程度的前瞻记忆衰退。已有研究以轻度阿尔茨海默症与前瞻记忆衰退的关联程度为主线, 对比了这一关联与“其他认知缺陷疾病-前瞻记忆衰退”、“轻度阿尔茨海默症-回溯记忆衰退”以及“轻度阿尔茨海默症-遗传表达”这三种关联的类似程度。此外, 也有研究涉及到了如何促进轻度阿尔茨海默症患者的前瞻记忆。将来的研究应引入病情程度、前瞻记忆任务类型等变量, 深入探讨轻度阿尔茨海默症与前瞻记忆衰退的关联, 并使用ERP、fMRI等神经生理技术确定轻度阿尔茨海默症患者前瞻记忆衰退的机制。 相似文献

为了探讨初中生亲子依恋、同伴依恋对其主观幸福感的影响以及集体自尊和个体自尊在两者之间所起的中介作用,本研究采用问卷调查的方法对两所初中学校的857名初一至初三的学生进行了调查.主要结果如下:(1)总体而言,男生的父子依恋水平、集体自尊水平和生活满意度更高,女生的同伴依恋水平和消极情绪更高;(2)男女生表现出不同的年级发展特点,女生在亲子依恋、集体自尊和消极情绪,男生在集体自尊上表现出明显的初二现象;(3)亲子依恋、同伴依恋水平越高,初中生的集体自尊和个体自尊水平越高,其主观幸福感程度也越强;(4)母子依恋、同伴依恋、个体自尊和父子依恋依次显著正向预测初中生的生活满意度,并依次负向预测初中生的消极情绪;同伴依恋、个体自尊、母子依恋和集体自尊依次显著正向预测初中生的积极情绪;(5)亲子、同伴依恋不仅能直接影响初中生的主观幸福感,而且通过两种途径(依恋→集体自尊→主观幸福感;依恋→集体自尊→个体自尊→主观幸福感)间接对其产生影响. 相似文献

Eighteen healthy young adults underwent event-related (ER) functional magnetic resonance imaging (fMRI) of the brain while performing a visual category learning task. The specific category learning task required subjects to extract the rules that guide classification of quasi-random patterns of dots into categories. Following each classification choice, visual feedback was presented. The average hemodynamic response was calculated across the eighteen subjects to identify the separate networks associated with both classification and feedback. Random-effects analyses identified the different networks implicated during the classification and feedback phases of each trial. The regions included prefrontal cortex, frontal eye fields, supplementary motor and eye fields, thalamus, caudate, superior and inferior parietal lobules, and areas within visual cortex. The differences between classification and feedback were identified as (i) overall higher volumes and signal intensities during classification as compared to feedback, (ii) involvement of the thalamus and superior parietal regions during the classification phase of each trial, and (iii) differential involvement of the caudate head during feedback. The effects of learning were then evaluated for both classification and feedback. Early in learning, subjects showed increased activation in the hippocampal regions during classification and activation in the heads of the caudate nuclei during the corresponding feedback phases. The findings suggest that early stages of prototype-distortion learning are characterized by networks previously associated with strategies of explicit memory and hypothesis testing. However as learning progresses the networks change. This finding suggests that the cognitive strategies also change during prototype-distortion learning. 相似文献

This study investigated developmental differences in story recall in children with attention-deficit/hyperactivity disorder
(ADHD), N = 57 (77.2% male) and their comparison peers, N = 98 (61.2% male). Children at the ages of 4–6 or 7–9 completed a free recall immediately after viewing each of two televised
stories, once in the presence of toys during viewing and once in their absence. This procedure was repeated with new stories
21 months later. Comparison children recalled more story events and showed a greater sensitivity to the thematic importance
of the story events than did children with ADHD, a pattern that remained stable over time. Older comparison children showed
a dramatic increase over time in the global coherence of their narrations, whereas the older children with ADHD showed limited
improvement over time. The implications of these findings for academic performance and the possible need for remediation are
discussed. 相似文献

人与自然和谐的道德基础——古代"天人合一"思想的现代生态伦理启示 总被引:4,自引:0,他引:4
人与自然的和谐有着道德基础。古代的“天人合一”思想为我们从道德的视角研究人与自然的和谐,以及建构现代生态伦理观提供了一定的帮助。从道德的意义上,人与自然的和谐中人是道德主体,承担着全部道德责任,其行为是道德评价的对象。人对自然的适应与改造、尊重与利用是辩证的统一。 相似文献

尽管近年来在慢性心力衰竭(CHF)的治疗方面取得了较大的进展,但CHF患者仍有较高的住院率及病死率.CHF临床实践指南的发布促进了规范化治疗.为了取得良好的医疗效果,临床医生必须对心力衰竭患者提供一系列复杂的药物治疗及严格的自我控制措施.随着医学的不断发展,出现了包括心脏再同步化起搏、左心室辅助装置或心脏移植等治疗,而这些手段常需要在对患者进行危险性评估的基础上进行.严格遵循指南并使CHF患者出院后的教育与各种支持项目相结合才能够在一定程度上减低患者的再住院率及病死率. 相似文献

This paper distinguishes between the grammar of wishes in neurotic patients and the grammar of imperative needs in borderline patients. The treatment of a borderline psychotic boy 30 years ago was uninformed by subsequent developments in technique arising from the theory of projective identification as a communication rather than as an attack or a defense. Issues that need addressing in borderline patients, especially those who are children, include (a) developmental delay, (b) the distinction between defenses and overcomings in the paranoid position, (c) rectification fantasies of vengeance, and (d) rectification fantasies of justice and other moral imperatives. 相似文献

In normal vision, the various “gestalt-free” combinations which form early in a percept, are repressed by the emergence of the veridical composite perception; but in schizophrenic vision, with its inadequate repressive powers, the early combinations emerge as the completed composite. This completed composite, if at all veridical, is so only partially. Rorschach studies support the idea of a range of perceptual abortions among schizophrenics, varying directly with the process-reactive range. 相似文献
