从耗散理论解读肿瘤的发病及治疗   总被引:1,自引:0,他引:1  
肿瘤的综合治疗方案,即药物-社会-心理治疗已广泛地应用于临床,虽效果显著,但其机制尚缺乏确切的实验依据。笔者从耗散结构理论来解读这种综合疗法,认为药物、社会及心理治疗均是通过增加机体的负熵,使肿瘤患者的内环境处于有序平衡状态而改善其病情。从耗散理论出发可以将肿瘤的综合疗法更好地应用于临床。  相似文献

采用信息加工视角, 在划分不同信息来源的基础上分析编码、存储(巩固)、再激活/再巩固和提取的一系列加工过程如何导致错误记忆形成, 由此总结出错误记忆产生的三个可能原因:(1)因缺乏针对目标事物特异性细节的记忆表征而侧重于编码和提取目标和非目标事物共享的抽象记忆表征, 使被试更倾向于依赖抽象表征对缺失的目标细节进行重构, 引发错误记忆; (2)目标事物启动了对应图式, 导致与图式相关的非目标事物记忆表征得到增强, 引发错误记忆; (3)误导信息干扰了再度激活状态下目标事物的记忆表征, 妨碍其进行准确的记忆再巩固, 从而引发错误记忆。未来研究可进一步探讨目标事物特异性细节的表征区域、不同类型的图式表征促进非目标事物记忆表征的具体机制以及提取阶段的图式复现对错误记忆形成的影响等问题。  相似文献

该研究探讨被试的认知风格、源问题结构的清晰度及两个源问题间内容的相似性三者对图式归纳和类比迁移的影响。实验采用2×2×2的三因素完全随机设计。结果显示:(1)源问题图式表征的质量受到被试认知风格和源问题结构的清晰度两个变量的影响;(2)类比迁移的成绩只受到源问题结构清晰度的影响;(3)结构清晰的条件下,两类被试图式表征的质量无明显差异;结构不清晰的条件下,两类被试图式表征的质量出现明显差异。  相似文献

When reasoning counterfactually, we think of alternative possibilities to what we know to be true about the world by imagining what would have happened had a situation been different. Research has yielded mixed findings and substantial debate over when this ability develops, how it is best conceptualized, and what functions it serves. In this article, we propose a framework of counterfactual reasoning in development. We argue that counterfactual reasoning is best understood by looking both at the representations of reality children manipulate counterfactually, and the cognitive processes that make up and contribute to counterfactual reasoning. In so doing, we highlight the fact that many of the component skills are present in early childhood. This framework yields testable predictions about children’s counterfactual reasoning across a range of situations. We also discuss recent work that examines the contribution of counterfactual reasoning to learning in childhood.  相似文献

家庭暴力已成为一个世界性的社会问题,然而我国学者对家庭暴力的研究多集中在现象的描述,原因的探讨和完善立法等方面,因而从社会心理学角度探究家庭暴力的认知机制对揭示家庭暴力的实质具有重要意义。心理学研究指出家庭暴力的产生及其对子女的影响而导致的暴力轮回都是认知结构上的偏差所导致,所以从改变认知结构入手的认知行为疗法将是防止家庭暴力的直接和有效的策略。  相似文献

A percept-genetic test of defence mechanisms (the Meta-Contrast Technique) was given to 169 undergraduate students. Subjects were divided into three groups: two visual half-field groups and one group tested in the regular way. It was hypothesized that the visual field groups would differ from one another and from the control group. An ANOVA showed that the left and right visual half-field conditions differed significantly, as hypothesized. Clear regressive signs were more common in the left visual half-field group, whereas isolation and repression were more common in the right. Furthermore, the visual half-field conditions differed in certain respects from the control group. It was concluded that processes in both hemispheres are important for complex psychological functions.  相似文献

Borderline personality disorder (BPD) is a relatively common and severe psychiatric disorder that can impair quality of life in many ways. The aim of this study was to determine whether a combined treatment model for BPD patients, utilising major principles from schema‐focused therapy (SFT) and dialectical behavioral therapy (DBT), could be more effective in relieving early maladaptive schemas of BPD patients, compared to treatment as usual (TAU). This study is a part of the Oulu BPD study conducted at mental health care services run by Oulu city social and health care services. The study is a multisite, randomized controlled trial conducted over a one year period, involving two groups of patients with severe BPD: (1) Community Treatment By Experts (CTBE) patients (n = 18) receiving the combined treatment model, and 2) TAU patients (n = 27). The patients' schemas were assessed using the Young Schema Questionnaire (YSQ‐L3a) before and after one year of treatment. The results reveal that CTBE patients who attended the combined treatment model showed a statistically significant reduction in eight out of 18 early maladaptive schemas, while patients receiving treatment as usual did not demonstrate any significant changes in schemas. The cognitive therapeutic treatment model can be applied for clinical use in public mental health settings using existing professionals, and appears to produce positive changes in patients with BPD.  相似文献

评价除了了解学习者的学习情况外,同时还应该提供学习者学习状况的诊断信息,以利于教学与学习。评价应该以认知心理学对学习过程的研究,作为编制测验的实质理论依据,进行认知诊断评估。本文针对认知诊断的心理学基础:知识的习得、知识诱发、知识表征、知识结构等进行梳理,以便测验开发者对认知诊断评估有更清晰的认识。  相似文献

Kragh's Defence Mechanism Test has proved its worth in a number of applied settings but has hitherto required skilled time-consuming interpretation. Two studies are reported which validate an "objectively scored" version of the test developed using G-analysis. In the first, it was found that this version of the test could successfully predict the performance of trainee pilots. The second study examined the construct validity of this version of the test. It was found that the predictive factor from Study I re-emerged within a sample of students, where it correlated positively with scores on a test of perceptual defence and the Shrewdness (N) scale of the 16PF, and negatively with two of the identification scales of the Defence Mechanism Test. This factor was tentatively identified as one of general defensiveness. It is concluded that this form of the test deserves consideration when selecting individuals for stressful occupations.  相似文献

视觉化表征是代数应用题表征的一大类型, 在问题解决过程中起着重要作用。视觉化表征的理论主要有视觉-逻辑二维模型、理解-转换模型、表象表征理论和图式-图像表征论, 四种理论模型各有其特殊的方法学意义。代数应用题的视觉化表征主要受到题目视觉化程度和认知负载等刺激因素以及自我效能感等认知因素的影响, 最后, 本文指出了在代数应用题视觉化表征理论、研究方法和影响因素探索中的进步以及发展空间。  相似文献

Kragh ( Scandinavian Journal of Psychology , 1998, 39, 123–124) criticises a recent empirical study of the Defence Mechanism Test (DMT) conducted by the present authors (Zuber & Ekehammar, 1997) concerning methodological and other shortcomings. The present paper reviews and responds to Kragh's critical points. As to the most serious criticism, the methodological, the main conclusion is that Kragh's own published empirical studies of the DMT, and also those of other researchers, can be criticised along similar lines. Furthermore, and surprisingly, in contrast to our study, Kragh's main DMT studies do not employ the DMT picture(s) at all.  相似文献

A paper by I. Zuber and B. Ekehammar in this Journal (38, 1997) is reviewed. The paper advocates that the non-veridical contents in the series of reports in the DMT should preferably be referred, not to psychoanalytic defence mechanisms, but to factors of stimulus order. The methods and the arguments of this investigation are critically examined.  相似文献

教学心理学情感维度上的一种教材处理策略——心理匹配   总被引:24,自引:1,他引:24  
卢家楣 《心理科学》1998,21(6):506-510
在教学心理学领域中,人们往往习惯于从认知维度探索教材的优化处理策略,缺乏情感维度上的相应研究。奥苏贝尔虽提出意义学习的两个内在先决条件:一是学习者有同化新材料的认知结构;二是学习者有意义学习的心向.但他本人也仅从影响学生认知结构的角度,提出教材的认知处理策略──先行组织者策略.而未从影响学生心向的角度.提出教材的情感处理策略。鉴此,本文从情感维度上提出教材处理的心理匹配策略.以冀与认知策略一起共同优化处理教材、呈现教学内容环节,并阐明心理匹配策略的内涵、机制、作用和种类。  相似文献

对心理表征问题进行自然的解释是至关重要的,但这方面的研究都是建立在有关概念和命题表征的预设的基础之上的,所以有必要弄清概念表征和命题表征的哲学解释;联结主义也对心理表征问题作了解释,根据被表征的是什么以及通过什么来表征的原则,联结主义网络主要通过四种方式对概念和命题进行表征。总的来说,联结主义对概念和命题的表征与它们的哲学解释并不是一一对应的,其方法论基础是费耶阿本德的多元方法论,即"怎么都行"。  相似文献

空间图式加工促进方向性时间表述的理解   总被引:1,自引:1,他引:1  
吴念阳  徐凝婷  张琰 《心理科学》2007,30(4):853-856
时间表征是否具有空间方向性?本研究通过考察66名研究生时间表述实时加工中的空间引导效应来回答这个问题。实验一表明:空间垂直方向性图式促进被试加工含有空间词汇的时间表述;实验二表明:两种空间方向性图式,即水平方向性图式和垂直方向性图式,都促进被试加工含有纯时问词汇的时间表述。实验结果证实了时间表征具有空间方向性,并为“抽象思维以感知一动觉经验为基础”这一论点提供心理学证据。  相似文献

动词论元结构复杂性表现在论元数量、论元范畴选择模式、题元角色指派模式和映射方式四个方面。大部分实证研究表明,更多的论元数量、选择性论元范畴、选择性题元角色指派以及非典型映射,使动词论元结构加工的认知神经机制更复杂。多论元加工功能脑区主要涉及左侧额下回和外侧裂周后部;选择性论元范畴加工功能脑区主要涉及左侧额下回、额叶中后部、颞上回和颞叶中后部;选择性题元角色指派加工功能脑区主要涉及外侧裂周后部、左侧额叶中后部和额下回;非典型映射加工功能脑区主要涉及左侧额下回、颞上回、颞中回和颞叶后部。左侧额下回可能涉及初始句法加工、动词次范畴确定、句法移位和非宾格动词语义加工,左侧额叶中后部可能涉及初始句法加工和动词次范畴确定,左侧颞上回和颞叶中后部可能涉及表层句法加工和表层论元句法-语义整合,外侧裂周后部可能涉及论元语义表征。动词论元结构加工过程和动词词汇特征表明,复杂性某些方面存在交互作用。动词论元结构复杂性与加工难易的对应关系、复杂性加工难度层级和交互作用的认知神经机制以及汉语动词论元结构复杂性加工认知神经机制等议题,有待进一步探讨。  相似文献

数字空间表征是人类对数字进行表征的重要方式。数形联觉(number-form synesthesia)是一种数字可以有意识地引起空间知觉的独特现象,与此类似的是非联觉者中广泛存在的无意识的心理数字线(mental number line)现象。两者在行为和脑机制上存在着很多重叠,也存在着值得思考的差异。数形联觉的研究能够提供实质性的行为和脑机制数据,用以解决数字空间表征研究中出现的问题,加强对于数字空间表征的理解;也为更加全面深入地开展进一步研究提供了新的启示,成为数字空间表征研究中值得推崇的新取向。  相似文献

预见:情景记忆的未来投射与重构   总被引:1,自引:0,他引:1       下载免费PDF全文
预见是对有关个人的未来事件进行模拟的过程。相关的研究从几个方面展开:从比较心理学的角度探讨预见能力的种系发生图谱,从发展心理学的角度考察预见能力的发生发展状况,从认知神经科学的角度揭示预见过程的认知机制和神经基础。未来的研究应该补充和修正预见能力的种系发生图谱,揭示发展过程中预见能力与其他能力的关系,进一步考察卷入预见过程脑区之间的特定神经通路,并提高和拓展其社会应用的价值和范围。  相似文献
