Evidence has accumulated for information processing deficits in schizophrenia. The functional significance of these deficits is only beginning to be understood. There are indications that these deficits may respond to intervention. Training on deficient functions has been demonstrated to relate to improvements in performance. A treatment program of cognitive rehabilitation is deduced from the literature and induced from clinical experience. The treatment is designed to impact directly on the information processing deficits of schizophrenic patients and indirectly to ameliorate functional deficits.  相似文献

计划-注意-同时性加工-继时性加工,这些基本PASS概念的提出,是为了给传统上将智力作为一个笼统构念的做法提供某种替代的选择。在这一新的理论途径中,我将一般能力分解为对主要认知过程的研究,其中每个认知过程均有其行为、认知和神经心理成分,而且重要的是,每个认知过程均有相应的一组评估测量任务。PASS模型,这一理论框架能够充分包容体现于教育和组织行为中的广泛一系列认知功能。  相似文献

The authors examined the relationship between body dissatisfaction and self-image across the life span. A sample of 106 women between the ages of 20 and 65 years completed questionnaire measures of body dissatisfaction, body importance, cognitive control over the body, self-concept, and self-esteem. The authors found that body dissatisfaction and body importance did not differ among the groups of women who were younger, middle aged, and older. Although body dissatisfaction was related to self-concept and self-esteem for the entire sample, the strength of that relationship reduced with increasing age and increasing perceptions of cognitive control. The authors concluded that the cognitive strategies of women who were older protect their self-concept and self-esteem from the influence of body dissatisfaction.  相似文献

上世纪80年代以来,随着经典认知研究的步履维艰,认知研究逐渐显示出具身化的特点。具身认知是第二代认知科学的代表,它强调身体在认知形成中的重要性,认为身体对认知有限制、分配和调节作用,并具有与经典认知不同的运动观。近年来研究者们以实验手段力求为具身认知的存在提供证据,着力考察认知与身体感知运动状态的相互影响。具身认知理论在认知构建、生态效度等方面具有自己的优势,但目前具身认知还是一个新兴的研究领域,有待进一步的深入探讨。  相似文献

认知负荷理论在教学设计中的应用及其启示   总被引:11,自引:0,他引:11

在教学设计中,认知负荷理论有助于激励学习者的学习活动、使之表现出良好的学习绩效。认知负荷理论主要依赖于以容量有限的工作记忆为核心的认知结构的支持。工作记忆包括相对独立的视觉、听觉信息加工单元,同时又与容量较大的长时记忆共同承担着对信息的贮存与理解。根据该理论,可以通过把多个信息单元编码成一个完整的认知图式,或通过自动化加工规则,或使用多媒介(多感觉通路)呈现形式等多种方法来设法规避工作记忆的有限性。此文总结了可通过样例学习增加适当的认知负荷的教育技巧,样例一精细化训练对于降低认知干扰及超负荷的影响,样例对学习者的认知负荷的影响,以认知负荷理论为基础的教学设计原则,以及基于认知负荷理论研发的教学设计在各方面业已取得的进展及其存在的问题与可能的发展趋势。  相似文献

Cognitive neuroscience of aging: contributions of functional neuroimaging   总被引:10,自引:0,他引:10  
By revealing how brain activity during cognitive performance changes as a function of aging, studies using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) are contributing to the development of a new discipline of Cognitive Neuroscience of Aging. This article reviews functional neuroimaging studies of cognitive aging in the domains of visual perception, episodic memory encoding and semantic memory retrieval, episodic memory retrieval, implicit memory, and working memory. The most consistent finding of these studies was that brain activity tends to be less lateralized in older adults than in younger adults. This finding is conceptualized in terms of a model called Hemispheric Asymmetry Reduction in Old Adults (HAROLD). According to a compensation hypothesis, bihemispheric involvement could help counteract age-related neurocognitive decline, whereas, according to a dedifferentiation hypothesis, it reflects a difficulty in recruiting specialized neural mechanisms.  相似文献

The clinical and cost-effectiveness of a computer-aided cognitive behavioural therapy (CCBT) programme, Beating the Blues, is indicated by a number of studies, but relatively little is known about its acceptability for patients with depression, anxiety, or both. This study investigated the acceptability of Beating the Blues offered on eight scheduled clinic visits with brief face-to-face support. Pre and posttreatment measures explored the relationship among programme acceptability, treatment continuation, and outcomes for people accessing the programme in routine care. Two hundred and nineteen patients with depression, anxiety, or both were offered Beating the Blues in 11 primary and secondary care practices. One hundred and ninety-one (87%) completed the pretreatment measures and 84 (38%) completed a treatment feedback questionnaire. Analysis of treatment acceptability for CCBT indicated a positive patient experience with the programme. Pretreatment expectancies predicted CCBT treatment completion but not outcomes. No differences were found between men and women on pretreatment measures. Posttreatment, women reported more favourable responses to the therapy, finding the programme more helpful and more satisfactory, than did men. No relationship between treatment acceptability and age was found. Study limitations, including research methods and attrition rates, and implications for future research are discussed. It is concluded that the Beating the Blues CCBT programme is an acceptable treatment for common mental health problems in routine care.  相似文献

This paper presents a series of five studies conducted between the year 1994 and the year 2000. A common goal shared by all five studies is to validate the Perry scheme as measured by the Zhang Cognitive Development Inventory. Involved in the studies were 2,269 (937 males, 1321 females, and 11 did not indicate gender) students from 12 universities in three cultures. All research participants responded to the Zhang Cognitive Development Inventory. Participants from one of the studies also responded to the Study Process Questionnaire. Still, participants from another one of the studies also responded to the Thinking Styles Inventory. Three of the major findings are: (1) the Zhang Cognitive Development Inventory has reasonably good reliability and good internal and external validity, (2) the cognitive-developmental pattern of the mainland Chinese students was opposite to that described by Perry, and (3) the cognitive-developmental pattern described by Perry was not identified in either of the two U.S. samples. Recommendations were made as they relate to future studies using the Zhang Cognitive Development Inventory.  相似文献

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明:(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用:在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。  相似文献

This pilot study aimed to explore the clinical outcomes and therapeutic relationship for clients of an adult mental health service using Beating the Blues, a computerised cognitive behaviour therapy (CCBT) package. Sixteen participants completed the programme and reported a significant reduction in Beck Depression Inventory scores posttreatment. Participants' mean item ratings on the relationship measure were above the neutral midpoint, but no association was found between the therapeutic relationship and outcome. The results are discussed in terms of the utility of CCBT as part of a stepped-care model and how further research might usefully explore the nature of the relationship formed between clients and CCBT programmes.  相似文献

The current review presents a theory-guided review of the existing cognitive behavioral therapy (CBT) interventions for attention-deficit/hyperactivity disorder (ADHD) in college students. Across the eight studies that investigated this topic, moderate reductions were shown in inattentive symptoms but little to no change was reported in hyperactive/impulsive symptoms. Results indicated a moderate treatment effect on self-reported quality of life and school/work functioning, yet less of an impact on GPA, response inhibition, social functioning, and executive functioning. Methodological and statistical problems and inconsistencies were noted. Since college students are emerging adults, it is likely that the optimum CBT intervention for college students with ADHD lies somewhere in between the existing clinic-based adult ADHD CBT interventions as well as the school-based adolescent ADHD psychosocial interventions. Directions for future research and recommendations for clinicians in university settings are provided in an attempt to further develop the existing college students CBT clinical research evidence base.  相似文献

For the past 30 years, generations of scholars of cognitive behavior therapy (CBT) have expressed concern that clinical practice has abandoned the close links with theory that characterized the earliest days of the field. There is also a widespread assumption that a greater working knowledge of theory will lead to better clinical outcomes, although there is currently very little hard evidence to support this claim. We suggest that the rise of so-called “third generation” models of CBT over the past decade, along with the dissemination of statistical innovations among psychotherapy researchers, have given new life to this old issue. We argue that theory likely does matter to clinical outcomes, and we outline the future research that would be needed to address this conjecture.  相似文献

Inconsistent alertness and orientation (sluggishness, drowsiness, daydreaming) were reported to accompany Attention Deficit Disorder (ADD) without Hyperactivity in DSM-III. Such Sluggish Cognitive Tempo items were tested in the DSM-IV Field Trial for ADHD, but were discarded from the Inattention symptom list because of poor negative predictive power. Using 692 children referred to a pediatric subspecialty clinic for ADHD, Sluggish Tempo items were re-evaluated. When Hyperactivity–Impulsivity was absent (i.e., using only cases of Inattentive Type plus clinic controls), Sluggish Tempo items showed substantially improved utility as symptoms of Inattention. Factor analyses distinguished a Sluggish Tempo factor from an Inattention factor. When DSM-IV ADHD types were compared, Inattentive Type was uniquely elevated on Sluggish Tempo. These findings suggest that (a) Sluggish Tempo items are adequate symptoms for Inattentive Type, or (b) Sluggish Tempo may distinguish two subtypes of Inattentive Type. Either conclusion is incompatible with ADHD nosology in DSM-IV.  相似文献

Pathological gambling is a widespread problem with major implications for society and the individual. There are effective treatments, but little is known about the relative effectiveness of different treatments. The aim of this study was to test the effectiveness of motivational interviewing, cognitive behavioral group therapy, and a no-treatment control (wait-list) in the treatment of pathological gambling. This was done in a randomized controlled trial at an outpatient dependency clinic at Karolinska Institute (Stockholm, Sweden). A total of 150 primarily self-recruited patients with current gambling problems or pathological gambling according to an NORC DSM-IV screen for gambling problems were randomized to four individual sessions of motivational interviewing (MI), eight sessions of cognitive behavioral group therapy (CBGT), or a no-treatment wait-list control. Gambling-related measures derived from timeline follow-back as well as general levels of anxiety and depression were administered at baseline, termination, and 6 and 12 months posttermination. Treatment showed superiority in some areas over the no-treatment control in the short term, including the primary outcome measure. No differences were found between MI and CBGT at any point in time. Instead, both MI and CBGT produced significant within-group decreases on most outcome measures up to the 12-month follow-up. Both forms of intervention are promising treatments, but there is room for improvement in terms of both outcome and compliance.  相似文献

The current study examined the effectiveness of brief cognitive behavior therapy (CBT) for severe mood disorders in an acute naturalistic setting. The sample included 951 individuals with either major depressive disorder (n = 857) or bipolar disorder with depressed mood (n = 94). Participants completed a battery of self-report measures assessing depression, overall well-being, and a range of secondary outcomes both before and after treatment. We found significant reductions in depressive symptoms, worry, self-harm, emotional lability, and substance abuse, as well as significant improvements in well-being and interpersonal relationships, post-treatment. Comparable to outpatient studies, 30% of the sample evidenced recovery from depression. Comparison of findings to benchmark studies indicated that, although the current sample started treatment with severe depressive symptoms and were in treatment for average of only 10 days, the overall magnitude of symptom improvement was similar to that of randomized controlled trials. Limitations of the study include a lack of control group, a limitation of most naturalistic studies. These findings indicate that interventions developed in controlled research settings on the efficacy of CBT can be transported to naturalistic, “real world” settings, and that brief CBT delivered in a partial hospital program is effective for many patients with severe depressive symptoms.  相似文献
