期望反应模式是认知诊断分类的类中心,确定了诊断范围中属性及其层级关系后,类中心的数目由测验Q矩阵决定.类中心应该是完备的,即理论上有多少个知识状态就应该有多少个类中心,这涉及评分方式、Q矩阵设计、Q矩阵评价与修改、认知诊断测验如何实施等问题的讨论.重点给出多级评分认知诊断测验不同属性层级对应的完备Q矩阵设计的例子和罗列了Wang等人(2013)的Q矩阵修改的方法.  相似文献

认知诊断是近些年教育测量研究中的热点,大多数的认知诊断模型仅适用于0~1评分的情况.本文提出一种有多个潜变量多个滑动参数的多级评分认知诊断模型——GP-D1NA,只要由评分标准和知识状态能确定理想反应模式,就可以利用此方法进行认知诊断分析.在该方法中,我们给出项目滑动矩阵的概念,将被试的观测得分均看成由某个理想得分的滑动,并采用EM算法估计滑动矩阵.在模拟研究中,采用每掌握一个属性得1分的评分标准,结果表明线性型、收敛型、发散型、无结构型和独立型五种属性层级结构均有较高的判准率.  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 describes systems dynamics related to deep structure and development processes in human systems, to the process of arresting entropy or premature death in these systems and to the relationship between the cognition of deep structure, its outward manifestation and human systems viability and vitality. The paper proposes that inherent forces are present in systems that act to bring about alignment between inner deep structure and a system's manifested outer structures and processes, thereby enhancing viability and vitality. Deep structure is seen as a force toward self‐organization and rebirth.  相似文献

Two experiments employed Potential Performance Theory (PPT) to correct for inconsistency in a speeded task. In Experiment 1, a search task was employed whereby participants searched for a target letter among distracters. In Experiment 2, the search task was more complex and naturalistic—participants searched for enemy weapons in aerial photographs. Not surprisingly, the results revealed that longer search times led to greater accuracy. However, this improvement was due only in part to improved search strategies. Much, if not most, of the improvement was due to increased consistency. The authors demonstrate and discuss some of the advantages to be gained by considering a speeded task within the context of a clear and mathematically precise theory (PPT).  相似文献

Two conditional reasoning tests were administered to 34 students (17 males and 17 females) at each of four grade levels (i.e., 5th, 6th, 7th, and 8th). Both tests contained conditional reasoning arguments which assessed students' comprehension of five basic principles of inference. However, they varied systematically according to the sex typing of the content (i.e., masculine or feminine). The results indicated that there were no significant sex differences according to grade level, type of content, or principle of inference. On the other hand, at each grade level, there were consistent differences among the mean scores for the five principles, and valid principles were significantly easier than invalid principles. The implications of these findings for future research were discussed.  相似文献

Abstract

The preliminary results of an evaluation of a systematic assertiveness training programme (based on a cognitive-behavioural approach) in psychiatric care in Hungary are presented. The method adopted was specific to the Hungarian/Middle-European circumstances since people had difficulty in exercising their personal rights in the past. In groups of “neurotic” patients and comparison subjects three questionnaires (the Rathus-scale (R), the Assertiveness Inventory (AI) and the Uncertainty Questionnaire (UQ)) were administered at the beginning and at the end of the treatment. The training programme consisted of eight sessions with an emphasis on education about assertiveness and on the practice of skills such as saying “no” or standing up for oneself. A statistical analysis indicated significant improvement in the social skills of the participants, while an item analysis showed high internal consistency in all three questionnaires, and a concurrent validity analysis revealed a strong correlation between the Rathus-scale and the Assertiveness Inventory. The results indicate that assertiveness training can be used effectively in mental health care in Hungary.  相似文献

The research examines the structural bottleneck account and the resource account of the substantial dual-task deficits among older adults. Procedures from two common dual-task methodologies—the psychological refractory period and the relative-priority manipulation—were used to encourage maximization of the joint performance. Performance and time-sharing strategies from subjects between the ages of 20 and 70 years were examined. Age-related declines in time-sharing efficiency and in the precision of the executive control process were observed. The age-related effect was larger when two manual responses were required than when one manual and one vocal response were required, but no evidence for obligatory sequential processing was found. Except for the most demanding conditions, comparable practice effects were observed between the younger and older subjects, suggesting considerable cognitive plasticity in the older subjects. Implications for the two attentional accounts were discussed.  相似文献

The objective of the study was to investigate whether high and low intensity versions of cognitive behaviour therapy (CBT) might be an effective therapeutic approach for enhancing the mental health of Aboriginal Australians. Five university‐educated Aboriginal counsellors received in‐depth training in CBT. Over the following year, they used CBT strategies with their clients, and met 10 times as a participatory action research group. The group addressed three key questions: (a) Does CBT appear to be useful for Aboriginal Australians? (b) If so, what elements of CBT are perceived to be effective? (c) What adaptations might be made to CBT to enhance its effectiveness with Aboriginal Australians? The resulting qualitative data were transcribed and analysed. Counsellors perceived CBT to be very useful for their Aboriginal clients and for themselves. They reported that it enhanced their clients' well‐being, their own clinical skills, and their own well‐being, and it reduced burnout. The qualities of CBT that were perceived to be effective were its adaptability, pragmatic here‐and‐now approach, capacity for low‐intensity interventions, safe containing structure, promotion of self‐agency, and valuable techniques. It was suggested that the prime requirement for adaptations to CBT were that they would need to fit different social and cultural contexts.  相似文献
