光坪对同时性闪光信号辨认的影响

問題 如果在构成閃光的相互交替的亮与黑两个时相中,黑时相不是完全黑,而是亮度不同程度的变暗,人們照样能看出閃光。暗时相的光強可以低到零,这就是一般閃光;但其光強也可以象亮时相一样高,那就变成了固定灯光。我們把一切強度的暗时相統称为“光坪”或“坪”,而把亮吋相叫作“光峯”或“峯”。 关于光坪对閃光信号辨认的影响的問題,是有关业务部門提出来的。根据我們的現場調查,使用者对某些带光坪的閃光信号的試用反应良好。我們前一研究表明,在实驗給定条件下,不宜使用两个同时性閃光,作为类似該实驗所用編碼的信号;同时提出“不     

教学改革中促进学生掌握数学知識的一些心理因素

大跃进以来,教育革命在1958年取得胜利的基础上进一步深入到教学內容的改革中去,也就是說,根据“四个适当”的精神,对学校的制度、教材、教法等方面进行根本性的改革,因此中、小学数学教学体系改革也就提到日程上来了。但是一般人认为数学改革比较困难,原因是数学教材本身的系統性比較強,难以变动,同时中、小学生对数学学习感到最为困难,而提早学习是否为学生所能胜任,对此抱着怀疑的态度,所以要变动中、小学数学     

认知的自我指导技术对教师教学监控能力的影响

本研究采用认知的自我指导技术,对９名小学教师的教学监控能力进行训练。结果发现：训练不仅提高了教师教学监控能力,而且提高了教师对教学的认知水平,改善了教师的教学行为。     

Quality assurance in the clinical genetics setting—Report of a workshop

Participants in a panel discussion sponsored by thead hoc Quality Assurance Committee of the National Society of Genetic Counselors discuss early efforts to develop and implement quality assurance instruments at institutional, state, and regional levels. Uniform guidelines and self-assessment tools can help genetic counselors and clinical geneticists to provide the best possible care to individuals affected by genetic diseases. Further work will be needed to address aspects not covered here and to assure that guidelines allow for creative variation among professionals and centers. An interdisciplinary approach to such standard-setting is recommended.CGC     

Rhetorical theory and family therapy practice

The study found that a connection exists between rhetoric and therapy because both fields are interested in using language as a tool for generating change. Persuasion is viewed as inherent in human communication, even though people do not necessarily intentionally attempt to persuade others. Following a brief (but detailed) explanation of the theoretical stance which informs the implementation of rhetorical techniques in therapy, three pragmatic exemplars are offered to demonstrate the employment of two classical rhetorical concepts, the parastasis catalogue and syncrisis.The authors are grateful to Sandra Kodner, MS for her participation in the development of this project.     

Training in group-analytic psychotherapy in Europe

Group-analytic psychotherapy focuses on the making and maintaining of close, emotionally fulfilling relationships. Its practitioners attempt to fuse an individual and a whole-group perspective, and seek to provide the enabling conditions for freer communication between group members. The group-analytic approach is widely used in the United Kingdom, and many experiential groups on psychotherapy training courses are conducted on group-analytic lines. The Institute of Group Psychotherapy in London recognizes eight one-year courses in England and Scotland specifically oriented to group-analytic theory and methods. These courses provide an introduction to group psychotherapy to over 300 professionals of varied backgrounds every year. There are also two courses in the United Kingdom that provide a full training in group-analysis and group-analytic psychotherapy, and 11 courses on the continent of Europe. The number of courses is growing and there is now a European Group-Analytic Training Network providing formal links between them. Results of a postal survey indicate that few (10%) attenders at a one-year course have a negative response and that many (85%) recommend the course to colleagues. The efficiency and therefore reduced cost of group teaching and the incorporation of a group experience may be contributing factors to the increasing demand for this type of training.This paper is based on a presentation at an Open Session on Training in Group Psychotherapy: The Quest for a Viable Model at the American Group Psychotherapy Association Annual Meeting, Boston, February 1990. This paper represents the author's own views and is not an official statement of the Institute of Group Analysis [London]. However, members and staff of the Institute have made helpful contributions to the author in preparing it. He is especially grateful for the assistance of Mrs. Liesel Hearst (Chairperson, Overseas Training Sub-Committee, Institute of Group Analysis, London), Dr. Keith Hyde (Convenor, Manchester Course in Group Psychotherapy), Fr. Jim Christie (Convenor, Glasgow Course in Group Psychotherapy), and Dr. Vivienne Cohen (Chairperson, Training Committee, Institute of Group Analysis, London, in preparing this paper. The questionnaire study was conducted with the assistance of the Training Section of the North-Western Regional Health Authority.     

Does debt pressure lead to unethical behaviour intention? Evidence on aggregate and individual levels

Studies have shown that debt pressure impairs people's subjective well-being and social functioning, but few studies have examined its moral consequences. To explore the relationship between debt pressure and unethical behaviour intention, we conducted three studies and obtained aggregate-level (Study 1) and individual-level evidence (Studies 2 and 3). Study 1 analysed data on quarterly search volumes related to unethical behaviour intention on Baidu and quarterly measures of debt pressure in China, demonstrating that increased debt pressure predicted subsequent greater levels of unethical behaviour intention. Study 2 found that, compared with the control condition, individuals in the debt pressure condition exhibited greater unethical behaviour intention. Study 3 further tested the mediating role of self-control and showed that individuals under high debt pressure evinced diminished self-control and, in turn, displayed more unethical behaviour intention.     

预测性对快速读者和慢速读者词汇加工的影响

本研究借助眼动仪通过两个实验考察了熟练阅读中快速读者与慢速读者对语境预测性的利用是否有差异。实验1比较快速组与慢速组在中央凹加工高、低预测词的差异。实验2对比两组读者利用副中央凹预视(相同、相似假字、低预测词和不相似假字)加工高预测词的差异。实验1结果显示两组读者有相似的预测性效应：对高预测词的注视时间比低预测词更短。实验2结果显示两组读者的预视效应存在差异：慢速组在相同预视下对目标词的跳读率高于低预测预视,而快速组在这两种预视下的跳读率差异不明显但高于慢速组;慢速组在低预测和不相似预视下注视目标词的时间分别长于相同预视,而快速组的这两种效应较小。结果表明,两组读者利用预测性的差异表现在副中央凹加工阶段,即慢速读者比快速读者利用相似预视激活预测性信息的效率更低,且在低预测或无效预视下对词汇的识别和语义整合更困难,这说明慢速读者在词汇加工中更依赖语境且对无关信息的抑制更弱。这些结果支持词汇质量假说。     

怀旧的触发、研究范式及测量

怀旧指的是个体怀念过去的事物、人物、地方甚至经历或感受。它大多与美好的记忆联系在一起, 并会带来积极的情绪体验, 但同时可能也会引起消极的情绪体验。怀旧对维持个体身心健康有一定的积极效用。本文着重介绍了怀旧的触发因素包括客观刺激的视觉、嗅觉、听觉及主观刺激的消极情绪与低温知觉, 分析了其研究范式有质化研究(内容分析与扎根理论)、量化研究(问卷调查与经验取样法)和实验研究(单因素随机实验设计与多因素实验设计), 并介绍了其相关的测量工具。未来研究要加强主动怀旧与被动怀旧、积极怀旧与消极怀旧的探讨; 整合各种研究范式与强化纵向的追踪研究; 以及要区分特质型怀旧与状态型怀旧。
