国外儿童科学思维发展的新探索

儿童科学思维是发展心理学研究领域的重要的研究课题。最近十年,儿童科学思维发展的研究经历了显著的变化。文章对儿童科学思维发展的研究进行简要回顾,主要阐述有关儿童科学思维发展的特殊领域知识、一般领域策略、概念和策略的整合模型以及微观发生法,并在此基础上,对儿童科学思维发展研究进行简单的评价和展望。     

心理学视角下的人生目标

从心理学视角对人生目标予以研究非常重要。目前, 对此的一系列研究进展显示：在概念上, 尽管不同研究者对人生目标的认识存在差异, 但却一致同意它是一种能持续地赋予人生以方向和意义的动机性概念; 在对人生目标的测量上, 主要关注于“人生目标感”的高低程度及人生目标的内容两方面; 对人生目标功能的研究显示, 高人生目标感与更好的压力应对、健康行为及身心状态相联系, 但不同内容类型的人生目标是否存在功能差异尚需探讨; 在影响因素上, 影响人生目标感高低和人生目标内容的因素十分复杂, 大体可划分为个体因素和环境因素两类。进一步的研究需继续澄清概念、完善测量体系并系统化相关研究, 并应考虑相关文化差异问题, 以更好服务于人生目标的培育工作。     

工作场所不文明行为受害者向实施者反转的机制

梳理和归纳了导致工作场所不文明行为的受害者反转为实施者的组织事件, 包括团队层次的不作为领导行为和领导不文明行为以及个体层次的同事不文明行为。借助事件系统理论对受害者反转为实施者的认知过程进行了说明, 如果组织事件的强度足够引起受害者的控制化信息加工, 则其可能改变自己的原有行为进而实施工作场所不文明行为; 根据社会信息加工理论, 受害者的控制化信息加工可以通过三条路径实现, 即学习过程, 归因过程和道德判断过程。建议未来研究进一步探讨情绪和认知两者在不文明行为受害者角色反转中的作用, 以及工作领域之外的因素在其中的作用, 并且能够使用日记研究法进行验证; 未来研究还可以探讨工作场所不文明行为的旁观者反转为实施者的机制。     

定向遗忘条件下DRM词的加工深度和情境对错误记忆的影响*

在定向遗忘条件下探讨DRM词加工时产生的错误记忆现象,并探究造成这一现象的深层原因。实验一和实验二分别操纵了词的深、浅加工以及词所处的情境。实验一的结果发现只在深加工时,F指令下的DRM词受到抑制激活,低于R指令下的再认正确率,关键诱词的错误再认也与各指令下DRM词的恢复提取密切相关;实验二的结果发现集中情境和随机情境均会受到遗忘指令的影响抑制DRM词的正确再认,但集中情境下关键诱词的错误再认与各指令下DRM词的恢复提取关联更紧密。在定向遗忘条件下,用FTT理论解释实验一的结果较为合理,用AAT理论解释实验二的结果较为合理。     

吸毒者心理社会生活质量分析

本研究旨在考察吸毒者的心理社会生活质量。云南地区194名吸毒者和198名正常被试参与了此项研究。结果表明：1)吸毒者和正常人在幸福感、自尊感、社会交往焦虑感、无力感、无意义感等方面都有显著差异,吸毒者的心理社会生活健康质量较差;2)不同性别、从事不同工作、兄弟姐妹数目和父母教育水平不同的吸毒者的心理社会生活质量不同;3)首次吸毒和复吸的大多数原因是心理因素。本研究对有关结果对吸毒者戒毒及教育的指导意义进行了讨论。     

SUN: Top-down saliency using natural statistics

When people try to find particular objects in natural scenes they make extensive use of knowledge about how and where objects tend to appear in a scene. Although many forms of such "top-down" knowledge have been incorporated into saliency map models of visual search, surprisingly, the role of object appearance has been infrequently investigated. Here we present an appearance-based saliency model derived in a Bayesian framework. We compare our approach with both bottom-up saliency algorithms as well as the state-of-the-art Contextual Guidance model of Torralba et al. (2006) at predicting human fixations. Although both top-down approaches use very different types of information, they achieve similar performance; each substantially better than the purely bottom-up models. Our experiments reveal that a simple model of object appearance can predict human fixations quite well, even making the same mistakes as people.     

The promises and perils of pragmatism: commentary on Fins, Bacchetta, and Miller

Fins, Bacchetta, and Miller's clinical pragmatism has several appealing features: an emphasis on dialogue, a commitment to consensus, a focus on particular individuals rather than persons in general, and a strong interest in the process as well as the product of moral decision making. Nevertheless, for all its protests to the contrary, clinical pragmatism has a tendency to privilege medical facts over nonmedical values, to conflate appropriate medical decisions with right moral decisions, and to conceive problems at the bedside in terms of "getting" patients and families to "go along" with the treatment plans of clinicians. In sum, there is within clinical pragmatism the potential for physicians to take back some of the power they ceded to patients during the height of the patients' rights and autonomy movement. Provided that clinicians guard against the temptation to use clinical pragmatism manipulatively, however, the method promises, more than most other methods of moral problem solving, to help increasingly diverse individuals make good moral decisions about patients' care under conditions of enormous uncertainty.     

The use of ecological momentary assessment to test appraisal theories of emotion

Although appraisal theories have received strong empirical support, there are methodological concerns about the research, including biased recall, heuristic responding, ethical issues, and weak and unrealistic induction of emotions in laboratories. To provide a more ecologically valid test of appraisal theories, the authors used ecological momentary assessment, in which the emotions and appraisals of Singaporean police officers were measured online over the course of an ordinary workday. The research focused on happiness. Support was obtained for predictions, demonstrating the generalizability of appraisal theories to a nonlaboratory setting and circumventing the shortcomings of previously used methodologies. Also, evidence was obtained that happiness was reported primarily in association with a specific combination of 3 relevant appraisals: high pleasantness, high perceived control, and low moral violation.
