策略型学习者认知心理结构及其运行机制

高效率学习是现代社会发展的需要,也是适应信息量急增的社会变革需要的必然选择。从教育心理学的视角研究策略型学习者,对其高效率学习心理,特别是高效率学习认知心理结构及其运行机制进行研究,有助于教育理论与实践工作者准确把握这类特殊教育对象的心理特点与规律,为开展策略型学习者教育提供了心理学依据。     

小学生数学应用题解题水平影响因素的研究——视空间能力、认知方式及表征方式的影响

研究采用3(年级)×2(场认知方式)×2(视空间能力水平)×3(问题表征方式)四因素混合实验设计,探讨了这四种因素对小学生数学应用题解题水平的影响。结果表明:年级、认知方式、空间能力以及问题表征方式均是影响小学生应用题解决水平的关键因素;问题表征方式、认知方式、空间能力以及年级四个因素对小学生解题水平存在交互作用,其中图形提示有利于场依存性学生解题水平的提高,低空间-场依存型的学生更适合图形提示;高空间-场依存型的学生随年级升高解题能力发展较快,而低空间-场依存型的学生解题水平提高较慢;随着年级的升高,图式表征对小学生问题解决的促进作用增强。     

主动建构学习策略和自信的实验研究

目的:通过开设心理健康教育课,促进学生学习策略和自信心的形成。方法:采用问卷法和实验干预法对某中学初一学生进行为期八周的实验干预。结果:实验组学生在学习策略、自信方面的提高水平高于对照组学生,在自信方面,两组学生之间存在明显差异。结论:正确的学习策略和自信心可以主动建构。     

高效率学习的心理机制研究

本课题通过一系列研究,发现要实现高效率学习,应在知识呈现符合学生认识规律的情况下,具备以下五个主要心理要素:选择性注意是实现高效率学习的前提,元认知是高效率学习的监控系统,非智力因素是高效率学习的动力源泉,学习策略是实现高效率学习的保障,内隐认知,特别是内隐学习是高效率学习的特殊形式。     

The Role of Strategy in Mixed-Gender Group Interactions: A Study of the Television Show “The Weakest Link”

This paper studies mixed-gender group interactions in a strategic game where group members are sequentially eliminated till a single winner takes all. Study 1 tests the hypothesis that female contestants are retained till final rounds where they are eliminated. Using observational data from the US television show The Weakest Link (20 shows), results show that females are finalists but not winners. In a laboratory study (Study 2, 67 Berkeley undergraduates), we show that this effect is attenuated when winnings are shared among finalists (versus one winner takes all) due to the reduction in competitive pressures in the context. This research was supported in part by the Junior Faculty Research Grant awarded by the University of California at Berkeley to the second author.     

从炎症在心力衰竭进展中的作用谈心力衰竭治疗策略的制订

心力衰竭是一个以免疫激活和低程度的慢性炎症为特点的疾病。一些炎症因子能通过促进心肌细胞肥厚、恶化心肌收缩功能以及诱导凋亡,在心衰的发展过程中具有重要作用。炎症因子能成为心衰治疗的重要目标。但炎症因子还有心脏代偿和保护作用。制订新的心衰治疗策略时需要进一步了解心衰中炎症反应激活的机制。     

结核病直接督导短程化疗策略的伦理学视角

从伦理学角度探讨了结核病直接监督下短程化疗(DOTS)策略以及DOTS策略实施过程中若干问题。DOTS策略被认为是当今结核病诊治和管理的最有效方法,体现了医学伦理学的公益论;尊重病人的选择及隐私是有效控制结核的重要内容,标准化疗方案和个体化疗方案应视病情而定;医务人员应有良好的综合素质。     

“To eat or not to be eaten?” Collective risk-monitoring in groups

The importance of risk-monitoring has been increasing in many key aspects of our modern lives. This paper examines how individuals monitor such risks collectively by extending a behavioral ecological model of animal foraging to human groups. Just as animals must forage for food under predatory risk, humans must divide valuable material and psychological resources between foraging activity and risk-monitoring activity. We predicted that game-theoretic aspects of the group situation complicate such a trade-off decision in resource allocation, eventually yielding a mixed equilibrium in a group. When the equilibrium is reached, only a subset of members engage in the risk-monitoring activity while others free-ride, concentrating mainly on their own foraging activity. Laboratory groups engaging in foraging under moderate risk provided a support to this prediction. When the risk-level was set higher, however, “herding behavior” (conforming to the dominant behavior) interfered with the emergence of equilibrium. Implications for risk management are discussed.     

肝豆状核变性（Wilson病）治疗策略的变革及思考

评析肝豆状核变性(WD)当前的治疗方法,主要有低铜饮食,铜的螯合剂青霉胺及曲恩汀,锌制剂和四硫钼酸胺,肝移植。介绍WD治疗策略的变革:不再提倡驱铜疗法以去除堆积的铜,而是使血液中的游离铜离子浓度常态化以逆转铜中毒,并结合2007年《柳叶刀》WD治疗专家共识进行思考。最后,展望未来对WD可能的根治疗法,即基因治疗、肝细胞移植及现在可施行的肝移植。     

颈椎病现代针灸的腧穴谱

访视护理作为卫生事业发展中一个新生事物,具有服务场所的家庭化、服务关系的稳定性、服务内容的广泛性等特点,在疾病预防和康复指导中发挥着重要作用,大力发展访视护理具有极大的现实意义。访视护理的发展有其历史文化背景,应从观念、人才培养和规范管理等方面加强和发展访视护理。
