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。     

β受体阻滞剂治疗慢性心力衰竭作用机制规律的探讨

β受体阻滞剂作为一种负性肌力药物,其在慢性心力衰竭治疗中的地位于近几十年中发生了戏剧性的改变,由禁忌药转变为指南推荐的重要药。β受体阻滞剂引发了人们对慢性心力衰竭发病机制的重新思考,使人们对疾病及其治疗有了更新更全面的认识,这其中体现了哲学与自然科学间的紧密联系,提示我们运用哲学原理可以指导自然科学的发展。     

Oscillatory priming and form complexity

Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display locations subsequently occupied by the target. Five experiments were performed to investigate how priming is affected by both the complexity and the geometry of prime/target forms. Experiment 1 showed that the subjective complexity of different polygons was coded in accord with an objective measure of form complexity. Experiments 2 and 3 revealed oscillatory priming to increase as a function of the subjective complexity of prime/target forms when those forms were regular and predictable. However, Experiments 4 and 5 showed that this relation did not hold when the prime/target forms were irregular and unpredictable. Taken together, it is argued that both subjective complexity and the Pr?gnanz quality of the prime/target forms come to determine the magnitude of priming. These results are discussed with reference to current physiological hypotheses regarding perceptual organization.     

加工水平和呈现时间对错误记忆的影响

在DRM范式下,通过操纵加工水平和呈现时间,考察它们对错误记忆和真实记忆的影响.结果发现,加工水平对错误记忆没有影响,随着对词表加工水平的提高,错误再认率差异不显著.而加工水平对正确记忆有显著影响,不同加工水平间的正确再认率差异极其显著.错误记忆与正确记忆在加工水平上表现出了分离.在较慢呈现时间下,呈现时间对错误记忆和正确记忆的影响均不显著.     

"锚定参照错误"偏向对贝叶斯推理成绩的影响

采用贝叶斯推理问题作为实验材料,通过分析被试推理过程中的理由叙述,探讨被试贝叶斯推理所使用的启发式策略,从认知偏向的角度分析该问题的困难原因.结果发现:(1)在贝叶斯推理过程中,对"击中率"命题的"换位表征"错误和锚定"基础比率"信息导致了"锚定参照错误"偏向,从而表现出对贝叶斯推理成绩显著的高估或低估;(2)"锚定参照错误"偏向程度和锚定参照目标受任务情境的影响;(3)解决良构的问题和非良构的问题时,"换位表征"的现象都有可能发生,而且表现得比较一致.     

工作卷入研究的新趋势

工作卷入的研究处于不断的发展之中.从复杂、泛化的多因素的概念与结构发展到简单、内化的单因素的概念与结构;从理论上关注个体评价过程到重视个体--环境相匹配的观点;从工作场所的卷入研究到非工作场所的卷入度研究;以及从原来的只有在美国的研究扩展到开始关注跨文化的比较研究.最后,文章还对今后研究的热点与方向进行了展望.

Neural correlates of Traditional Chinese Medicine induced advantageous risk-taking decision making

This fMRI study examined the neural correlates of the observed improvement in advantageous risk-taking behavior, as measured by the number of adjusted pumps in the Balloon Analogue Risk Task (BART), following a 60-day course of a Traditional Chinese Medicine (TCM) recipe, specifically designed to regulate impulsiveness in order to modulate risk-taking behavior. The 14 participants recruited for this study were randomly assigned to the experimental and control groups and the TCM recipe (Panax, 520 mg; Astragalus membranaceous Bunge, 520 mg; Masnetitum, 840 mg; Ostrea gigas Thumb, 470 mg; Thinleaf Milkwort Root Radix Polygalae, 450 mg; and Os Draconis, 470 mg) was administered, as a diet supplement, to the seven participants in the experimental group. The neural activity of the two groups was monitored by a 3T MRI scanner, before and after the 60-day treatment. Associated with the improved advantageous risk-taking behavior seen in the experimental group, significantly stronger blood oxygenation level dependent (BOLD) responses were observed in the bilateral dorsolateral prefrontal cortex (DLPFC), left putamen, left thalamus, right insula, and right anterior cingulate cortex (ACC), regions which have previously been reported as being involved in risk-taking decision making. The effect of the TCM in improving advantageous risk-taking decision making appears to have been related to the enhanced efficiency of the cognitive affective system, the PFC–ACC–insula–striatum network, which functions to inhibit impulsiveness, to sensitize reward-related information, and to allow the opportunity, during risk estimation, to evaluate potential gains and losses. The findings of this study suggest that interventions acting on factors modulating risk-taking decision making could have a beneficial effect in terms of optimizing risk-taking behavior.     

吉林、大连举办道教文化活动

我国的东北地区,是道教传播的重要区域之一.战国秦汉之际,东北地区就有方仙道的踪迹.全真道兴起后,很快就传到了东北地区.现已发现一些金末元初的全真道碑刻.人清以后,东北道教中兴.道教在东北民众的生活中打下了深深的烙印,渗透到了民间风俗之中.东北地区的年节时令和日常礼俗与道教文化有着密切的关系.
