父母支持与服刑青少年的情绪适应:公正世界信念的中介作用

以446名服刑青少年为被试,采用问卷法,探讨了青少年服刑后的父母支持、公正世界信念与其情绪适应的关系及作用机制。结果表明:(1)服刑青少年的情绪适应状况较差,抑郁水平较高,生活满意度较低;(2)服刑后的父母支持和公正世界信念显著负向地预测青少年的抑郁,显著正向地预测其生活满意度;(3)公正世界信念在父母支持和抑郁、生活满意度之间均起着部分中介作用。这表明,服刑后青少年的父母支持既可以直接促进其服刑期间的情绪适应,又可以通过提升其公正世界信念来促进其服刑期间的情绪适应。     

自上而下的注意控制定势在注意捕获中的作用

采用经典前线索范式的变式, 通过100%有效的提示考察了自上而下的注意控制定势在注意捕获中的作用。实验1要求被试在整个实验中只搜索一个固定颜色的目标, 但是通过在每个试次前对目标进行提示加强注意控制定势的强度。实验2通过在每个试次中变化要搜索的目标颜色使被试必须建立两个更强的注意控制定势。实验结果一致表明和目标颜色相匹配的线索捕获了注意, 而和目标颜色无关的线索被抑制; 实验2的捕获效应和抑制效应都显著大于实验1; 对无关冲突线索和无关中性线索的注意抑制效应没有差异, 抑制效应显著小于捕获效应。研究表明自上而下的注意控制定势通过把注意从和目标不匹配的特征位置转移发挥作用, 支持注意转移假说; 对匹配线索的捕获和对无关线索的抑制运用了同一加工系统, 抑制作为捕获的附加产品出现, 两者都可以作为注意捕获的指标。     

医师多点执业制度实施的现状调查及相关建议——以成都市为例

我国于2009年新医改方案提出实施“医师多点执业”制度, 但有关数据显示, 该制度在推进过程中效果并不理想, 为了探究医师多点执业制度的实施现状及其影响因素, 通过问卷调查和访谈对成都市医疗机构人员进行调研。最后在分析调研结果的基础上提出相关建议:采取措施取得医院管理者支持、平衡各方利益冲突、借鉴“团队多地点执业”模式降低医疗风险、加强政策的宣传、建立完善的基层服务体系等, 期望对成都市乃至我国该方案的实施推进提供参考依据。     

Stability of the Positive Mood Effect on Creativity When Task Switching,Practice Effect,and Test Item Differences are Taken into Consideration

Although experimentally induced positive mood can generally last for 20 min and the induced mood is conducive to creative performance, it is still unclear whether the facilitation effect is stable during these 20 min. Two studies were conducted to examine this issue while controlling for the impacts of task switching, practice effect, and test item differences. In Study 1, participants (N = 42) were randomly assigned to positive, negative, and neutral mood conditions. After watching a short video clip, participants answered four items of the Alternate Uses Test (AUT) in 20 min, with 5 min allotted for each item. Creative performance during each 5‐min period was scored in terms of fluency and flexibility. Separate repeated‐measures analyses of variances on these creativity scores showed that positive mood consistently enhanced performance over 20 min. Study 2 further eliminated the effects of test item differences and test order. Participants (N = 131) underwent the same mood induction procedure and answered the same four items of the AUT, except that these items were presented in four different sequences in accordance with the Latin square design. Consistent with the findings in Study 1, Study 2 showed that the facilitation effect of positive mood lasted for 20 min when the interference of task switching, practice effect, and test item differences were minimized. This finding not only sheds light on the debate regarding the stability of experimentally induced positive mood effect, but also contributes to the body of empirical evidence that future studies may use to examine the positive mood effect over a relatively long period of time.     

Does a Nation's Religious Composition Affect Generalized Trust? The Role of Religious Heterogeneity and the Percent Religious

Is religion more of an integrative or a divisive force in contemporary societies? We use multilevel analyses of World Values Survey data from 77,409 individuals in 69 countries to examine how both the percent of the population that is religious and the religious heterogeneity of a country are related to generalized social trust, the willingness of individuals to trust “most people.” When we first examine the main effects of the percent religious and religious heterogeneity we find no evidence that either variable is related to trust in the ways predicted by major theories. However, the combination of these two variables has a huge negative relationship with trust. Countries that are both highly religious and religiously heterogeneous (diverse) have, on average, levels of trust that are only half the average levels of countries with other combinations of these two variables. The results have important implications for understanding the role of religion in modern societies.     

西方哲学心智转向对心理学的影响

心智哲学是20世纪中末期西方哲学所发生的继语言(义)学转向和语用学转向之后的一次重要转向,它为心理学提供了新的元理论和方法论。(1)为心理学提供了"心智-语言-世界"新的世界观;(2)从哲学角度对人的心理进行了探讨,促进了哲学与心理学的结合并互哺;(3)促使人们对"人是什么"重新审视与理解;(4)引发了对以往心理学尤其是主流心理学的基石——身心二元论的质疑;(5)催生了第二代认知科学、活动主义、情境认知等新取向的兴起。它对心理学有很大启示:第一,人工智能、动物研究等研究是有限度的;第二,应重视身体的作用;第三,应重视人的意向性,注重隐喻分析;第四,应关注人的存在,尤其是生命的意义。     

性自由及其限度

性的自由和解放是人的自由解放的重要组成部分,性自由权利是人权的一部分.但是性自由的权利不是无条件的、随心所欲的,而是一定社会规则限定下的人们的自觉自主活动.性自由必须在法律的界限内实现,且必须承担由此而带来的道德责任.     

生存论向度的技术伦理前提及其建构

技术伦理涉及价值观基础、道德规范、技术主体的责任等诸多问题.无论是传统的元伦理学、情感主义伦理学、规范伦理学还是所谓的实用伦理学,都只是从某一个维度上或在某一个层面上来阐述伦理问题,从而在一定程度上表现为对于人的生存价值的背离和对发展合理性的伦理诉求的缺失,这样就使技术伦理研究本身在某种程度上失去了应有的合理性.在合理性上,技术伦理研究不能脱离开对技术本质属性的认识和基本的理论前提.从生存论的向度审视,生存价值才是伦理的内在价值基础,而发展的合理性才是技术伦理建构的基本逻辑支点.只有在此基础上,技术伦理才能实现合理的建构.

Enriched environment treatment restores impaired hippocampal synaptic plasticity and cognitive deficits induced by prenatal chronic stress

Prenatal stress can cause long-term effects on cognitive functions in offspring. Hippocampal synaptic plasticity, believed to be the mechanism underlying certain types of learning and memory, and known to be sensitive to behavioral stress, can be changed by prenatal stress. Whether enriched environment treatment (EE) in early postnatal periods can cause a recovery from these deficits is unknown. Experimental animals were Wistar rats. Prenatal stress was evoked by 10 foot shocks (0.8 mA for 1s, 2-3 min apart) in 30 min per day at gestational day 13-19. After weaning at postnatal day 22, experimental offspring were given the enriched environment treatment through all experiments until tested (older than 52 days age). Electrophysiological and Morris water maze testing was performed at 8 weeks of age. The results showed that prenatal stress impaired long-term potentiation (LTP) but facilitated long-term depression (LTD) in the hippocampal CA1 region in the slices. Furthermore, prenatal stress exacerbated the effects of acute stress on hippocampal LTP and LTD, and also impaired spatial learning and memory in the Morris water maze. However, all these deficits induced by prenatal stress were recovered by enriched environment treatment. This work observes a phenomenon that may contribute to the understanding of clinically important interactions among cognitive deficit, prenatal stress and enriched environment treatment. Enriched environment treatment on early postnatal periods may be one potentially important target for therapeutic interventions in preventing the prenatal stress-induced cognitive disorders.
