妊娠期肝内胆汁淤积症研究中的因果论

妊娠期肝内胆汁淤积症是一种常见的妊娠晚期并发症,对围产儿的危害极大,其确切的病因及发病机制尚未十分清楚。只有了解了疾病的起因,才能更好地进行防治。凡病必有其因,以果推因,再取因治果,这是典型的因果论的应用。     

与年龄及认知功能相关的成人脑波功率涨落图特点

对１２０名２０－７９岁正常受试者完成了与年龄及认知功能相关的脑涨落图特点的研究。结果表明：（１）脑波优势涨落功率空间构型额低枕高梯度的随龄减小过程,在认知测验差组较好组明显;（２）脑波优势涨落功率受年龄与认知因素的交互影响集中于左前右后脑轴上;（３）脑波优势涨落功率前后梯度和左右不对称性变化表明,脑波活动的前后和左右调控可能在不同层次上发挥作用,并且,前后脑和左右脑的协调活动与认知功能有密切关系。上述结果说明,脑波功率涨落与认知功能及其老化过程有密切关系。     

中学生感恩与主观幸福感的关系:抗挫折能力与社会支持的中介作用

采用感恩问卷、正性情感负性情感量表、生活满意度问卷、抗挫折能力问卷和社会支持评定量表对865名中学生进行调查, 以考察中学生感恩和主观幸福感的关系, 以及社会支持与抗挫折能力在两者之间的中介作用。结果:(1)中学生正性情绪显著高于负性情绪;(2)中学生感恩与主观幸福感、社会支持、抗挫折能力相关显著;(3)结构方程分析结果显示, 中学生感恩直接负向预测负性情绪;社会支持和抗挫折能力在感恩与生活满意度、正性情绪间起到完全中介作用, 抗挫折能力在感恩和负性情绪间起部分中介作用。 结论:感恩能通过作用于社会支持和抗挫折能力来影响主观幸福感。     

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。     

群际接触对外群体信任的影响:内群体认同的中介效应

目的:探讨内群体认同在群际接触对外群体信任的中介效应。方法:采用内群体认同量表、群际接触量表和外群体信任量表,对570名大学生进行测量,运用SPSS13.0、Amos22.0对数据进行统计分析。结果:内群体认同作为中介变量,群体接触通过内群体认同对外群体信任的具有稳定的间接作用。     

不同自我和谐水平青少年的认知加工偏向

为了探究不同自我和谐水平青少年的认知加工特点,44名被试先后进行自我相关词语的点-探测任务和词语的再认任务,结果发现:(1)高自我和谐水平的青少年对自我相关的积极词表现出注意优先,低自我和谐水平的青少年对自我相关的消极词表现出注意优先,但两者注意偏向无显著差异;(2)高自我和谐水平的青少年对自我相关的积极词的再认反应时显著短于低自我和谐水平青少年的,对积极词表现出了记忆偏向;低自我和谐水平的青少年对自我相关的消极词、中性词的再认反应时显著短于对积极词的反应时,对消极词、中性词表现出了记忆偏向。因此,不同自我和谐水平的青少年在认知加工的记忆阶段存在特质一致性。     

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.
