Toward using confidence intervals to compare correlations

Confidence intervals are widely accepted as a preferred way to present study results. They encompass significance tests and provide an estimate of the magnitude of the effect. However, comparisons of correlations still rely heavily on significance testing. The persistence of this practice is caused primarily by the lack of simple yet accurate procedures that can maintain coverage at the nominal level in a nonlopsided manner. The purpose of this article is to present a general approach to constructing approximate confidence intervals for differences between (a) 2 independent correlations, (b) 2 overlapping correlations, (c) 2 nonoverlapping correlations, and (d) 2 independent R2s. The distinctive feature of this approach is its acknowledgment of the asymmetry of sampling distributions for single correlations. This approach requires only the availability of confidence limits for the separate correlations and, for correlated correlations, a method for taking into account the dependency between correlations. These closed-form procedures are shown by simulation studies to provide very satisfactory results in small to moderate sample sizes. The proposed approach is illustrated with worked examples.

内隐地域刻板印象的IAT和SEB比较研究

本研究以上海行政区为划分标准,探讨了"上海人"和"非上海人"群体的地域刻板印象以及"内-外群体效应"。结果发现:(1)IAT结果表明,被试在不相容条件下的反应时显著高于相容条件(t(25)=3.282,p<0.01);(2)SEB结果表明,被试对于不符合刻板印象的句子做出解释的次数显著多于符合刻板印象的句子(t(73)=2.844,p<0.01),且不同地域来源的被试做出的内、外归因也有显著差异(t(72)=3.172,p<0.01)。研究采用两种测验方法证实了地域刻板印象的存在,并且通过实践验证了SEB作为内隐社会认知研究方法的有效性。     

武汉地区大学生社会能力的结构及其问卷编制

从分析大学阶段的关键性发展任务出发,将我国大学生的社会能力分为事务处理能力、一般人际交往能力和建立与发展友谊的能力三个方面。以文献研究为基础,结合开放式问卷所获资料,分别提出了关于这三种社会能力结构的理论构想,编制了大学生社会能力问卷。武汉市1048名大学生参与了正式问卷的施测,结果表明,事务处理能力的四因素结构、一般人际交往能力的五因素结构和建立与发展友谊的能力的五因素结构是较为合理的,自编大学生社会能力问卷的信效度达到心理测量学要求。     

应激对中国地鼠糖尿病发生的影响

研究实验性应激、情绪性、笼架水平在中国地鼠糖尿病发生中的作用强度及其交互作用,以确定中国地鼠糖尿病发生危险因素。结果表明实验性应激(震动、旋转合并限制)能促使中国地鼠血糖水平显著升高,糖尿病发病率增加,发病年龄提前;高情绪性中国地鼠,随着实验时间延长,其发病率也逐渐升高,并稳定在一定水平;析因方差分析提示,实验性应激与动物情绪性的交互作用对实验后中国地鼠的血糖变化起主要作用。     

亲亲相隐何时休?关系对揭发意向影响的边界

当组织中做出不道德行为的人跟自己关系非常亲近时,员工可能不会揭发他们的不道德行为,进而给组织带来潜在的隐患。鉴于先前研究较少关注如何降低不道德情境中关系的包庇作用,本研究考察了组织和个体特征在削弱关系与揭发负向关系方面扮演的调节角色。结果表明,关系会抑制员工对不道德行为的揭发意向(研究1~3),且关系对员工揭发意向的负向影响受到了组织关系取向(研究1和3)与员工正直(研究2和3)的调节。随着组织关系取向的下降或员工正直程度的提升,关系对员工揭发意向的抑制作用逐步降低。这些结果对于组织内部揭发机制设计具有借鉴意义。     

Dorsomedial prefrontal cortex 5-HT6 receptors regulate anxiety-like behavior

The dorsomedial prefrontal cortex (dmPFC) plays a very important role in decision-related and anxiety-related information processing. It has enriched 5-HT6 receptors; however, the precise role of dmPFC 5-HT6 receptors in anxiety remains to be fully investigated. In this study, we injected dmPFC with the 5-HT6 receptor agonist EMD 386088 and antagonist SB 271046 using stereotactic technology. 5-HT6 receptor activation in mice increased time spent in the center area on the open-field test, increased exploration of the open arms on the elevated plus maze test, and increased ratio on the social interaction test. 5-HT6 receptor inactivation induced the opposite effects. In brain slices, EMD 386088 decreased both spontaneous inhibitory postsynaptic currents (sIPSC) and spontaneous excitatory postsynaptic currents (sEPSC), while SB 271046 only increased sEPSC. These effects of EMD 386088 and SB 271046 could be reversed by the GABA_A receptor antagonist bicuculline (BMI) and positive allosteric modulator clonazepam (CLZ), respectively. Our results suggest that neurotransmission in the dmPFC by 5-HT6 receptor activation and inhibition may play an important role in anxiety-like behavior, and may provide new insight into the pathological mechanism and potential target of anxiety disorders.     

再论唯物史观与启蒙

唯物史观近年来复又成为学界探讨的重点。其中唯物史观同欧洲思想传统的关系,成为探讨的重要方向。笔者曾发表《唯物史观对启蒙的超越与转化》(见《哲学研究》2008年第6期),对问题作了一些初步探讨。近年来,我们一直在拓展相关研究。①本文结合课题的现当代视域,再作一些探     

马克思主义宗教批判思想之辨析

马克思主义的宗教批判思想,实质上是19世纪以来越来越鲜明的世俗化过程中反叛宗教神学的一种极端形式。不能从唯物主义世界观直接推出信仰层面的无神论,马克思新唯物主义以及唯物史观形成,同时也是对无神论的明确的扬弃。马克思对宗教持激进的批判与否定态度,至于把这样的态度解读为宗教精神的再度复活,其实是引伸开来的思想,同马克思本人的宗教批判思想无关。马克思的宗教批判从宗教产生的经济与政治关系入手展开对宗教及其社会现象的意识形态批判,也是一种宗教社会学。马克思的社会概念以及社会主义,意在通过从哲学到共产主义实践的转变成为无神论时代社会共同体的新的信仰,但涂尔干与韦伯则以不同的的方式证明了现代性社会的信仰及其认同依然是诉诸于宗教理解方式。如何面对现代世界宗教现象的多样性与复杂性,是马克思主义宗教批判思想面临的难题。     

Emotional reactions to scandals: When does moral character make a difference?

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.
