正念冥想对情绪的调节作用:理论与神经机制

正念冥想可调节个体的负性情绪、促进个体正性情绪,对于心身疾病具有显著的干预效用.正念冥想的再感知模型、正念应对模型、推动性上升螺旋模型以及正念情绪调节模型都强调了正念冥想对情绪的调节作用.认知神经科学的研究发现,正念冥想可促进左侧前额叶脑区激活增强,涉及的脑区主要包括背外侧前额叶皮层(DLPFC)和背内侧前额叶皮层(DMPFC).研究者进一步发现,正念特质是通过改善前额叶对边缘系统反应的调节来实现对情绪的调节作用.而且,这种调节作用还有可能体现为通过冥想训练分离联结在一起的两种自我参照神经机制,从而加强体验性神经机制.另外,研究者还发现,正念冥想训练还可以改变与情绪加工相关的大脑结构.进一步澄清冥想训练与大脑偏侧化的关系和不同类型被试之间的比较研究将成为该领域日后研究的重点.     

组织公民行为研究的新视角

对2000年以后组织公民行为领域出现的最新研究动态进行讨论和分析,主要包括基于社会资本和社会网络的组织公民行为研究、社会规范对组织公民行为的影响、群体层次的组织公民行为研究以及对组织公民行为的负面作用的探讨。作者分别讨论了上述4个最近研究方向在我国研究的理论和实践意义,并提出了一些具体的研究建议。最后,作者对这4个研究方向的相互关系和整合提出了自己的观点     

校园氛围与青少年的自杀意念/企图：自尊的中介作用

尽管相当一部分青少年自杀发生于学校背景中,但目前较少有研究考察校园氛围是否会影响以及怎样影响青少年的自杀意念/企图。本研究旨在检验校园氛围的不同方面(教师支持、同学支持、自主机会)与青少年自杀意念/企图的关系,以及自尊在其中的中介作用。采用分层整群抽样的方法,选取广东省10所学校2758名初中生作为被试,匿名填写家庭功能问卷、社区问题问卷、校园氛围问卷、Rosenberg自尊量表、自杀意念与企图问卷。回归分析表明:(1)在控制了性别、年龄、社会经济地位、家庭功能和社区问题后,教师支持和同学支持均能显著负向预测自杀意念/企图,自主机会对自杀意念/企图的预测作用不显著;(2)自尊在教师支持和同学支持与自杀意念/企图之间起着中介作用。因此,实践工作中应重视教师支持和同学支持对青少年自尊的塑造作用,进而减少自杀意念/企图。     

常规会阴切开与过度医疗

本文总结了国内外阴道分娩过程中会阴切开率的变迁.受社会、医方及产妇等因素影响,我国会阴切开已逐渐成为产时常规手术,大量不必要的会阴切开以及手术造成的伤害,就形成了过度医疗,即预防性手术过度使用.围绕社会、医方及产妇因素三个方面,笔者提出了相应降低会阴切开率的对策,特别强调产科医务人员的人文素养、专科理论与技能和医院管理在控制会阴切开过程中的作用.     

Mood,Anxiety, and Substance‐Use Disorders and Suicide Risk in a Military Population Cohort

There are meager prospective data from nonclinical samples on the link between anxiety disorders and suicide or the extent to which the association varies over time. We examined these issues in a cohort of 309,861 U.S. Air Force service members, with 227 suicides over follow‐up. Mental disorder diagnoses including anxiety, mood, and substance‐use disorders (SUD) were based on treatment encounters. Risk for suicide associated with anxiety disorders were lower compared with mood disorders and similar to SUD. Moreover, the associations between mood and anxiety disorders with suicide were greatest within a year of treatment presentation.     

线上社交焦虑:社交媒体中的人际负性体验

线上社交焦虑指个体在社交媒体交往情境中感知到的紧张和恐惧等人际负性体验,包含隐私担忧、交往焦虑和负面评价恐惧三个方面。线上社交焦虑可以通过质性分析法、实验诱发法和问卷测量法进行研究。线上社交焦虑既会受到社交媒体自身特点、个体特征因素、网络欺凌和文化因素的影响,还会对个体的心理与行为产生后效。未来研究者需要开发有效的本土化测量工具、探索其形成和作用机制、关注线上社交焦虑悖论以及推动对其干预。     

Bayesian evaluation of informative hypotheses for multiple populations

The software package Bain can be used for the evaluation of informative hypotheses with respect to the parameters of a wide range of statistical models. For pairs of hypotheses the support in the data is quantified using the approximate adjusted fractional Bayes factor (BF). Currently, the data have to come from one population or have to consist of samples of equal size obtained from multiple populations. If samples of unequal size are obtained from multiple populations, the BF can be shown to be inconsistent. This paper examines how the approach implemented in Bain can be generalized such that multiple-population data can properly be processed. The resulting multiple-population approximate adjusted fractional Bayes factor is implemented in the R package Bain.     

Difficult name,cold man: Chinese names,gender stereotypicality and trustworthiness

Names can play an important role in forming first impressions. While much of the literature has demonstrated how alphabet-based names influence impression formation, little is known about how character-based names (e.g., Chinese names) affect interpersonal trust. Across six studies, we demonstrated that a difficult-to-recognise Chinese name with less frequently used characters activated masculine perception, which in turn decreased trust in the name holder. The masculine inferences from difficult names were replicated across within-subjects (Study 1a and 1b) and between-subjects judgements and maintained irrespective of normative knowledge about difficult names as male names (Study 1c). The mediation of gender stereotypicality was manifested in both measured spontaneous gender inference (Study 2a and Study 2b) and manipulated gender information (Study 2c). The effects of recognisability on masculine and trust perceptions were independent of pronunciationability (Study 2b). This research extends previous research by revealing the implications of character-based names and pictographic language on the feeling-as-information theory, also in terms of interpersonal contexts.
