共情的认知神经研究回顾

共情是指个体对他人情绪和想法的感受及理解,它在人类个体和社会的发展中起到了重要作用。近年来,脑成像技术为研究共情的神经基础提供了有力的技术支持,发现了共情的关键功能脑区。基础与临床的实验证据表明,更好地理解共情的神经机制对于孤独症、反社会人格等精神障碍有重要的意义。该文对相关的研究进行了综述并对未来可能的研究方向提出了展望     

贬损型幽默:笑声能化解敌意吗?

贬损型幽默指包含贬损意味同时令人发笑的信息。释放论、优越论、失谐?解决理论与良性进犯理论尝试解释了其心理机制。贬损不一定好笑,群体身份和态度、接收者与贬损对象的心理距离以及人格、文化差异等均会影响幽默效果。贬损型幽默可以起到释放偏见与表达社会支配倾向的作用,对人际交往的作用则不一致。贬损型幽默的整合性过程模型串联描述了贬损型幽默的机制、前因和后效,可作为未来研究的框架。未来亦可继续探讨贬损型幽默的消极影响,以及其对群际关系和社会公平的潜在积极作用,并关注到中国社会文化背景下的贬损型幽默。     

孟子是贤能政治的支持者吗?——从民意观的角度看

基于对现代民主政治的反思,白彤东推荐一种儒家混合政体,这种政体的一大特色就是放弃民主制的“民治”原则,转而采用贤能政治的“能人治国”理念。白彤东宣称,这种“能人治国”理念是他从孟子那里得到的灵感。然而,白彤东对孟子的解读存在着不可忽略的错误。更令人遗憾的是,为了证成自己的观点,他不惜对《孟子》文本采取了有选择的无视。有理由相信,白彤东其实已经意识到他跟孟子之间的巨大差异,这个差异在民意观上体现得尤其明显。     

右侧颞顶联合区及道德加工脑网络的功能连接预测社会性框架效应：来自静息态功能磁共振的证据

社会性框架效应指个体进行社会性决策时, 描述方式(即框架)对其选择倾向的影响。采用“伤害/帮助框架”范式, 本研究在行为上发现了显著的框架效应：被试在伤害框架下比帮助框架下, 更倾向于选择利他选项, 这可能是由于伤害框架凸显了伤害他人的后果及有意性, 从而提高了道德冲突水平。在神经活动上发现(1)静息态下, 右侧颞顶联合区(TPJ)的低频振荡振幅(ALFF)与框架效应强度存在显著正相关; (2)道德加工相关脑区构成的局部脑网络内部的功能连接强度(FC)能够有效预测框架效应强度。本研究首次利用静息态功能连接探讨个体的社会性决策受到语言表述方式影响的神经机制, 为进一步揭示社会决策中的个体差异提供了神经学证据。     

职场排斥对培训行业员工建言行为的影响——有调节的中介作用模型

研究采用问卷法,以安徽、天津的培训机构中的401名在职员工为研究对象,以组织支持感作为中介变量,以积极心理资本作为调节变量,从资源保存理论的视角探讨了职场排斥对员工建言行为的影响。研究结果表明:(1)职场排斥对员工的建言行为具有负向预测作用,职场排斥水平越高,其建言行为水平越低。(2)组织支持感在职场排斥与建言行为之间起中介作用,职场排斥通过组织支持感影响员工的建言行为。(3)组织支持感的中介作用受到积极心理资本的调节,积极心理资本会增强组织支持感的中介作用。     

基于分部评分模型思路的多级评分认知诊断模型开发

基于分部评分模型的思路, 本文提出了一般化的分部评分认知诊断模型(General Partial Credit Diagnostic Model, GPCDM), 与国际上已有的基于分部评分模型思路的多级评分模型GDM (von Davier, 2008)和PC-DINA (de la Torre, 2012)相比, GPCDM的Q矩阵定义更加灵活, 项目参数的约束条件更少。Monte Carlo实验研究表明, GPCDM模型的参数估计精度指标RMSE介于[0.015, 0.043], 表明估计精度尚可; TIMSS (2007)实证数据应用研究表明, 与GDM和PC-DINA模型相比, GPCDM与该数据的拟合度更好, 并且使用GPCDM分析该数据的诊断效果也更优。总之, 本研究提供了一种约束条件更少、功能更为强大的多级评分认知诊断模型。     

小学儿童对日常生活事件时间关系推理能力的初探

探查小学儿童对含有“在什么之前”“同时”日常生活事件时间关系的推理发展过程及其影响因素。被试为7岁、9岁、11岁3个年龄组共54名小学儿童,每个年龄组18人。4种问题模式分别为带有传递关系的单模型问题、带有无关前提的单模型问题、含两个前提的单模型问题、有肯定答案的多模型问题。每种问题模式含3种具体探察任务。主要研究结果表明：在本实验条件下,（1）儿童对事件时间顺序关系的推理从7岁到9岁有快速发展的趋势;（2）单模型和多模型任务无显著差异,模型数量似乎不是影响儿童推理成绩的关键因素;（3）儿童能够主动采用5种策略解决问题。逆向关系传递策略是问题解决的有效策略。     

Effects of antecedent order and semantic context on Chinese pronoun resolution

Three reading time experiments were conducted in order to examine the relative contributions of order of antecedents and semantic context to the resolution of temporarily ambiguous Chinese pronouns. These pronouns were ambiguous because each of them was preceded by two antecedents, both of which were likely candidates for coreference. The identity of the pronoun was revealed by subsequent disambiguating information that constrained the pronoun to one particular interpretation. Experiment 1 showed that reading of the disambiguating phrase was slower when the phrase confined the pronoun to the second rather than to the first antecedent. Experiment 2 produced the same effect of antecedent order (first vs. second antecedent) regardless of whether the target antecedent was an action-performing or an action-receiving entity. In Experiment 3, the order effect was eliminated by a biasing modifier inserted immediately before the pronoun. These results indicate that in a semantically neutral environment, the first-appearing antecedent is the preferred candidate for coreferencing the ambiguous Chinese pronoun. The interaction between order of antecedents and semantic context (in the form of preposed biasing modifiers) suggests that the initial comprehension of Chinese pronouns depends as much on contextual as on structural factors.     

Characteristics of suicide attempters and nonattempters with schizophrenia in a rural community

In this study, demographic and clinical characteristics of individuals with schizophrenia in a Chinese rural community who had attempted suicide at some time in their lives and those who had not made a suicide attempt were compared. Among individuals with schizophrenia, subjects with (n = 38) and without (n = 472) a lifetime history of suicide attempt were assessed with the Present State Examination. The results indicate that attempters had a significantly younger age, higher level of education, higher rate of lifetime depressed mood and hopelessness, and a larger number of positive symptoms than patients without suicide attempts. The logistic regression models also indicated that hopelessness, the number of positive symptoms and age were the most important predictors. Early interventions focusing on reducing hopelessness and controlling positive symptoms may help reduce the risk of suicide attempts among patients with schizophrenia.     

Perceptions of ADHD in China and the United States: a preliminary study

College students (n = 226) and teachers (n = 328) in the United States and China completed a 55-item questionnaire examining perceptions of attention deficit/hyperactivity disorder (ADHD) in the two countries. Although a factor analysis yielded somewhat similar structures for the construct of ADHD, many differences emerged as well, with Chinese participants somewhat more attuned to hyperactivity than inattention. Furthermore, presented with a list of potential perceptions of ADHD, there were significant differences by culture in agreement with most of those statements. Thus, it appears that the concept of ADHD may be similar between the cultures, but the many differences warrant further exploration before ADHD is considered to be equivalent in the two countries.
