Effects of incidental positive emotion and cognitive reappraisal on affective responses to negative stimuli

Previous studies have identified two powerful ways to regulate emotional responses to a stressor: experiencing incidental positive emotions and using cognitive reappraisal to reframe the stressor. Several cognitive and motivational theories of positive emotion support the formulation that incidental positive emotions may facilitate cognitive reappraisal. To test the separate and interacting effects of positive emotions and cognitive reappraisal, we first adapted an established picture-based reappraisal paradigm by interspersing blocks of positive emotion inducing and neutral pictures. Across two pre-registered studies (Studies 1, 2), reappraisal effectively decreased self-reported negative emotions and increased self-reported positive emotions; however, experiencing incidental positive emotions did not facilitate reappraisal success. In another preregistered study (Study 3), we employed a more powerful positive emotion induction via virtual reality (VR), used a social stress anticipation task, and instructed participants to reappraise the anticipated stressor positively. Although there was a robust effect of the positive emotion induction (relative to the neutral induction) on feeling more positive emotions throughout stress anticipation, the results again indicated that incidental positive emotions did not facilitate cognitive reappraisal. We propose that incidental positive emotions and cognitive reappraisal may constitute separate pathways of influence when regulating one's responses to negative events.     

右腹外侧前额叶对高抑郁水平成年人社会情绪调节的作用：一项tDCS研究

已有的经颅直流电刺激(transcranial direct current stimulation, tDCS)研究证明, 右腹外侧前额叶(right ventrolateral prefrontal cortex, RVLPFC)是社会情绪调节的重要脑区, 激活RVLPFC可显著降低人们对社会性负性情绪体验的强度。社会功能受损是抑郁症患者或抑郁倾向人群的重要特征之一。该群体对社会排斥的敏感性高, 且对负性社会情绪体验的情绪调节能力降低。在本研究中, 我们采用外显的情绪调节任务, 研究了高、低抑郁水平的两组成年人被试在RVLPFC接受阳性tDCS后其情绪调节能力的改变。结果表明, 虽然采用tDCS激活RVLPFC可帮助被试通过情绪调节(认知重评)减弱负性情绪体验, 但高抑郁水平被试的负性情绪强度下降程度明显小于低抑郁水平被试。另外本文还发现, 与源于个人的负性情绪相比, tDCS效应对源于社会的负性情绪(即社会排斥)更强。本研究是采用电或磁刺激提高抑郁人群社会情绪调节能力的首次尝试。实验结果表明, 高抑郁水平成年人的RVLPFC仅通过单次、短时间(34 min)的tDCS激活, 其情绪调节能力并未得到显著提升。这提示对抑郁倾向群体或抑郁症患者的干预或治疗需要多次施加tDCS。     

工作压力对建设型和防御型建言的差异影响

以往研究普遍从建言行为的建设性意图特征出发, 探讨其关键前因、产生机制和情境因素, 但却较少关注建言行为的工具性目的。基于资源保存理论, 本研究构建了有调节的中介模型以探讨工作压力影响员工建设型建言和防御型建言的作用机制和边界条件。通过对某建筑企业386名员工进行两阶段调查, 结果表明：工作压力与防御型建言存在正向相关关系, 与建设型建言存在负向相关关系, 自我损耗在其中起中介作用; 另外, 领导开明性正向调节自我损耗和建设型建言的负向相关关系, 并正向调节工作压力通过自我损耗影响建设型建言的间接效应。     

发展性阅读障碍儿童的新词习得及其改善

本研究通过比较重复学习新词时个体眼动模式的变化, 探讨发展性阅读障碍儿童的新词习得及改善途径。实验1以发展性阅读障碍、生理年龄和阅读能力匹配儿童为被试, 采用重复学习新词的范式, 探讨发展性阅读障碍儿童的新词习得。结果发现, 与匹配组相比, 发展性阅读障碍儿童在新词的首次注视时间和凝视时间上需要更多的语境才出现显著下降, 且在总注视时间上表现出更缓慢的下降。表明发展性阅读障碍儿童的新词习得慢于正常儿童。实验2以词间空格和正常无空格两种文本呈现方式, 仍采用重复学习新词范式, 探讨词间空格是否能促进发展性阅读障碍儿童的新词习得。结果发现, 在词间空格条件下, 发展性阅读障碍儿童的新词习得可达到正常儿童的水平。表明作为视觉词切分线索的词间空格, 可促进发展性阅读障碍儿童的新词习得。本研究结果为发展性阅读障碍儿童新词习得提供了一条新的途径。     

Measuring decision‐making competence in Chinese adults

In this study, we translated and localized the Adult Decision‐making Competence scale (A‐DMC) and tested its reliability and validity with large samples. Results show the Chinese A‐DMC has relatively good reliability (Cronbach's alpha above 0.6 and test–retest reliability coefficients ranging from 0.44 to 0.78 on all subscales), comparable with the original version. Regarding validity, results of exploratory factor analysis and confirmatory factor analysis support the one‐factor model, indicating the A‐DMC has good internal consistency and construct validity. A‐DMC scores correlated positively with cognitive ability, constructive decision‐making styles, and good decision outcomes. Additionally, individuals with higher A‐DMC scores were found to perform better on the Cambridge gambling task and Iowa gambling task. These results confirm the validity of the Chinese version of the A‐DMC, which is suitable for measuring decision‐making competence in Chinese adults.

Infant sustained attention but not joint attention to objects at 9 months predicts vocabulary at 12 and 15 months

Vocabulary differences early in development are highly predictive of later language learning as well as achievement in school. Early word learning emerges in the context of tightly coupled social interactions between the early learner and a mature partner. In the present study, we develop and apply a novel paradigm—dual head‐mounted eye tracking—to record momentary gaze data from both parents and infants during free‐flowing toy‐play contexts. With fine‐grained sequential patterns extracted from continuous gaze streams, we objectively measure both joint attention and sustained attention as parents and 9‐month‐old infants played with objects and as parents named objects during play. We show that both joint attention and infant sustained attention predicted vocabulary sizes at 12 and 15 months, but infant sustained attention in the context of joint attention, not joint attention itself, is the stronger unique predictor of later vocabulary size. Joint attention may predict word learning because joint attention supports infant attention to the named object.     

社会困境中合作行为的阶层差异：自我与他人的双重视角

为了探究个体自身与他人的社会阶层对个体在社会困境中合作行为的影响及其作用机制,本研究通过问卷和实验研究来考察自身阶层的行为效应、互动对象阶层的调节效应以及信任有中介的调节作用。研究发现：（1）低阶层者倾向于比高阶层者表现出更多的合作行为;（2）感知到的互动对象阶层对不同阶层个体的合作行为存在显著的调节效应;（3）个体对互动对象的信任水平（即对他人合作行为的预期）对此调节效应起到中介作用。     

时间焦点对前后方向上内隐时空映射的影响——来自汉族和羌族的证据

采用不同的研究方法考察汉族和羌族被试内隐时空映射的联结方向及其影响因素。实验1利用时间图表任务发现, 汉族被试对“过去在前”和“未来在前”两种内隐时空映射没有表现出明显偏好, 而羌族被试更加倾向于使用“过去在前”的内隐时空映射。由于二者均使用汉语, 但其内隐时空映射却存在差异, 显示出时间语言和时间思维的分离性。实验2利用时间焦点量表考察汉族和羌族被试对过去和未来时间的关注程度。结果发现, 前者对过去和未来的注意力程度相当, 而后者表现出较强的“过去朝向思维”, 说明文化中的时间焦点偏好可以较好地预测二者的内隐时空映射。实验3利用时间概念分类任务发现, 内隐时空映射有利于促进汉族和羌族被试时间概念的表征和加工, 出现了“隐喻一致性效应”。整个研究表明, 汉族和羌族文化中个体对待时间的态度可以决定其内隐时空映射联结方向, 支持“时间焦点假设”。     

哲学对劳动价值理论研究的关注--兼与张华夏教授的价值主客观二重性的讨论

本文在张华夏教授关于一般价值概念的基础上,提出了价值概念不仅要重视价值客体属性的状态特征,也要关注它的过程特征,从而发展了一般价值概念的结构。经济学中,四种经济价值理论分布在一般价值概念结构的不同位置上,劳动价值理论处于核心位置。是硬核。传统经济理论的危机和人力资本理论的兴起,说明理论界对劳动价值理论这个硬核的研究还是很不够的,同时从我国理论界当前的研究成果来看,马克思的劳动价值理论还有进一步发展的巨大潜力。
