Mechanisms for attentional modulation by threatening emotions of fear,anger, and disgust

Appropriately attending to threatening environmental stimuli is evolutionarily adaptive and crucial for survival. This study revealed that nonconscious attentional modulation of disgust has different behavioral and event-related potential (ERP) patterns, as compared to fear and anger. To facilitate its evolutionary purpose of avoidance, disgust first diverts rather than attracts attention. Accordingly, the N1 was smaller in a validly than in an invalidly disgust-cued condition. Furthermore, the frontal P3a for disgust, anger, and fear was found to be larger in the valid than in the invalid condition, which was interpreted as an involuntary switching of attention toward threat-related events to mobilize cognitive resources for action or defense. On the contrary, the parietal P3b only occurred at the conscious level; the enhanced P3b indicated that more cognitive resources were being allocated toward the task-relevant but previously less attended location, to ensure the effective achievement of task goals. In addition, group comparisons between individuals with low and high disgust sensitivity showed that the ERP differences between the disgust and the anger/fear conditions at the unconscious level may be attributed only to individuals with high disgust sensitivity. These findings, together with previous knowledge of the effects of fear and anger on attention, strengthen our confidence in the two-stage scheme of attentional modulation by threats, which consists of an early stage of bottom-up response scaling of sensory processing (reflected by the P1 and N1) and a later stage of top-down integration and regulation of emotion and behavior (reflected by the P3).     

谦卑型和自恋型领导:跨文化组织管理的视角

谦卑型领导和自恋型领导的概念差异体现在在自我认识、对待他人态度、动机、情绪、行为方式等方面。并且,谦卑型领导和自恋型领导在管理员工、团队、组织方面分别存在优势和劣势,谦卑型领导和自恋型领导之间存在相互独立且共存的关系。基于跨文化管理的视角,研究显示谦卑型领导和自恋型领导存在潜在的文化差异,且具有不同的形成基础,并在内隐领导理论上存在差异,最后,二者均是文化适应性的结果。未来研究可关注谦卑型领导和自恋型领导内涵的文化特异性、前因变量、研究方法、文化动态建构和文化认同强度等问题。     

积极情绪体验对创造力影响

通过行为数据、生理数据和主观报告"三位一体"的方法,随机抽取60名大学生为被试,采用单因素3水平(情绪体验类型:感动、愉快、中性)被试间设计,以科学发明创造实验问题为创造力测试材料,探讨了不同类型的积极情绪体验对创造力的影响。结果发现:积极情绪体验能有效促进创造力的发挥,但是不同的积极情绪体验类型效果不同。与中性情绪体验相比,感动体验和愉快体验对创造力都具有显著促进作用,且感动体验效果更好。不同积极情绪体验下男女被试在创造力上并无差异,这表明创造力水平并不存在男女性别差异。     

父母早期受虐与子女对立违抗症状的关系:亲子虐待和儿童愤怒管理的作用

本研究探讨了父母的早期受虐经历与子女的对立违抗症状的关系,通过构建一个有调节的中介模型,考察了亲子虐待的中介效应和儿童愤怒管理对该效应的调节作用。采用问卷法对359名来自北京市、山东省和云南省的14所小学一至五年级的儿童及其父母进行调查,研究工具包括儿童对立违抗症状评估表、童年期创伤问卷、儿童愤怒管理量表。结果发现：（1）男孩的ODD症状得分显著高于女孩;男孩受到的躯体虐待、情感忽视和躯体忽视显著多于女孩（2）在控制了儿童性别后,父母在童年期的受虐经历仍可显著正向预测其成年期的家庭中子女的ODD症状;（3）亲子虐待在父母受虐和子女ODD症状之间起完全中介作用,即父母受虐通过亲子虐待间接影响子女ODD症状;（4）父母受虐通过亲子虐待影响子女ODD症状的中介效应后半路径受到子女个体水平愤怒失调（AD）的调节,具体来说,当AD水平较高时,亲子虐待对ODD症状的影响更大;但愤怒应对（AC）和愤怒抑制（AI）对中介效应无显著调节作用。     

感激情绪的认知评估体系

本文从情绪认知理论的角度出发, 通过3个研究探究与感激情绪有关的认知评价维度, 进而建立感激情绪的认知评价体系。研究1使用回忆不同类型的情绪性事件法初步探究了感激情绪的认知评估体系; 研究2使用操作认知评估维度法探究了认知评价的变化对感激体验的影响; 研究3使用故事情境法分别从个体特质和情境因素的角度, 探究个体特质与感激情绪之间的关系如何受到个体认知评价的影响, 进而为感激情绪的评价体系提供更多的证据支持。研究1发现感激情绪体验与受关怀感、符合道德规范和他人负责性3个维度之间存在正相关关系。研究2发现3个认知评估维度体验的有无均会导致个体在感激情绪体验上出现显著差异。研究3表明感激特质可以预测个体的认知评价和感激情绪体验; 同时, 受关怀感、道德规范、他人负责3个认知评价维度在感激特质与感激情绪关系间起到中介作用。结论：3个研究结果表明, 受关怀感、道德规范、他人负责性3个认知评价维度与感激密切相关, 并在区分开感激与自豪、亏欠感等情绪中起重要作用。因此, 这3个认识评估维度共同组成了感激情绪认知评价体系。     

发展性计算障碍的最新研究进展

发展性计算障碍是一种影响算术技能获得的特定的学习障碍。截至目前,有关发展性计算障碍的认知与神经机制的理论尚存分歧,有关诊断与鉴别标准也未统一。近年来,对于发展性计算障碍的理论假设有从一般认知因素取向到数学特定因素取向发展的趋势。而随着脑成像技术的不断发展,对于发展性计算障碍神经机制的研究也从针对单个脑区的特异性功能发展到从功能连接网络角度进行研究。并且研究者们开始尝试开发基于数学认知基本理论的干预方法,并采用了利用生物技术手段的新方法。基因-脑-行为的整合研究将有助于全面揭示发展性计算障碍的发生机制,而建立在系统理论基础上经过科学评估的干预手段将可能有效促进障碍者的计算能力。     

成人认知功能的发展与老化：一项控制同辈效应的横断研究

为探索成人认知功能的发展与认知老化轨迹,基于中华成人智力量表常模样本数据,统计控制教育水平和职业构成以部分消除同辈效应,考察智商和智力指数的年龄趋势。结果晶体智力指数(CI)在25~44岁间增加0.69分后缓慢递减,高低差值3.3分;注意记忆指数(AMI)在25~44岁间共减少3.3分,45岁后各组均数以3分左右的速度递减。流体智力指数(FI)和智商的年龄差异模式与AMI类似,幅度缩减。提示中国成人晶体智力在74岁前比较稳定,没有明显老化,流体智力和注意记忆能力可能在45岁开始明显线性老化。     

The effect of motion at encoding and retrieval for same- and other-race face recognition

In an experimental study, we assessed the role of motion when encoding and recognizing unfamiliar faces, using an old/new recognition memory paradigm. Our findings revealed a clear advantage for learning unfamiliar faces moving non-rigidly, compared with static faces. This advantage for motion was found with both same- and other-race faces. Furthermore, results indicate that it is more important that the face is learnt in motion than recognized from a moving clip. Interestingly, despite a reliable other-race effect being revealed, participants were able to utilize motion information exhibited by other-race faces in a manner akin to the motion advantage found for same-race faces. The implications of these findings are discussed in relation to the nature of the stored face representations, considering whether the facilitative role found here can be explained by factors other than motion per se.     

Developmental Trajectories of Maladaptive Perfectionism in Middle Childhood

The developmental trajectories of maladaptive perfectionism, along with their consequences and origins, were examined in middle childhood. A sample of Singaporean children and their parents (N = 302) were recruited for a longitudinal study when the children were 7 years old. Subsequent follow‐up assessments were made at ages 8, 9, and 11. A multimethod approach was adopted where parent reports, child reports, and observational data on a dyadic interaction task were obtained. Using latent class growth modeling, four distinct classes were obtained for critical self‐oriented perfectionism (SOP‐C), whereas two classes emerged for socially prescribed perfectionism (SPP). Children with high and/or increasing SOP‐C and SPP trajectories constituted 60% and 78% of the sample, respectively. For both SOP‐C and SPP, trajectories with high initial status were associated with higher internalizing and externalizing symptoms. Parental intrusiveness and negative parenting predicted high and/or increasing SOP‐C trajectories, whereas the child temperament dimension of surgency predicted high SPP trajectory. Both SOP‐C and SPP trajectories tended to co‐occur, suggesting a mutually reinforcing process. This study yields important findings that help advance current understanding of the emergence and developmental pathways of maladaptive perfectionism in children.     

4～6岁幼儿对口语和文字信息的信任及运用

研究以混合物分类为实验任务,探讨在面对口语和文字两种信息时,4~6岁中国幼儿的信任特点,在信任任务之后的即时和延时两个时间点上考察幼儿对所信任信息的运用,以及分析阅读水平对幼儿信息信任和运用的影响。研究结果表明:(1)4~6岁中国幼儿对不同类型信息都表现出高度信任,相较于口语信息,阅读水平高的幼儿表现出对文字信息的信任偏好;(2)幼儿在后续任务中较少运用所信任的信息,随着时间的推移,幼儿运用的口语信息持续减少,但文字信息的运用呈现先降后升的特点;(3)阅读水平在不同时间点上影响幼儿对所信任信息的运用,阅读水平低的幼儿在短时间内更多地运用口语信息,而阅读水平高的幼儿在更长时间里显著更多地使用文字信息。未来研究应进一步探究文字意识对幼儿文字信息信任和后续运用的作用。
