多巴胺相关基因甲基化、家庭环境与创造力的关系

“遗传与环境”的争论一直是创造力研究的核心问题, 但目前对于环境以及遗传与环境交互作用对创造力影响的分子生物机制还未有研究涉及。近年来, 随着表观遗传学的兴起, 揭示影响心理行为的表观遗传机制现已成为心理学研究的热点。作为环境与基因组之间的纽带, 表观遗传学研究为揭示环境以及遗传与环境交互作用对创造力影响的分子生物机制提供了机遇。本研究以多巴胺相关基因、家庭环境以及两者对于创造力的交互作用为切入点, 对影响创造力的表观遗传机制进行考察, 并在此基础之上, 对环境以及遗传与环境交互作用对创造力影响的分子生物机制进行探索。具体研究内容包括：(1)通过对多巴胺相关基因甲基化模式与创造力关系的系统考察, 筛选出甲基化模式与创造力有关的基因; (2)对筛选出的基因, 进一步考察其甲基化模式在家庭环境及其遗传多态性与家庭环境交互作用对创造力影响中的中介作用。本研究有助于揭示创造力的表观遗传机制, 深化关于遗传与环境对创造力影响的作用机制的理解。     

自我损耗对攻击行为的影响:复愈性环境的作用

本研究采用实验(stroop任务和竞争反应时任务)和问卷(积极情感消极情感量表)相结合的方法,探讨复愈性环境对自我损耗后攻击性行为的影响。结果发现:高损耗组反应性攻击行为显著大于低损耗组,两组主动性攻击行为差异不显著;观看复愈性环境和非复愈性环境后,复愈性环境组反应性攻击行为显著低于非复愈性环境组,主动性攻击行为两组无差异。结果表明:自我损耗后会产生情绪上的不良表现,反应性攻击行为增多,而主动性攻击行为不受损耗影响;自我损耗后观看复愈性环境,能够缓解情绪上的不良表现,增加认知资源,从而减少攻击行为。     

Development and Content Validity of the Participation and Sensory Environment Questionnaire

Qualitative methodology was used to develop items for a questionnaire designed to examine the perspectives of parents regarding the impact of the sensory environment on participation for children aged 3 to 5 who have autism spectrum disorders. A total of 34 parents/caregivers of children with autism spectrum disorders and 8 experts in autism spectrum disorders and/or measurement completed qualitative interviews for concept, content review, and cognitive interviewing. The result was a pool of 35 items for home/community domains for 3 scales. The outcome of this study was the development and content validation of the Participation and Sensory Environment Questionnaire.     

NR3C1基因Bcl1多态性与青少年抑郁：压力性生活事件的调节作用

迄今,有关抑郁的基因×环境交互研究多数基于“单胺缺陷假说”,相对较少有研究以“HPA轴假说”为框架考察抑郁的遗传机制,且忽视了基因-环境相关的影响。本研究对1081名青少年进行追踪研究,考察NR3C1基因Bcl1多态性与压力性生活事件对抑郁的影响。结果发现,经历较多压力性事件时,C等位基因携带者的抑郁水平显著高于GG纯合子携带者;经历较少压力性事件时,不同基因型携带者的抑郁水平无差异。此外,通过区分独立性压力性事件和预测早期抑郁进一步排除了基因-环境相关的影响,在一定程度上验证了结果的可靠性。     

Real-time detection of drivers’ texting and eating behavior based on vehicle dynamics

With rapid advancement in cellphones and intelligent in-vehicle technologies along with driver’s inclination to multitasking, crashes due to distracted driving had become a growing safety concern in our road network. Some previous studies attempted to detect distracted driving behaviors in real-time to mitigate their adverse consequences. However, these studies mainly focused on detecting either visual or cognitive distractions only, while most of the real-life distracting tasks involve driver’s visual, cognitive, and physical workload, simultaneously. Additionally, previous studies frequently used eye, head, or face tracking data, although current vehicles are not commonly equipped with technologies to acquire such data. Also those data are comparatively difficult to acquire in real-time during traffic monitoring operations. To address the above issues, this study focused on developing algorithms for detecting distraction tasks that involve simultaneous visual, cognitive, and physical workload using only vehicle dynamics data. Specifically, algorithms were developed to detect driving behaviors under two distraction tasks – texting and eating. Experiment was designed to include the two distracted driving scenarios and a control with multiple runs for each. A medium fidelity driving simulator was used for acquiring vehicle dynamics data for each scenario and each run. Several data mining techniques were explored in this study to investigate their performance in detecting distraction. Among them, the performance of two linear (linear discriminant analysis and logistic regression) and two nonlinear models (support vector machines and random forests) is reported in this article. Random forests algorithms had the best performance, which detected texting and eating distraction with an accuracy of 85.38% and 81.26%, respectively. This study may provide useful guidance to successful development and implementation of distracted driver detection algorithms in connected vehicle environment, as well as to auto manufacturers interested in integrating distraction detection systems in their vehicles.     

Développement et première validation d’une Échelle de Satisfaction Environnementale au Travail (ESET)

Our article presents the results of three studies carried out to develop and validate a scale to measure satisfaction with the work environment (ESET). Environmental satisfaction refers to the way people evaluate their workplace and has become a central concept in environmental psychology. However, so far, it has been little explored in an organizational framework. Our study aims to fill that gap by drawing up a French scale of environmental satisfaction at work based on an overall view of satisfaction toward the work environment. A systemic approach needs to be taken, covering the different spaces that make up these work environments, including the work-station, the office space, the working area and the external environment. Participants were 143 office workers in different job sectors. Confirmatory analysis showed that our environmental satisfaction at work questionnaire had good psychometric qualities.     

学校心理环境对小学4～6年级学生学业表现的作用及条件

本研究基于具有良好全国代表性的中国儿童青少年心理发育特征数据库,使用多水平建模,分析了来自全国100个区县421所学校的心理环境特征对10826名小学4~6年级学生学业表现的影响途径及其发挥作用的条件。研究结果表明:(1)小学4~6年级学生学习动机和态度及学业成绩中分别有10.0%和33.3%的变异来自学生个体以外的学校因素。(2)在控制学生年级、性别、家庭背景和学校所在地、师资、学校学生总体家庭社会经济地位(SES)等基本特征后,学校总体和学生个体知觉两个层次的学校心理环境对学生学习动机和态度的影响均显著大于其对学生学业成绩的影响;与个体知觉到的心理环境相比,学校总体心理环境对学生学业成绩的作用相对较强。(3)学校总体心理环境对学生学业表现的影响受到学校所在地、学校师资水平、学校学生总体社会经济地位的显著调节。学校总体心理环境对处于师资水平较低、平均家庭年收入较低学校学生的学习动机和态度具有相对更强的保护作用;对处于农村、师资水平较低、平均家长文化水平较低学校学生的学业成绩具有相对更强的保护性作用。上述结果表明,学校总体心理环境对学生学业表现具有重要影响,个体知觉到的心理环境仅部分中介其作用;且学校总体心理环境对学生学业表现的作用强度受到学校所在地、师资水平和学校学生总体社会经济地位的调节。     

幼儿园教师的心理健康:对基于SCL-90量表研究的元分析

症状自评量表(SCL-90)在过去15年里广泛用于幼儿园教师心理健康状况调查,然而调查结论却很不一致。为了综合这些相互矛盾的调查结果,分析其原因,37项原始研究(含42个独立样本)进入了元分析。结果显示:(1)幼儿园教师的SCL-90得分与常模没有显著差别,明显低于中小学教师;(2)城镇教师和农村教师、公办教师与民办教师的得分可能有差异;(3)离婚率、教育经费投入,以及出生死亡率与幼儿园教师的SCL-90得分有显著相关。幼儿园教师在心理健康积极端的表现,以及压力–资源–心理健康之间的因果关系在未来研究中需要更多关注。     

Power-mapping—I. Background and basic methodology

Clinical and community psychology have yet to work out the full implications of taking seriously the structuring by power of the individual's social environment. Even the factor of social class has received little more than superficial attention. Some suggestions are offered as to why this might be so, and a theoretical framework for understanding psychological distress strictly as the result of the operation of social power is developed. A simple technique of ‘mapping’ power is outlined as a means for furthering such an understanding. © 1997 John Wiley & Sons, Ltd.
