情绪和社会行为的迷走神经活动基础

Porges基于自主神经进化观点提出的多迷走神经理论, 区分了无髓鞘迷走神经与髓鞘迷走神经的不同功能。认为对心脏等起调控作用的髓鞘迷走神经, 经由进化逐渐与调控头面部肌肉的脑神经之间产生了神经上的联系, 成为情绪和社会行为的神经基础。已有的相关实证研究表明, 髓鞘迷走神经与个体的情绪表达与调节、社会行为以及情绪与社会行为障碍密切相关。较低的迷走神经张力、较低的迷走抑制与较低的情绪调节能力相关; 迷走抑制较高的学前儿童有较少的行为问题以及较好的社交技能; 焦虑障碍的个体表现出较低的基线迷走张力以及较低的迷走抑制水平等。多迷走神经理论及其实证研究的结果, 对于推动情绪和社会行为的自主神经基础研究具有重要的意义。     

严谨性的结构及其应用研究述评

严谨性(Conscientiousness)是指个体在按照社会规范的要求控制冲动的倾向、以任务和目标为导向、先思后行、延迟满足以及遵守规范和纪律等方面上的个体差异。由于其在应用心理学领域(如, 组织管理心理学)的重要作用而被广泛而深入的研究, 主要内容涉及严谨性对工作绩效和其他工作相关行为的的预测、对健康行为和寿命的预测、对学业表现的预测等方面。文章全面回顾了近年来严谨性的结构及其在管理、教育和健康领域的相关研究, 并指出将来的研究应进一步深入探索严谨性的次级结构、测量工具的编制、严谨性与绩效间关系的假设、严谨性与寿命和健康行为之间的关系等问题。     

工作中的主动性行为的回顾与展望

工作中的主动性行为是旨在引起或促使变革的行为。它包括三个成分：自发性、前瞻性和变革性。组织行为学中得到较多关注的主动性行为包括主动改进工作方法、主动解决问题、个人主动性、寻求个性化的契约关系以及主动寻求反馈等行为。不同类型的主动性行为可以整合为三个高阶分类, 与角色外行为、适应性行为等有本质区别。主动性行为研究的逻辑关系网络包括前因变量、结果变量以及可能的调节变量。未来研究应基于中国特殊的文化和经济背景, 进一步整合主动性行为的内涵, 拓展研究领域。

Rats’ novel object interaction as a measure of environmental familiarity

Environmental familiarization is a learning phenomenon embedded within most tasks used to study learning and motivation. Given its prevalence there is surprisingly little systematic behavioral research on factors affecting familiarization. The six experiments reported in the present report used rats’ tendency to interact more with a novel object in a familiar than in a novel environment as a measure of environmental familiarization. We found that 3 min of exposure to the environment was sufficient to increase object interaction above unfamiliar controls even when testing occurred up to 48 h after initial exposure to the environment; 1 or 1.5 min of exposure was not sufficient. Also, in the brief 2 min test, 10 min of environment exposure did not appear to increase object interaction above the 3-min condition. The 3-min of environment exposure was sufficient for familiarization whether environment exposure occurred in one 3 min placement or two 1.5 min placements. Environmental familiarization as measured by object interaction was also sensitive to ‘interference’ manipulations. That is, a distinct object present during initial exposure to the environment produced a level of object interaction in testing comparable to an unfamiliar control. Similarly, exposure to a second distinct alternate environment immediately after, but not before, initial exposure to the test environment partially disrupted environmental familiarization. In sum, object interaction might serve as a useful measure for studying processes mediating environmental familiarity.     

Classroom observations of students with and without ADHD: Differences across types of engagement

The current study examined the behaviors related to academic engagement exhibited by students with ADHD during instruction in math and reading. A total of 155 students (92 ADHD, 63 recruited controls) in grades 1 through 4 participated in the study. Results revealed that students with ADHD exhibited statistically significant lower rates of academic engagement and higher rates of off-task behaviors than recruited controls and randomly selected peer comparisons. Specifically, students with ADHD exhibited statistically significant lower rates of passive academic engagement (PET) than recruited controls and peer comparisons; however no group differences were found with regard to active engaged time (AET). In addition, students with ADHD exhibited lower rates of AET than PET, a finding observed among both recruited controls and randomly selected peer comparisons. Implications for research and practice are discussed.     

Functional assessment, collaboration, and evidence-based treatment: Analysis of a team approach for addressing challenging behaviors in young children

This study examined the effects of functional assessment and positive behavior support on classroom behaviors of young children. An experimental program, entitled FACET, was implemented by school-based teams in pre-kindergarten through first-grade classrooms. Observations of child behaviors and classroom variables were compared between experimental and control classrooms. Results indicate that children in FACET classrooms made significant gains from baseline to post-intervention and exhibited a higher occurrence of positive behaviors and fewer negative behaviors compared to control children. Behavior gains were positively correlated with the level of treatment fidelity. These findings support the effectiveness of an intervention that incorporates functional assessment, collaboration, and evidence-based treatment with young children who exhibit challenging behaviors.     

ANIMALIA,HOMO, AND THE KINGDOM OF GOD

Abstract. I selectively and critically review the state of knowledge about human evolution and the place of humans vis‐à‐vis living apes, with emphasis on bipedal posture and locomotion, expansion of the brain and associated cognitive capacities, speech, tool behavior, culture, and society. I end with a personal perspective on God and Heaven.     

Stress and Adaptation

ABSTRACT— Animal models have contributed considerably to the current understanding of mechanisms underlying the role of stress in health and disease. Despite the progress made already, much more can be made by more carefully exploiting animals' and humans' shared biology, using ecologically relevant models. This allows a fundamental analysis of factors modulating individual adaptive capacity and hence individual vulnerability to disease. This article highlights an emerging scientific approach that uses a framework of interpretation that is more biologically oriented than previous approaches, to evaluate both the adaptive and maladaptive nature of the stress response in relation to existing environmental demands.
