Social neuroscience of child and adolescent depression

The social neuroscience of child and adolescent depression is inherently multidisciplinary. Depressive disorders beginning early in life can have serious developmental and functional consequences. Psychopathology research has described depression's defining clinical and contextual features, and intervention research has characterized its response to treatment and prevention programs. Neuroendocrine, electrophysiological, and neuroimaging studies have identified core neurobiological aspects of early-onset mood disorders. These areas are reviewed using a developmental social neuroscience perspective for integrating disparate observations. The paper introduces a dynamic adaptive systems framework, and it discusses hedonic capacity, stress sensitivity, ruminative self-focus, and attentional impairments as fundamental components of mood disorders.     

Evolution and Two Popular Proposals for the Definition of Function

Summary  In the biological realm, a complete explanation of a trait seems to include an explanation in terms of function. It is natural to ask of some trait, “What is its function?” or “What purpose in the organism does the particular trait serve?” or “What is the goal of its activity?” There are several views concerning the appropriate definition of function for biological matters. Two popular views of function with respect to living things are Cummins’ organizational account and the Griffiths/Godfrey-Smith modern history account. Whereas Cummins argues that a trait functions so as to contribute to the general organization of some organism’s present structure, Griffiths, and Godfrey-Smith argue that a trait functions because of its fitness with respect to the organism’s recent evolutionary history. In this paper, I show how these accounts can be made compatible and compliment one another. Given that structure, organization, operational flexibility, function, and evolutionary history are all factors to be considered in an organism’s makeup, we should expect that the traits of an organism function the way they do because such traits presently contribute to the overall organization of the organism (Cummins) as well as were selected for in the organism’s species’ recent ancestry (Griffiths/Godfrey-Smith).     

Capturing the Naturally Occurring Superior Performance of Experts in the Laboratory: Toward a Science of Expert and Exceptional Performance

ABSTRACT— Expertise researchers have traditionally shied away from studying the highest levels of achievement in favor of studying basic cognitive processes, such as memory and categorization. In this article, we present a different approach that is focused on capturing superior (expert) performance on representative tasks that reveal the essential characteristics of expertise in a given domain. In domains where expert performance is measurable, acquisition is gradual and the highest levels are only attained after 10 years of intense preparation—even for the most "talented." Analyses of reproducibly superior performance show that it is mediated by physiological adaptations and cognitive skills acquired as a result of the cumulative effects of special practice activities (deliberate practice). It appears that the genes necessary to attain such adaptations and expert skills can be activated in healthy children—the only clear exceptions to date being genes that control body size and height. Our knowledge of how experts acquire their superior skills provides insights into the potential for human adaptation and skill acquisition and has important implications for theories of the structure of general and expert cognition, as well as for training interventions in applied psychology and education.     

流动儿童社会适应的研究:现状、问题及解决办法

参照国外关于移民儿童社会适应研究的现状,对国内流动儿童社会适应的研究现状进行了回顾,指出了国内该研究领域存在的几个不足:(1)评估指标不全面;(2)评估存在缺陷取向;(3)忽视个体差异的问题;(4)研究设计与社会适应的过程理论相背离;(5)教育安置方式对流动儿童社会适应的影响未得到应有的重视。最后提出了解决以上问题的办法。     

自尊和心理控制源对留守儿童社会适应的影响研究

本研究以积极心理学理论为依据,采用量表法,对农村留守儿童和非留守儿童进行了比较研究。结果表明:留守儿童和非留守儿童在自尊、心理控制源以及社会适应性上都存在着显著性差异。在该研究结果上,深入分析了高自尊和内控归因这两种积极心理品质作为心理弹性的保护性因子对留守儿童社会适应性所发挥的作用。     

中国青少年心理健康素质·适应状况的研究

应用《青少年心理健康素质调查表·适应分量表》,对全国23个省、市、自治区44063名青少年的适应状况进行了调查。结果发现：（1）青少年的适应状况处于较好的水平。（2）青少年适应及情绪适应、学习适应、人际适应、社会适应和生活适应等各维度得分在小学五年级较高,从初中阶段开始呈下降趋势,高中阶段继续下降,到大学阶段又逐渐回升。生理适应维度得分在小学五年级、初中和高中阶段较高,大学阶段下降至最低。     

The Client's Perspective of Genetic Counseling—A Grounded Theory Study

Previous studies of genetic counseling have mainly focused on outcomes defined by researchers or service providers, and have frequently related to changes in reproductive behavior and/or client knowledge. A longitudinal study of 43 families referred to a clinical genetic service was undertaken to ascertain client needs and expectations of the service, and to identify relevant outcomes from the clients' perspective. Semistructured interviews were conducted with each client, prior to and after genetic counseling. The transcribed interviews were analyzed using grounded theory. The need for certainty emerged as a powerful factor that motivated clients to pursue the genetic referral. The client's lay knowledge of the condition, satisfaction of the need for certainty, and the formation of a personalized relationship between the client and the genetics staff significantly influenced the central outcome, identified as a change in the client's psychological adaptation to the genetic condition in the family.     

数量适应后效的皮层映射特征

本研究探讨了观察者与观察目标存在相对运动时视觉系统对目标数量特征的适应后效的皮层映射特征, 并与对比度适应后效的映射规律进行比较。包括两项实验。其中, 实验一要求被试在适应目标后转换注视点, 考察眼跳后相同和不同视网膜区域以及相同和不同空间区域的适应后效, 发现数量适应后效具有部分空间-皮层映射特性, 而对比度适应后效则表现出完全的视网膜-皮层映射特征。实验二采用固定的注视点, 考察目标运动后目标原位置和新位置区域的适应后效, 发现数量适应后效不完全依赖于视网膜-皮层映射, 它可以“追随”客体运动重新映射到新的位置, 表现出基于客体映射的特征, 而对比度适应后效则完全依赖于视网膜-皮层映射, 不能“追随”客体移动在目标新位置重新形成映射。两项实验结果提示, 相对于对比度等低级表面特征而言, 数量特征对目标的描述涉及更高的加工水平, 它可以与观察目标的相对运动信息进行整合, 且这种整合在眼跳和非眼跳的观察条件下都可发生。     

流动儿童心理韧性对文化适应的影响:社会认同的中介作用

本研究旨在探讨流动儿童心理韧性、社会认同及文化适应的关系。采用青少年心理韧性量表、流动儿童社会认同量表、流动儿童文化适应困难量表对北京市932名流动儿童进行了调查。经过分析发现：（1）女生、未转学、家庭收入高、父母教育程度高、公立学校的流动儿童文化适应更好;（2）流动儿童的心理韧性对其文化适应的直接预测效应显著;（3）流动儿童的心理韧性可以分别通过老家总认同和城市总认同间接影响文化适应,也可以通过老家总认同和城市总认同的整合更好地间接影响文化适应。     

创造力有其“阴暗面”

创造力有其“阴暗面”。从产品角度而言,创造力可产出伤害性或消极的产品;从个体角度而言,高创造力者可能具有一些消极特征,如精神疾病易感性强、宜人性差、说谎、不诚信等;从情境角度而言,高创造力表现可能与不信任感、生存危机感、社会拒绝等消极因素有关。未来研究应开发高生态效度的恶意创造力测评工具,改进计算恶意创造力水平的算法,探索消极个体特征和消极情境因素作用于创造性思维的认知与神经机制。
