国内近十年来意识和无意识关系研究的新成就

近十年来,国内掀起了从自然科学途径进行意识和无意识对比研究的新热潮,尤其在实验范式的引进、修正、完善和模型建构方面,做出了中国学者自己的贡献。错误记忆、内隐时间及不注意视盲等新领域的触及代表了国内学者在意识研究内容上的丰富。“钢筋水泥”、“意识涌现”及“车站监视室”等模型的提出,代表了中国学者在意识研究理论方面的创新。当前国内意识研究与国外基本同步,但存在着“研究领域泛化,神经机制探讨有限,跨学科整合力度有待深化”的问题。     

Interaction of a dislocation with an elliptical hole in icosahedral quasicrystals

The interaction between a dislocation and an elliptical hole in icosahedral quasicrystals is considered. An explicit expression for the complex potential is derived using the extended Stroh formalism. Based on the conformal mapping method and a perturbation technique, closed-form solutions are obtained. The field intensity factors at a crack tip and the image forces on the dislocation arising from the crack are calculated. The effects of phonon–phason elastic coupling on the mechanical behavior are also observed.     

Teaching Engineering Ethics using BLOCKS Game

The aim of this study was to investigate the use of a newly developed design game called BLOCKS to stimulate awareness of ethical responsibilities amongst engineering students. The design game was played by seventeen teams of chemical engineering students, with each team having to arrange pieces of colored paper to produce two letters each. Before the end of the game, additional constraints were introduced to the teams such that they faced similar ambiguity in the technical facts that the engineers involved in the Challenger disaster had faced prior to the space shuttle launch. At this stage, the teams had to decide whether to continue with their original design or to develop alternative solutions. After the teams had made their decisions, a video of the Challenger explosion was shown followed by a post-game discussion. The students’ opinion on five Statements on ethics was tracked via a Five-Item Likert survey which was administered three times, before and after the ethical scenario was introduced, and after the video and post-game discussion. The results from this study indicated that the combination of the game and the real-life incident from the video had generally strengthened the students’ opinions of the Statements.     

内隐刻板印象中反刻板印象信息的干预研究

该研究以性别职业刻板印象和自我-职业刻板印象的内隐联想测验（IAT）为实验材料和测量工具．通过提供反刻板印象信息为干预策略进行实验。研究表明：职业一性别刘板印象和职业一自我刻板印象层次不同,在总体上具有显著的相关;大学生在职业-性别刻板印象和职业一自我刻板印象上都存在极其显著的内隐效应,女大学生显示极强的内隐职业一自我刻板印象;在职业-自我刻板印象上,反刻板印象信息具有显著的干预作用,对男大学生的干预作用比对女大学生的大;在内隐水平上反刻板印象信息只能部分消除刻板印象;设计的[AT纸笔测验版本是可行的;在学校教育中渗透性别平等教育将是十分必要的和可行的。     

International Exchange Training in Genetic Counseling: An Exploration of the Value in Exchange Experiences

International exchange training in genetic counseling is increasing, but research examining these experiences is lacking. In this study 309 genetic counseling students and genetic counselors completed an anonymous survey investigating six major research questions: (1) How prevalent are international genetic counseling experiences? (2) What types are pursued and why? (3) What supports and barriers exist? 3) What are the demographic characteristics of individuals accruing international experience? (5) Does international experience promote professional development? and (6) Do genetic counseling students and professionals perceive international experiences as beneficial? Most respondents were Caucasian females born in one of 25 countries. The most prevalent experiences involved either clinical observation or clinical training. Common motivations for pursuing international experience were personal growth, exposure to a different healthcare system, and travel opportunities. Outcomes included professionally-relevant experience and personal growth. Barriers included finances, limited availability of opportunities, and for those without international experience, family responsibilities. Additional findings, practice and training implications, and research recommendations are provided.     

组织中的社会阻抑:概念界定、影响结果和形成机制

社会阻抑是指长期的、蓄意地妨碍个体积极人际关系的建立和维持,影响个体在工作上的成功及良好名誉的行为.文章在介绍社会阻抑概念和测量的基础上,综述了社会阻抑在心理健康、自我效能感等个人层面和组织氛围层面的消极影响;接着阐明了个体对社会阻抑行为的实施和反应一方面受到人格、认知等内在因素的影响,另一方面也受到社会情境、社会支持等外在因素的影响.未来研究需进一步加强对社会阻抑概念、测量、研究方法、影响因素等方面的深入探讨.     

亲代孕前成瘾药物暴露对子代行为的影响及其表观遗传机制

孕前成瘾药物暴露不仅危害使用者的身体健康,而且会对子代的生理行为造成影响,近年来研究发现表观遗传机制在其中发挥重要作用。孕前成瘾药物暴露会对子代的成瘾易感性和焦虑样行为造成影响,引起子代的抑郁样行为和认知受损。这些现象可能是成瘾药物通过引起亲代生殖细胞内表观遗传修饰变化所致,其中包括印记基因、神经递质系统、BDNF三个方面的表观遗传修饰变化。此外,未来除了加强以上三个方面基因的研究,也需要增加其他方面基因的研究,以及寻找能预测子代异常行为的表观遗传生物标志物。     

暴力媒体接触程度对攻击行为的影响——规范信念和移情的作用

研究引入攻击行为的规范信念和移情两个概念,使用攻击性发展稳定的大学生为被试,探讨暴力媒体对攻击行为的作用机制。采用问卷调查法,使用Anderson等人编写的暴力媒体接触程度问卷、攻击行为规范信念量表（NOBAG）、攻击问卷（AQ）和人际活动指标问卷（IRI）对来自北京、福州和成都三地的680名被试进行实地调查,了解其暴力媒体接触程度、攻击行为规范信念、攻击行为和移情能力间的关系,并在此基础上构建了暴力媒体接触程度、移情、规范信念和攻击行为的结构方程模型。研究结果表明：（1）不同性别的攻击性差异显著,男性更经常使用暴力媒体,具有更高的攻击行为规范信念,且倾向于出现攻击行为;（2）暴力媒体对攻击行为的预测作用显著,且不同媒体形式间存在差异,暴力视频游戏的作用显著强于暴力电视和暴力电影/视频;（3）规范信念可以有效预测攻击行为,在暴力媒体接触程度和攻击行为间、移情和攻击行为间起中介作用。     

Social power facilitates the effect of prosocial orientation on empathic accuracy

Power increases the tendency to behave in a goal-congruent fashion. Guided by this theoretical notion, we hypothesized that elevated power would strengthen the positive association between prosocial orientation and empathic accuracy. In 3 studies with university and adult samples, prosocial orientation was more strongly associated with empathic accuracy when distinct forms of power were high than when power was low. In Study 1, a physiological indicator of prosocial orientation, respiratory sinus arrhythmia, exhibited a stronger positive association with empathic accuracy in a face-to-face interaction among dispositionally high-power individuals. In Study 2, experimentally induced prosocial orientation increased the ability to accurately judge the emotions of a stranger but only for individuals induced to feel powerful. In Study 3, a trait measure of prosocial orientation was more strongly related to scores on a standard test of empathic accuracy among employees who occupied high-power positions within an organization. Study 3 further showed a mediated relationship between prosocial orientation and career satisfaction through empathic accuracy among employees in high-power positions but not among employees in lower power positions. Discussion concentrates upon the implications of these findings for studies of prosociality, power, and social behavior.
