二次线索化对基于形状返回抑制的影响

采用3×2被试内设计考察辨别任务中二次线索化对基于形状返回抑制的影响。结果发现:无二次线索化,IOR出现在长SOA(1000ms)时;有二次线索化,IOR出现在短SOA(500ms)时;两种情况下当SOA足够长(1400ms),返回抑制现象消失。Tipper的抑制机制模型可以恰当的解释这一现象。     

心理研究中统计方法应用的元分析——以《心理学报》《心理科学》(1998-2008)统计方法应用为例

统计方法在心理研究中得到了广泛的应用。统计方法的应用,除了具备一定的统计方法知识外,还应当了解统计方法应用的必要前提条件。通过调查、分析国内最具代表性的两种杂志《心理学报》、《心理科学》(1998 2008)应用了统计方法的论文(或报告),主要了解哪些统计方法得到最多的应用以及发现应用中存在的一些问题,并对此作了评述。目的是使心理学研究者在心理研究中能更好地应用统计方法分析问题,解决问题。     

大学生性别角色形成研究——双性化与未分化个案的对比

采用刘电芝编制的中国大学生性别角色量表(CSRI-50),甄别出双性化、未分化和单性化被试。在此基础上,对双性化和未分化个案进行深度访谈,以探究影响大学生性别角色形成的主要因素。结果表明父母教养方式、父母个性特点、父母期待、亲子关系、玩伴和自我期待是性别角色的六大影响因素。其中家庭因素最为重要,在家庭因素中父母处于核心地位。通过双性化和未分化个案的比较研究,表明教养者的温柔、鼓励,民主型教养方式,良好的家庭气氛,兄弟姐妹间友好关爱,积极的自我调节有利于双性化的发展;反之,则加剧未分化的形成。     

Proposed Strategies for Teaching Ethics of Nanotechnology

Nanotechnology and nanosciences have recently gained tremendous attention and funding, from multiple entities and directions. In the last 10 years the funding for nanotechnology research has increased by orders of magnitude. An important part that has also gained parallel attention is the societal and ethical impact of nanotechnology and the possible consequences of its products and processes on human life and welfare. Multiple thinkers and philosophers wrote about both negative and positive effects of nanotechnology on humans and societies. The literature has a considerable amount of views about nanotechnology that range from calling for the abandonment and blockage of all efforts in that direction to complete support and encouragement in hopes that nanotechnology will be the next big jump in ameliorating human life and welfare. However, amidst all this hype about the ethics of nanotechnology, relatively less efforts and resources can be found in the literature to help engineering professionals and educators, and to provide practical methods and techniques for teaching ethics of nanotechnology and relating the technical side of it to the societal and human aspect. The purpose of this paper is to introduce strategies and ideas for teaching ethics of nanotechnology in engineering in relation to engineering codes of ethics. The paper is neither a new philosophical view about ethics of nanotechnology nor a discussion of the ethical dimensions of nanotechnology. This is an attempt to help educators and professionals by answering the question of how to incorporate ethics of nanotechnology in the educational process and practice of engineering and what is critical for the students and professionals to know in that regard. The contents of the presented strategies and ideas focus on the practical aspects of ethical issues related to nanotechnology and its societal impact. It also builds a relation between these issues and engineering codes of ethics. The pedagogical components of the strategies are based on best-practices to produce independent life-long self-learners and critical thinkers. These strategies and ideas can be incorporated as a whole or in part, in the engineering curriculum, to raise awareness of the ethical issues related to nanotechnology, improve the level of professionalism among engineering graduates, and apply ABET criteria. It can also be used in the way of professional development and continuing education courses to benefit professional engineers. Educators and institutions are welcome to use these strategies, a modified version, or even a further developed version of it, that suits their needs and circumstances.     

Refining the two‐parameter testlet response model by introducing testlet discrimination parameters

For testlet response data, traditional item response theory (IRT) models are often not appropriate due to local dependence presented among items within a common testlet. Several testlet‐based IRT models have been developed to model examinees' responses. In this paper, a new two‐parameter normal ogive testlet response theory (2PNOTRT) model for dichotomous items is proposed by introducing testlet discrimination parameters. A Bayesian model parameter estimation approach via a data augmentation scheme is developed. Simulations are conducted to evaluate the performance of the proposed 2PNOTRT model. The results indicated that the estimation of item parameters is satisfactory overall from the viewpoint of convergence. Finally, the proposed 2PNOTRT model is applied to a set of real testlet data.

"道德人"及其生成的元问题审思

元是指根本,元问题是指根本的问题。道德人就是那些能够在实践理性精神主导下自觉作出有益于他人的却与自身利益无关甚至是有违自身利益的行为或活动的人。道德人的元问题就是人的本质和人的价值是什么的问题,它回答了道德人何以为道德人之根本所在。在当代,人的解放已经到了这样一个阶段:关于道德人评判的思维元模式是超越了主体论工具理性的主体间论。     

EPQ信度概化的跨文化比较及其启示

对中国7种主要的心理学杂志,于1998-2008年间发表的与EPQ有关的研究报告或论文做信度概化分析,并与Caruso等人对其他国家的EPQ信度概化分析结果作比较。分析结果表明：中外心理量表使用者都存在严重的“信度引入”的状况;分量表的分数的标准差是信度系数最重要的预测变量;但其他预测变量有所不同。提供的启示是：使用心理量表时一定要报告当前样本的信度系数;不符合心理量表特性要求而增加项目,不一定能提高测验结果的信度。
