初中男生个体攻击性与群体攻击性的差异

运用实验法和问卷法对118名初中男学生进行攻击性的研究.比较了四种不同类型的攻击行为.包括群体之间、个体之间、群体与个体之间、个体与群体之间.结果显示:群体无论是作为攻击来源还是攻击目标都能起到增加攻击行为的情境作用;个体之间与群体之间在攻击性方面有显著差异;群体之间相互作用时表现出的攻击性远高于个体之间相互作用时表现出的攻击性:个体与群体相互作用时比个体之间相互作用时表现出更高的攻击性.     

4～5岁儿童一一对应任务中的比例效应

一一对应和数量比较是幼儿数概念发展的两个重要方面。在本研究中．40名4岁和39名5岁的儿童分别完成了不同比例数量的一一对应任务和数量比较任务。结果表明：（1）两种实验任务下均出现比例效应．说明儿童在解决一一对应问题时,仍然用数量比较的方法来进行判断;（2）任务类型的主效应显著,一一对应任务下的正确率要显著低于数量比较任务下的正确率;（3）知觉线索更多地影响数量比较任务。     

On ethical order

The existent ethical relationships are the result of the historical amalgamation of objective and subjective conditions. Ethical relationships are essential relationships in the real and rational order, which are maintained by a system of regulations on morals, laws and customs, and infused with a spirit of subjectivity. Rationality and legitimacy are the primary concerns of those relationships. A distinction between morals and ethos needs to be made when studying ethical order. Sound ethical order lies in effective regulation of morals and effective control of law. In the process of social reform, ethical order promotes social development through the dialectical movement of freedom and necessity. A harmonious society is a society which is based on legitimate and just ethical order. Translated by Cui Hui from Lunlixue yanjiu 伦理学研究 (Studies in Ethics), 2007, (5): 1–8     

If It's Difficult to Pronounce, It Must Be Risky

ABSTRACT— Low processing fluency fosters the impression that a stimulus is unfamiliar, which in turn results in perceptions of higher risk, independent of whether the risk is desirable or undesirable. In Studies 1 and 2, ostensible food additives were rated as more harmful when their names were difficult to pronounce than when their names were easy to pronounce; mediation analyses indicated that this effect was mediated by the perceived novelty of the substance. In Study 3, amusement-park rides were rated as more likely to make one sick (an undesirable risk) and also as more exciting and adventurous (a desirable risk) when their names were difficult to pronounce than when their names were easy to pronounce.     

脊柱结核个体化综合治疗的思考

近年来脊柱结核迅速增多,严重威胁着人类的健康.本文分析目前脊柱结核治疗中存在的问题,围绕这些问题,从脊柱结核的化疗,手术、围手术期处理、术后督导治疗方面综合思考个体化综合治疗在脊柱结核中的应用.通过这些分析和思考,以期引导我们用系统全面的观点治疗眷柱结核,并最终控制其流行.     

康德、黑尔与普遍主义

康德和黑尔都是伦理学的杰出代表人物,尽管一个是规范伦理学家,一个是元伦理学家,但是双方都把目光聚集在道德的形式主义研究上,并且着力于普遍主义的落脚点.两者在理论上存在诸多不同,却依然可以发现两者在理论上的先行后继的关系.     

ELOPTA: A novel microcontroller-based operant device

Operant devices have been used for many years in animal behavior research, yet such devices a regenerally highly specialized and quite expensive. Although commercial models are somewhat adaptable and resilient, they are also extremely expensive and are controlled by difficult to learn proprietary software. As an alternative to commercial devices, we have designed and produced a fully functional, programmable operant device, using a PICmicro microcontroller (Microchip Technology, Inc.). The electronic operant testing apparatus (ELOPTA) is designed to deliver food when a study animal, in this case a bird, successfully depresses the correct sequence of illuminated keys. The device logs each keypress and can detect and log whenever a test animal i spositioned at the device. Data can be easily transferred to a computer and imported into any statistical analysis software. At about 3% the cost of a commercial device, ELOPTA will advance behavioral sciences, including behavioral ecology, animal learning and cognition, and ethology.     

成功老龄化的SOC模型研究综述

本文简单回顾了关于成功老龄化研究的历史,综合阐释其定义及指标,并引入Baltes经典成功老龄化的SOC模型,详细介绍它的原理及其组成部分——选择、优化和补偿,并概述它对老龄化满意度的积极影响,最后总结了该领域研究中尚存的问题。     

犯罪行为决策的理论与研究方法

犯罪行为是犯罪人决策的结果。犯罪行为决策研究旨在通过运用认知心理学的有关原理,说明犯罪行为实施之前的行为决策过程及影响因素,其成果能为国家制定刑事政策与犯罪预防政策等提供理论依据。犯罪行为决策的理论模型主要可分为犯罪理性模型、犯罪期望效用模型和犯罪前景理论模型。犯罪行为决策的研究方法主要采用心理物理法、过程追踪法、访谈法、投射测验法和犯罪统计法等。展望未来,应进一步探讨犯罪行为决策的理性与非理性问题,并加强对犯罪行为决策的验证性研究。     

我国民众对SARS信息的风险认知及心理行为

采用分层抽样的调查方法,对全国17个城市的4231名市民进行了SARS疫情中风险认知特征和心理行为的研究。结果发现：（1）负性信息,包括患病信息和与自身关系密切的信息,更易引起民众的高风险认知; 正性信息,包括治愈信息和政府防范措施的信息,能降低个体风险认知水平。（2）我国民众5月中旬风险认知因素空间位置分析结果表明, SARS病因处于不熟悉和难以控制一端,“愈后对身体的影响和有无传染性”处于不熟悉一端,这是引起民众风险意识的主要因素。（3）结构方程分析结果表明,SARS疫情信息是通过风险认知对个体的应对行为、心理健康产生影响的, 并初步验证了风险评估、心理紧张度、应对行为和心理健康等指标对于危机事件中民众心理行为的预测作用
