任务切换机制研究的理论争议与整合

任务切换是执行控制的一种重要功能。切换代价是量化执行控制持续时间的指标。并广泛应用于各个研究领域。但是切换代价在多大程度上体现了执行控制的作用,仍然还存在争论．当前主要存在任务设置重构、任务设置惯性和联结竞争三种理论。本文首先介绍了三种理论的基本观点和实验证据,以及对任务切换加工机制的分析;其次阐明了对三种理论进行整合的相关研究;最后分析了进一步研究的方向。     

Gender Differences in Stress and Coping among Elderly Patients on Hemodialysis

The study investigated whether gender differences in the stressor, coping strategies, and how they associate stress and copings among 875 elderly patients undergoing hemodialysis in Taiwan. Chi-square tests, MANOVA and Structural Equation Modeling were used to attain the research purposes. The results found that the women had reported higher stress in response to physical and vessel problems and higher scores in using emotion-oriented and support-seeking coping strategies, while the men reported higher stress in reproductive system functioning and higher score in using avoidance as a coping strategy. Furthermore, the results from SEM demonstrated that after controlling for patient characteristics, no statistical difference was found between the two groups with regard to their linking of stress and coping strategies.     

方证研究与中医现代化

具有整体观念和辩证思维特征的中医药实践经验是中医学的基础,方证则是中医实践的精华.我们应当将研究的重点放在中医学的方证体系上.应当改变传统的方证研究模式,采用现代科学提供的方法深入研究临床现象及其与方药对应的客观规律,继承老经验,发现新经验,建立开放的中医学方证体系.

Category width and differentiation in semantic categories

The hypothesis that the judgemental categorizing behaviour measured by Pettigrew's Category-Width scale is linked to semantic categorization is investigated. Individual differences in broad vs. narrow categorizing behaviour measured by the C-W scale are reconceptualized within the framework of Rosch's (1977) theory of human categorization. Two extreme groups on the C-W scale, broad categorizers and narrow categorizers, were selected as subjects. One experiment employed a short-term release-from-proactive-inhibition paradigm. The amount of discrepancy in recall between the preshift and the shift trials was used as an index to perceived semantic distance. The result showed that narrow categorizers perceived the same fuzzy items in a semantic category as less similar to the good exemplars of that category than broad categorizers did. In a further experiment using a semantic-categorization technique, narrow categorizers judged the same fuzzy items as category members less frequently than broad categorizers did, indicating that narrow categorizers possess more differentiated semantic categories than do broad categorizers. These findings are seen as an extension of the differential categorizing behaviour on artificial categories in the C-W scale to semantic categorization for which there is a pre-existing system.     

Do Parent–Adolescent Discrepancies in Family Functioning Increase the Risk of Hispanic Adolescent HIV Risk Behaviors?

In the family‐based prevention science literature, family functioning, defined as positive parenting, parental involvement, family cohesion, family communication, parental monitoring of peers, and parent–adolescent communication, has been shown to ameliorate HIV risk behaviors in Hispanic youth. However, the majority of studies have relied solely on parent or adolescent reports and we know very little about parent–adolescent family functioning discrepancies. Therefore, the purpose of this study was to examine whether and to what extent parent–adolescent discrepancies in family functioning increased the risk of HIV risk behaviors, including substance use and sexual risk behaviors, and whether these associations vary as a function of acculturation and youth gender. A total of 746 Hispanic 8th grade youth and their primary caregivers were included in the study. Structural equation modeling findings indicate that parent–adolescent family functioning discrepancies are associated with an increased risk of Hispanic adolescent HIV risk behaviors, including lifetime and past 90‐day alcohol and illicit drug use, and early sex initiation. In addition, study findings indicate that results vary by acculturation and youth gender. Findings are discussed in the context of existing family‐based research and practice in preventing and reducing HIV risk behaviors among Hispanic youth and their families.     

Confucian Dynamism,the Role of Money and Consumer Ethical Beliefs: An Exploratory Study in Taiwan

Consumer ethics is the moral principles and standards that guide consumers to determine the certain consumption behaviors are ethically right or wrong. Whereas cultural and personal dimensions are crucial constructs affecting individual ethical attitudes and behaviors, few studies consider Confucian dynamism and the role of money in consumer ethics. Confucian dynamism, a cultural dimension based on Confucianism, has played a central role in guiding moral obligations and ethics in human relations in several East Asian countries. Thus, this study tested its hypotheses using a sample of 521 respondents obtained via a systematic random sampling technique. The authors find that individuals with a higher tendency to Confucian dynamism are less tolerant of unethical practices. These findings also show that the role of money partially influences consumer ethical beliefs. Finally, we examine the impact of demographic variables and find age and education affect consideration of ethical values.     

基础认知与社会认知中内隐过程及其脑机制*

认知过程及其脑机制是心理学研究的重要内容。社会认知是人们在社会生活中对他人行为的意图及情感的认识,是人际互动的重要方面,具有深刻的理论和实践意义。本文全面深入地对社会认知和基础认知中自动加工过程进行了研究综述,对基础认知与社会认知的研究方式进行了比较。自动加工过程是社会认知和基础认知中都存在的重要过程,从脑机制研究角度,相关的电生理学指标(如N400等)都可以作为研究的指标来考察社会认知中的自动加工过程。本文从社会认知与基础认知的比较入手,介绍了各种领域的研究方法,特别是事件相关电位技术等认知神经科学研究方法。     

青少年时间管理倾向相关因素的研究

本研究探讨时间管理倾向与学生学业成绩、自我价值感和主观幸福感三者的关系,进一步验证个人的时间管理倾向与生活质量的关系。对重庆和成都两地三组1387名大、中学生(重庆312名中学生、339名大学生,成都736名中学生)的问卷调查研究发现：(1)时间监控观对学业成绩具有一定的预测作用,时问价值感和时间效能感是通过时间监控观来影响学业成绩。(2)时间管理倾向各维度与总体、一般和特殊自我价值感之间存在显著的正相关。随着自我价值感抽象程度的降低,时间管理倾向对自我价值感的影响程度也就越大。(3)时间管理倾向各维度与积极情绪之间存在显著正相关,与消极情绪之间存在显著负相关。时间管理的好坏可能是影响主观幸福感的一个重要因素。     

应当关注时间心理无意识的研究

随着心理无意识研究在记忆、学习和思维等领域的兴起,内隐时间认知也逐步成为时间心理学中的一个研究热点。本文分析了探究内隐时间认知的四种方法:分离范式、序列学习范式、表征动量范式和计时分布相关范式,指出内隐时间认知实验范式在无意识时间人格与社会心理学中的研究也是有相当前景的。
