Empowerment praxis in community coalitions

Community coalitions address a wide variety of community problems, espousing a community development processes that promotes individual and collective self-determination. They offer a promising venue for the study of empowerment of individuals and organizations. This study utilizes data from members of 35 community coalitions organized for the prevention of alcohol and other drug problems to address the following questions: What individual characteristics are related to the psychological empowerment of coalition members? What organizational characteristics are related to the collective empowering of members? What organization characteristics are related to a coalition being organizationally empowered to succeed in achieving its objectives? At the individual level, psychological empowerment was most strongly related to individuals' participation levels, sense of community, and perceptions of a positive organizational climate. At the group level, the strongest predictors of collective empowering (our operationalization of the empowering organization) were net benefits of participation, commitment, and positive organization climate. Psychological empowerment and positive organizational climate were the two predictors of organizational effectiveness (the empowered organization). Implications and limitations of these findings are discussed.     

Drugs and punished responding I: rate-dependent effects under multiple schedules

The effects of drugs were studied in pigeons whose responses were punished with electric shock during one component of a multiple fixed-interval 5-min fixed-interval 5-min schedule of food presentation. Most of the drugs analyzed for rate-dependent effects increased low rates of both punished and unpunished responding, while increasing higher rates less, or decreasing them; however, low rates of punished responding sometimes were increased more by pentobarbital, diazepam, and chlordiazepoxide than were matched rates of unpunished responding. In contrast, d-amphetamine and chlorpromazine usually increased low rates of unpunished responding more than matched rates of punished responding. These two drugs also decreased high rates of unpunished responding less than they decreased high rates of punished responding. Thus, the effects of drugs on punished responding depend on the control rate of punished responding; however, the rate-dependent effects of drugs on punished responding are not always the same as they are for unpunished responding.     

Phencyclidine discrimination in the pigeon using color tracking under second-order schedules

Pigeons were trained to track different key colors, depending on whether they had been injected with phencyclidine or saline prior to the session. A second-order schedule was used to generate large numbers of responses prior to the initial food delivery. The procedure offers several advantages over traditional procedures for studying drug discrimination.     

Cardiac conditioning and extinction inMacaca mulatta during block of the CR by cardiac pacing

Previous work has shown that behavior acquisition within the Pavlovian paradigm occurs in the absence of responding,i.e., when conditional and unconditional responses are blocked during training. The parallel question of extinction under response blocking has received less attention. The experiments reported here find that a cardiac CR can be conditioned and extinguished even when rate changes are prevented by cardiac pacing during acquisition and extinction procedures. This finding suggests that the cardiac CR is established independently of peripheral innervations, and that “feedback” from the changing response is not necessary for Pavlovian learning of this sort to occur.     

汉语因果复句的心理表征项目互换效应研究

采用句子-图画验证任务(sentence picture verification task)探讨了汉语因果复句的心理表征项目互换效应。结果表明,汉语因果复句的项目表达顺序为"结果→原因"时,所形成的心理表征中项目发生互换,其结果为"原因→结果"。本研究结果初步表明,读者理解汉语因果复句是一个按照"原因→结果"固定方向进行系列加工的认知过程。     

Women's language: Uncertainty or interpersonal sensitivity and emotionality?

Six differences in linguistic behavior in same-sex and mixed-sex problem-solving groups were explored. Small groups of all women, all men, and mixed sex were run and videotaped. Linguistic behavior was assessed through a content analysis of four syntactic categories: intensifiers, modal constructions, tag questions, and imperative constructions in question form. Support was found for the hypothesis of Key (1975) and Lakoff (1975) that women, as compared with men, use more linguistic categories that connote uncertainty. Support was also found for these authors' hypotheses that (1) women use more linguistic forms that connote uncertainty when men are present than when men are absent, and (2) men are more likely to interrupt women than women are likely to interrupt men. The results are discussed from the perspectives of women's role (supportive behavior and minority status) and women's culture (interpersonal sensitivity and emotionality).This report is a revision of a paper presented at the Pioneers for Century III Conference, Cincinnati, Ohio, April 1976.     

冲突对绩效的影响：个体、团队宜人性的调节作用

以往个体和团队冲突研究主要考察了个人特征或团队特征对冲突结果的影响, 而尚未充分关注冲突管理过程中个体特征与团队特征间的交互效应。基于个人-团队匹配理论, 本研究探讨了个体层面宜人性与团队层面宜人性异质性对团队中个体冲突(关系冲突、任务冲突)和工作绩效间关系的影响。基于来自64个银行服务团队(包含339名下属和64名主管)的多来源、多时点纵向数据, 本研究所得结果显示：(1)关系冲突显著负向影响工作绩效, 任务冲突对工作绩效的影响不显著。(2)个体宜人性能够显著减弱关系冲突对工作绩效的负面影响, 而增强任务冲突对工作绩效的正向影响。(3)关系/任务冲突、个体宜人性和团队宜人性异质性间存在着三重交互效应, 共同影响工作绩效。具体而言, 当团队宜人性异质性水平较低时, 个体宜人性对关系/任务冲突与工作绩效间关系的调节作用更加显著。
