Five three-man teams were conditioned to a multiple DRL-DRH schedule during five daily sessions of 3 hr each. The teams were conditioned on the basis of their cumulative response rate regardless of the contributions of individual members. Two individually conditioned Ss were run under a similar schedule for comparison. Although all teams demonstrated some differentiation of response rate under the two legs of the schedule, this difference was not achieved as rapidly, nor was it as stable, as the differentiation in rates achieved in individually conditioned Ss. Team members displayed a variety of response rates as a result of collective team conditioning. Often, individual response rates interfered with obtainment of team reinforcement. The individual team members displayed little SD control in comparison with the individually conditioned Ss. In general the results suggest that collective reinforcement is highly inefficient in comparison with procedures employing individual feedback. 相似文献

Criminal justice, mental health, and social service professionals face a myriad of role expectations in working with prisoners with mental illness to facilitate community re-entry. These expectations include those related to law enforcement, social welfare, and administrative efficiency. The challenge for front line workers and the multiple systems that employ them is to integrate all these expectations effectively on behalf of the individual as well as the community. Current models of re-entry for individuals leaving prison with mental illness focus on the management and interaction of service systems. This paper presents a model of prisoner re-entry that incorporates a larger social context, illustrating dynamics related to both individuals with mental illness leaving prison and their interaction with the community setting. This model was generated through an interdisciplinary team effort. It was refined through a focus group process that included advocates, community members and other informants from mental health and criminal justice systems in five states. The model is designed to generate new questions for research that address both individual and community level issues. 相似文献

Misbehaviors occur at a high rate during the toddler years, and parents use a variety of methods to control these behaviors. The present investigation compared the effectiveness of two commonly used strategies, distraction and reprimands. Twenty mothers and their 17- to 39-month-old children were observed in a laboratory setting in which mothers used either distraction then reprimands or reprimands followed by distraction in response to their children's transgressions. When reprimands were used as the initial strategy, they were significantly more effective than distraction in controlling children's transgressions. Distraction was effective in maintaining low rates of transgression when preceded by a period of reprimands. However, when reprimands were instituted following a period of distraction, children's rates of negative affect increased significantly. Implications for the etiology and management of child behavior problems are discussed. 相似文献

An experiment was run to determine if androgynous people have transcended traditional sex roles or merely incorporated both sex roles into their repertoire. Masculine sex-typed, feminine sex-typed, and androgynous people listed as many masculine and feminine stereotypes as they could think of in a time-limited task. Highly sex-typed individuals showed more awareness of their own sex's attributes than the other sex's stereotypes. Androgynous people showed greater awareness of both sexes' attributes as compared with sex-typed people, indicating support for the incorporation hypothesis rather than the transcendance hypothesis. However, the stereotypes androgynous people listed were somewhat less evaluative in tone compared with those of sex-typed people, Overall, subjects listed more stereotypes of females than males, and female stereotypes were more negative than male stereotypes. 相似文献

The dynamics model, which is based on L. Talmy's (1988) theory of force dynamics, characterizes causation as a pattern of forces and a position vector. In contrast to counterfactual and probabilistic models, the dynamics model naturally distinguishes between different cause-related concepts and explains the induction of causal relationships from single observations. Support for the model is provided in experiments in which participants categorized 3-D animations of realistically rendered objects with trajectories that were wholly determined by the force vectors entered into a physics simulator. Experiments 1-3 showed that causal judgments are based on several forces, not just one. Experiment 4 demonstrated that people compute the resultant of forces using a qualitative decision rule. Experiments 5 and 6 showed that a dynamics approach extends to the representation of social causation. Implications for the relationship between causation and time are discussed. 相似文献
