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

Objective: Physical activity is a key factor for healthy ageing, yet many older people lead a sedentary lifestyle. Traditional physical activity interventions do not consider the specific needs and views of older adults. As views on ageing are known to be related to health behaviours, the current study evaluates the effectiveness of prompting positive views on ageing within a physical activity intervention.Design: Randomised controlled trial with three groups aged 65+: Intervention for physical activity with ‘views-on-ageing’-component (n?=?101; IGVoA), and without ‘views-on-ageing’-component (n?=?30; IG), and active control intervention for volunteering (n?=?103; CG).Main outcome measures: Attitudes towards older adults and physical activity were assessed five weeks before intervention, two weeks, six weeks and 8.5?months after the intervention.Results: Compared to the IG and CG, positive attitudes towards older adults increased in the IGVoA after the intervention. For IGVoA, the indirect intervention effect on change in activity via change in attitudes towards older adults was reliable.Conclusion: A ‘views-on-ageing’-component within a physical activity intervention affects change in physical activity via change in views on ageing. Views on ageing are a promising intervention technique to be incorporated into future physical activity interventions for older adults. 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

In this article, the authors propose and test an interactionist model of personality functioning. The model maintains that many traits function in a threshold-like manner, such that less situational strength is needed to evoke a trait-relevant response in people who are high on the trait than in those who are low on the trait. Because of these different sensitivities, people who are high on a trait are more reactive to moderate provocation than are those who are low on a trait, but the opposite is true when strong provocation is compared to moderate provocation. Three studies are reported showing how the model can be used to understand the nature of aggression. 相似文献

Two experiments investigated how self-esteem guides people's emotional responses to changing evaluative feedback. In both experiments, participants received an initial evaluation (either positive or negative) followed by a second evaluation (either positive or negative). Emotional reactions to the second evaluation were then assessed. High self-esteem participants found feedback that was consistently negative to be most distressing, whereas low self-esteem participants were most disturbed by feedback that changed from positive to negative. The theoretical and practical implications of the findings are discussed. 相似文献
