Research has shown that behavior contracts, a form of contingency management, can promote a wide range of behavior changes for individuals in varied populations; however, relatively few studies have been conducted in nonacademic settings. In the context of two service projects, we evaluated the extent to which behavior contracts improved problem behavior for 11 children and adolescents in residential treatment facilities and foster homes using nonconcurrent multiple baseline across participants’ designs with three or more tiers and supplemental statistical analysis for each tier. Practitioners in each setting implemented individualized behavior contracts for 5 to 59 weeks. Results show that behavior improved substantially for six participants but was relatively unchanged for the other five participants. We discuss the limitations of this clinically driven study, as well as clinical implications of our mixed findings.  相似文献

The purpose of this study was to assess and compare the relative contribution of skin tone and symmetry on judgment of attractiveness regarding female faces. Two hundred and fifteen Mozambican adults were presented with a set of faces, and instructed to rate their degree of attractiveness along a continuous scale. Chi-square, factorial weight analyses and ANOVA were used to analyze the data. Face skin tone had a significant impact on the participants' attractiveness judgment of target faces. However, the target face skin tone contribution to the participants' attractiveness judgment (5% of the total variance) was much weaker than the contribution of the target face symmetry (85% of the total variance). These results imply that skin bleaching, common among Black people across sub-Saharan African countries, is not only dangerous to the health of those who practice it, but it is unlikely to make them appear much more attractive.  相似文献

Many scientists have argued forcefully for the pointlessness of nature, something that challenges any doctrine of Creation. However, apparent design and comprehensibility are also to be found in nature; it is ambivalent. This trait is nowhere more evident than in the natural inclinations that lead to concupiscence and the "seven deadly sins" in human beings. These inclinations are dealt with as pertaining to the "pre-fallen" condition of nature and human beings. As a framework to make sense of the goodness of creation in this context, Paul Tillich's notion of the "vital trends of nature" is called to the fore. Being at the intersection of a philosophy of religion and a philosophy of nature, this notion hints at the goodness of Creation in fragment and anticipation.  相似文献

This qualitative article examines views of students at the University of Ghana on the topic of virginity with specific focus on its gendered meaning and relative significance in modern times. One-on-one interviews were conducted with 30 purposively selected research participants with the aid of an interview guide. Through thematic analysis, the results indicated that the majority of the respondents believed that virginity has been stereotyped on women due to the patriarchal cultural systems and the significance of the hymen. It was also found that the participants constructed their perspectives on virginity based on religious obligations, repercussions of sex and sexual health. Reactions to virginity loss also differed on gender. Implications of this study include the need for public conscientization on the repercussions of sexual activities, direct parent–child discourse about sex and the need for counseling centers within social institutions to offer advice and support to the youth on the subject matter.  相似文献

This article discusses the dissemination of a process of youth-led participatory research in urban secondary schools within the Interactive Systems Framework for Dissemination and Implementation (ISF) developed in collaboration with the CDC and its university partners (Wandersman et al. American Journal of Community Psychology, 41(3-4) 2008). The focus here is on the development of the Prevention Support System with respect to general and innovation-specific capacity building. The specific process under study involves youth-led needs assessment and research to inform the planning of prevention programs and policies to address students' health and developmental needs. The article first briefly describes the youth-led research process, its potential benefits, and a case example in two urban secondary schools. It then describes challenges and responses in providing support for the diffusion of this model in 6 secondary schools. The settings are urban public schools with a majority of students of color from diverse ethnic groups: Asian-American, Latino, and African-American. This project constitutes a collaborative partnership with a university school of public health and community-based organizations (CBOs) to build capacity for long-term, sustainable implementation of this innovative process within the local school system. The perspectives of the university-based researcher and the CBO partners on the development and effectiveness of the Prevention Support System are presented.  相似文献

Rats take correct novel routes and shortcuts in an enclosed maze   总被引:1,自引:0,他引:1  
In 3 experiments, rats were allowed to travel selected routes along the internal alleys of a cross-maze that led from one distinctive end box to another. The maze and procedures used were designed to control the rats' ability to use intrinsic and extrinsic cues to their location in the maze; thus, only the internal geometry of the maze could be learned and used to travel between one end box and another. After an initial exploration phase, rats were given novel routes and shortcut tests that involved peripheral alleys not before traveled. Rats chose the correct novel path or shortcut significantly above chance on some tests in Experiments 1 and 2 and significantly better than a control group in Experiment 3. The findings suggest that rats were able to compute novel routes and shortcuts within the maze on the basis of limited experience with the internal geometry of the maze.  相似文献

We used a numerical bisection procedure to examine preschool children's sensitivity to the numerical attributes of stimuli. In Experiment 1 children performed two tasks. In the Cups Task they earned coins for choosing a green cup after two drumbeats and a blue cup after eight drumbeats. In the Gloves Task they earned coins for raising a red glove on their left hand after two drumbeats and a yellow glove on their right hand after eight drumbeats. Then in each task a psychometric function was obtained by presenting intermediate numerosities and recording the percentage of trials in which children chose the "many" option. In Experiment 2 children's performance in a '2 vs. 8' discrimination was compared with their performance in a "4 vs. 16" discrimination. Results showed that the individual psychometric functions were of two types, one in which the percentage of "many" choices increased gradually with stimulus numerosity and another in which it increased abruptly, in a step-like manner. Although the average point of subjective equality was close to the geometric mean of the anchor numerosities and the average functions for "2 vs. 8" and "4 vs. 16" superimposed when plotted on a common scale (the scalar property), the individual data were highly variable both across tasks (Cups and Gloves) and numerosity ranges ('2 vs. 8' and '4 vs. 16'). It is suggested that between- and within-subjects variability in the psychometric function is related to children's verbalizations about the sample stimulus.  相似文献

This study examined the needs that young people in Guadalajara, in the state of Jalisco, Mexico, expressed in phone calls to a research unit of the Mexican Social Security Institute. Three hundred forty-five calls, from individuals 11 to 24 years old who phoned from June 1995 to November 1998, were analyzed. Two hundred ninety-four of the callers were female and 51 were male. Greater percentages of females than males called to ask about sexuality and family problems. Males more than females asked about reproductive health (particularly pregnancy) and mental health. There were significant differences by gender and age, differences that were not detected in health service statistics. The findings have implications for decision makers and health and education service providers. They point to the need for programs that will reinforce young people's good health practices and help them avoid risky behaviors.  相似文献

This paper presents an introduction to theoretically informed qualitative psychotherapy research (QPR). Although QPR researchers have traditionally remained silent on theory, we suggest this has resulted in an implicit and unacknowledged use of theory. We argue instead for a clear articulation of qualitative researchers' theory and outline how theory can be incorporated to inform the entire qualitative research process. This approach assumes the research problem is embedded in a clearly defined and articulated theoretical framework, which also informs data collection and data analysis. We outline how researchers can use explicit theoretical frameworks to inform research question formulation, data collection and data analysis and illustrate this with specific applications of the method in practice. We believe that starting from a declared theoretical framework sets up a dialogue between the research problem, the type of data required and their meaningful analysis and interpretation. This aims not only to achieve greater depth in the final product of research, but also to enhance its utility in terms of practice; it contributes to building, altering and differentiating theory; and it allows for greater transparency by openly articulating the theoretical framework that scaffolds the entirety of the research process.  相似文献
