The 12-item Claremont Purpose Scale (CPS) was designed for use with adolescents, and it gauges all three dimensions of the purpose construct, including goal-directedness, personal meaning, and a beyond-the-self orientation. Repeated administration reveals promising psychometric properties. For instance, the CPS demonstrates excellent internal consistency (α = .916?.935) and convergent validity. In exploratory and confirmatory factor analyses, items fell onto the three dimensions, and the measure accounted for variance on indicators of a beyond-the-self orientation above and beyond the PIL. In addition to discussing the measure’s creation and validation, suggested uses of the CPS are also addressed.  相似文献

To date over two billion dollars have been invested in the John F. Chafee Foster Care Independence Program (CFCIP) to help youth who are transitioning out of foster care to achieve self-sufficiency through an array of independent living services. Although states are required to report CFCIP service provision to the National Youth in Transition Database (NYTD), the degree of heterogeneity of the aging out population from the service receipt perspective and state implementation is unknown. The CFCIP calls for a deeper understanding of the underlying patterns of services receipt to prepare for youth’s successful transition to adulthood. Based on the population of 68,057 first-time youth who received CFCIP services in FY2011-FY2013 from the NYTD, we used multi-level latent class analysis (MLCA) to identify underlying combinations of service receipt that may be influenced by youth-level and state-level characteristics. We identified the most preferred model based on interpretability, fit statistics, and split-half replication. The optimal model was a three-class, MLCA solution characterized by a high-service receipt profile, an independent living assessment and academic support receipt profile, and a limited service receipt profile. Among male and female youth, age, education level, and whether states serve youth aged 18 or above were significant characteristics associated with LCA profile membership. States could benefit from understanding existing service receipt patterns and gaps to optimize decisions on service delivery in order to meet youth needs and to identify specific services that may prepare youth aging out of foster care towards positive outcomes.  相似文献

Interventions aimed at enhancing mental health are increasingly centered around promoting community attachment and support. However, few have examined and tested the specific ecological factors that give rise to these key community processes. Drawing from insights from the ecological network perspective, we tested whether spatial and social overlap in routine activity settings (e.g., work, school, childcare) with fellow ethnic community members is associated with individuals’ attachment to their ethnic communities and access to social resources embedded in their communities. Data on routine activity locations drawn from the Refugee Well‐Being Project (based in a city in the Southwestern United States) were used to reconstruct the ecological networks of recently resettled refugee communities, which were two‐mode networks that comprise individuals and their routine activity locations. Results indicated that respondents’ community attachment and support increased with their ecological network extensity—which taps the extent to which respondents share routine activity locations with other community members. Our study highlights a key ecological process that potentially enhances individuals’ ethnic community attachment that extends beyond residential neighborhoods.  相似文献

An intrinsic part of seeing objects is seeing how similar or different they are relative to one another. This experience requires that objects be mentally represented in a common format over which such comparisons can be carried out. What is that representational format? Objects could be compared in terms of their superficial features (e.g., degree of pixel-by-pixel overlap), but a more intriguing possibility is that they are compared on the basis of a deeper structure. One especially promising candidate that has enjoyed success in the computer vision literature is the shape skeleton—a geometric transformation that represents objects according to their inferred underlying organization. Despite several hints that shape skeletons are computed in human vision, it remains unclear how much they actually matter for subsequent performance. Here, we explore the possibility that shape skeletons help mediate the ability to extract visual similarity. Observers completed a same/different task in which two shapes could vary either in their skeletal structure (without changing superficial features such as size, orientation, and internal angular separation) or in large surface-level ways (without changing overall skeletal organization). Discrimination was better for skeletally dissimilar shapes: observers had difficulty appreciating even surprisingly large differences when those differences did not reorganize the underlying skeletons. This pattern also generalized beyond line drawings to 3-D volumes whose skeletons were less readily inferable from the shapes’ visible contours. These results show how shape skeletons may influence the perception of similarity—and more generally, how they have important consequences for downstream visual processing.

A social partner’s emotions communicate important information about their motives and intentions. However, people may discount emotional information that they believe their partner has regulated with the strategic intention of exerting social influence. Across two studies, we investigated interpersonal effects of communicated guilt and perceived strategic regulation in trust games. Results showed that communicated guilt (but not interest) mitigated negative effects of trust violations on interpersonal judgements and behaviour. Further, perceived strategic regulation reduced guilt’s positive effects. These findings suggest that people take emotion-regulation motives into account when responding to emotion communication.  相似文献

In preparing for an aging global population, older adults’ well-being has become an urgent priority across the world. Counseling psychologists have also called upon the field for more empirical attention on older adults. Yet, a review of the literature revealed that older adults were represented in less than 2% of all the articles in the Journal of Counseling Psychology (JCP) and The Counseling Psychologist (TCP) from 1991 to 2000. The current study presents a follow-up review of older adult research in counseling psychology literature between 2001 and 2015 in the following mainstream journals: Counselling Psychology Quarterly (CPQ), JCP, and TCQ. Results suggest a decline in the past 15 years, with less than 1% of the total articles in JCP, TCP, and CPQ devoted to older adults. Most of the studies employed cross-sectional survey research design to examine predictors of mental health. A number of studies focused on culture-specific experiences of diverse older adults. Implications and suggestions for future research on older adult issues are discussed in relation to the principles and interests rooted in the field of counseling psychology.  相似文献

Why do utterances of counterfactual conditionals typically, but not universally, convey the message that their antecedents are false? I demonstrate that two common theoretical commitments–commitment to the existence of scalar implicature and of informative presupposition—can be supplemented with an independently motivated theory of the presuppositions of competing conditional alternatives to jointly predict this information when and only when it appears. The view works best if indicative and counterfactual conditionals have a closely related semantics, so I conclude by undermining two familiar arguments for a nonunified semantics of indicative and counterfactual conditionals.  相似文献

Enormous harms, such as climate change, often occur as the result of large numbers of individuals acting separately. In collective action problems, an individual has so little chance of making a difference to these harms that changing their behavior has insignificant expected utility. Even so, it is intuitive that individuals in many collective action problems should not be parts of groups that cause these great harms. This paper gives an account of when we do and do not have obligations to change our behavior in collective action problems. It also addresses a question insufficiently explored in the literature on this topic: when obligations arising out of collective action problems conflict with other obligations, what should we do? The paper explains how to adjudicate conflicts involving two collective action problems and conflicts involving collective action problems and other sorts of obligations.  相似文献
