Zalocusky et al. (Nature 531:642–646, 2016) recently showed that activity in D2R+ cells in the nucleus accumbens is associated with loss sensitivity to prior outcomes and reduced subsequent risky choice, and that optogenetic stimulation of these cells decreased risky choices in risk-prone rats. While their findings are important for understanding trait-level risk-taking, future research should aim to examine the neuronal mechanisms of a broader range of facets of gain and loss processing with respect to different potential reference points.  相似文献

In 2014–2015 and 2015–2016, a metropolitan school system in the southern United States embarked on a unique mission to improve the quality of its public prekindergarten programs through a partnership with a group of developmental researchers in an iterative, data‐based venture. Data on 407 children in Year 1 and 433 in Year 2 (who were enrolled in 26 classrooms and extensively observed) are presented from the first 2 years of the ongoing partnership. All children were 4 years of age. Variability in classroom practices, measured empirically, and variability in child outcomes provided the means to examine the relations between children's gains in academic and social‐emotional areas and major areas of classroom practices. Lessons learned, the eight identified significant practices, implications, and next steps in the partnership are addressed.  相似文献

Research Findings: In addition to being a regulatory strategy, children’s private speech may enhance or interfere with their effortful control used to regulate emotion. The goal of the current study was to investigate whether children’s private speech during a selective attention task moderated the relations of their effortful control to their anger and sadness. The private speech of 156 preschoolers (age in months: M = 52.10, SD = 9.24, min = 36.20, max = 69.50) was transcribed and coded during a selective attention task. Effortful control was observed and reported by parents. Anger and sadness were reported by parents and observed in a frustration task. Children who used more inaudible muttering had higher levels of sadness. Effortful control interacted with private speech to explain anger. The negative relation of effortful control to anger was significant for children who used low and moderate but not high levels of task-irrelevant private speech. Practice or Policy: The presence of private speech, although it may support regulatory abilities within a task, may be an additional form of evaluation that might help teachers and caregivers decide how best to support children’s learning. These findings suggest that private speech can be used as an indicator of how well children use other regulatory abilities, such as effortful control.  相似文献

Given the high prevalence of HIV/AIDS in Kenya, more Kenyans now find themselves in the role of informal caregiver for a family member or multiple family members living with HIV/AIDS. However, there exists little research on how these individuals cope. The present study explores coping responses among caregivers for family members living with HIV/AIDS in Kenya. An exploratory factor analysis of the Brief COPE yielded five factors, with strong loadings on Emotional Support and Instrumental Support. Implications for using the Brief COPE in research and clinical practice among Kenyans are discussed.  相似文献

Placing Facebook     
Facebook is challenging professional journalism. These challenges were evident in three incidents from 2016: the allegation that Facebook privileged progressive-leaning news on its trending feature; Facebook’s removal of the Pulitzer Prize-winning “Napalm Girl” photo from the pages of prominent users; and the proliferation of “fake news” during the US presidential election. Using theoretical concepts from the field of boundary work, this paper examines how The Guardian, The New York Times, Columbia Journalism Review and Poynter editorialized Facebook’s role in these three incidents to discursively construct the boundary between the value of professional journalism to democracy and Facebook’s ascendant role in facilitating essential democratic functions. Findings reveal that these publications attempted to define Facebook as a news organization (i.e., include it within the boundaries of journalism) so that they could then criticize the company for not following duties traditionally incumbent upon news organizations (i.e., place it outside the boundaries of journalism). This paper advances scholarship that focuses on both inward and outward conceptions of boundary work, further explores the complex challenge of defining who a journalist is in the face of rapidly changing technological norms, and advances scholarship in the field of media ethics that positions ethical analysis at the institutional level.  相似文献

Although the effectiveness of inoculation as a strategy for promoting resistance to attitude change is fairly well established, the potential of inoculation messages to offer cross-protection for related, but untreated, attitudes warrants additional attention from scholars. The reported study tested the “blanket of protection” conferred by inoculation. Participants (N = 118) were randomly assigned to read an inoculation message addressing a target topic and subsequently had their attitudes toward three related, but untreated, topics attacked. The results offer some evidence that inoculation messages can confer cross-protection for related attitudes. Participants in the inoculation condition reported greater perceptions of threat, greater counterarguing, and less attitude change in response to attacks than participants in the control condition for two of the three untreated topics. Counterarguing in response to attacks on untreated attitudes appears to be primarily responsible for cross-protection.  相似文献

Reference departments track patron interactions to illustrate the type and number of services provided as well as to tailor librarians’ time and expertise to the interest and needs of their patrons. Until 2010 the Reference, Education, and Community Engagement Department at the Calder Memorial Library tracked statistics using a complicated system of paper tic sheets and two Excel? spreadsheets. After considering different electronic systems, the department decided to employ an electronic form created with SurveyMonkey? to track patron interactions. After the system had been in place for three months, the authors administered a satisfaction and use survey to collect faculty and staff feedback on the new system. Seven months later the authors undertook usability testing to collect further evaluative data on the electronic form. The patron interaction form continues to be used to collect statistics, provide data for annual reviews, and recognize the contributions of all faculty and staff at the library.  相似文献
