Deficient self-regulation plays a key role in the etiology of early onset disruptive behavior disorders and signals risk for chronic psychopathology. However, to date, there has been no research comparing preschool children with and without high levels of disruptive behavior using Event Related Potentials (ERPs) associated with specific self-regulation sub-processes. We examined 15 preschool children with high levels of disruptive behavior (35 % female) and 20 peers with low disruptive behavior (50 % female) who completed a Go/No-go task that provided emotionally valenced feedback. We tested whether 4 ERP components: the Error Related Negativity, the Error Positivity, the Feedback Related Negativity, and the No-go N2, differed in preschool children with and without high levels of disruptive behavior. Preschoolers with high levels of disruptive behavior showed less differentiation between the Error Positivity and corresponding waveforms following correct responses at posterior sites. Preschoolers with high and low disruptive behavior also showed differences in Go/No-go N2 waveform amplitudes across electrodes. These findings suggest that preschool children with high levels of disruptive behavior may show abnormal brain activity during certain self-regulation sub-processes, informing potential advances in conceptualizing and treating early disruptive behavior.  相似文献

Research examining wildlife law enforcement has steadily grown within recent years. Few studies, however, are based outside of the United States. Furthermore, studies that have examined wildlife law enforcement in other settings, including African countries, have primarily focused on quantifying the effectiveness of patrol activities, but little is known about actual patrol activities. Based on interviews and participant observation, this research attempts to contribute to both the criminal justice and conservation science literature by providing an in-depth qualitative investigation of law enforcement rangers’ roles, responsibilities, and patrol operations in a protected area in Uganda.  相似文献

The present study is a two-wave longitudinal study of the concurrent and prospective associations between patterns of same- and other-gender liking and well-being in a sample of 403 fifth and sixth-grade girls and boys from Montréal Québec, Canada that was used to examine Sandra Bem’s perspective that androgyny is related to well-being. In our study androgyny was operationally defined as (a) the combination of liking for same- and other-gender peers and (b) the combination of being liked by same- and other-gender peers. Well-being was indexed with a measure of the self-concept. Findings drawn from analyses conducted with structural equation modeling showed that androgynous liking was an antecedent and a consequence of well-being. Specifically (a) Time 1 (T1) well-being was a predictor of how much girls and boys liked same-gender and other-gender peers at Time 2 (T2) whereas T2 well-being was predicted by how much girls and boys liked same- and other-gender peers at T1 and (b) T2 well-being was predicted by how much girls and boys were liked by same-gender and other-gender peers. These findings are discussed according to the dynamics of experiences with peers from one’s own gender and the other-gender.  相似文献

In this introduction to the Special Issue on the use of sports data to inform research and practice in organizations, we first outline the state of research in this flourishing area to provide the need for this Special Issue. We note a similarity in the study of organizations and the study of sports and, in turn, how studies of sports can readily be compared to and applied to the study and practice of work in organizations. Next, we describe each of the six articles in this Special Issue, particularly noting that the articles sampled data from a variety of sporting domains, ranging from the National Football League to Olympic ice hockey. Topics of the studies included travel stress on team performance; pay standing and task performance; job hopping, organizational change, and performance of new employees; team work experience and performance; the effect of leadership transitions and changes to performance and human capital quality; and the effects of star performers and core team members. We then outline how these studies fit with the call for this Special Issue and provide common themes, such as methodological sophistication and novel analyses and the opportunity for sports data to provide both academic and practitioner audiences an awareness of evidence-based approaches to studies of work. We end this introductory article by providing some challenges in using sports data to enhance the study of organizations and possible areas for future research.  相似文献

In this discussion of Bob Bartlett’s compelling paper “Time-Soaked,” I shift attention away from the vivid account of the interpersonal dynamics between Bartlett and his patient to describe the perspectives offered by theories of social memory and transgenerational haunting. I attempt to speak for and convey the voices and vulnerabilities of previous generations that I argue—if heard within the analytic dyad—can further inform and deepen the therapeutic endeavors undertaken by Bartlett and his patient.  相似文献

DeLeon and Iwata (1996) described the difficulties in applying the percentage approached scoring method to the multiple stimulus without replacement (MSWO) preference assessment relative to its application in the paired stimulus assessment. This scoring method may result in highly preferred items being misidentified as moderate or low preference. In the present study, the results of 57 MSWO assessments were scored using both the percentage approach method and a point weighting method. More items were identified as highly preferred with the point weighting method. Reinforcer assessments were conducted on a subset of stimuli judged to be high preference using the point weighting method but moderately or non‐preferred when scored with the percentage approached method; all stimuli functioned as reinforcers.
