OBJECTIVE: The purpose of this study is to examine processing of facial emotions in a sample of maltreated children showing high rates of post-traumatic stress disorder (PTSD). Maltreatment during childhood has been associated independently with both atypical processing of emotion and the development of PTSD. However, research has provided little evidence indicating how high rates of PTSD might relate to maltreated children's processing of emotions. METHOD: Participants' reaction time and labeling of emotions were measured using a morphed facial emotion identification task. Participants included a diverse sample of maltreated children with and without PTSD and controls ranging in age from 8 to 15 years. Maltreated children had been removed from their homes and placed in state custody following experiences of maltreatment. Diagnoses of PTSD and other disorders were determined through combination of parent, child, and teacher reports. RESULTS: Maltreated children displayed faster reaction times than controls when labeling emotional facial expressions, and this result was most pronounced for fearful faces. Relative to children who were not maltreated, maltreated children both with and without PTSD showed enhanced response times when identifying fearful faces. There was no group difference in labeling of emotions when identifying different facial emotions. CONCLUSIONS: Maltreated children show heightened ability to identify fearful faces, evidenced by faster reaction times relative to controls. This association between maltreatment and atypical processing of emotion is independent of PTSD diagnosis.  相似文献

In this paper we consider discourses of friendship and belonging mobilised by girls who are not part of the dominant ‘cool’ group in one English primary school. We explore how, by investing in alternative and, at times, resistant, discourses of ‘being nice’ and ‘being normal’ these ‘non-cool’ girls were able to avoid some of the struggles for dominance and related bullying and exclusion found by us and other researchers to be a feature of ‘cool girls’ groupings. We argue that there are multiple dynamics in girls' lives in which being ‘cool’ is only sometimes a dominant concern. There are some children for whom explicitly positioning themselves outside of the ‘cool’ group is both resistant and protective, providing a counter-discourse to the dominance of ‘coolness’. In this paper, which is based on observational and interview data in one school in the south of England, we focus on two main groupings of intermediate and lower status girls, as well as on one ‘wannabe’ ‘cool girl’. While belonging to a lower status group can bring disadvantages for the girls we studied, there were also benefits.  相似文献

In this article, we investigate how the national imperative to increase opportunities for young women of color in science, technology, engineering, and mathematics (STEM) and to broaden their participation was taken up locally at two high schools in one school district. Using ethnographic and longitudinal data, we focus on four young women of color (two at each school) as they negotiated STEM-related identities in the discursive and practice contexts of their lives at school. Using Holland and Lave’s concept of history in person, we view the young women as fighting for particular versions of a future self while entangled in discursive and social relations that threatened to position them differently than they wished to be. We find that their fight for future selves was not—for them—with the national narrative about women of color in STEM but with local school narratives that negatively positioned students of color more broadly and remained silent on issues of gender, the intersection of gender and race, and the implications for STEM. High school success in STEM came as a hopeful but potentially fragile byproduct of struggles to differentiate themselves from people like them (other Blacks, Latinas, the poor). Implications of these findings are discussed.  相似文献

Modesty may be a significant variable impacting breast- feeding outcomes in western cultures, yet this term has received minimal attention in the breastfeeding literature. An analysis of the concept of modesty was conducted to gain greater understanding of the potential impact of modesty on breastfeeding outcomes. Various uses of the term modesty and particularly modesty in the context of breastfeeding are discussed in this paper. The defining attributes of breastfeeding modesty are identified and examples are provided. Implications for research and clinical practice are suggested.  相似文献

This study examined the effects of rewards on the ideational fluency of 75 preschool children. Assigned to a reward or nonreward condition, the children were administered two ideational fluency tasks, Unusual Uses and Pattern Meanings. Analyses revealed a significant main effect for reward on the ideational fluency components of originality, total fluency, and flexibility. In all cases the rewarded subjects scored lower than the nonrewarded group. These findings support the growing body of evidence that rewards are detrimental to creative functioning.  相似文献

Many short-duration science outreach interventions have important societal goals of raising science literacy and increasing the size and diversity of the science workforce. Yet, these long-term outcomes are inherently challenging to evaluate. We present findings from a qualitative research study of an inquiry-based, life science outreach program to K-12 classrooms that is typical in design and excellent in execution. By considering this program as a best case of a common outreach model, the "scientist in the classroom," the study examines what benefits may be realized for each participant group and how they are achieved. We find that K-12 students are engaged in authentic, hands-on activities that generate interest in science and new views of science and scientists. Teachers learn new science content and new ways to teach it, and value collegial support of their professional work. Graduate student scientists, who are the program presenters, gain teaching and other skills, greater understanding of education and diversity issues, confidence and intrinsic satisfaction, and career benefits. A few negative outcomes also are described. Program elements that lead to these benefits are identified both from the research findings and from insights of the program developer on program design and implementation choices.  相似文献

This meta-analysis investigated the maturation-related pattern of adaptations to resistance training in boy athletes. We included studies examining the effects of 4–16-week resistance training programmes in healthy boy athletes aged 10–18 years. Pooled estimates of effect size for change in strength across all studies (n = 19) were calculated using the inverse–variance random effects model for meta-analyses. Estimates were also calculated for groups based on likely biological maturity status (“before”, “during” and “after” peak height velocity). Using the standardised mean difference, resistance training increased strength across all groups (effect size = 0.98, [CI: 0.70–1.27]). Strength gains were larger during (1.11 [0.67–1.54]) and after (1.01 [0.56–1.46]) peak height velocity than before (0.5 [?0.06–1.07]). Adaptations to resistance training are greater in adolescent boys during or after peak height velocity. These findings should help coaches to optimise the timing of training programmes that are designed to improve strength in boy athletes.  相似文献

The past decade has witnessed increased interest in the visual search behaviour of athletes. Little is known, however, about the relationship between anxiety and eye movements in sport performers or about the extent to which athletes' planned and actual visual search strategies correspond. To address these issues, we conducted two studies. In Study 1, eight expert female gymnasts were presented with three digital slides of a model performing a skill that is known to be anxiety-provoking in this sport--namely, the 'back flip' on the beam. By varying the height of the beam and the presence or absence of safety mats, the slides differed in the amount of anxiety that they elicited vicariously in the viewer. In the study, the gymnasts were asked to imagine themselves in the position of the depicted model and to describe the anxiety that they felt. As they viewed the slides, their eye movements were recorded. As predicted, anxiety was associated with an increase in the number of fixations to peripheral areas. In addition, the more 'threatening' slides elicited significantly more fixations than the less feared images. In Study 2, the plans of 15 equestrian performers (5 expert, 5 intermediate and 5 novice) were elicited as they engaged in a virtual 'walk' around a computerized show-jumping course. Contrary to expectations, the congruence between intended and actual search behaviour was not significantly greater for expert riders than for the less skilled groups. Also, the fact that the top riders allocated more fixations to slides than the less skilled performers challenged the prediction that expertise would be associated with economy of visual search. Finally, as expected, the expert riders were significantly less dependent on the overall 'course plan' than the intermediate and novice equestrian performers when inspecting the fences.  相似文献
