Children and adolescents (N = 153, ages 8–14 years, Mage = 11.46 years) predicted and evaluated peer exclusion in interwealth (high-wealth and low-wealth) and interracial (African American and European American) contexts. With age, participants increasingly expected high-wealth groups to be more exclusive than low-wealth groups, regardless of their depicted race. Furthermore, children evaluated interwealth exclusion less negatively than interracial exclusion, and children who identified as higher in wealth evaluated interwealth exclusion less negatively than did children who identified as lower in wealth. Children cited explicit negative stereotypes about high-wealth groups in their justifications, while rarely citing stereotypes about low-wealth groups or racial groups. Results revealed that both race and wealth are important factors that children consider when evaluating peer exclusion. 相似文献

This study takes an ecological approach to examine how children with developmental language disorder (DLD) interact with their classmates within early childhood special education (ECSE) inclusive classrooms. Participants were 124 children with DLD, 56 children with other disabilities, and 247 typically developing children (Mage = 52.42 months, SD = 6.27) from 56 ECSE inclusive classrooms. Results of social network analysis showed that children with DLD had significantly smaller peer social networks and were more likely to be isolated. Children tended to interact with peers with the same DLD status. These effects of children's DLD status were above and beyond the effects of children's social pragmatics skills. 相似文献

Gender-nonconforming (GN) children are often perceived less positively, which may harm their well-being. We examined the development of such perceptions and an intervention to modify them. Chinese children’s appraisals were assessed using multiple measures (verbal responses, sharing, and rank order task) after viewing vignettes of gender-conforming (GC) and GN hypothetical peers. In Study 1, children (N = 210; 4-, 5-, 8-, and 9-year-olds) were less positive toward GN than GC peers, especially if they were older or if the peers were boys. In Study 2 (N = 211, 8- and 9-year-olds), showing children exemplars of GN peers who displayed positive and GC characteristics subsequently reduced bias against gender nonconformity. These findings inform strategies aimed at reducing bias against gender nonconformity. 相似文献

Contextual influences on private speech were examined in two preschools differing in the learning environments they provide for children. Observations of 3- to 5-year-olds were made during free-choice periods in a Montessori and a traditional (play-oriented) program. Consistent with Vygotsky's theory that make-believe play serves as a vital context for the development of self-regulation, the incidence of private speech was much higher during open-ended activities, especially fantasy play, that require children to determine the goal of the task, than during closed-ended tasks with predetermined goals. In line with previous research, the more direct involvement, or external regulation, teachers displayed, the lower the rate of children's private speech. In addition, transitions (as opposed to involvement in activities) were linked to reduced private speech, whereas engagement with peers, in the form of associative play, predicted greater self-directed language. Diminished make-believe play, greater teacher direct involvement, and heightened time spent in transitions largely accounted for the lower incidence of private speech in the Montessori compared with the traditional preschool. Contextual factors also contributed to a drop in private speech at age 5. Implications for fostering children's verbal self-regulation during early childhood are considered. 相似文献

Given the lack of relevant data, the aim of this study was to examine femur cortical and trabecular bone in female and male professional ballet dancers. 40 professional ballet dancers and 40 sex- and age-matched non-exercising controls volunteered. Femoral bone density was scanned by dual-energy X-ray absorptiometry (DXA) scan. A 3D-DXA software was used to analyse trabecular and cortical bone. Anthropometry, maturation (Tanner staging), menstrual parameters (age at menarche and primary amenorrhea), energy availability and nutritional analysis (3-day record) were also assessed.Compared to non-exercising participants, dancers exhibited significantly higher volumetric density for integral, cortical and trabecular bone, and thicker cortex at the femur. Ballet dancers demonstrated lower body weight compared to controls (p < 0.01). Female dancers had their menarche later than controls, and the prevalence of primary amenorrhea were significantly higher in dancers than controls (p < 0.01). Dancer’s energy availability was below the normal range (<30 kcal/kgFFM/day). Despite the presence of certain osteoporosis risk factors such as low energy availability, primary amenorrhoea and lower body weight, professional ballet dancers revealed higher bone density for both cortical and trabecular bone compartments compared to controls. 相似文献

Objective: Little is known about cognition’s effect on jump-landing movement patterns. Design: Participants completed three baseline cognitive tasks. Then, participants performed three jump-landing trials per condition (dual-task trials (DT)): Stroop Color Word test (SCWT), Symbol Digits Modalities test (SDMT), Brooks Visuospatial task (BVT), and no concurrent cognitive task (single-task). Main Outcome Measures: Total Landing Error Scoring System (LESS) scores were used to evaluate movement patterns. Participant’s reaction time (RT) for the jump-landing task was recorded. Results: LESS scores were not different between conditions (F3, 17 = 1.77, p = 0.16). RT was different between DT-SCWT and single-task (difference = ?0.107 sec, SD = 0.095) and DT-SDMT and single-task (difference = ?0.164 sec, SD = 0.245). Additionally, correctness on the BVT (t19 = 2.57, p = 0.019) and SDMT (t19 = 2.93, p = 0.009) decreased significantly during the dual-task condition relative to baseline task scores. Conclusion: Individuals slowed their RT and were less accurate on the cognitive task during a dual-task condition to create an appropriate jump-landing movement. 相似文献

Taking our lead from Rainer Maria Rilke’s (1929) ‘Letters to a Young Poet’, our broader project aimed to create a space for dialogue and intergenerational learning between Physical Education and Sport Pedagogy (PESP) Early Career Academics (ECAs) and members of the PESP professoriate. This paper focuses specifically on the experiences of PESP ECAs. We draw upon narratives of thirty ECAs from nine different countries to gain insight into the experiences, joys, challenges and ambitions they associate with being and becoming a PESP academic. A narrative analysis of the data generated by the ECAs was undertaken. The analysis aimed to be holistic in nature, interested in form and content: both the told (the content) and the telling (how it was told). We initially focused our analysis using the six dimensions of narrative (characters, setting, events, audience, causal relations and themes). Bourdieu’s socio-analytical toolkit complemented our narrative analysis and helped us move beyond the personal narratives by linking them to the broader social practices, relations and structures of the various settings or fields (PESP, university, family) within which the participants function. The findings suggest that many ECAs are experiencing crises of habitus, as they work to suppress ethical dispositions and values and adjust to ‘the rules’ that universities increasingly play by. Our discussion engages with the affective costs of playing by these rules, and recruits Bourdieu’s notion of ‘reflexive vigilance’ to advocate for ongoing critical analysis of how power operates in the various field which academics inhabit. 相似文献
