This study investigated the relationship between dispositional achievement goal orientation (task and ego) and coping ability in wheelchair rugby players with quadriplegia. The sample consisted of 16 (15 males and 1 female) players between the ages of 25 and 44 (M=33.7 years; SD=8.7) who were selected for South Africa's national training squad in preparation for the 2011 International Wheelchair Rugby Federation (IWRF) Asia-Oceania Championship. Players self-reported on their perception of success and athletic coping skills. The data were analysed for correlational associations between dimensions of achievement goal orientation and psychological skills associated with coping in sport. Findings revealed that players have both high task and fairly high ego orientation of which task orientation was significantly correlated with coping ability.  相似文献

I. It was hypothesized that male Ss will project more on situations pertaining to the lives of men than on situations pertaining to the lives of women and that female Ss will project more on situations pertaining to the lives of women than on situations pertaining to the lives of men.

II. It was further hypothesized that male Ss and female Ss will not differ with regard to the amount of projection elicited by male and female pictorial figures. Transcendence Indices were used as measures of the amount of projection. Ss were 30 male college students and their wives. Hypothesis I was confirmed for men only. Hypothesis II was confirmed for men and for women.  相似文献

This study examined the experience of mothering in adolescence in the context of romantic involvement and social support. 30 adolescent mothers completed measures of adolescent self-development and motherhood, romantic relationship experience, availability of and satisfaction with social support, and parenting stress. Findings suggest that young mothers benefit greatly from the support of a partner, as evidenced by a more functional understanding of motherhood and the maternal role, greater satisfaction with social support, and lower levels of psychological distress. Education on social support should be made available to young mothers to address stress associated with adolescent parenting.  相似文献

Aging is typically related to changes in brain and cognition, but the aging process is heterogeneous and differs between individuals. Recent research has started investigating the influence of cognitive and physical training on cognitive performance, functional brain activity, and brain structure in old age. The functional relevance of neural changes and the interactions among these changes following interventions is still a matter of debate. Here we selectively review research on structural and functional brain correlates of training-induced performance changes in healthy older adults and present exemplary longitudinal intervention studies sorted by the type of training applied (i.e., strategy-based training, process-specific training, and physical exercise). Although many training studies have been conducted recently, within each task domain, the number of studies that used comparable methods and techniques to assess behavioral and neural changes is limited. We suggest that future studies should include a multimodal approach to enhance the understanding of the relation between different levels of brain changes in aging and those changes that result from training. Investigating inter-individual differences in intervention-induced behavioral and neuronal changes would provide more information about who would benefit from a specific intervention and why. In addition, a more systematic examination of the time course of training-related structural and functional changes would improve the current level of knowledge about how learning is implemented in the brain and facilitate our understanding of contradictory results.  相似文献

The transition from primary to secondary school is a major life event for eleven-year-old children in the United Kingdom, where they face simultaneous changes. Following the outbreak of Covid-19, transfer children face additional uncertainty on top of this. Negotiation of the multiple challenges, combined with the reduced support associated with Covid-19, could have a negative impact on children’s school adjustment and mental health. Given the rapidity of changes associated with Covid-19, there are key empirical and practical gaps on how best to support children as they negotiate these two key events. To date, there is no published research which has explored the experiences of transfer children, and that of their parents and teachers during this time. The present research aimed to narrow this research gap by answering the research question: What are parents’, children’s, and teachers’ experiences of primary-secondary school transition during Covid-19? This research used a series of UK wide surveys to gather data from 101 Year 7 children, 88 Year 7 parents, 26 primary school teachers, and 40 secondary school teachers using a mixture of open and closed questions. The data were analysed using Thematic Framework Analysis, taking an inductive-open coding approach. All three stakeholders reported negative impacts of Covid-19 on the transition, for example, in terms of missed opportunities. There were also many comments about the emotional impact of Covid-19 on children, parents, and teachers. Numerous strategies were reported that were used to meet children’s needs pre and post-transition, highlighting areas of good practice, along with practical suggestions for how to approach transition in the future. The study has identified ways that transition can be managed more effectively, thus, having short term implications in providing an evidence base to support transfer children this year, and long-term implications for future transition years.  相似文献

Genetic testing and counseling have become integral to the timely control of heritable cancers, like the childhood eye cancer retinoblastoma. This study aimed to determine attitudes, knowledge and experiences related to retinoblastoma genetics, among survivors and parents of children with retinoblastoma in Kenya. This qualitative study used focus groups as the primary data collection method, coupled with a brief demographic questionnaire. Study settings were Kenyatta National Hospital and Presbyterian Church of East Africa Kikuyu Hospital. Thematic analysis was used to identify key themes. Thirty-one individuals participated in five focus groups. Two main concepts emerged: (1) the origins of retinoblastoma are unclear, and (2) retinoblastoma is associated with significant challenges. The lack of clarity surrounding the origins of retinoblastoma was linked to limited knowledge of retinoblastoma genetics, and limited genetic counseling delivery and uptake. The challenges associated with retinoblastoma were discussed in terms of the impact of the diagnosis on individuals and families, and unmet healthcare needs related to the diagnosis. Next steps will incorporate these findings to develop evidence-informed and accessible cancer genetic services in Kenya.  相似文献

This position paper presents the state-of-the art of the field of workplace commitment. Yet, for workplace commitment to stay relevant, it is necessary to look beyond current practice and to extrapolate trends to envision what will be needed in future research. Therefore, the aim of this paper is twofold, first, to consolidate our current understanding of workplace commitment in contemporary work settings and, second, to look into the future by identifying and discussing avenues for future research. Representative of the changing nature of work, we explicitly conceptualize workplace commitment in reference to (A) “Temporary work”, and (B) “Cross-boundary work”. Progressing from these two themes, conceptual, theoretical and methodological advances of the field are discussed. The result is the identification of 10 key paths of research to pursues, a shared agenda for the most promising and needed directions for future research and recommendations for how these will translate into practice.  相似文献

Brain imaging studies provide strong evidence for the involvement of the human mirror system during the observation of complex movements, depending on the individual's motor expertise. Here, we ask the question whether motor expertise not only affects perception while observing movements, but also benefits perception while solving mental rotation tasks. Specifically, motor expertise should only influence the performance in mental body rotation tasks (MBRT) with left-right judgment, evoking a perspective transformation, whereas motor expertise should not affect the MBRT with same-different judgment, evoking an object-related transformation. Participants with and without motor expertise for rotational movements were tested in these two conditions in the MBRT. Results showed that motor experience selectively affected performance in the MBRT with the left-right judgment, but not with same-different judgment. More precisely, motor expertise only benefited performance when human figures were presented in (for non-experts) unfamiliar, upside-down body orientations.  相似文献
