Focusing strategies are known to play a significant role in motor performance, with individuals who use an internal focus on body movement typically showing poorer outcomes than those who focus on features of the external environment. Focus of attention and switching of one's focus are examined in the context of two different complex motor skills along with a factor not previously examined systematically, individual preference. In both experiments, participants were introduced to focusing strategies that might be employed when attempting a sensorimotor task. Explanations of both strategies were given to participants. Specifically, for an internal focus, participants were instructed to concentrate on their body movements, while for an external focus, they were instructed to focus on aspects in the environment. They were then asked which strategy they preferred. Participants then continued either with their preferred focus or were instructed to switch to their non-preferred focus. The advantage that the external focus typically enjoys turns out not to be a simple one and interacts with individual preference and with the "forced-opposite" manipulation. Our results support the growing consensus that encouraging individuals to adopt an internal focusing strategy is counterproductive in complex sensorimotor tasks. They also suggest that individual preferences play a role. 相似文献

We provide an overview of a recently published, edited book in a rapidly emerging field of research, policy, and practice for physical activity: Sedentary Behavior and Health. In this commentary, we highlight the broad perspectives provided in the 27 chapters of Sedentary Behavior and Health and suggest a research strategy to move the field forward—not only with scientific rigor, but also with breadth of scholarship. The book’s chapters provide an overview of the background to and contexts for sedentary behavior and health. They then highlight the importance of understanding health consequences and underlying mechanisms; introduce key measurement technology and analytic strategies; consider sedentary behavior in subpopulations; describe conceptual models and theories to guide sedentary behavior interventions; and explain what is known about interventions in different settings. Considering the breadth of perspectives brought to bear on the field and the plethora of opportunities for research, policy, and practice, we suggest 3 elements of an interdisciplinary research strategy drawing upon the primary knowledge bases of physical activity and health: through the experimental methods of exercise science, through the observational tools of epidemiology, and through the conceptual approaches and methods of behavioral science. A better understanding of the health consequences of sedentary behavior and how they may be influenced can be encompassed by 3 key questions: What changes are needed to most effectively influence sedentary behaviors? What elements of sedentary behavior should be changed to improve health outcomes? What are the feasibility of and the benefits from changing sedentary behavior? 相似文献

Jane C. Owen 《Multicultural Perspectives》2013,15(3):60-63
The journey toward becoming a multicultural person is not easy and is never finished. As an educational administrator in a tri-cultural state, I felt comfortable that I was proficient in dealing with diversity. Only when I began a doctoral program at a major Texas university was my naivety exposed. I quickly learned that experience in working with diverse populations and the ability to relate effectively to people of different ethnic backgrounds were vastly different. The two years I spent deeply immersed in a multiculturally rich cohort of doctoral students changed me. My eyes were opened to injustices that I had never before seen as I vicariously experienced life through the eyes of the “other.” Today, I am a professor at a regional university. My experiences, focused through the lens of theory, are the basis for the message to my students. I have traveled the road before and can now point the way toward a broader definition of acceptance and tolerance. 相似文献

Elementary (primary) and high (secondary) school education in Northern Ireland (NI) is essentially segregated along religious lines. The vast majority of young people from the Protestant/Unionist/British community attend state “Controlled” schools while Catholics/ Nationalists/Irish attend schools in the Catholic Church‐based “Maintained” sector. Going to university represents for many the first opportunity to share a significant educational experience with someone from a different politico‐religious group and cultural background. This paper presents the results of a focus‐group based study designed to illuminate students' experiences of intergroup relations at a NI university. Through focus‐group discussions information was generated on cross‐community contact, the influence of group difference, prevalence, and identity, on attitudes and intergroup communication. The university environment as a factor in potential relational development, the role which student bodies and academic staff may play, and policies and practices on accepting diversity are discussed. Recommendations and considerations are highlighted for other pedagogical institutes where complex and difficult intergroup dynamics exist. 相似文献

Effects of early child care on children's functioning from 4(1/2) years through the end of 6th grade (M age=12.0 years) were examined in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n=1,364). The results indicated that although parenting was a stronger and more consistent predictor of children's development than early child-care experience, higher quality care predicted higher vocabulary scores and more exposure to center care predicted more teacher-reported externalizing problems. Discussion focuses on mechanisms responsible for these effects, the potential collective consequences of small child-care effects, and the importance of the ongoing follow-up at age 15. 相似文献

It is estimated that in 1986 40‐50% of children in England aged 3 and 4 were attending pre‐school playgroups. Another 20% were receiving education in nursery schools and classes, mostly part time, whilst a further 20% were in the reception classes of infant schools, mostly full time. Using data on the provision of these services within each local authority in England it is shown that the numbers of nursery education and of playgroup places are strongly negatively correlated. Combining these statistics with data from the 1981 Census it is also shown that the rates of provision are strongly related to the socio‐economic characteristics of the authorities, such that playgroups predominate in the more affluent areas whereas high levels of nursery education are found in urban areas with more material disadvantage. 相似文献
