There is increasing evidence that children display high levels of weight and muscle concerns, which include body dissatisfaction and problem eating. In order to address these issues, researchers have designed and implemented prevention programs for this age group. Thirteen published studies were located and reviewed, with children aged 8-12 years from elementary schools, or equivalent. Overall, the programs were shown to be effective in improving children's knowledge at post-test and at follow-up assessments. However, there is limited evidence to show that the programs reduced or prevented body image concerns and/or problem eating. Too few studies have examined muscle concerns so no conclusions can yet be drawn about this domain. Limitations of the studies and suggestions for future prevention efforts are discussed. 相似文献

After years of walking practice 8-10-year-old children with typical development (TD) and those with Down syndrome (DS) show uniquely different but efficient use of dynamic resources to walk overground and on a treadmill [Ulrich, B.D., Haehl, V., Buzzi, U., Kubo, M., & Holt, K.G. (2004). Modeling dynamic resource utilization in populations with unique constraints: Preadolescents with and without Down syndrome. Human Movement Science, 23, 133-156]. Here we examined the use of global stiffness and angular impulse when walking emerged and across the ensuing months of practice in eight toddlers with TD and eight with DS. Participants visited our lab when first able to walk four to six steps, and at one, three, four, and six months of walking experience. For all visits, toddlers walked overground at their preferred speeds and for the last two visits on a treadmill. Toddlers with TD and DS demonstrated clear and similar developmental trajectories over this period with more similarities than differences between groups. At six months stiffness and impulse values were higher than previously observed for 8-10-year-old children. Stiffness values increased significantly throughout this period, though rate of change slowed for the TD group by three months of experience. Impulse values rose sharply initially and slowed to plateau during the latter months. Treadmill data illustrated toddlers' capacity to adapt dynamic resource use to imposed changes in speed, particularly well after six months of practice. Consistent with our studies of preadolescents and older adults, toddlers with DS produced significantly wider normalized step width than their TD peers. We propose that the challenge of upright bipedal locomotion constrains toddlers with TD and DS to generate similar, necessary and sufficient stiffness and impulse values to walk as they gain control and adapt to playful and self-imposed perturbations of gait over the first six months. The plateau in impulse and slow-down of stiffness increases over the latter months may be the first signs of a downward trend to the lower values produced by older children with several years of walking experience. 相似文献

Presenting a blank line-up—containing only fillers—to witnesses prior to showing a real line-up might be useful for screening out those who pick from the blank line-up as unreliable witnesses. We show that the effectiveness of this procedure varies depending on instructions given to witnesses. Participants (N = 462) viewed a simulated crime and attempted to identify the perpetrator from a line-up approximately 1 week later. Rejecting a blank line-up was associated with greater identification accuracy and greater diagnosticity of suspect identifications, but only when witnesses were instructed prior to the blank line-up that they would view a series of line-ups; the procedure was ineffective for screening when witnesses were advised they would view two line-ups or received no instruction. These results highlight the importance of instructions used in the blank line-up procedure, and the need for better understanding of how to interpret choosing patterns in this paradigm. 相似文献

ABSTRACT The current study investigated whether a 5-month, adult mentoring intervention delivered by school personnel could enhance the school engagement of ninth grade urban minority adolescents. Compared to 20 at-risk students who did not receive an intervention, 20 at-risk students who were randomly assigned to mentoring exhibited significantly less decline during the first year of high school in perceived teacher support and decision making and were less likely to enter the discipline system. The effects were stronger and included sense of school belonging for participants who were “mentored as intended.” Moreover, mentee and mentor reports of relationship quality were associated with changes in mentored participants' school-related cognitions and behaviors. The findings indicate that adult mentoring may help to prevent normative declines in urban minority youths' school engagement. 相似文献

This article constructs a dialogue between Julian of Norwich and the concept of “theologian of the cross,” as found in Martin Luther and his recent interpreters. Since she is Catholic and medieval, one might begin by suspecting that her theology is not acceptable to someone who follows Luther's teaching in the Heidelberg Disputation. However a closer look will suggest that what she has to say is largely in accord with Luther's standard for a theologian of the cross. Put more positively, Julian is a theologian of the cross, in spite of her use of different language and concepts from those of Luther. The focus of the article is the subject of prayer: what Julian teaches about it, and what may be inferred about prayer from Luther's dramatic theses in his disputation. 相似文献

The purpose of this study was to identify junior tennis players’ preferences for parental behaviors at competitions. Eleven focus groups were conducted with 42 high performance Canadian tennis players (M age = 13.5 yrs, SD = 1.2 yrs). Analysis revealed several themes describing athletes’ views of supportive parental behaviors. Specific preferences were that parents should not provide technical and tactical advice, but they should comment on effort and attitude, provide practical advice, respect tennis etiquette, and match nonverbal behaviors with supportive comments. By providing a children's perspective, these findings offer guidance to enhance parental involvement in tennis. 相似文献

Theory and literature suggests that the reason religiously involved people tend to have good health outcomes is because they have healthy lifestyles and behaviors in accord with religious beliefs. Other literature suggests that religious involvement may play a negative role in health outcomes due to beliefs about illness originating as punishment for sins. These ideas were tested as part of a theoretical model of the religion–health connection in a national sample of African Americans. Outcomes included a variety of health-related behaviors. Study participants (N = 2,370) randomly selected from a U.S. national call list completed a telephone survey assessing religious involvement, health behaviors, and demographic characteristics. Structural equation modeling was used to analyze study data. Findings indicate that perceived religious influence on health behavior mediated the relationship between religious beliefs and behaviors and higher fruit consumption and lower alcohol use and smoking. Belief that illness is the result of punishment for sin mediated the relationship between (a) religious beliefs and higher vegetable consumption and lower binge drinking and (b) religious behaviors and lower vegetable consumption and higher binge drinking. These findings could be applied to health education activities conducted in African American faith-based organizations, such as health ministries, in the effort to eliminate health disparities. 相似文献

Although speech categories are defined by multiple acoustic dimensions, some are perceptually weighted more than others and there are residual effects of native-language weightings in non-native speech perception. Recent research on nonlinguistic sound category learning suggests that the distribution characteristics of experienced sounds influence perceptual cue weights: Increasing variability across a dimension leads listeners to rely upon it less in subsequent category learning (Holt & Lotto, 2006). The present experiment investigated the implications of this among native Japanese learning English /r/-/l/ categories. Training was accomplished using a videogame paradigm that emphasizes associations among sound categories, visual information, and players' responses to videogame characters rather than overt categorization or explicit feedback. Subjects who played the game for 2.5h across 5 days exhibited improvements in /r/-/l/ perception on par with 2-4 weeks of explicit categorization training in previous research and exhibited a shift toward more native-like perceptual cue weights. 相似文献
