ObjectivesThis review aims to (a) identify correlates of youth sport attrition, (b) frame correlates within a multilevel model of youth sport participation (i.e., biological, intra-personal, inter-personal, institutional, community, and policy levels), and (c) assess the level of evidence for each correlate.DesignReview paper.MethodsSystematic review method.ResultsEntering relevant search terms into PubMed, PsycINFO, SPORTDiscus and Web of Knowledge databases identified 23 articles with a total of 8345 participants. Satisfactory articles largely examined sport-specific attrition and sampled youth from western countries (e.g., Canada, France, Spain, United States). Of the 141 correlates examined, most were framed at the intrapersonal (90) and inter-personal levels (43). The level of evidence for each correlate (i.e., high, low, insufficient) was systematically assessed based on the quantity and quality of supporting articles. In total, 11 correlates were categorized as having a high quality level of evidence and 10 as having a low quality. High quality correlates included, among others, age, autonomy, perceived competence, relatedness, and task climate.ConclusionsOverall, established correlates of youth sport attrition are largely social in nature. Future directions surrounding (a) the need to examine correlates at lower (i.e., biological level) and higher (i.e., institutional, community, policy) analytic levels, (b) to sample participants from more culturally diverse societies and (c) to examine sport-general attrition are offered. 相似文献

This commentary complements Stanley et al.'s (2022) target article by concentrating on the process of false belief construction and its associated cognitive mechanisms. It also concurs with the target article that a deeper understanding of the cognitive mechanisms by which consumers revise their truth judgments in view of new evidence is needed. Specifically, this essay develops two main dimensions: the first about what we know from the actual construction of truth judgments; the second about what we know from the cognitive mechanisms by which truth judgments are constructed. Particularly on this second dimension, I develop the idea that relational reasoning is key to understanding how individuals integrate new information within their internal belief systems. These two dimensions are both process-minded, yet one is about how beliefs evolve over time, whereas the other is about the cognitive mechanisms that underlie belief construction. Overall, an understanding of these two elements is crucial to finding behavioral interventions that may curb the spread of misinformation. 相似文献

Grounded in social cognitive theory (SCT), this study sought to examine whether parents perceived social cognitive factors regarding children's physical activity (PA) behaviors were associated with preschool children's moderate-to-vigorous PA (MVPA) levels. A total of 142 Hong Kong parent-child pairs from five preschools/childcare centers completed all assessments in the cross-sectional study. Children’s (42% girls; mean age = 4.52 ± 0.67 years) PA was measured through accelerometers. Parents (74% mothers; mean age = 37.38 ± 4.63 years) completed a paper-based questionnaire assessing the social cognitive factors on their children’s PA participation. The data were analyzed using latent variable structural equation modeling. Findings revealed that the model showed acceptable fit with the data: χ2 (23) = 38.14, p = .025, χ2/df = 1.66, CFI = 0.955, TLI = 0.929, RMSEA = 0.068, 90% CI [0.025, 0.106], and SRMR = 0.072. The model accounted for 39.1% of the variance in the PA behavior of preschool-aged children. Structural equation modelling revealed parental self-efficacy (β = 0.29, 95% CI [0.95, 0.49]) and goal setting (β = 0.25, 95% CI [0.06, 0.44]) were directly associated with children’s MVPA. Outcome expectations (β = 0.09, 95% CI [0.01, 0.03]) and goal setting (β = 0.18, 95% CI [0.05, 0.32]) mediated the association between parental self-efficacy and children’s MVPA. Indirect associations of parental self-efficacy from setting goals via parental support (β = 0.15, 95%CI [0.02, 0.30]) and perceived barriers (β = 0.15, 95% CI [0.05, 0.28]) were uncovered. Results supported the use of SCT in understanding how the parents perceived social cognitive factors predict the PA behaviors of young children. This study provides insight into whether these theoretical variables could be modified or promoted in future intervention programs. Enhancing parents’ abilities to ensure preschool-aged children are physically active is of great importance given the global decline in PA among children. 相似文献

While a growing number of studies have highlighted the potential of virtual reality (VR) to improve athletes’ skills, no research has yet focused on acceptance of a VR head-mounted display (VR-HMD) designed to increase sport performance. However, even if technological devices could potentially lead to performance improvement, athletes may not always accept them. To investigate this issue, the Technology Acceptance Model (TAM) examines if perceived usefulness, perceived ease of use, perceived enjoyment, and subjective norms (i.e., social influence) are positive predictors of intention to use a specific technology. The aims of the present study were to test with competitive athletes the validity of the TAM before a first use of a VR-HMD intended to enhance sport performance and to examine to what extent the level of practice and the type of sport practiced have an influence on the previous variables of the TAM. The study sample comprised 1162 French athletes (472 women, 690 men, Mage = 24.50 ± 8.51 years) who usually practiced a sport in competition (from recreational to international level). After reading a short text presenting the VR-HMD and its interests for sport performance, the participants filled out an online questionnaire assessing their acceptance of this technological device before a first use. The results of the structural equation modeling analysis revealed that perceived usefulness, perceived ease of use, perceived enjoyment, and subjective norms were positive predictors of intention to use this VR-HMD, validating the suitability of the TAM for investigating the acceptance by athletes of a VR-HMD designed to increase their sport performance. The results also showed that athletes of all sport levels (a) had a significant intention to use VR, (b) found it quite useful (except for recreational athletes), quite easy to use, and quite pleasant to use, even if their entourage would not encourage them to use it (except for international athletes), and (c) found the VR-HMD easy and pleasant to use whatever the sport practiced. Notably some athletes (e.g., triathletes, swimmers, cyclists) did not find the VR-HMD significantly useful and did not have significant intention to use it to increase their performance. Identifying acceptance by athletes of such a device may increase the likelihood that it will be used by athletes of different levels and from different sports, so that they can benefit from all its advantages related to the improvement of their sport performance. Needs-based targeted interventions may also be conducted toward athletes who might be reluctant to integrate this type of device into their training. 相似文献

认知控制的主要研究范式之一是任务切换。以往研究发现切换代价受到认知控制层级性的调节, 但鲜有研究探索这一调节过程的动态神经机制。本研究通过嵌套的线索-任务切换范式考察不同层级任务切换代价的差异及其神经机制。在实验中, 要求被试完成高低两种层级任务, 低层级任务要求被试判断数字大小(或奇偶); 高层级任务则须先加工数字的某一语义特征(如当前数字是否是偶数), 然后进行大小判断。行为结果表明, 高层级任务切换代价显著大于低层级任务切换代价。线索锁时的脑电结果表明, 层级效应最早出现于P2成分, 切换效应(切换与重复之差)在CNV成分上受到任务层级的调控, 反映了在任务目标重构阶段给予高层级任务更多的选择性注意以及更高的主动性控制。目标锁时的脑电结果表明, 在N2及慢波(SP)成分上, 高层级任务切换与重复的波幅差异相比低层级任务显著更大, 反映了在抑制旧任务集与重构新反应集的过程中增强的反应性控制。这些结果为任务设置重构论和认知控制的层级性提供了新的证据。 相似文献

In honor of the life and work of Aaron T. Beck, this paper describes the application of cognitive therapy to management of marginalization stress among minoritized communities. Collaborative empiricism, cognitive restructuring, and behavioral interventions are highlighted as being particularly useful in a contemporary multicultural approach for the anxiety, depression, stress, and other sequelae of marginalization due to a stigmatized identity. Although primarily illustrated through recent work with transgender and gender diverse adults, the discussion extends to other groups including racial, ethnic, and sexual minorities and immigrants. This work illustrates the power of Dr. Beck’s approach to address the presenting concerns of contemporary clinical work. 相似文献
