Using data from the National Longitudinal Survey of Youth ( N  =   1,159), this study reexamines the link between maternal reports of television viewing at ages 1 and 3 and attention problems at age 7. This work represents a reanalysis and extension of recent research suggesting young children's television viewing causes subsequent attention problems. The nonlinear specification reveals the association between television watching and attention problems exists—if at all—only at very high levels of viewing. Adding 2 covariates to the regression model eliminated even this modest effect. The earlier findings are not robust. This study also considers whether its own findings are sensitive to unobserved confounding using fixed-effects estimation. In general, it finds no meaningful relation between television viewing and attention problems.  相似文献

Using phenomenological methodology, the authors explored the experiences of 11 men in a master's‐level counseling program. Participants described the challenges and advantages of being a minority in number, being in a relational environment, and having an awareness of a patriarchal system. These findings suggest the importance of counselor educator awareness of the unique barriers male students face.  相似文献

We analyze longitudinal data from students who spent their academic careers in North Carolina (NC) public secondary schools and attended NC public universities to investigate the importance of high school racial composition and opportunities to learn in secondary school for choosing a science, technology, engineering, and mathematics (STEM) major. We consider school racial composition and opportunities to learn as contexts that shape students' decisions regarding college majors. Results of cross‐classified hierarchical logistic models indicate that attending schools with predominantly White students is negatively associated with declaring a STEM major and with graduating with a STEM major irrespective of students' own race. The finding suggests that for students in North Carolina, attending racially isolated White high schools is related to a decrease in adolescents' participation in STEM during college.  相似文献

School psychologists spend a great deal of time translating assessment results into a psychoeducational report. The importance of creating reports that are both useful and understandable to the readers of the report while also being efficient for the school psychologist cannot be overstated. This study examines parent and teacher perceptions regarding the quality, understandability, and usefulness of school‐based psychological reports. Results of the surveys indicate that both parents and teachers perceive psychological reports as focusing more on tests and test scores as opposed to information that helps to understand the child or assists with intervention development. Strategies for upgrading reports to better meet the needs of parent and teacher readers are discussed.  相似文献

In this study, the authors empirically test a model of sport behaviour that integrates both team identification and a network theory approach to understand attendance at intercollegiate ice hockey games. Grounded within the brand community triad, ego network data were collected among attendees to measure the fan-to-fan connections that constitute the horizontal relationships of brand community participants. Additionally, a multidimensional team identification measure was used to illustrate the vertical relationship between individual and team. Both measures were included in a structural equation model to test how both fan-to-fan and fan-team relationships explain attendance. The results from the model support the salience of both dimensions of the brand community triad, suggesting that understanding sport fan behaviour necessitates including both psychological and structural elements of behaviour. Future suggestions for extending the study of sport fans through structural networks are discussed.  相似文献

This review poses three key issues that will progress our understanding of the sport expertise literature and its translational scientific impact. Primarily relying on research conducted in interceptive sport tasks, and to a lesser extent team sports, we review the perceptual-cognitive skills of sports experts and explore the challenge of designing a sufficiently representative task to examine expertise. We focus on the methodological challenges presented by the reciprocal relationship between players’ action capabilities and their perceptual-cognitive skill. Second, we consider the need for a paradigm shift in the experimental approach used when examining the development of sport expertise. In short, a shift from traditional expert-novice designs to more prospective longitudinal designs that cross-sectionally track the development of expertise is discussed. The final issue considers how the volume of in situ data now collected provides a rich source of information that sport expertise researchers have only begun to consider and integrate with more traditional sport psychology research. We demonstrate how statistical approaches that have described the likely trajectories of expert performers on their journey toward expertise coupled with more traditional qualitative experimental approaches can provide useful insights into the development of psychological performance skills and more broadly sport expertise.  相似文献

Autonomy describes cognition or behavior that is self-directed, according to personal interests, and free from external influence. This construct is of importance to students who are deaf because it has been shown to be positively related to their post-school transition outcomes, and this population faces unique challenges in this area. To conduct research with this construct, it is necessary to use measures that are valid and reliable for the population of interest. Therefore, a set of exploratory and confirmatory factor analyses validated the unidimensionality of a shortened form of the ARC Self-Determination Scale’s autonomy dimension. A three-factor solution, including a social skills dimension, was measurement-invariant across many groups of students, including those with learning disabilities, emotional disturbances, speech and language impairments, and other health impairments. Although the shortened form of this scale was not unidimensional, as hypothesized, the generalizability of its measurement properties may prove useful. Discussion highlights the differences between these three dimensions and Wehmeyer's theory of self-determination.  相似文献

This article describes an approach for training a variety of species to learn the abstract concept of same/different, which in turn forms the basis for testing proactive interference and list memory. The stimulus set for concept-learning training was progressively doubled from 8, 16, 32, 64, 128 . . . to 1,024 different pictures with novel-stimulus transfer following learning. All species fully learned the same/different abstract concept: capuchin and rhesus monkeys learned more readily than pigeons; nutcrackers and magpies were at least equivalent to monkeys and transferred somewhat better following initial training sets. A similar task using the 1,024-picture set plus delays was used to test proactive interference on occasional trials. Pigeons revealed greater interference with 10-s than with 1-s delays, whereas delay time had no effect on rhesus monkeys, suggesting that the monkeys’ interference was event based. This same single-item same/different task was expanded to a 4-item list memory task to test animal list memory. Humans were tested similarly with lists of kaleidoscope pictures. Delays between the list and test were manipulated, resulting in strong initial recency effects (i.e., strong 4th-item memory) at short delays and changing to a strong primacy effect (i.e., strong 1st-item memory) at long delays (pigeons 0-s to 10-s delays; monkeys 0-s to 30-s delays; humans 0-s to 100-s delays). Results and findings are discussed in terms of these species’ cognition and memory comparisons, evolutionary implications, and future directions for testing other species in these synergistically related tasks.  相似文献

本节介绍制定低碳发展计划常用的核心步骤。本指南侧重城市层面;同样的步骤也适用于企业、市、省和国家等层级。中国自"十一五规划"起,对改善国内能源强度定出目标,包括各经济部门的节能目标。2009年12月中国政府公布了其碳强度目标,重点放在单位GDP用能引发的二氧化碳排放量。为实现该强度目标以及"循环经济"等经济性目标,制定低碳发展规划尤其必要。  相似文献
