Dimensions of Coaching Behavior, Need Satisfaction, and the Psychological and Physical Welfare of Young Athletes 总被引:1,自引:0,他引:1
Grounded in self-determination theory (E. L. Deci & R. M. Ryan, 2000), the purpose of this study was to examine the relationship of dimensions of coaching behavior to intrinsic need satisfaction and indices of psychological and physical well-being among male adolescent athletes. Participants were 265 British soccer and cricket players (M
age = 16.44). Structural equation modeling analysis, using maximum likelihood robust method, showed athletes' perceptions of autonomy support, mastery focus, and social support from the coach to predict their satisfaction of the needs for autonomy, competence, and relatedness, respectively. The satisfaction of the need for competence emerged as the most important predictor of psychological and physical well-being. The findings suggest that particular aspects of the social environment may be salient for fostering particular psychological needs. The results also underline the importance of perceived competence for the psychological and physical welfare of adolescents in team sports. 相似文献

Over the past several decades, significant advances have been made in our understanding of the basic stages and mechanisms
of mammalian brain development. Studies elucidating the neurobiology of brain development span the levels of neural organization
from the macroanatomic, to the cellular, to the molecular. Together this large body of work provides a picture of brain development
as the product of a complex series of dynamic and adaptive processes operating within a highly constrained, genetically organized
but constantly changing context. The view of brain development that has emerged from the developmental neurobiology literature
presents both challenges and opportunities to psychologists seeking to understand the fundamental processes that underlie
social and cognitive development, and the neural systems that mediate them. This chapter is intended to provide an overview
of some very basic principles of brain development, drawn from contemporary developmental neurobiology, that may be of use
to investigators from a wide range of disciplines. 相似文献

Two common behavioral economic simulation tasks used to study cigarette smoking are the Cigarette Purchase Task, a measure of cigarette demand, and delay discounting, a measure of the subjective value of rewards as a function of delays to delivery. Few studies have evaluated whether combining these tasks enhances understanding of smoking beyond either alone. The current study represents an initial evaluation of the intersection between cigarette demand indices and delay discounting among pregnant smokers by examining associations between these measures and whether a woman makes antepartum quit attempts before entering prenatal care (a reliable predictor of eventual quitting). Participants were 159 pregnant women enrolled in a smoking‐cessation trial. Low O max and shallow discounting were each associated with antepartum quit attempts. Participants were next categorized into four subgroups (low O max, shallow discounting; low O max, steep discounting; high O max, shallow discounting; high O max, steep discounting) using median splits. Those with shallow discounting and low O max were more likely to have made quit attempts than each of the other three subgroups. That is, steep discounting appears to undermine the association of low O max and efforts to quit smoking during pregnancy while high O max overshadows any protective influence associated with shallow discounting. 相似文献

This article intends to contribute to the science–religion historiography with two topics—philology and the construction of national identities—that can help provide a more complex picture of the relations between science and religion. We use the life and work of the Mallorcan Catholic priest Antoni Maria Alcover (1862–1932) as a case study that puts language, linguistics, and nationalism on the board of science and religion studies. Alcover was the main driving force of the Catalan Dictionary, a collective enterprise that set out to inventory the complete oral and literary lexicon of this language, and which mobilized thousands of people, many of which were clergymen, from all over the Catalan‐speaking territories. In the article, we will explore Alcover's education; the way he established a link between language, religion, and fatherland; the shaping of his identity as a philologist in the image mainly of new German notions and practices; as well as his role in the institutionalization process of the Catalan language as a scientific language, as a language for science and for religion. 相似文献

This study was designed to assess the development of spatial attentional orienting during the school‐age years. To that end, we used a cost‐benefit attentional cueing task with short (100 ms) and long (800 ms) cue‐to‐target intervals to examine attentional processing independent of motor skills and perceptual processing in 200 7–17‐year‐olds and 40 adults. We found that orienting attention, disengaging attention and visual processing in an unattended location, were all progressively more accurate and faster with increasing age. Our data thus suggest that the efficiency of attentional orienting improves in an age‐related manner throughout the school‐age years. 相似文献

In the spring of 1983, Drexel University announced that all incoming freshmen the following fall would be required to have access to a personal computer being designed by Apple. This paper reports on the impact of that decision over the next 2 years. 相似文献
