Previous research has argued that skills acquired explicitly are more likely to fail under stressful conditions than skills that have been learned implicitly. The present study addressed an alternative explanation for the robustness under stress of implicit task performance. As implicit learners acquired the skill of golf putting while generating random letters, it is possible that they became desensitized to self-generated verbalizations and thus immune to the effects of competitive anxiety. We tested this interpretation while controlling for a further rival hypothesis generated by Eysenck's Processing Efficiency Theory. We also examined the effect of increased state anxiety on the kinematic processes underlying performance breakdowns. For task performance, we found evidence that partially supported the conscious processing hypothesis, while the results of the kinematic analysis of the putting stroke were equivocal. Analysis of self-reported effort scores provided partial support for processing efficiency theory. 相似文献

This paper considers the relationship between stress and cognitive functioning and discusses some of the concepts and methods that may be adopted to examine the relationship between stress and sports performance. It considers only that literature that may be relevant to, or furthers, the understanding of sports performance under competitive stress. One of the most popular approaches has been to explain the relationship in terms of the unidimensional inverted-U hypothesis. The validity of this approach to explaining sports performances in specific situations is discussed and it is generally concluded that the inverted-U hypothesis is too vague and simplistic. The discussion considers multidimensional approaches and discusses the suitability and implications of some more recent and more complex models of stress and performance which are now available in the psychological literature. It is concluded that the relationship between stress and sports performance is an extremely complex one and involves the interaction between the nature of the stressor, the cognitive demands of the task being performed and the psychological characteristics of the individuals performing it. 相似文献

This paper presents a method of general geometrical definitions of screw machine rotors and their manufacturing tools. It
describes the details of lobe shape specification, and focuses on a new lobe profile, which yields a larger cross-sectional
area and shorter sealing lines resulting in higher delivery rates for the same tip speed. A well proven mathematical model
was used to determine the optimum profile, compressor housing size, and compressor ports to achieve the superior compressors. 相似文献

This paper provides insights into teacher and school-based administrators’ responses to policy demands for improved outcomes on high-stakes, standardised literacy and numeracy tests in Australia. Specifically, the research reveals the effects of the National Assessment Program – Literacy and Numeracy (NAPLAN), and associated policies, in the state of Queensland. Drawing suggestively across Michel Foucault’s notions of disciplinary power and subjectivity, and Pierre Bourdieu’s concept of social fields, the research utilises interviews with teachers and school-based administrators to reveal how high-stakes, standardised testing practices served to discursively constitute performative teacher subjectivities around issues of funding, teacher and school reputation and target-setting within what is described as the ‘field of schooling practices’. The paper argues that the contestation evident within this field is also reflective and constitutive of more educative schooling discourses and practices, even as performative logics dominate. 相似文献

This paper draws upon the sociology of numbers, particularly work by Theodore Porter, to reveal the multifarious ways in which numbers actively constitute practices in schools. Drawing upon a case study of one low-performing school in a low-performing region in the state of Queensland, Australia, and theorising into the sociology of numbers, the research explores the complex ways in which numbers came to constitute and dominate the practices in this school site under a broader national, state and regional policy context demanding rapid improvements in various forms of standardised tests and associated practices. Specifically, the research reveals a strong and simultaneous focus by teachers upon a variety of numeric data collected at national, regional and local levels, and intricate relations between these data; multiple visualisation, triangulation and comparison approaches towards such data in virtual and physical formats; and the enumerative nominalisation of both students and their reading attainment in relation to specific, concretised levels of achievement and various types of scale scores. The research cautions against the sheer volume of such enumerative practices, which, while productive of teachers’ understandings of student capacity against standardised measures of achievement, may also lead to a more reductive view of education, dominated by concerns about achievement in standardised tests (and associated practices) alone. 相似文献
