Mental Rotation of Tactical Instruction Displays Affects Information Processing Demand and Execution Accuracy in Basketball     

Till Koopmann  Yvonne Steggemann-Weinrich  Jochen Baumeister 《Research quarterly for exercise and sport》2017,88(3):365-370

Purpose: In sports games, coaches often use tactic boards to present tactical instructions during time-outs (e.g., 20 s to 60 s in basketball). Instructions should be presented in a way that enables fast and errorless information processing for the players. The aim of this study was to test the effect of different orientations of visual tactical displays on observation time and execution performance. High affordances in visual-spatial transformation (e.g., mental rotation processes) might impede information processing and might decrease execution performance with regard to the instructed playing patterns. Method: In a within-subjects design with 1 factor, 10 novice students were instructed with visual tactical instructions of basketball playing patterns with different orientations either showing the playing pattern with low spatial disparity to the players’ on-court perspective (basket on top) or upside down (basket on bottom). Results: The self-chosen time for watching the pattern before execution was significantly shorter and spatial accuracy in pattern execution was significantly higher when the instructional perspective and the real perspective on the basketball court had a congruent orientation. Conclusion: The effects might be explained by interfering mental rotation processes that are necessary to transform the instructional perspective into the players’ actual perspective while standing on the court or imagining themselves standing on the court. According to these results, coaches should align their tactic boards to their players’ on-court viewing perspective.  相似文献   

Comparing the magnitude and direction of asymmetry during the squat,countermovement and drop jump tests in elite youth female soccer players

ABSTRACT

The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists.  相似文献

Screening for problem parenting: preliminary evidence on a promising instrument     

W R Avison  R J Turner  S Noh 《Child abuse & neglect》1986,10(2):157-170

This paper reports on efforts aimed toward the development of more effective procedures for identifying mothers who are at elevated risk for problems in parenting. We present data from two independent samples of known maladaptors and corresponding comparison mothers and report on our attempts to cross-validate a promising screening instrument composed of items that index social support and parenting attitudes. The resultant 20-item scale correctly identified over 90% of maladaptive and comparison mothers. When this scale was cross-validated on a second independent sample of maladaptors and comparison mothers, it was again almost 90% accurate. Issues concerning the field application of this promising instrument are discussed and its possible limitations are considered.  相似文献   

Legacies in Black and White: The Racial Composition of the Legacy Pool     

Howell  Cameron  Turner  Sarah E. 《Research in higher education》2004,45(4):325-351

Selective universities regularly employ policies that favor children of alumni (known as legacies) in undergraduate admissions. Since alumni from selective colleges and universities historically have been disproportionately white, admissions policies that favor legacies have disproportionately benefited white students. For this reason, legacy policies lead to additional costs in terms of reductions in racial diversity. As larger numbers of minority students graduate from colleges and universities and have children, however, the potential pool of legacy applicants will change markedly in racial composition. This analysis begins with a review of the history and objectives of the preference for children of alumni in undergraduate admissions. We then consider the specific case of the University of Virginia and employ demographic techniques to predict the racial composition of the pool of potential legacy applicants to the university. Significant changes in the racial composition of classes that graduated from the University of Virginia from the late 1960s through the 1970s foreshadow similar changes in the characteristics of alumni children maturing through the next two decades.  相似文献   

The Effectiveness of a Brief Mindfulness-Based Intervention for College Freshmen Who Have Aged out of Foster Care     

Lori Gray  Sarah Font  Yvonne Unrau  Ann Dawson 《Innovative Higher Education》2018,43(5):339-352

This study investigated the effects of a brief meditation intervention on perceived stress, mindfulness, and sleep quality for college freshmen who have aged out of foster care. Thirty-six youth who had aged out of foster care and enrolled at a large midwestern 4-year university (n?=?16 experimental group, n?=?20 control group) participated in a study in which they were assessed three times on the dependent variables. Students also participated in a focus group after the intervention ended. Four sessions of the brief mindfulness intervention resulted in significant short-term reductions in stress levels and increases in sleep quality. Finding effective personal interventions to increase chances for college success for students with histories in foster care can also offer potential insight toward the development of educational models and resources for other vulnerable college student populations.  相似文献   

TAKING ACCOUNT OF STUDENTS’ EMPLOYMENT EXPERIENCE IN A COURSE OF INITIAL TEACHER EDUCATION     

Christopher Turner  Michael Williams 《Assessment & Evaluation in Higher Education》1992,17(2):101-110

This study focuses on an industrial, commercial and community experience programme within a full time, one year postgraduate teacher training course. Acknowledging the heterogeneous experiences brought to this course by the students, an attempt was made to detect links between the students’ prior experience and their experience of the industrial, commercial and community programme. The students completed questionnaires before and after a placement and the findings are described. These findings contribute to an evaluation of the programme and suggest a number of important questions for those responsible for designing teacher education courses.  相似文献   

Translating Policy into Practice: the teaching and learning experience     

Yvonne Farr‐Wharton 《Assessment & Evaluation in Higher Education》1997,22(2):211-224

Student diversity has increased within Australian universities. This has changed the teaching and learning needs of students. The implementation of quality was aimed at enhancing the quality of the higher educational product. However, the policy, while providing an accountability framework at the institution level, failed to provide the structural mechanisms needed to achieve quality in the teaching and learning the students receive, that is the sub‐faculty level. Other factors, such as the potential growth of non‐government resources in the form of more international students have perhaps a greater chance of improving the quality of teaching and learning within the faculties, because they provide both the funds and an incentive for more funds as a reward for implementing quality assurance within the teaching and learning function of universities.  相似文献
