Arousal, anxiety, and performance: a reexamination of the Inverted-U hypothesis     

Arent SM  Landers DM 《Research quarterly for exercise and sport》2003,74(4):436-444

Until recently, the traditional Inverted-U hypothesis had been the primary model used by sport psychologists to describe the arousal-performance relationship. However, many sport psychology researchers have challenged this relationship, and the current trend is a shift toward a more "multidimensional" view of arousal-anxiety and its effects on performance. In the current study, 104 college-age participants performed a simple response time task while riding a bicycle ergometer. Participants were randomly assigned to one of eight arousal groups (between 20 and 90% of heart rate reserve) and were told they were competing for a cash prize. Prior to the task, the Competitive State Anxiety Inventory-2 and Sport Anxiety Scale (SAS) were administered to assess the influence of cognitive and somatic anxiety. As hypothesized, regression analysis revealed a significant quadratic trend for arousal and reaction time. This accounted for 13.2% of the variance, F change (1, 101) = 15.10, p < .001, in performance beyond that accounted for by the nonsignificant linear trend. As predicted by the Inverted-U hypothesis, optimal performance on the simple task was seen at 60 and 70% of maximum arousal. Furthermore, for the simple task used in this study, only somatic anxiety as measured by the SAS accounted for significant variance in performance beyond that accounted for by arousal alone. These findings support predictions of the Inverted-U hypothesis and raise doubts about the utility theories that rely on differentiation of cognitive and somatic anxiety to predict performance on simple tasks that are not cognitively loaded.  相似文献

Validation of a stages of exercise change questionnaire     

Dannecker EA  Hausenblas HA  Connaughton DP  Lovins TR 《Research quarterly for exercise and sport》2003,74(3):236-247

The purpose of this study was to examine evidence for the validity of a stages of change measure of the Transtheoretical Model for exercise behavior. Participants were 152 university students (53.3% women, 71.6% Caucasian, M age = 19.18 years) who completed processes of change, self-efficacy, decisional balance, stages of change, and exercise behavior questionnaires as well as a maximal treadmill test. Participants in the action and maintenance stages had the highest strenuous (PC/C/P < A/M) and moderate (PC/C < A/M) self-reported exercise behavior. Those in the maintenance stage had the highest estimated aerobic fitness (PC/P < MA). The differences between the early stages (PC, C, and P) and the later stages (A and M) as described by the first function were primarily due to the behavioral process of change. The differences between the extreme stages (PC and M) and the middle stages (C, P, and A) were due to the experiential processes of change and the pros of decisional balance. The hypothesized patterns of stage differences were partially supported. Failure to obtain full support may have been due to methodological issues or inherent difficulties in detecting evidence for the validity of stages of change measures.  相似文献

Listening to our Students: Understanding the factors that affect Aboriginal and Torres Strait Islander students' academic success     

Kristie Daniel DiGregorio  Sally Farrington  Susan Page 《高等教育研究与发展》2000,19(3):297-309

While the number of Aboriginal and Torres Strait Islander students in higher education in Australia has doubled in recent years, the gap between their attainment and the attainment of other Australians has remained consistent. It is essential to elucidate the factors that promote Aboriginal and Torres Strait Islander students' academic success, not in order to justify the exclusion of these students from tertiary education, but to refine and develop curriculum and management strategies which promote their academic success. This study focuses on Aboriginal and Torres Straight Islander students' experiences in a diploma program offered in block mode, in order to better understand the ‘on-’ and ‘off-’ campus experiences which are related to academic success and the factors which challenge or enhance students' study. The research yields important findings related to students' motivations to enrol and their definitions of academic success; the challenges they experience in making the transition to tertiary study; the vulnerability of our students' determination to succeed; the effects of being in a program for Aboriginal and Torres Strait Islander students; and the ways in which minor challenges, if unresolved, can accumulate to interfere with students' study.  相似文献   

“Damn'd . . . & beat at rehearsal”: The character James Quin's stage management     

Daniel W. Alkofer 《Communication Studies》2013,64(3):152-157

Quin deserves recognition as a stage manager in Londons patent theatres between 1725 and 1751 because he compensated for John Rich's indifference to legitimate plays and for Charles Fleetwood's gentlemanly incompetence. As in his acting, Quin was adamantly dedicated to maintaining the established Augustan ideal.  相似文献
