This study provided a systematic qualitative examination of robust sport-confidence. A focus group (2 male and 2 female participants), and follow-up interviews, with 16 (8 male and 8 female participants) elite individual sport performers, were conducted to define and contextualize the characteristics of robust sport-confidence. Data analysis procedures resulted in a definition of robust sport-confidence and the identification of 6 characteristics of robust sport-confidence. The characteristics abstracted were: multidimensional, malleable, durable, strength of belief, developed, and protective. Overall, robust sport-confidence was conceptualized as a multidimensional set of enduring positive beliefs. Future research and practical implications are discussed. 相似文献

We examined the influence of stance width (the distance between the feet) on postural sway and visually induced motion sickness. Stance width influences the magnitude of body sway, and changes in sway precede the subjective symptoms of motion sickness. Thus, manipulation of stance width may influence motion sickness incidence. Participants (healthy young adults) were exposed to complex, low-frequency oscillation of a moving room. Participants stood with their feet 5 cm, 17 cm, or 30 cm apart. During exposure to visual motion, the widest stance (30 cm) was associated with reduced incidence of motion sickness. For all stance widths, motion sickness was preceded by significant changes in motion of the head and torso. The results support the postural instability theory of motion sickness and suggest practical implications for the prevention of motion sickness. Adoption of wider stance may decrease the risk of motion sickness in operational situations. 相似文献

The purpose of this study was to examine the relationships of perceived motivational climate to cohesion and collective efficacy in elite female teams. A total of 124 basketball and handball athletes completed two season measures (T1, T2). Relationships were examined at an individual level both statically and across time. Canonical correlations revealed that a combination of high perceptions of an ego-involving but low perceptions of a task-involving climate were associated with low perceptions of task cohesion at Time 1. High perceptions of a task-involving but low perceptions of an ego-involving climate were associated with higher perceptions of task cohesion and collective efficacy at Time 2. Moreover, low perceptions of an ego-involving and moderately low perceptions of a task-involving climate were associated with high perceptions of social cohesion at Time 2. Regression analyses including autoregressive influence indicated that a task-involving climate positively predicted variance in T2 group integration-task and collective efficacy after controlling for T1 scores. In contrast, an ego-involving climate negatively predicted changes in T2 athletes’ perceptions of social cohesion (individual attractions to the group-social [ATG-S], group integration-social [GI-S]) and group integration-task [GI-T] after controlling for T1 scores. Theoretical and practical implications are discussed. 相似文献

This study identified the sources and types of confidence salient to 14 (7 male, 7 female) successful World Class athletes. Nine sources of confidence were identified: Preparation, performance accomplishments, coaching, innate factors, social support, experience, competitive advantage, self-awareness, and trust. A testament to the multi-dimensional nature of sport confidence, six types of sport confidence were also identified: skill execution, achievement, physical factors, psychological factors, superiority to opposition, and tactical awareness. Gender was related to both the sources of confidence and the subsequent types of confidence experienced by the athletes. For example, females placed more importance on good personal performances than males who derived confidence from winning. Results were discussed in the context of previous sport confidence literature and implications for sport psychology and coaching practices were drawn. 相似文献

This study investigated temporal responses associated with competitive anxiety in athletes with facilitative and debilitative interpretations of their anxiety symptoms. Qualitative interviews assessed the intensity, frequency, and direction of cognitive and somatic symptoms experienced during a 7-day competitive cycle and the psychological strategies used to attain/maintain a positive psychological state. Analysis indicated three distinct temporal phases within the competitive cycle during which the intensity and frequency of cognitive and somatic symptoms increased. The facilitators utilized a refined repertoire of psychological skills to internally control and re-interpret the cognitive and somatic symptoms experienced. The debilitators did not possess this refined repertoire of psychological skills and relied on external strategies to stabilize the negative symptoms experienced. The findings emphasize the dynamic properties of the stress response and provide a framework for the structure, timing, and content of psychological skills interventions for use with performers who interpret anxiety symptoms as debilitative. 相似文献

The human visual system employs a sophisticated set of strategies for scanning the environment and directing attention to stimuli that can be expected given the context and a person’s past experience. Although these strategies enable us to navigate a very complex physical and social environment, they can also cause highly salient, but unexpected stimuli to go completely unnoticed. To examine the generality of this phenomenon, we conducted eight studies that included 15 different experimental conditions and 1,577 participants in all. These studies revealed that a large majority of participants do not report having seen a woman in the center of an urban scene who was photographed in midair as she was committing suicide. Despite seeing the scene repeatedly, 46 % of all participants failed to report seeing a central figure and only 4.8 % reported seeing a falling person. Frequency of noticing the suicidal woman was highest for participants who read a narrative priming story that increased the extent to which she was schematically congruent with the scene. In contrast to this robust effect of inattentional blindness, a majority of participants reported seeing other peripheral objects in the visual scene that were equally difficult to detect, yet more consistent with the scene. Follow-up qualitative analyses revealed that participants reported seeing many elements that were not actually present, but which could have been expected given the overall context of the scene. Together, these findings demonstrate the robustness of inattentional blindness and highlight the specificity with which different visual primes may increase noticing behavior. 相似文献

While even today lesbian, gay, bisexual and transgender people might have cause to distrust the healthcare establishment, how much more fragile was the relationship between sexual minorities and health professionals in the first decade of the AIDS epidemic. Dissent from consensus healthcare and health research then was a question of survival in the face of political and medical intransigence. This article focuses on one version of AIDS dissent: The narrative representations of AIDS in fiction by the gay African-American fantasy writer Samuel R. Delany, which rejected the rigid binarism of “safe” and “unsafe” sex practices, Delany’s evidence-based dissent. He also engaged in a related form of cultural dissent: speaking the unspeakably obscene, at a time when Silence?=?Death. Delany called into question both the inferential leaps based on limited epidemiological research that were represented in safer sex guidelines and the widespread public reticence about sexual behavior. 相似文献

We acknowledge the limitations in measures of moral reasoning and pursue an alternative technique by investigating past behaviors as they relate to present behavioral intentions. Our purpose is to evaluate the merits of patterned normative behavior for predicting present and future, morally relevant outcomes. Participants (N = 177) completed a policy capturing experimental design responding to questions that orthogonally varied the situational nature of the decision context. Results indicate that past normative behaviors are significantly and directly related to ethical behavioral intentions. Moreover, they moderate the relationships between situational factors and intended outcomes as well as moral reasoning and intended outcomes. 相似文献

Self-initiated action effects are often perceived as less intense than identical but externally generated stimuli. It is thought that forward models within the sensorimotor system pre-activate cortical representations of predicted action effects, reducing perceptual sensitivity and attenuating neural responses. As self-agency and predictability are seldom manipulated simultaneously in behavioral experiments, it is unclear if self-other differences depend on predictable action effect contingencies, or if both self- and externally generated stimuli are modulated similarly by predictability. We factorially combined variation in (1) predictability of action effects, (2) spatial congruence, and (3) performance by the self or computer to dissociate these influences on a visual discrimination task. Participants performed 2AFC speed judgments. Self-initiated motion was judged to be slower than computer-initiated motion when action effect contingencies were predictable, while spatial congruence influenced speed judgments only when action effect contingencies were unpredictable. Results are discussed in relation to current theories of sensory attenuation. 相似文献
