The purpose of this investigation was to determine the role of cognition and mood in the performance of squash tasks, with particular reference to attention and self-reported arousal and stress. Volunteer male subjects (n = 40), divided into three ability groups, 'skilled', 'average' and 'novice', were required to perform two squash tasks with different degrees of difficulty. Order of presentation of the tasks was controlled. Results indicated that subjects completing the easier squash task first performed better on the subsequent difficult task than those subjects who completed the more difficult task first. No differences in scores across tasks were found for subjects completing the tasks in reverse order. Performance was related to level of skill. Furthermore, significant differences in attentional style were revealed when average subjects were compared with skilled and novice players. Skilled players were also found to exhibit significantly different personality characteristics from novice players. Specifically, skilled players exhibited higher levels of extraversion and appeared less neurotic. For the average and novice groups, reports of high levels of stress accompanied those of high levels of arousal and these remained constant throughout the experiment. By contrast, for the skilled group low levels of stress accompanied high levels of arousal. The results are discussed in terms of the effects of these cognitive and mood factors on performance and a suggested direction for future research is offered.  相似文献

Social loafing is the tendency of individuals to work less hard collectively than individually. The present study examined the joint influence of achievement motivation and expected coworker effort on collective task performance. Participants (N= 107) who qualified and were available after pretesting on an achievement motivation scale were randomly assigned to a work condition and coworker effort condition. Dyads were asked to generate as many uses for a knife as possible within a 12‐min time period. Participants low in achievement motivation engaged in social loafing, but only when expected coworker effort was high, whereas participants high in achievement motivation did not engage in social loafing, regardless of expected coworker effort. The implication of achievement motivation for collective task performance settings is discussed.  相似文献

The stigma of mental illness: Explanatory models and methods for change   总被引:4,自引:0,他引:4  
For people with mental illness, diminished quality of life and loss of personal goals does not result solely from the symptoms, distress, and disabilities caused by their psychiatric disorder. Quality of life and personal goals are also hindered by people who embrace the stigma that accompanies mental illness and mental health care. This paper reviews evidence of the impact of mental illness stigma and strategies for seeking to ease its impact. To achieve these goals, we (a) describe the ways in which stigma harm people with mental illness, (b) summarize models that explain the development and maintenance of these stigmatizing effects, and (c) review strategies that have been shown to decrease the impact of stigma. Concerns about stigma are on the political agendas of many mental health advocacy groups. It has recently also become the focus of extensive research. Our goal in this paper is to balance the practical concerns raised by mental health advocates against data that support or contradicts specific assertions.  相似文献

This study examined the use of punitive coaching strategies in youth sport and the nature of these experiences for youth athletes. Semistructured interviews and concept maps were conducted with 12 competitive male and female hockey athletes 11–13 years of age. Data were analyzed using inductive thematic analysis. Results revealed that punishments occurred in competitive youth hockey, in the forms of benching, yelling, exercises, cleaning up equipment, and alternating positions. Findings are interpreted to suggest that punishments hindered developmental needs of youth athletes, including a positive sense of self and positive relationships with others. Implications for healthy youth development are discussed.  相似文献

Modeling homophily over time with an actor-partner interdependence model   总被引:1,自引:0,他引:1  
Selection and socialization have been implicated in friendship homophily, but the relative contributions of each are difficult to measure simultaneously because of the nonindependent nature of the data. To address this problem, the authors applied a multiple-groups longitudinal actor-partner interdependence model (D. A. Kashy & D. A. Kenny, 2000) for distinguishable dyads to 3 consecutive years of intoxication frequency data from a large community-based sample of Swedish youth. Participants, ranging from 12 to 18 years old (M = 14.35, SD = 1.56) at the start of the study, included 902 adolescents (426 girls and 476 boys) with at least one reciprocated friend during at least one time point and 212 adolescents (84 girls and 128 boys) without reciprocated friends at any time. Similarity estimates indicated strong effects for selection and socialization in friends' intoxication frequency. Over time, younger members of these dyads had less stable patterns of intoxication than older members, largely because younger partners changed their drinking behavior to resemble that of older partners.  相似文献

In a sample of 206 boys (90% Caucasian), self-reported suicidal ideation (SI; ages 12 to 29) and parent-reported youth suicidal talk (ages 9 to 20) were assessed annually by questionnaire. One-week point prevalence of self-reported SI ranged from 2.6% to 16.3%. New cases emerged across adolescence; by age 29, 57.3% self-reported SI at least once. SI was associated with clinically significant elevations on concurrent depressive symptoms. Nearly one quarter (24.8%) of parents reported suicidal talk by their son by age 20. Parent- and self-reports showed low correspondence. SI was more common than retrospective studies suggest. Parent-reports and one-time self-reports are likely to miss large numbers of adolescent boys who may be at risk.  相似文献
