Flow state in self-paced and externally-paced performance contexts: An examination of the flow model
ObjectivesKimiecik and Stein's (1992) flow model proposed that personal and situational factors affect the experience of flow. Singer, 1988, Singer, 2000 argued that different mental processes underlie self-initiated and reactive performances. The first purpose of this study was to examine main and interaction effects between imagery use and confidence on flow state in different performance contexts. The second purpose was to assess main and interaction effects between flow state, imagery, and confidence on self-paced service and externally-paced groundstroke performance in tennis.DesignThis field study used a repeated-measures design.MethodA pilot study was conducted to inform the set up of the two performance contexts. Flow states were assessed on two separate occasions, (a) for the service performance, and (b) for the groundstroke performance. A total of 60 junior tennis athletes completed imagery and confidence measures before the field test.ResultsA significant interaction between imagery and confidence was found for flow state in the groundstroke but not in the service task. No significant interaction effects were found for performance outcome. Flow state significantly predicted groundstroke performance, and imagery and confidence predicted service performance.ConclusionsThe examination of flow in different performance contexts is challenging. Imagery and confidence are central to the experience of flow. Flow state appeared to be more important for the externally-paced than self-paced task. The relationship between flow and performance is complex, which requires the conceptual expansion of Kimiecik and Stein's (1992) flow model. 相似文献

Biased attention and dysphoria: Manipulating selective attention reduces subsequent depressive symptoms 总被引:1,自引:0,他引:1
Selective attention for dysphoric stimuli has been observed in individuals with depression and those at risk for depression. To date, no studies have investigated the effects of directly manipulating selective attention for dysphoric stimuli on depressive symptoms. Mild to moderately depressed college students (N=34) were randomly assigned to complete 4 sessions of either attention training (AT) or no training (NT) during a two-week period. Participants completed self-reported assessments of depressive symptoms at baseline, post-training, and follow-up. Participants in the AT condition had a significantly greater decrease in depressive symptoms from baseline to follow-up than participants in the NT condition. This group difference was mediated by change in attention bias. Our findings suggest that biased attention may have a causal role in the maintenance of depressive symptoms. 相似文献

Tūsī, a thirteenth century logician writing in Arabic, uses two logical connectives to build up molecular propositions: ‘if-then’, and ‘either-or’. By referring to a dichotomous Tree, Tūsī shows how to choose the proper disjunction relative to the terms in the disjuncts. He also discusses the disjunctive propositions which follow from a conditional proposition 相似文献

Luciano Floridi presents Information Ethics (IE) as an alternative to traditional moral theories. IE consists of two tenets. First, reality can be interpreted at numerous, mutually consistent levels of abstraction, the highest of which is information. This level, unlike the others, applies to all of reality. Second, everything, insofar as it is an information object, has some degree of intrinsic value and hence moral dignity. I criticize IE, arguing that Floridi fails to show that the moral community should be expanded beyond beings capable of suffering or having preferences. Next, I look at Floridi’s extended case against consequentialism generally and utilitarianism in particular. I try to show that his criticisms are flawed. Third, I argue that, for the most part, it is not clear what IE’s practical implications are. I conclude with a critical discussion of the one area of information ethics, traditionally conceived, that Floridi has written about at length, privacy. 相似文献

This study explored the interrelated job search, unemployment, and coping literature (e.g., Leana & Feldman, 1990 ; McKee‐Ryan, Song, Wanberg, & Kinicki, 2005 ), in which the effects of age, length of unemployment, and coping behaviors on reemployment expectations were investigated. The study included unique demographics in which 65% were long‐term unemployed. Length of unemployment, networking comfort, and job search confidence were significant in a regression, and age was not. Regardless of age, reemployment expectations can be higher if the job seeker has higher levels of networking comfort and/or job search confidence or lower if they have been unemployed for a longer duration. 相似文献

Psychologists have increasingly employed dictionary-based text analysis to examine the language of leadership, as leadership is embedded in a web of negotiated meanings and contextual factors. This research seeks to embed leaders’ rhetorical influence in leader–follower relationships and identify contextual factors that explain the different patterns of effective versus ineffective leaders’ and charismatic versus non-charismatic leaders’ uses of action-oriented terms and negation terms in their inaugural speeches. By analyzing data of 30 U.S. presidents’ inaugural addresses, presidential election outcomes, and leadership styles, I found that effective leaders used action-oriented terms more frequently in their inaugural speeches than ineffective leaders only when follower participation was low, whereas charismatic leaders used negation terms more frequently in their inaugural speeches than non-charismatic leaders only when follower endorsement was low. These findings suggest that effective leaders are attuned to action-related situational cues whereas charismatic leaders are attuned to value-related situational cues. 相似文献

I examine the role of the burdens of judgement argument in Rawls's defence of the claim that liberalism cannot be based on a comprehensive doctrine. According to Rawls, the burdens of judgement make it very unlikely that most individuals can agree on anything more than a purely political morality. I argue that the argument does not succeed. I concentrate on the last three burdens which are specifically about problems of reaching normative agreement. Firstly, I argue that Rawls's claim that modern society inevitably gives rise to a diversity of values is not convincing since for every claim of divergence a counterclaim of convergence can be provided. Secondly, I provide examples of plausible agreement on partial comprehensive doctrines. Thirdly, I argue that liberalism must rely on at least one partial comprehensive doctrine, namely, the value of autonomous choice. I conclude that the burdens of judgement argument does not demonstrate that liberalism cannot be based on comprehensive moral foundations. 相似文献

In some situations, memory is enhanced by stressful experience, while in others, it is impaired. The specific components of the stress-response that may result in these differing effects remain unclear, and the current study sought to address this knowledge gap. Forty healthy participants (20 women, 20 men) were exposed to emotionally arousing and neutral pictures. Twenty-four hours later, 20 participants underwent a social stressor (speech and math tests), and 20 underwent a control reading task, both followed by a delayed free recall task. Cortisol responders to the stress condition (5 men and 1 woman) showed reduced memory retrieval for both neutral and emotionally arousing pictures. Men and women in the stress condition who did not produce a cortisol response showed increased retrieval of unpleasant pictures compared to controls. The results provide further evidence that cortisol is a primary effector in the stress-induced memory retrieval deficit. At the same time, stress can enhance memory retrieval performance, especially for emotional stimuli, when the cortisol response is absent. 相似文献
