This study investigated the link between physical self-presentation and competitive anxiety in male, master-level, high-board divers (N=84, M age = 29.3 yr., SD = 14.3). Competitive trait anxiety, social physique anxiety, and physical self-presentation confidence were assessed using the Sport Anxiety Scale, Social Physique Anxiety Scale, and the Physical Self-presentation inventory. Stepwise regression analyses indicated that variance in competitive anxiety was accounted for by the physical self-presentation variables and that these variables were more strongly associated with the cognitive anxiety subscale Worry, and to a lesser extent, Somatic Anxiety. The results of this study provide support for the argument that physical self-presentation is associated with competitive anxiety in male athletes. 相似文献

Yes we can! is a community-building initiative funded by the W. K. Kellogg Foundation that aims to improve educational and economic outcomes in Battle Creek, Michigan by mobilizing low-income communities and resident leaders and building their capacity to influence the decisions and policies that impact their lives. This paper describes the strategies pursued during the first phase of this initiative to foster resident mobilization by building small wins within the neighborhood. Primarily through a neighborhood-based mini-grant program and staff supports to encourage collective action, Yes we can! has started to increase levels of resident mobilization within the seven economically distressed neighborhoods that initially partnered with the W. K. Kellogg Foundation on this effort. The specific programming components and how they were implemented as well as the initial successes experienced are described. Lessons learned are discussed. 相似文献

People who score low on a performance test overestimate their own performance relative to others, whereas high scorers slightly underestimate their own performance. J. Kruger and D. Dunning (1999) attributed these asymmetric errors to differences in metacognitive skill. A replication study showed no evidence for mediation effects for any of several candidate variables. Asymmetric errors were expected because of statistical regression and the general better-than-average (BTA) heuristic. Consistent with this parsimonious model, errors were no longer asymmetric when either regression or the BTA effect was statistically removed. In fact, high rather than low performers were more error prone in that they were more likely to neglect their own estimates of the performance of others when predicting how they themselves performed relative to the group. 相似文献

The nonconsciousness of self-consciousness 总被引:2,自引:0,他引:2
Hull JG Slone LB Meteyer KB Matthews AR 《Journal of personality and social psychology》2002,83(2):406-424
Five studies demonstrated that private self-consciousness is associated with nonconscious, automatic behaviors. In 2 studies, high but not low self-conscious individuals walked more slowly following exposure to an implicit elderly prime. In a 3rd study, high but not low self-conscious individuals showed improved performance following exposure to a subliminal success prime relative to a subliminal failure prime. In a 4th study, subliminal exposure to an angry prime was shown to increase blood pressure relative to a relax prime. In a final study, the latter effect was shown to be true only for high self-conscious individuals and only for subliminal presentations. Results are discussed in terms of their implications for understanding a variety of effects associated with self-consciousness and self-awareness. 相似文献

It feels like yesterday: self-esteem,valence of personal past experiences,and judgments of subjective distance 总被引:5,自引:0,他引:5
Supporting predictions from temporal self-appraisal theory, participants in 3 studies reported feeling farther from former selves and experiences with unfavorable implications for their current self-view than from equally distant selves and experiences with flattering implications. This distancing bias occurred when assignment to negative and positive pasts was random, for both achievement and social outcomes and for single episodes as well as longer term experiences. Consistent with a motivational interpretation, the distancing bias was stronger among high than low self-esteem participants and occurred for personal but not for acquaintances' past events. Frequency of rehearsal and ease of recall of past episodes also predicted feelings of distance, but these variables did not account for the Self-Esteem x Valence interaction on subjective distancing of personal events. 相似文献

The present experiment assessed the effects of cocaine on the lever pressing of 4 rats maintained during 15-min sessions by a fixed-ratio 50 schedule of food reinforcement. Across phases, supplemental food was provided either immediately or 2 hr after sessions. Two rats began the experiment in the delayed-feeding condition, and 2 began the experiment in the immediate-feeding condition. Rates of lever pressing of 2 rats sometimes decreased to low levels near the ends of sessions when supplemental feeding was provided immediately, but were consistently high throughout sessions when supplemental feeding was delayed. Cocaine (1.0 to 17.0 or 30.0 mg/kg) was administered intraperitoneally 15 min prior to test sessions. In most cases, cocaine suppressed response rates at lower doses under immediate-feeding conditions. Decreases in overall response rates were correlated with dosedependent increases in the time rats spent not responding. It is suggested that delaying the time of postsession feeding increased response strength, as indicated by greater resistance to the rate-suppressive effects of cocaine. 相似文献

In this comment on E. T. Gershoff (2002), the author notes the historical phases of punishment research. Punishment as a disciplinary tactic is best viewed as a packaged variable and therefore needs to be investigated in the context of other socialization practices. The role of parental values in this debate about punishment utilization and effectiveness merits more consideration. New directions in punishment research are also noted. These include the need for a family-systems perspective, a family-typology approach, a transactional model of punishment, the use of innovation observation and self-report methods, and more culturally sensitive paradigms. 相似文献

We examined the contribution of semantics to morphological facilitation in the visual lexical decision task at two stimulus onset asynchronies (SOAs) with Serbian materials. Primes appeared in Roman or Cyrillic characters. Targets always were printed in Roman. When primes were presented at an SOA of 250 msec, decision latencies to verbal targets (e.g., VOLIM) showed greatest facilitation after inflectionally (e.g., VOLE) related primes, significantly less after semantically transparent derived primes (e.g., ZAVOLE), and less again after semantically opaque derived primes (e.g., PREVOLE). Latencies after semantically transparent and opaque derived target words did not differ at an SOA of 48 msec. Both were slower than after inflectionally related primes. Stated generally, effects of semantic transparency among derivationally related verb forms were evident at long SOAs, but not at short ones. Under alphabet-alternating conditions, magnitudes of facilitation were greater overall, but the pattern was similar. The outcome suggests that restricted processing time for the prime limits the contribution of semantics to morphological processing and calls into question accounts that posit a task-invariant semantic criterion for morphological decomposition within the lexicon. 相似文献

Learning abstract relations from using categories 总被引:4,自引:0,他引:4
When people learn categories, the importance of the features and relations in the category representation reflects both their diagnosticity for classification and their relevance to the use of the category. In earlier work in which the influence of category use on the representation has been shown, only cases in which the features and relations were simple, observable, and very specific were examined. Learners may begin to understand the underlying similarities of category members by using the categories. In the four experiments presented here, learners applied a simple category-specific formula to category members. The test results showed that the learners had incorporated relations among features from this use, including cases in which the relations were abstract. This learning occurred even though the relations were actually not predictive of category membership but just perceived to be so as a function of the use. 相似文献

People often learn multiple classification systems that are relevant to some goal or use. We compared conditions in which subclassification within a category hierarchy was predicted by values on either the same (alignable) or different (nonalignable) dimensions between category hierarchies. The results indicated that learning in alignable conditions occurred in fewer blocks and with fewer errors than did learning in nonalignable conditions. This facilitation was not the result of differences between conditions in the representations learned by the participants, the number of dimensions needed for subclassification (Experiment 1), or the objective complexity of the learning task (Experiment 2). The facilitated learning in the alignable conditions appears to reflect a commitment on the part of the learner to alignment: the belief that the structure relevant to the use of one category system will also be relevant to the use of a comparable system. 相似文献
