ObjectivesThis study examined the temporal characteristics of performing under pressure in a high-stakes real-world sport situation.DesignBehavior observation analyses were conducted of televised soccer games.MethodsVideos were obtained from all penalty shootouts ever held in three major international soccer tournaments (World Cup, European Championships, and UEFA Champions League). In these events, 296 players performed 366 penalty kicks. The time periods that were analyzed in relation to shot outcomes were: walking, ball placement, back-up, signal waiting, signal response, and run-up.ResultsSeveral time intervals were linked to performance. For example, longer times to respond to the referee's ready signal were related to more goals and shorter times were related to more misses. A similar weak trend was found for ball placement. Time to wait for the referee signal went in the other direction, with shorter times giving more goals.ConclusionsShorter self-imposed times were linked to worse performance than longer times. Plausible reasons for this result may be the extreme levels of pressure that are induced by major penalty shootouts, causing performers to attempt escaping the emotional distress by getting the situation “over with” as soon as possible. These results are consistent with a model of choking as a case of self-regulatory breakdown.  相似文献

Self-reported emotional experiences and eating behaviors were studied in college students in an attempt to determine what types of emotional experiences precede and follow binge eating and how specific types of compensatory behaviors modify these experiences. First-year male and female students (N=390) were surveyed for depression, anxiety, health status, life satisfaction, and eating attitudes (EAT-26). Those reporting recurrent binge eating episodes were asked to describe their emotional feelings before and after bingeing and before and after compensatory activities. EAT-26 scores corresponding to scores previously reported for eating disordered patients were found in 9.7% of students. Binge eating was nearly twice as frequent among females (16.4%) as males (8.6%) Among females, positive relationships were found between specific EAT-26 factors scores and both anxiety and depression scores. The emotional antecedents and consequences of binge eating and of compensatory activities were compared in three sub-groups of individuals who reported recurrent bingeing with loss of self-control during binges. The three sub-groups consisted of individuals who reported, 1) bingeing without engaging in compensatory activities, 2) bingeing and compensating by means other than vomiting (fasting, exercising, or use of laxatives or diuretics), and 3) bingeing and compensating by vomiting. Regardless of the type of activity, those individuals who engaged in compensatory activities reported greater negative affect preceding binge episodes than those who did not compensate. In addition, contrary to expectations, negative affect did not decrease, but instead increased significantly, following binge episodes and decreased immediately before and after compensatory activities.  相似文献

Christians in the developing world are sending a clear message to all who will listen: more attention needs to be paid to the Holy Spirit than ever before in the history of Christian thought. This essay explores what African Pentecostalism could teach Karl Barth and in particular how the actualistic Christology that Barth is known for can be applied to concrete acts of the Holy Spirit. The essay employs James Buckley's distinction between what Barth says versus what Barth shows to demonstrate profound possibilities that exist within Barth's thought for beginning theological reflection from the concrete acts of the Spirit.  相似文献

This study examined the links between historical team results and individual players' subsequent performances in a high-pressure real-world sport situation. Videos were obtained from all soccer penalty shootouts held in two major international tournaments (World Cup and European Championships) between 1976 and 2006 (n=260 players/309 kicks), and we controlled for team ability and country. The results showed that players on teams with preceding losses performed worse and generally took their shots more quickly than players on teams with preceding wins. These differences were also found with players who took no personal part in the preceding games. In conclusion, the results support the existence of historical dependency effects for performance on important and dramatic high-pressure tasks and they are in part consistent with a view of choking under pressure as a function of threatened egotism and self-regulation failure.  相似文献

In the present article, we extend the notion of cultural threat posed by immigrants beyond its current conceptualization as symbolic, collective‐level threats to American culture and identity. Instead, we argue that routine encounters with non‐English‐speaking immigrants cause many individuals to feel threatened because of real barriers to interpersonal communication and exchange. We draw upon survey and experimental data to demonstrate that local contact with immigrants who speak little to no English, as well as incidental exposure to the Spanish language, heighten feelings of cultural threat, which increases anti‐immigrant sentiment and policy preferences.  相似文献

In this discussion, I contrast Knafo’s worry about online inhumanity with a perspective informed by Katherine Hayles’s humanistic work on cybernetics, the posthuman, and the technological unconscious. Drawing upon my own writing about cyberobjects and reality, I argue that Knafo’s claim that “technology has invaded our intimate lives” is wildly overstated and that it hinges upon a curious manipulation of a false active/passive binary that is then used as a litmus test for perversion. I challenge Knafo’s “evolutionary” and materialist claims with reference to the intercourse of perversion and neoliberalism.  相似文献

ABSTRACT

Two experiments examined age differences in mechanisms hypothesized to affect activation of item and temporal information in working memory. Activation levels were inferred from the ability to reject n-back lures matching items in different temporal positions. Information with the least decay had a performance advantage over less recent information, but was susceptible to the same temporal context errors found in all adjacent-to-target lure positions. Lures most distant from the current item showed a performance rebound. The pattern of increased magnitudes of age effects at adjacent-to-target positions indicated a reduction in older adults' working memory for temporal context information above and beyond item memory declines. Results overall support the emphasis on context information as a critical factor in working memory and cognitive aging.  相似文献

ABSTRACT

Previous research has observed that the size of age differences in short-term memory (STM) depends on the type of material to be remembered, but has not identified the mechanism underlying this pattern. The current study focused on visual STM and examined the contribution of information load, as estimated by the rate of visual search, to STM for two types of stimuli – meaningful and abstract objects. Results demonstrated higher information load and lower STM for abstract objects. Age differences were greater for abstract than meaningful objects in visual search, but not in STM. Nevertheless, older adults demonstrated a decreased capacity in visual STM for meaningful objects. Furthermore, in support of Salthouse's processing speed theory, controlling for search rates eliminated all differences in STM related to object type and age. The overall pattern of findings suggests that STM for visual objects is dependent upon processing rate, regardless of age or object type.  相似文献

While much research shows the relationship between individual-level variables, such as Jewish background, education, age, and income and an individual’s Jewish identity, very little research has systematically addressed the question of community context, either general or Jewish, as a factor influencing Jewish religious or ethnic identity. This lack of research has been partially a result of the lack of an adequate data set to facilitate such analysis. Using the newly-aggregated Decade 2000 data set, with its 19,800 cases spread across 22 Jewish communities, we find that despite the anecdotal evidence and the logic that suggests that environment impacts behavior, the environmental impact on Jewish identity is clearly weak. Individual characteristics are much stronger than community context in explaining variations in the strength of Jewish identity.  相似文献
