In this commentary, we react to the recent study by Helsen, Gilis and Weston (2006) on judging offside in football. Helsen et al. claim that their data falsify the optical error hypothesis presented by Oudejans et al. (2000). However, as we will elucidate here, they misinterpret this hypothesis and present a data set that is seriously flawed, and hence not suited to test it. Therefore, their conclusions regarding the optical error hypothesis are in error. 相似文献

The mastery approach to coaching is a cognitive-behavioral intervention designed to promote a mastery-involving motivational climate, shown in previous research to be related to lower anxiety in athletes. We tested the effects of this intervention on motivational climate and on changes in male and female athletes'cognitive and somatic performance anxiety over the course of a basketball season. Hierarchical linear modeling analyses revealed that the athletes in the intervention condition perceived their coaches as being more mastery-involving on the Motivational Climate Scale for Youth Sports when compared to athletes in an untreated control condition. Relative to athletes who played for untrained coaches, those who played for the trained coaches exhibited decreases on all subscales of the Sport Anxiety Scale-2 and on total anxiety score from preseason to late season. Control group athletes reported increases in anxiety over the season. The intervention had equally positive effects on boys and girls teams. 相似文献

Since their beginnings pre-election polls have been under attackfrom politicians and journalists. One of the most fundamentalcriticisms of polls is that they can influence the outcome ofelections. This article investigates news media reporting ofpoll results and comments on public opinion research beforeFederal elections in Germany. It presents empirical findingsfor the quantity as well as the formal and substantial qualityof this press coverage. The database is a content analysis of443 pre-election poll articles published in Germany's leadingdailies Frankfurter Allgemeine Zeitung (FAZ), Frankfurter Rundschau(FR), Süddeutsche Zeitung (SZ), and Die Welt (Welt) between1980 and 1994. The quantity of news media reporting of publicopinion polls has improved over the years. Now, poll storiesare a standard feature of German newspapers. The frequency ofreports depends on the conditions of each election—e.g.on the expected closeness of the election outcome. The formalquality could be better—that is the conformity to AAPORstandards. Horse-race journalism isn't found as often as inthe USA. Journalists often use poll results to predict an electionoutcome. Moreover, the analysis revealed an ambivalent relationshipbetween liberal journalists and polls, while the reporting ofconservative journalists is more in favor of opinion research. 相似文献
