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

ObjectivesIt has been suggested that hastening and hiding—rushing through penalty preparation and not looking at the goal when preparing the penalty kick—are associated with negative penalty taking performance. In the present study, we investigated how opposing players perceived these nonverbal behaviors, how they affect outcome expectations, and how they affect the behavior of opposing goalkeepers.DesignThe present study employs an experimental research design (Experiment 1: 2 (gaze behavior) × 3 (preparation time) design; Experiment 2: 2 (gaze behavior) × 2 (preparation time) design).MethodWe examined the perception of nonverbal hastening and hiding behavior using the point-light technique during the soccer penalty kick among goalkeepers (Experiment 1a; n = 20), and among outfield soccer players (Experiment 1b; n = 29). Furthermore, we analyzed how these respective penalty preparation strategies influenced the behavior of high-level goalkeepers (n = 12) under in situ conditions (Experiment 2).ResultsThe results from Experiment 1 demonstrated that penalty takers showing hastening and hiding behaviors are perceived more negatively by both soccer goalkeepers and outfield players: (i) they are considered to possess less positive attributes, (ii) to have less accuracy in their penalties, and (iii) likely to perform less well in penalty situations. Experiment 2 provided first evidence that goalkeepers initiate their movement later following the observation of hastening and hiding behaviors during the penalty preparation.ConclusionsOur findings demonstrate the importance of investigating nonverbal behavior in sports as these have a major impact on impression formation, expected performance, and actual behavior of opposing players in the soccer penalty situation.  相似文献

ObjectiveThis study aims to test the effectiveness of a perceptual training concerning the anticipatory skills of soccer goalkeepers, by assessing their performances while engaged in predicting the direction of penalty kicks.DesignForty-two skilled goalkeepers were randomly assigned to three training groups: Experimental, placebo, and control. All the groups were tested at the beginning of the experiment and re-tested after a period of eight weeks.MethodThe pre-test consisted of the presentation of temporally occluded videos of penalties recorded from the goalkeeper's perspective, and participants had to predict the direction of the ball. The experimental group practiced with an interactive home-training, based on video analogous to those of the test, with the addition of both positive and negative feedback. The placebo group viewed television footage of penalty kick shoot-outs. Participants of both groups were free to schedule their own training/placebo sessions. Finally, the control group did not receive any treatment.ResultsThe results demonstrated the effectiveness of the home-training protocol, evidencing significant accuracy improvements between pre-test and post-test only for the experimental group.ConclusionsThe outcomes indicate that skilled athletes can benefit from perceptual training, which was not investigated before among soccer goalkeepers. Indeed, all the previous training studies concerning soccer penalty predictions were run on participants with either recreational or no goalkeeping experience at all. Moreover, the present training protocol is innovative because learners can schedule training sessions on their own. Finally, its usability suggests numerous potential applications.  相似文献

ObjectiveSmall-sided conditioned games (SSCG) in soccer are games with a small number of players, often played on smaller than regular pitches and with adapted rules. It has been argued that SSCG foster soccer players’ physical, technical and tactical performances and creativity. This study tested the latter conjecture by analysing video-footage of individual actions of elite soccer players in 5 v 5, 6 v 6, 7 v 7 SSCG played during regular training sessions and 11-aside training matches. Based on the ecological dynamics approach, we hypothesized that smaller formats would result in players making more individual actions. We additionally anticipated that the smaller formats players would induce a larger repertoire of actions, that is, an increased variability of actions, and that such increase in variability would be associated with more creative actions. Along the same lines, we reasoned that midfielders would make more creative actions than defenders and attackers.MethodWe categorized 3555 soccer actions on the ball and without the ball of 24 elite soccer players.ResultsPlayers produced more actions in smaller SSCG formats compared to the larger SSCG format and the 11-aside match. They also produced more different actions in SSCG than the 11-aside match. Furthermore, ten creative actions (i.e., actions that were adequate and only made by one or two players) were discerned. The creative actions emerged most often in the smaller SSCG, and were absent in the 11-aside matches. Finally, strikers, defenders and midfielders did not show reliable differences in terms of number, variability and creativity of action.ConclusionSSCG in soccer do indeed stimulate variability and creativity of individual actions. It is important to confirm whether these immediate effects of SSCG generalize across longer time scales.  相似文献

ObjectiveIt is well-established that early visual information has an important role in human ability to play ball sports, as its correct interpretation promotes accurate predictions concerning the ball motion. Other research highlights that auditory information provides relevant cues in various sport situations. The present study combines these two lines of research with the aim to investigate the contribution of early auditory and visual information to the discrimination of shot power in sport-specific situations.DesignTwo experiments were run, one concerning soccer penalty kicks and the other concerning volleyball smashes. In both experiments there were three conditions: Audio, Audiovideo, and Video; a within subjects design was used, with the three conditions carried out in three different days and in a counterbalanced order among participants.MethodParticipants’ task was to discriminate the power of two penalties/smashes presented in rapid sequence, on the basis of a two-alternative forced choice paradigm.ResultsThe results revealed that, for both penalties and smashes, response accuracy was above chance level in all the three conditions; moreover, while for the penalties no difference among the conditions was observed, for the smashes participants were more accurate in the Audio and Audiovideo conditions compared to the Video condition. As concerns the response times, for both penalties and smashes participants were faster in the Audio and Audiovideo conditions compared to the Video condition.ConclusionsTaken together, the results suggest that the discrimination of shot power was more easily performed on the basis of early auditory information than on the basis of the respective visual information.  相似文献

Quiet-eye training for soccer penalty kicks   总被引:1,自引:0,他引:1  
Anxiety has been shown to disrupt visual attention, visuomotor control and subsequent shot location in soccer penalty kicks. However, optimal visual attention has been trained in other far aiming skills, improving performance and resistance to pressure. We therefore asked a team of ten university soccer players to follow a quiet eye (QE; Vickers 1996) training program, designed to align gaze with aiming intention to optimal scoring zones, over a 7-week period. Performance and gaze parameters were compared to a placebo group (ten players) who received no instruction, but practiced the same number of penalty kicks over the same time frame. Results from a retention test indicated that the QE-trained group had more effective visual attentional control, were significantly more accurate, and had 50% fewer shots saved by the goalkeeper than the placebo group. Both groups then competed in a penalty shootout to explore the influence of anxiety on attentional control and shooting accuracy. Under the pressure of the shootout, the QE-trained group failed to maintain their accuracy advantage, despite maintaining more distal aiming fixations of longer duration. The results therefore provide only partial support for the effectiveness of brief QE training interventions for experienced performers.  相似文献

The effect of explicitly providing goalkeeper's movement advanced cue to the kicker during a real penalty kick task was assessed. 32 expert soccer players (M age= 23.2 yr.), who were divided into four groups: an experimental group, a discovery group, a placebo group, and a control group, participated. Rate of success in the task was assessed, as well as goals, decision times, and ball flight times. Providing an advance cue significantly improved the players' rate of success relative to players without the advance cue; this difference was still present after 1 and 7 days without training. The experimental group adapted better to the time range within which the response could be effective, while the discovery group showed adaptations. Explicit instructions about the advance cues available from goalkeepers' actions before the dive during practice can improve penalty kick performance.  相似文献

In a field study, we conducted a soccer penalty experiment in which players had to detect the goalkeeper's movement during the run-up. We tested subjects under two conditions: the center-looking (perceiving both stimuli peripherally) and the free gaze strategy (foveal gaze on either the ball or the goalkeeper, or saccades). The center-looking strategy was superior when it came to detecting goalkeeper movements; with respect to the number of scored goals, no difference could be detected. Future research should investigate whether appropriate training in the use of the center-looking strategy might lead to a higher number of scored goals.  相似文献

ObjectivesThe ability to make decisions under time pressure is crucial to performance in sport. However, there remains a paucity of research that examines whether the skills underpinning decision-making transfer across similar or dissimilar sports. We examine whether decision making transfers from soccer to other sports that may be deemed to be either similar (basketball) or dissimilar (tennis) based on sports taxonomy.MethodsSkilled soccer players (N = 20) completed a video-based temporal occlusion test designed to measure decision-making involving offensive sequences of play from soccer, basketball, and tennis. Participants were required to decide on an appropriate action to execute for each situation presented.ResultsResponse accuracy was higher in the soccer decision-making task compared to the basketball and tennis tasks. Furthermore, accuracy scores were higher on the basketball compared to the tennis task.ConclusionsThere appears to be some positive transfer of decision-making between sports that share similar elements, supporting the importance both of specificity and generality in expert performance.  相似文献

ABSTRACT. The authors’ aim was to investigate the speed-accuracy tradeoff in soccer kicking with the dominant and nondominant foot by using different types of instructions prioritizing speed or accuracy in experienced soccer players. Ten male soccer players were randomly given 1 of the 4 instructions that differed in aspects of the kick they should emphasize and what the secondary aim would be (speed or accuracy). It was found that ball velocity was affected by instruction in the expected way: emphasis on accuracy and ball velocity reduced for both kicking feet. In addition kicking accuracy increased when emphasizing this, but only with the dominant foot indicating that Fitts’ law only was found in kicks with the dominant foot.  相似文献

ObjectivesAlthough sports team members often value their teams highly, they sometimes make mistakes and thereby unintentionally put their teams at a disadvantage. Thus, they should be motivated to compensate for their mistake to resolve this discrepancy. To test this hypothesis, we studied whether professional soccer players compensate for their own goals by scoring regular goals in the same game (Study 1) and possible processes underlying such compensation efforts (Study 2).DesignIn Study 1, we compared how frequently prior own goal scorers scored a regular goal in the same game to (a) their expected goal scoring frequencies and (b) their probabilities to score a regular goal following a regular goal by the opposing team. In Study 2, we investigated four possible processes underlying the expected compensatory efforts.MethodWe analyzed all own goals from the first fifty years of the German Bundesliga (N = 889) and possible ensuing regular goals by the own goal scorer. Moreover, we surveyed amateur soccer players about four motives: group performance, individual performance, individual public image, and group public image.ResultsFollowing their own goals, professional soccer players are particularly likely to score regular goals in the same game (i.e., a compensatory own goal effect). Presumably, they primarily do so to secure a good group performance, but the other motives also play a role.ConclusionsGroup members who make highly visible mistakes are motivated to compensate for the disadvantage they caused. Presumably, they mainly do so to secure a good team performance.  相似文献

Male goalkeepers of intermediate skill level attempted to stop penalty kicks executed with the instep and inside foot, in situ. A mobile eye tracker and an external camera were used to collect the gaze and motor behaviors of the goalkeepers, as well as the penalty takers’ motor behaviors and flight of the ball. Percent saves was greater during instep (28%) than inside foot kicks (12%), but we detected few differences in fixation frequency, location, duration, or transitions that could be attributed to the type of kick used. Fixation transitions (or the frequency of gaze shifts between locations) were significantly higher on goals than on saves. During the final phase of the kicking action, the quiet eye was located on the visual pivot and was longer during saves than goals. Furthermore, when the final fixation on the ball exceeded approximately 1,100 ms, then the likelihood of goals increased. The results are discussed in light of past studies in goaltending and the dual demands of motor tasks that require information be fixated both early and late at spatial locations that exceed the limits of focal vision.  相似文献

Only few studies have addressed how soccer goalkeepers adapt to both the spatial and temporal constraints while trying to stop a penalty kick. Moreover, research on penalty kicks has only involved male goalkeepers, even though the resultant constraint (i.e., the relation between the maximum action capabilities defining the time required and ball flight time and direction defining the time available) may or may not differ for female goalkeepers. We therefore compared penalty goalkeeping between male and female goalkeepers of similar skill level. The results showed that the resultant constraint was more stringent for female than male goalkeepers. In accordance with the affordance-based control theory, female and male goalkeepers both adapted to the resultant constraint, but did scale their diving action differently. Female goalkeepers initiated the lateral dive within the action boundaries set by the resultant constraint, while male goalkeepers tended to dive late, beyond the action boundaries. Owing to the early dive, female goalkeepers saved more penalties than male in non-deceptive penalties. Nevertheless, female goalkeepers were also more susceptible to deception by the penalty taker than male goalkeepers. These findings extend our knowledge of the affordance-based control theory in sports and contribute to the understanding of gender differences in soccer penalty goalkeeping.  相似文献

Traditionally, goalkeeping in the soccer penalty kick has been studied using video-based technology, in which goalkeepers watched video footage of penalty kicks and indicated perceived ball direction. By omitting the requirement to actually dive or jump to the ball, these studies overlooked how action capabilities constrain goalkeepers' actions. By contrast, we examined whether goalkeeping in the penalty kick is consistent with affordance-based control, that is, whether goalkeepers guide their dive by taking into account their action capabilities (i.e., the time they need to intercept the ball).To this end, high- and moderate-skilled goalkeepers faced in-situ penalty kicks. Time constraints were manipulated by varying the kicking distance and the kicker's run-up speed. The results showed that goalkeepers of both skills level scaled the lateral dive onset to their action capabilities, but high-skilled goalkeepers acted closer to their maximum action boundary. In doing so, goalkeepers did not take the varying time constraints into account. Instead, high-skilled goalkeepers acted consistent with a strategy in which they coordinated the onset of the dive with the landing of kicker's non-kicking leg next to the ball.Consequently, we only find partial support for affordance-based control. We propose that this is explained by reliable information becoming available (too) late within the spatiotemporal constraints of the penalty kick.  相似文献

ObjectivesTwo studies examined the relationship between explanatory style measured with the Attributional Style Questionnaire (ASQ), Peterson, Semmel, von Baeyer, Abramson, Metalsky, and Seligman (1982. The Attributional Style Questionnaire. Cognitive Therapy and Research, 6, 287–299) and athletic performance.DesignCorrelational designs were used to examine relationships between the predictor variables of attributional style and dispositional optimism and the criterion variable of athletic performance. Study one also examined the effect of soccer match outcome as a moderational factor.MethodFor study 1, 20 male soccer players completed the ASQ and their performance across eight matches was videotaped and coded on a variety of measures (goals, fouls, attempted passes, completed passes). For study 2, 18 female basketball players completed both the ASQ and the Life Orientation Test (LOT), Scheier and Carver (1978. Optimism, coping and health: Assessment and implications of generalized outcome expectancies. Health Psychology, 4, 219–247). Relationships between these scales and a variety of performance measures were examined.ResultsConsistent with findings from Seligman, Nolen-Hoeksema, Thornton, N., and Thornton, K. (1990. Explanatory style as a mechanism of disappointing athletic performance. Psychological Science, 1, 143–146), a significant positive relationship was found between the ASQ measure of optimism and athletic performance among the soccer players in study 1. In addition, optimistic soccer players demonstrated better performance during a loss than did pessimists, whereas no significant performance differences were found between these two groups during a subsequent win. Findings from study 2 were less consistent, revealing both positive (optimists had more assists and steals) and negative (optimists had fewer rebounds and more fouls) relationships. A subsequent content analysis of the open-ended responses on the ASQ suggests that the observed negative relationships were a function of these female athletes attributing negative outcomes to lack of effort (defensive pessimism) as opposed to lack of ability (depressive pessimism).ConclusionsThe findings highlight the need to differentiate between these two forms of pessimism and their differential impact on performance. The importance of including an assessment of perceived controllability as an attributional dimension in future research is discussed.  相似文献

Attackers are supposed to take advantage of producing deceptive actions in competitive ball sports, particularly in penalty situations. We conducted a scoping review of the experimental literature to scrutinize whether penalty takers do indeed benefit from using deceptive actions in penalty situations, especially by increasing the likelihood to score a goal. Studies using video-based and in-situ tasks in which soccer and handball goalkeepers try to save a penalty were evaluated. Results showed that penalty takers' manipulation of spatial information available to the goalkeeper during deception (i.e., by using misleading and/or disguising actions) is less effective in in-situ than video-based studies. We argue that this difference occurs because goalkeepers adapt differently to the spatiotemporal constraints in the video-based and in-situ tasks. Goalkeepers appear to prioritize picking up spatial information in video-based tasks while prioritizing temporal information in-situ tasks. Therefore, the manipulation of spatial information appears to be less effective in the more representative in-situ studies than in video-based studies. In order to deceive, penalty takers are advised to manipulate temporal information during on-field penalty situations.  相似文献

Abstract

Many sport psychologists have been fighting against the pervasive “winning is everything” mentality and have encouraged athletes to set only self-referenced performance and process goals. However, studies that have explored the practices of successful performers have found that they do in fact make effective use of outcome goals (Weinberg, Burton, Yukelson, & Weigand, 1993; Jones & Hanton, 1996). The aim of this study was to examine empirically Hardy, Jones, and Gould's (1996) suggestion, that consultants should now be promoting the use of a multiple-goal strategy. Forty participants were split into five groups of equal number and matched for ability on a soccer task. Four of the groups used different combinations of outcome, performance, and process goals while the other acted as a control group. Performance on the soccer task was measured over a 5-week training period, and then in a competition. Two-factor (Group X Test) ANOVA's indicated significant differences (p < .05) between the groups for both training and competition performance. The superior performance of the groups using multiple-goal strategies provided evidence to support the efficacy of maintaining a balance between the use of outcome, performance, and process goals.  相似文献

This study investigates the efficacy of intermediate penalty kickers by comparing the effect of applying an automated WiFi system on the field of play to simulate a strategy that takes account of goalkeeper action (dependent) with another for which goalkeeper strategy is irrelevant (independent). Intermediate penalty kickers (n=12) took a pretreatment test of 32 kicks in a "real-play" situation with intermediate goalkeepers (n=3). Two groups of kickers underwent 11 treatment sessions using different strategies and then were administered a posttreatment test. The variables measured were the number of goals scored, whether the direction of the shot was the same or different from the direction of the goalkeeper's move (DDG), ball speed, and the duration of the kicking movement. Data suggested the goalkeepers had a greater capacity to identify advance cues when faced with independent strategy kickers and that dependent strategy kickers achieved lower ball speeds.  相似文献

ObjectivesContextual factors can influence the way sports officials apply unambiguous rules. The aim of this study was to better understand the leg-before-wicket (LBW) decision-making behaviour of elite cricket umpires and determine whether their behaviour changes according to the format of the game in which they are adjudicating.MethodsLBW decisions (n = 5578) from actual elite level cricket matches in Australia between 2009 and 2016 were analysed using a signal detection paradigm. Umpire sensitivity (A) and response bias (B) were compared to chance performance in three formats of the game: Four-day, One-day, and T20. Mixed effects models assessed sensitivity and response bias differences between match types.ResultsUmpires were able to differentiate between “out” and “not out” appeals to a high standard but were conservative and had a bias to respond “not out” in all formats of the game. Umpires were less accurate in the shorter formats of the game, particularly T20 cricket and were also significantly more conservative in T20 compared to Four-day Matches.ConclusionsCricket umpires are conservative and are highly accurate LBW decision makers. However, differences in their judgments were associated with different match formats. The unique task goals and contextual pressures afforded by the shorter formats of the game, particularly T20, may account for the observed performance differences we see here.  相似文献
