Technical variation in a sample of high level judo players

Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.     

How perceived autonomy support and controlling coach behaviors are related to well- and ill-being in elite soccer players: A within-person changes and between-person differences analysis

ObjectivesGrounded in Basic Psychological Needs Theory (Ryan & Deci, 2002), this study examined the temporal relationships between perception of coaches' autonomy support and different facets of controlling behaviors, the satisfaction-frustration of athletes' basic needs, and subjective vitality, self-esteem and burnout in elite sportsmen.MethodsParticipants (N = 110 males) from three elite youth soccer academies in northwest France completed a questionnaire on three occasions during the last three months of the competitive season.ResultsLinear mixed models revealed that perceptions of coach-autonomy support and only two facets of controlling coach behaviors (excessive personal control and negative conditional regard) were related to basic need satisfaction-frustration, which in turn were related to the indices of well- and ill-being. In most cases, the relationships were observed both at the within- and between-person levels, but some were observed only at one level.ConclusionsThe findings highlight the importance of considering the different facets of controlling coach behaviors separately and disaggregating the between-person and within-person effects.     

Red shirt color has no effect on winning in European Soccer: Reanalysis of Attrill et al. (2008) of the English premier league and six additional European leagues

Attrill et al. (2008) conducted a far-reaching study in elite English soccer demonstrating in archival research that from 1946 to 2003 seasons, teams wearing red uniforms were more likely to win championships than teams in other uniform colors, won more at home and had a higher average league position (relative to cross-city rivals). Their study was one of only very few that extended the color-in-context theory (Elliot & maier, 2007) to team, ball-oriented long-duration sports. The current investigation returns to the red superiority hypothesis in professional soccer due to weaknesses in the original evidence for this hypothesis. We conducted two studies testing the red superiority hypothesis in professional soccer. In Study 1a, we first reanalyzed the original data and tested the strength of evidence in favor of the red superiority hypothesis. We then updated the English premier league data (1992–2018) and tested uniform color effects on game outcomes. In Study 2, we attempted to broaden the scope of Study 1 and increase statistical power by testing the red superiority effect during the last 20 years of six major European Soccer leagues (NOS Portugal, German Bundesliga, Dutch Eredivisie, Spanish la Liga, French Ligue 1, and the Italian Serie A). All three tests challenge the validity of the original findings and fail to detect uniform color effects at home play in professional soccer. In light of the current findings and a growing body of research in the field we call into question overall color effects in this athletic context.     

Evaluation of the offensive behavior of elite soccer teams.

The purpose of the present study was to evaluate the offensive behavior of the four elite teams (France, Brazil, Croatia, and Holland) using data from the semifinals of the 18th World Soccer Championship in France in 1998. 28 videotaped soccer games were observed, 7 for each team. The protocol contained the following parameters of evaluation: (a) successful pass in the defensive and middle area, (b) unsuccessful pass in the defensive and middle area, (c) attempt on goal in the offensive area, and (d) cross and follow-up action. A multivariate analysis of variance showed the teams' plan was significantly different only in playing the ball back to the goalkeeper. This last action, used more often by Holland than by the other teams, indicated its restrained offensive behavior, which may be one of the reasons for its defeat in some games.     

Temporal links to performing under pressure in international soccer penalty shootouts

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.     

Team history and choking under pressure in major soccer penalty shootouts

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.     

Linda versus World Cup: Conjunctive Probabilities in Three-event Fictional and Real-life Predictions

Conjunction errors in probability judgments have been explained in terms of representatives, non-normative combination procedures, and linguistic, conversational, or conceptual misunderstandings. In two studies, a three-event variant of the classical Linda scenario (Tversky and Kahneman, 1983) was contrasted with estimates of Norway’s chances in three coming World Cup soccer matches. Conjunction errors occurred even in the latter, real-life prediction task, but much less frequently than in the fictional Linda case. Magnitude of the conjunction effect was found to be dependent upon type of constituent (fictional versus dispositional), unequal versus equal probabilities of constituent events, prediction of positive versus negative outcomes, and, for real-life predictions only, umber of constitutent events. Fictional probability ratings were close to but lower than representativenss ratings, giving evidence for a representativeness and adjustment-for-uncertainty strategy, whereas probabilities of real-life events were given a causal model interpretation.     

Forecasting from ignorance: the use and usefulness of recognition in lay predictions of sports events

Whereas previous studies on how people make forecasts of sports events focused primarily on experts, we examined how laypeople do this task. In particular, we (a) tested the recognition heuristic [Goldstein, D. G., & Gigerenzer, G. (2002). Models of ecological rationality: the recognition heuristic. Psychological Review, 109, 75-90], which requires partial ignorance, against four alternative mechanisms in describing laypeople's forecasts for the European Soccer Championships 2004; (b) evaluated how well recognition predicted the outcomes of the matches compared to direct indicators of team strength (e.g., past performance, rankings); and (c) studied the less-is-more effect--the phenomenon that knowing less leads to more correct forecasts than knowing more--which can occur when the recognition heuristic is used. Two groups of participants (laypeople, experts) made forecasts for the first-round matches of the tournament. Of the five candidate mechanisms, the recognition heuristic predicted laypeople's forecasts best: when applicable, it accounted for 90% of the forecasts. The recognition heuristic correctly predicted the actual winner of the matches substantially better than chance but did not achieve the accuracy of direct indicators of team strength. The experts made more correct forecasts than the laypeople. Moreover, we found no benefit of ignorance among the group of laypeople, although the conditions for a less-is-more effect specified by Goldstein and Gigerenzer were fulfilled.     

A new method for assessing squash tactics using 15 court areas for ball locations

Tactics in squash have typically been assessed using the frequency of different shot types played at different locations on the court either without reference to other relevant information or on the basis of the preceding shot. This paper presents a new squash specific method for categorizing court locations in which the ball was played, a novel techniques for assessing the reliability of this method and presents typical shots responses in these new areas controlled for preceding shot as well as the time between shots and the handedness of the players. Twelve games were viewed using the SAGIT/Squash software and 2907 shots viewed a second time from a video image taken from behind the court with an overall agreement of 88.90% for the court location data and 99.52% for shot type. 3192 shots from 9 matches from the 2003 World Team Championships were analyzed in SAGIT/Squash. In the court areas analyzed between 2 and 7 shot responses were predominant suggesting tactical patterns were evident. This was supported by differences evident between shot responses played from the two back corners where the backhand side was characterized by a predominance of straight drives whereas straight and crosscourt drives were played on the forehand side. These results tended to confirm that tactics i.e., consistent shot types, are played although these are only apparent when factors that determine shot selection are accounted for. This paper has controlled for some of these factors but others need to be considered e.g., if individual player profiles are to be ascertained.     

Influence of ball type on home advantage in French professional soccer

The home advantage has been consistently found in soccer matches, but conclusive evidence of the origin of this home advantage has yet to be identified. One factor often thought to contribute is familiarity with a local facility. The present study examined home advantage in the French professional soccer male championships (20 teams in each Ligue 1 and 2) and explored the influence of soccer ball type on this phenomenon. Whether it is knowing how a soccer ball rolls on a particular grass surface or some other aspect, the home team can react to the situation better if they know from experience what is likely to happen. The results suggest that type of soccer ball may have an influence on home advantage. Confounding factors are discussed.     

Variability and creativity in small-sided conditioned games among elite soccer players

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.     

Perceptual-cognitive expertise, practice history profiles and recall performance in soccer

We examined whether high- or low-performing soccer players, classified based on established measures of perceptual-cognitive expertise, differed in regard to their practice history profiles and ability to recall elements of match performance. In Study 1, we measured perceptual-cognitive expertise in elite (n= 48) and non-elite (n= 12) youth soccer players using empirical tests of perceptual-cognitive skill. We then used a quartile split to stratify elite players into either high-performing (n= 12) or low-performing (n= 12) groups based on their test scores. A group of non-elite soccer players (n= 12) acted as controls. In Study 2, we used an established questionnaire to examine retrospectively the participation history profiles of the three groups. The high-performing group had accumulated more hours in soccer-specific play activity over the last 6 years of engagement in the sport compared to their low-performing counterparts and the non-elite controls. No differences were reported for hours accumulated in soccer-specific practice or competition between the high- and low-performing groups. In Study 3, a novel test was developed to examine episodic memory recall in soccer. Although this test successfully differentiated elite from non-elite players, no differences were evident between high- and low-performing groups, implying that episodic memory recall may not be a crucial component of perceptual-cognitive expertise in soccer.     

Conscientiousness,Its Facets,and the Prediction of Job Performance Ratings: Evidence against the narrow measures

This study empirically tested the predictions of the three basic perspectives on the bandwidth debate about the relationship between personality and job performance, regarding the validity of conscientiousness and its facets. The sample consisted of 226 police officers. Conscientiousness and three facets (order, industriousness, and self‐control) were correlated with three performance criteria (overall job performance, task performance, and orderliness). A Schmid–Leiman transformation made it possible to residualize the variance of the facets and to isolate their unique contribution to the prediction of performance measures. The results showed that conscientiousness predicted the three criteria (true validities of.25,.28 and.37, respectively) and that the facets neither predicted job performance nor showed incremental validity over conscientiousness. Finally, the implications of the findings for theory and practice are commented on, and future research is suggested.     

Stress,Coping, and Emotions on the World Stage: The Experience of Participating in a Major Soccer Tournament Penalty Shootout

This study was designed to capture the first-hand experiences of stressors, coping, and emotions that elite professional soccer players have during a major soccer penalty shootout. Eight players who each took part in an important European Championships penalty shootout were interviewed. The results showed that the experience of stressors, coping, and emotions changed extensively throughout the event. Moreover, the participants experienced a series of different stressors, some of which were specific to the penalty shootout, and they employed a variety of coping strategies. Anxiety was the most common emotion. Practitioners can use these results to help design valid simulation protocols.     

Anxiety sensitivity and the five-factor model of personality.

Relations between anxiety sensitivity (AS) and the higher-order and lower-order dimensions of the 'Big Five' model of personality were examined in 317 university students. AS was significantly associated with a number of personality domains and facets of the NEO-PI-R. Regression analyses indicated that only the higher-order domains of neuroticism and extraversion (negatively) and the lower-order N facets of anxiety and self-consciousness, significantly predicted AS. Three lower-order factors within AS were identified and were also compared to NEO-PI-R domains and facets. In a hierarchical regression, the three AS factors significantly predicted variance in a measure of panic-related anxiety after the effects of the six N facets were statistically controlled. Results are discussed in the context of previous work with a Big Three taxonomy of personality and implications for understanding the nature and possible origins of AS are outlined.     

On some philosophical foundations of the disappointing performances of the African soccer teams in world competitions

For decades, African senior club and national soccer teams, involved in world competitions (FIFA World Cup and FIFA Club World Cup), have failed to perform beyond mere honorable appearances. In this paper, we explore two of the fundamental causes underlying these disappointing performances. First, we examine the dilemma which forces almost all the African federations to overlook the Africa-based players in favor of those based outside the continent. Second, we show that the roots of the poor performances of the African teams go far beyond this crippling dilemma. Indeed, we argue, the persistent underperformances of African teams appear to be rather consistent with the fate of postcolonial Africa itself, a continent marred in an acute identity crisis. In fact, this crisis essentially stems from the relentless brain drain inflicted on the African soccer world which has so far dispersed its best talents all across Europe and beyond through the naturalization of its soccer diaspora. In addition, Africa has shown no ability to offer any type of attractive alternatives to the talented sons and daughters of its diaspora as well as to any other world class players. This ineptitude, coupled with Africa’s inability to leave behind its nostalgic Senghorian soccer essentialism, condemns the continent to perpetual poor performances. Therefore, we suggest that the African national federations and their respective governments move away from their deeply held soccer essentialism in order to begin to move toward some kind of soccer existentialism alongside such European countries as France, Germany, Switzerland, and The Netherlands which appear to acknowledge, perhaps reluctantly, the invaluable contributions made by the African (and other world) diaspora to the success of not only their local and national leagues but also their national teams.     

Facets of dynamic positive affect: differentiating joy, interest, and activation in the positive and negative affect schedule (PANAS)

This article proposes the differentiation of Joy, Interest, and Activation in the Positive Affect (PA) scale of the Positive and Negative Affect Schedule (PANAS; D. Watson, L. A. Clark, & A. Tellegen, 1988). Study 1 analyzed the dynamic course of PA before, during, and after an exam and established the differentiation of the three facets. Study 2 used a multistate-multitrait analysis to confirm this structure. Studies 3-5 used success-failure experiences, speaking tasks, and feedback of exam results to further examine PA facets in affect-arousing settings. All studies provide convincing evidence for the benefit of differentiating three facets of PA in the PANAS: Joy, Interest, and Activation do have distinct and sometimes even opposite courses that make their separation meaningful and rewarding.     

The contribution of external and internal features to the matching of unfamiliar faces

The relative efficacy of external and internal features in matching unfamiliar faces was studied in three experiments in which the subjects matched target and test faces differing in terms of external or internal features, or both. In Experiment 1 only full congruency between target and test faces was considered a match; in Experiments 2 and 3 faces sharing the same external and internal features were also considered to be matches. A total of 100 subjects matched 192 pairs of target and test faces in a same-different task. Reaction times and matching errors were recorded for analyses of variance. In all three experiments performance was best when either all features matched or all features mismatched, with mismatches having a slight edge. When matches of external and internal features with the target faces were inconsistent with each other, mismatches of external features led to faster responses in Experiments 1 and 2, and mismatches of internal features led to faster responses in Experiment 3. The results suggest that since faces are configurational stimuli, face matching is influenced by the non-relevant set of features; and that mismatches, especially of external features, influence face matching more than matches do.     

Empathic,moral and antisocial outcomes associated with distinct components of psychopathy in healthy individuals: a Triarchic model approach

In the present report we analyzed the associations between the facets of the recent Triarchic Measure of Psychopathy (TriPM) and distinct dimensions of empathy, morality, and antisocial behavior.Three hundred and seventy-four participants from the community completed the TriPM, the Interpersonal Reactivity Index and the Moral Foundations Questionnaire. A subset of one hundred and three participants completed a self-reported delinquency scale.In line with the multidimensional nature of the TriPM, we found that different facets of psychopathy were associated with distinct domains of empathy and morality. In addition, every TriPM subscale was positively related to self-reported delinquency, although meanness lost its predictive power when its shared variance with disinhibition was controlled.Our results lend conceptual validity to each of the Triarchic model’s traits and suggest that psychopathy should not be regarded as a unitary construct, but rather as a combination of dimensional traits with distinct etiologies.
