The introduction of the Video Assistant Referee supports the fairness of the game – An analysis of the home advantage in the German Bundesliga

The introduction of the video assistant referee (VAR) was a landmark in soccer history, yet it is not empirically examined whether the technology contributes to the most supreme value of the game: fair play. Because referees are said to be one driving cause of the home advantage (HA), the aim of this study was to examine whether the HA changed in the German Bundesliga since the implementation of the VAR in the season 2017/18. We examined a total of 2448 games during the four seasons before and after the implementation of the VAR with regards to the game outcomes (i.e., goals and points) as well as indicators of referee bias (i.e., fouls, yellow cards, 2nd yellow cards, red cards, and penalty kicks) for both the home and the away teams. Findings indicate that the VAR influences game outcomes to a fairer degree. Specifically, (i) we found statistical evidence for the HA before, but not after the implementation of the VAR. However, (ii) these results need to be interpreted with caution because direct assessments of the change induced by the introduction of the VAR are not statistically significant. Finally, (iii) with the implementation of the VAR, fewer fouls were committed by both the home and the away team.     

The impact of differing audience sizes on referees and team performance from a North American perspective

The COVID-19 pandemic provides a natural experimental framework to comprehensively test the effect of crowds on both referees and players. We examine this from a North American perspective, using data from three major leagues: the National Basketball Association (NBA), National Football League (NFL) and National Hockey League (NHL). In all three leagues in the 2020–2021 season, matches were played either in empty stadiums or before diverse audience sizes. We find that the lockdown affects NBA and NFL results, by lowering the prospects of winning and the expected scoring points of the home team, when games are played without an audience. Conversely, the lockdown does not substantially influence the outcomes of NHL games. We also examine the effect of audience size on game outcomes using historical observations from the past decade, when no lockdown measures were in force. Interestingly, a larger audience size increases the chance of winning and the expected scoring points of the visiting team for NFL games. No significant effect of the audience size on match outcomes is observed for NBA or NHL games. Regarding referee decisions, spectators do not significantly influence referee calls of NHL matches. As for NBA and NFL, the lockdown significantly increases the total number of referee calls but does not prompt more biased decisions towards either of the teams. Finally, a larger audience leads to referee calls more favourable to the visiting team for NFL games. These results extend the literature regarding crowd pressure on the behaviour of players and officials, with an indication that the specific sports activity has a pivotal role in the response to a cheering audience.     

Game location and officiating bias in English Club Cricket.

One potential contributing factor to the commonly observed home advantage in competitive sport is that officials may be biased in favour of the home team as a result of pressure from spectators. The present study examined officiating behaviour and home advantage, defined as home teams winning over 50% of decided games in English Club Cricket, a sport virtually devoid of spectator influence. Records of game outcomes, as well as dismissals requiring a decision by the umpire, were analysed. The relative frequency of umpiring decisions did not favour either home or away teams. However, a home advantage was found, with the home teams winning 57.1% of decided games (n = 1.449). Considered together, the results suggest that in sports with little or no spectator influence teams may win more often at home for reasons other than biased umpiring decisions, such as familiarity with their home ground or a visiting team's fatigue following travel.     

High and mighty: Height increases authority in professional refereeing

Throughout the animal kingdom, larger males are more likely to attain social dominance. Several lines of evidence suggest that this relationship extends to humans, as height is positively related to dominance, status and authority. We hypothesized that height is also a determinant of authority in professional refereeing. According to the International Football Association Board, FIFA, football ("soccer") referees have full authority to enforce the laws of the game and should use their body language to show authority and to help control the match. We show that height is indeed positively related to authority status: referees were taller than their assistants (who merely have an advisory role) in both a national (French League) and an international (World Cup 2010) tournament. Furthermore, using data from the German League, we found that height was positively associated with authoritative behavior. Taller referees were better able to maintain control of the game by giving fewer fouls, thereby increasing the "flow of the game". Referee height was also positively associated with perceived referee competence, as taller referees were assigned to matches in which the visiting team had a higher ranking. Thus, height appears to be positively related to authority in professional refereeing.     

Virtual reality as a representative training environment for football referees

Visual experience plays an important role in facilitating referee decision-making. Video training can be used to train these perceptual-cognitive skills in discrete scenarios, for instance in foul situations in football, but is less suitable in other instances such as when seeking to make decisions in open-play scenarios due to a lack of representativeness. Recent technological advances enable the use of virtual reality (VR) to replicate game situations in a controlled and realistic manner. It is however not yet known how representative behaviour in VR would be of behaviour on-field in the natural environment. The aim of the study was therefore to examine the degree to which visual behaviour of football referees in virtual reality would reflect behaviour found when adjudicating matches on-field. Sub-elite football referees completed decision-making tasks in three experimental conditions: on-field (in a real match), in virtual reality and when observing video footage. Across the three environments we compared decision-making performance, visual behaviour (including search rate, fixation duration, and head movements) and the user experience of the referees. Results revealed that behaviour in the VR environment was indistinguishable from that on-field. In contrast, visual-motor behaviour when observing video footage was markedly different to that found on-field (and in VR). The results show that visual-motor behaviour in VR is representative of that found on-field and therefore suggests that VR offers promise as a representative training environment for sports officials to improve on-field performance in the natural environment.     

Assessing whether black uniforms affect the decisions of Turkish soccer referees: is finding of Frank and Gilovich's study valid for Turkish culture?

Frank and Gilovich (1988) found that teams with black uniforms were penalized by referees more than other teams that did not wear black uniforms in the U.S. National Football League (NFL), and the U.S. National Hockey League (NHL). This finding was examined for the referees in the Turkish Premier Soccer League (TPSL) for the soccer teams wearing or not wearing black uniforms during actual games. 30 male referees' (ages 22-45 years, M = 34.8) decisions were analyzed in a total of 2142 Turkish premier soccer league games played in 7 seasons. Using the number of red and yellow cards and penalty kicks teams drew as a penalty decision criteria, no significant differences were found between Turkish soccer teams wearing black uniforms or those not and the number of penalty kicks. This result, which was different from that of Frank and Gilovich's work, was discussed in relation to the social psychological point of view of different cultures and societies.     

Perceptual Judgments of Sports Officials are Influenced by their Motor and Visual Experience

We examined the relation between previous motor and visual experience and current officiating experience of expert judges and referees and their judgments from an embodied cognition viewpoint. A total of 370 sports officials from soccer, handball, ice hockey, and trampoline took part in the study. Analyses revealed that cognitive judgments are related to motor, visual, and officiating experience to different degrees in the analyzed sports. Our findings indicate that, depending on the sport, sports officials should either specialize early in officiating, or gather visuo-motor experience as an athlete or spectator first, and then switch roles to become a sports official.     

A new Bayesian procedure for the estimation of the referees' decision thresholds and agreement. The case of professional handball refereeing

In double refereeing, agreement between referees is fundamental for the achievement of a flawless and smooth refereeing activity. Nonetheless, the agreeement can be affected by several external and internal factors, with a negative impact on the consistency of the refereeing and the fluidity of the game. The referee’s Decision Threshold (DT) is the limit above which the evidence of a foul results in the call of an infraction by the referee. It represents the individual refereeing style, and it is one of the factors that can contribute to low agreement between the referees. We present an application of a new Bayesian procedure to estimate referee’s DT in a typical refereeing task. To this end, 56 italian professional handball (FIGH) referees were asked to evaluate 96 potential foul plays, belonging to four different infraction types: 7-m throw, passive play, offensive foul, disciplinary sanctions. The proposed method provides information about: (i) referee’s individual DT; (ii) the agreement between pairs of referees (i.e., one-to-one); (iii) the agreement between each referee and all the other referees (i.e., one-to-total); (iv) the agreement between each referee and a reference referee (i.e., one-to-expert); (v) the proportion of agreement between the referees and a reference referee for each potential foul play. Sport federations would profit by this procedure in different ways: by using the information about the DT to train referees, by detecting referees with a low agreement with their colleagues or with the reference referee, by focusing training on specific plays to improve the arbitration class internal consistency.     

Rejecting Technology: A Normative Defense of Fallible Officiating

There is a growing consensus in both academic and popular reflections on sport that if the accuracy of officiating can be improved by technology, then such assistance ought to be introduced. Indeed, apart from certain practical concerns about technologizing officiating there are few normative objections, and those that are voiced are often poorly articulated and quickly dismissed by critics. In this paper, we take up one of these objections – what is referred to as the loss of the human element in sport – and try to provide a firmer foundation for the disquiet that some feel at the threat of its loss. Briefly, it is argued that the cost of trying to eliminate all error in officiating through technological means is an understanding of sport as a practice through which human beings can reconcile themselves with the fallibilities and contingencies of life, in a forum where such losses can safely be experienced. After considering both practical and normative counter-arguments against the implementation of technology to correct officiating errors, we offer an argument that fallible officiating should be seen as desirable and that an attitude in sport that seeks to eliminate all wrong decision-making in officiating should be discouraged.     

Connecting Personal History and Organizational Context: Suggestions for Developing Educational Programs for Youth Soccer Coaches

Literature underscores the complex role of coaches in sport organizations, especially in youth sectors. Their need for support, not only on the technical level, is emerging. In recent years an interesting international debate has evolved regarding what education is most suitable to support coach development. The article intends to enter this debate by proposing an educational model for youth soccer coaches. This educational proposal is the outcome of reflection that originated from various experiences with about 110 Italian youth soccer coaches over the past six years. The first part is dedicated to a review of the literature on coaching education, and the second to the educational model presented (e.g., theoretical background, characteristics, setting, outcomes, and considerations regarding the management of this educational process). The strength of this model was precisely to have put some recurrent issues in dialogue with the specific organizational contexts in which the educational programs were implemented.     

Are there any Good Arguments Against Goal-Line Technology?

Despite frequent calls by players, managers and fans, FIFA's resistance to the implementation of goal-line technology (GLT) has been well documented in national print and online media as well as FIFA's own website. In 2010, FIFA president Sepp Blatter outlined eight reasons why GLT should not be used in football. The reasons given by FIFA can be broadly separated into three categories; those dealing with the nature and value of the game of football, those related to issues of justice, and those concerned with the practical implementation of GLT. This paper intends to evaluate these eight reasons in order to assess whether there are, indeed, any good arguments against GLT in football.     

Players’ Gender and Male Referees’ Decisions About Aggression in French Soccer: A Preliminary Study

The aim of this study was to examine (a) aggression displayed by players and (b) referees decisions about these behaviors as a function of the gender of the players in French soccer. Twenty-six games (13 for women and 13 for men) were videotaped. Instrumental aggressive acts and referees decisions were then observed. The findings indicated a significant effect of gender on instrumental aggression and referees decisions related to these behaviors. Male players displayed more instrumental aggressive acts than female players did. Nevertheless, relative to the total number of aggressive acts displayed, referees penalized women more than men. Gender stereotypes might be a relevant explanation for these results, as soccer is generally perceived as a masculine-type sport, particularly in France, and aggression as a masculine characteristic.     

Soccer referees’ experience of threat and aggression: Effects of age,experience, and life orientation on outcome of coping strategy

The present study examined the circumstances pertaining to threat and aggression during soccer matches as experienced by 107 provincial Soccer Association referees. Three sources of aggression were identified—soccer players, coaches/trainers, and spectators—and the main measures included threat and physical and verbal aggression. Several outcomes, including prematch worry and effects on concentration, performance, and motivation, were affected by the incidence of threat and aggression, and these outcomes were found to be affected by the age, degree of experience, and life orientation of the referees. Younger referees were shown to be the most prone to threat and aggression. Referees with a generally pessimistic orientation experienced less motivation, worse performance, and greater problems coping with aggressive behavior from the spectators compared with referees with a generally optimistic orientation.

A game-to-game investigation of the relation between need-supportive and need-thwarting coaching and moral behavior in soccer

ObjectiveAlthough perceived need-supportive and need-thwarting coaching have received considerable attention, the question whether coach behavior fluctuates from game to game, with resulting associations with players’ moral behavior has not been examined.Design and methodA Belgian sample of soccer players (N = 197; M = 26.57) was followed during five competition games, with players completing measures both prior to and following each game assessing, pre-game and on-game perceived coaching as well as athletes’ moral behavior.ResultsResults of multilevel analyses indicated that there exists substantial variation in perceived need-thwarting and need-supportive coaching behavior from game to game. The game-to-game variation in perceived pre-game need-thwarting coaching behavior related positively to variation in the adoption of an objectifying stance, which, in turn, related to variation in antisocial behavior oriented towards the opponent, the referee, and even their own teammates. Variation in perceived on-game need-supportive and need-thwarting coaching behavior yielded an additional relation to team-related moral outcomes. Finally, supplementary analysis indicated that these effects also held for an objective marker of moral functioning (i.e., number of yellow cards) and that players’ level of competition-contingent pay related to their antisocial behavior via an objectifying stance.ConclusionThe discussion highlights the fluctuating and dynamic nature of motivating coaching behavior, and its association with players’ moral functioning.     

Exploring children’s movement characteristics during virtual reality video game play

There is increasing interest in the use of commercially-available virtual reality video gaming systems within pediatric rehabilitation, yet little is known about the movement characteristics of game play. This study describes quantity and quality of movement during Nintendo Wii and Wii Fit game play, explores differences in these movement characteristics between games and between novice and experienced players, and investigates whether motivation to succeed at the game impacts movement characteristics. Thirty-eight children (aged 7–12) with and without previous game experience played Wii (boxing and tennis) and Wii Fit (ski slalom and soccer heading) games. Force plate data provided center of pressure displacement (quantity) and processed pelvis motion indicated smoothness of pelvic movement (quality). Children rated their motivation to succeed at each game. Movement quantity and quality differed between games (p < .001). Children with previous experience playing Wii Fit games demonstrated greater movement quantity during Wii Fit game play (p < .001); quality of movement did not differ between groups. Motivation to succeed did not influence the relationship between experience and outcomes. Findings enhance clinical understanding of this technology and inform the development of research questions to explore its potential to improve movement skills in children with motor impairments.     

Social information processing in strategic decision-making: Why timing matters

In strategic decision situations, as modeled in games, the outcome depends on all decision-makers involved. In such situations, people make different decisions when they move simultaneously as compared to when they move sequentially without knowledge of prior moves. This is called the timing effect, which is not predicted by classic game theory. We hypothesize that pseudo-sequential game structures activate concepts of social interactions, which in turn increase individual’s interpersonal trust and decreases cautiousness in situations of interdependence. Simultaneous game structures are more likely to activate concepts of games of chances, as a consequence of which the possibility of an actual total loss is more salient. In four experiments, participants played a coordination game either simultaneously or pseudo-sequentially. We manipulated processing time (Experiment 1), assessed participants’ perception of game features (Experiment 2), manipulated activation of concepts such as social interaction (Experiment 3), and asked participants what decision they make being in a social interaction or a game of a chance (Experiment 4). The results support our hypothesis that different cognitive processes, which either intensify or diminish the focus on the other person, mediate the timing effect. In Experiment 5 we reversed the timing effect by embedding the game in a competitive context.     

National security games

Issues that arise in using game theory to model national security problems are discussed, including positing nation-states as players, assuming that their decision makers act rationally and possess complete information, and modeling certain conflicts as two-person games. A generic two-person game called the Conflict Game, which captures strategic features of such variable-sum games as Chicken and Prisoners' Dilemma, is then analyzed. Unlike these classical games, however, the Conflict Game is a two-stage game in which each player can threaten to retaliate — and carry out this threat in the second stage — if its opponent chose noncooperation in the first stage.Conditions for the existence of different pure-strategy Nash equilibria, or stable outcomes, are found, and these results are extended to situations in which the players can select mixed strategies (i.e., make probabilistic threats or choices). Although the Conflict Game sheds light on the rational foundations underlying arms races, nuclear deterrence, and other strategic situations, more detailed assumptions are required to tie this generic game to specific conflicts.Steven J.

Establishing Standards for Basketball Elite Referees' Decisions

Basketball referees' decisions in ambiguous situations are supposed to adhere to common standards. We propose that standards can be established by video training-programs. Thirty-three German elite basketball referees participated in an online experiment. Feedback during a learning phase influenced decisions (foul vs. no call) in a subsequent test phase. These results provide a starting point for further investigations into establishing standards for referees. They suggest that establishing standards for referees' decisions in ambiguous situations may be a worthwhile approach for improving the quality of referees' decisions.     

Is behavioral pro-sociality game-specific? Pro-social preference and expectations of pro-sociality

We observed the behaviors of the same people across five games – two prisoner’s dilemma games, a trust game (in which the subject took on the role of both truster and trustee), a dictator game, and a faith game – any pair of which was separated by an interval of several months to reduce potential carry-over effects, and found strong consistency in behaviors among these games. We also found consistency between the expectations of other players’ behaviors and the player’s own behavior across games. We further found that the consistent behavioral pro-sociality observed across different games was related to the general measures of pro-social value orientation and perceiving the game situations. These findings suggest that individual and cultural differences in game behaviors can reflect both the ways in which people perceive game situations and their general social preferences.     

Factors Underpinning Football Officiating Excellence: Perceptions of English Premier League Referees

The purpose of the present study was to identify factors perceived to underpin football officiating excellence. Semi-structured interviews were conducted to collect data from 15 English Premier League referees. Through inductive content analysis, emerging themes were identified and comprised a variety of physical, environmental, and psychological factors: (a) mental toughness attributes, (b) support networks and services, (c) effective game management qualities, (d) multifaceted pre-match preparation, (e) performance-level enhancement, (f) opportunities to thrive, (g) personal characteristics, and (h) superior physical components. Findings acknowledge theoretical and applied implications for sport psychology professionals operating in elite football officiating.
