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.     

Self-efficacy,mental models and team adaptation: A first approach on football and futsal refereeing

ObjectiveWithin the football and futsal refereeing context, even though referees work within teams, there is very little research considering the implications of team dynamics. In response, this study starts to address this gap in the literature by investigating the moderating effect of mental models on the relationship between self-efficacy beliefs and perceptions of team adaptation within the exciting context of professional and national football and futsal refereeing.DesignWe obtained online questionnaires from 339 active football and futsal referees within the National and Professional league at two distinct points (April and May) within the football season.ResultsSelf-efficacy beliefs were positively associated with perceptions of team adaptation (only for football referees). Mental models were positively associated with team adaptation. Likewise, the moderation between mental models and self-efficacy beliefs was positively associated with perceptions of team adaptation. However, such an effect was only significant at the futsal referees’ level.ConclusionThis study emphasises the importance of mental models for team adaptation and the importance of self-efficacy beliefs in predicting perceptions of team adaptation. We hope that this study represents the first step in a greater appreciation of the salience of team dynamics and their impact on football and futsal referees’ performance and that future research can build upon our work.     

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.     

The assistant referees’ activity in refereeing elite football: Preoccupations when not judging offside

ObjectiveThe purpose of this research was to study the preoccupations assistant referees had to participate in decision making about duels during football games.DesignResearch adopted a phenomenological framework to investigate the assistant referees’ lived experiences in order to understand their activity when they judged duels in match.MethodThis study investigated six professional football matches. Researchers conducted a participatory observation of the refereeing team before each match. Twelve self-confrontation interviews with each assistant referee of each match were conducted in order to make him/her describing his/her unfolding lived experience during the match.ResultsIn case of players’ duels, the perception of contextual cues enabled the assistants to appraise the occurring of a decision process with the central referee. For the assistants, the occurring of a decision process with the central referee meant his priority to intervene in the adjudication of duels, while the absence of decision process with the central referee meant for the assistants the possibility to intervene. The assistants adjusted their way of judging duels to how the central referee judged the previous ones.ConclusionsThe participation of assistants in decision making about duels depends on their preoccupations concerning the central referee’s priority. The way assistants perceive the central referee’s contextual judgment shapes the way they adjudicate duels. A latent intention to coordinate with the central referee, in relation with their collaborative tasks, is embedded in their preoccupations. Our results are a platform to develop further research about the referees’ collective activity.     

The Fallacies of the Assumptions Behind the Arguments for Goal-Line Technology in Soccer

Lately, a number of referee decisions appear to have reignited the debate over the need to bring more in-game officiating technology into soccer. The fallacies behind the arguments for the inclusion of technology to aid game officials can be narrowed down to those behind current arguments for or against goal-line technology. Both the proponents and opponents of these arguments appear to overemphasise the role of referees to the point of claiming that if refereeing errors could be eliminated in goal-line situations, then the most deserving team would most of the time be expected to win the contest. While we firmly believe that the game of soccer would benefit immensely from infallible officiating, we intend to show that these arguments are founded upon a number of inconspicuous assumptions. First, they assume that goal-line situations can be shown to affect the outcomes of games more than all other game situations. This can easily be shown to be a myth, since goals can be scored from all areas of the playing field. In addition, winning a soccer game, obviously, involves more than just scoring goals. Second, these arguments seem to support the view that referee decisions affect the outcomes of games more than decisions made by players, coaches and managers. This is merely a myth, since one can show that, in light of Cesar Torres's insights, referee involvement in game is limited to regulating situations that demand that the game be restored to its constitutive actualisation. Third, most arguments for goal-line technology tend to support the erroneous view that technology can actually eliminate most ‘crucial’ human mistakes from sport and, thus, ensure fairness of game outcomes. Such a myth can easily be refuted by reference to numerous cases of inconclusive slow-motion video replays in soccer. Therefore, this paper aims at arguing that, instead of reinforcing the scapegoating of referees and overemphasising the importance of isolated referee decisions to the point of attributing victory or defeat to these ‘crucial’ decisions, both sides of the goal-line technology debate need to put forth compelling arguments which go beyond the current misguided search for referee infallibility.     

The influence of crowd noise and experience upon refereeing decisions in football

Objective. The existence of the home advantage in sport is well known. There is growing evidence that crowd noise plays a crucial part in this phenomenon. Consequently, a quantitative study was undertaken to examine influence of crowd noise upon refereeing decisions in association football (soccer). The association between years of experience and any imbalance in refereeing decisions was also addressed.Methods. To investigate whether the presence or absence of crowd noise might influence qualified referees when assessing various tackles/challenges recorded on videotape. Binary logistic regression was used to assess the effect of crowd noise and years of experience on referees' decisions.Results. The presence of crowd noise had a dramatic effect on the decisions made by referees. Those viewing the challenges with background crowd noise were more uncertain in their decision making and awarded significantly fewer fouls (15.5%) against the home team, compared with those watching in silence.Conclusions. The noise of the crowd influenced referees' decisions to favour the home team. It is suggested that referees' decisions are influenced by the salient nature of crowd noise, the potential use of heuristic strategies, and the need to avoid potential crowd displeasure by making a decision in favour of the home team.     

Gaze behaviors and decision making accuracy of higher- and lower-level ice hockey referees

BackgroundGaze behaviors are often studied in athletes, but infrequently for sport officials. There is a need to better understand gaze behavior in refereeing in order to improve training and education related to visual search patterns, which have been argued to be related to decision making (Abernethy & Russell, 1987a).ObjectiveTo examine gaze behaviors, decision accuracy, and decision sensitivity (using signal detection analysis) of ice hockey referees of varying skill levels in a laboratory setting.DesignUsing an experimental design, we conducted multiple t-tests.MethodHigher-level (N = 15) and lower-level ice hockey referees (N = 15) wore a head-mounted eye movement recorder and made penalty/no penalty decisions related to ice hockey video clips on a computer screen. We recorded gaze behaviors, decision accuracy, and decision sensitivity for each participant.ResultsResults of the t-tests indicated no group differences in gaze behaviors; however, higher-level referees made significantly more accurate decisions (both accuracy and sensitivity) than lower-level referees.ConclusionHigher-level ice hockey referees are superior to lower-level referees on decision making, but referees do not differ on gaze behaviors. Possibly, higher-level referees process relevant decision making information more effectively.

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.

Multi-Informant Assessments of Adolescent Social Anxiety: Adding Clarity by Leveraging Reports from Unfamiliar Peer Confederates

Adolescent social anxiety (SA) assessments often include adolescent and parent reports, and low reporting correspondence results in uncertainties in clinical decision-making. Adolescents display SA within non-home contexts such as peer interactions. Yet, current methods for collecting peer reports raise confidentiality concerns, though adolescent SA assessments nonetheless would benefit from context-specific reports relevant to adolescent SA (i.e., interactions with unfamiliar peers). In a sample of 89 adolescents (30 Evaluation-Seeking; 59 Community Control), we collected SA reports from adolescents and their parents, and SA reports from unfamiliar peer confederates who interacted with adolescents during 20-minute mock social interactions. Adolescents and parents completed reports on trait measures of adolescent SA and related concerns (e.g., depressive symptoms), and adolescents completed self-reports of state arousal within mock social interactions. Adolescents’ SA reports correlated with reports on parallel measures from parents in the .30s and with peer confederates in the .40s to .50s, whereas reports from parent-confederate dyads correlated in the .07 to .22 range. Adolescent, parent, and peer confederate SA reports related to reports on trait measures of adolescent SA and depressive symptoms, and distinguished Evaluation-Seeking from Community Control Adolescents. Confederates’ SA reports incrementally predicted adolescents’ self-reported SA over and above parent reports, and vice versa, with combined Rs ranging from .51 to .60. These combined Rs approximate typical correspondence levels between informants who observe adolescents in the same context (e.g., mother-father). Adolescent and peer confederate (but not parent) SA reports predicted adolescents’ state arousal in social interactions. These findings have implications for clarifying patterns of reporting correspondence in clinical assessments of adolescent SA.     

Inter-individual differences in sport refereeing: A review of theory and practice

Most studies on sport officials ignore the variance of the data in terms of individual differences. Here we highlight the need to focus on these differences in refereeing as the main point and goal of the current review. We argue that the study of individual differences is important for referee selection, development and performance evaluation. We present the available research on differences related to referee communication styles, types of interactions, and game management. We regard expertise and experience level as a key contributor to individual differences. Given the gap in research around the in-group variance, we discuss new directions for research and further recommendations for the field. We suggest that the areas in which more research and practice will inform our selection, training, and evaluation processes are communication and personal communication style, while having more flexibility in applying different refereeing styles to facilitate performance in different contexts.

Perceived psychological stress among high school basketball officials

The purpose of this study was to survey certified high school basketball officials during midseason to assess whether the sources and magnitude of perceived psychological stress would be consistent with previous studies of officials in other sports. The sources and magnitude of perceived psychological stress were measured among 324 high school basketball officials (N=324; 312 men, 12 women) using a revised version of the Ontario Soccer Officials Survey. The mean age was 37.6 yr. (SD= 9.4), and the mean years of basketball refereeing experience was 11.7 yr. (SD=8.3). A random sample (N=498) of all basketball officials in a midwestern state (N=1,011) was used, and 324 of the surveys were returned (65%). The overall variance accounted for with the four factors was 84.7%. The magnitude of stress for these factors ranged from below mild to moderate.     

Finding the right case: the role of predictive features in memory for aviation accidents

Three experiments examined the role of story structure in memory for written aviation accident reports by both pilots and nonpilots. Accident reports follow a standard format providing setting, complication, decision and outcome information. Following the ‘predictive features’ model, it was hypothesized that expertise would facilitate recall, and that pilots would recall most effectively with the complication feature. Pilot and nonpilot participants read and recalled 4 (Experiment 1) or 8 (Experiment 2) accident reports. With four cases, pilots recalled more than nonpilots, but no difference was found with eight cases. A primacy effect for pattern of recall was found in Experiment 1 with the setting and complication features most effective in triggering case recall. When task difficulty was increased (Experiment 2), the complication feature alone was the most effective. In Experiment 3, we manipulated text structure and found that complication and decision features were better recognized than setting or outcome features by nonpilots. The finding across three studies that the complication feature was consistently the most effective for retrieving aviation accident reports supports the ‘predictive features’ model.

Decision-making by experienced rugby referees: use of perceptual information and episodic memory

The expertise paradigm was used in two studies to examine decision-making by rugby referees. Videoclips were used to assess infraction detection and knowledge base, or sources of information used. In Study 1, referees of high and low experience were compared, and in Study 2 referees and players were compared. Analysis by signal detection used a framework to classify types of information. Study 1 yielded no differences in detection of infractions as a function of experience, however, referees of high experience used significantly more sources of information than the group with low experience across all categories of information. In Study 2, there were no significant differences between referees and players, with the exception that referees displayed greater use of episodic memory information in decision-making.     

When hockey parents are motivationally imbalanced: Passion,need satisfaction,and verbal aggression toward officials

Spectators can engage in high levels of verbal aggression toward youth hockey officials. Often, the perpetrators of this aggression are the parents. Our aim was to test the motivational factors involved in explaining why hockey parents sometimes take things too far and engage in verbally aggressive behavior toward officials. We reasoned that verbal aggression toward officials would be a function of two forms of motivational imbalance. First, in line with the dualistic model of passion, we hypothesized that verbal aggression would be positively associated with hockey parents’ obsessive passion, an imbalanced form of passion. Also, based on the compensatory model of passion, we predicted that obsessive passion would be associated with imbalanced psychological need satisfaction involving high need satisfaction from being a hockey parent, but low global need satisfaction. We administered online surveys to Canadian hockey parents (N = 992) assessing their verbal aggression toward officials, passion for being a hockey parent, and psychological need satisfaction from being a hockey parent and in general. Using structural equation modeling, we found support for a model in which high need satisfaction from being a hockey parent and low need satisfaction in general were associated with obsessive passion. Obsessive passion, in turn, was associated with greater verbal aggression toward referees. These findings help reveal why some hockey parents insult, threaten, and engage in other forms of verbal aggression toward officials. They also highlight the importance of maintaining motivational balance among sport parents.     

Aging,source memory,and the experience of “remembering”

In a previous study, we found source memory for perceptual features to differentiate between younger but not older adults’ reports of recollective (“remember”; R) and “know” (K) experiences. In two experiments with younger (17–30 years) and older (64–81 years) participants, we examined whether memory for meaningful speaker sources would accompany older adults’ recollective experience. Indeed, memory for male and female speakers (but not partial memory for gender; Experiment 1) as well as bound memory for speakers and their facial expressions (Experiment 2) distinguished between both younger and older adults’ RK reports. Thus, memory for some sources forms a common basis for younger and older adults’ retrieval experience. Nonetheless, older adults still showed lower objective source memory and lower subjective source-attribution confidence than younger adults when reporting recollective experiences, suggesting that source memory is less relevant to their retrieval experience than for younger adults.     

The Discursive Underside of Psychoanalysis: Comments on Cooper’s “Blurring Boundaries”

Surprising for a discipline so dependent on unverifiable reports and theoretical consensus building, psychoanalysis pays little formal attention to its own rhetoric and discourse. In Steven H. Cooper’s thought-provoking challenge to the now highly conventionalized use of the term “boundary” in the mental health field, he raises important questions about the strategies of psychoanalytic theory. While placing Cooper’s proposals in a historical context, this discussion of his paper explores the possibility that closer formal attention to our linguistic habits and the way we play games with words would benefit our capacity for creative clinical thinking.
