Influencer les jugements de l'adversaire au cours des interactions sportives compétitives : un exemple en tennis de table

This study analysed the masking activity of table tennis players, and any activity attempting to influence opponent's perceptions. We studied the activity of five French table tennis players during national matches in reference to the course of action theory (Theureau, 1992). Matches were videotaped, and the players' verbalizations as they viewed the tapes were collected a posteriori. The data were analysed by 1) transcribing the players' actions and verbalizations, 2) decomposing their activity into elementary units of meaning, and 3) analysing the meaningful structures of the course of action. The results showed that a large part of the table tennis players activity attempts to influence opponent's judgments. This activity aims to 1) modify the opponent's emotional experience, and 2) influence the opponent's perception of adversarial relationship. It is expressed through strokes and behaviors not related to the game. Our results lead to a new perspective of table tennis matches analysis in term of collective activity and “shared context” (Salembier and Zouinar, 2004).     

How many creatives are enough? Exploring how manipulating the number of creative players in the opposing team impacts footballers' performance during small-sided games

This study explored how varying the number of creative opponents affects youth players' performance during football small-sided games (SSGs). Initially, 60 players from 3 different age groups with n = 20 in each (under-9, U9; under-11, U11; and under-13, U13) were tested during SSGs to rank them according to their creative potential. Based on these rankings, four players shown to possess with a medium creative potential were assigned to the intermediate team for each age group. This team competed against a team on which players with high creative potential were progressively included (from one to finally all four players, 1C to 4C) during a 4-a-side plus goalkeeper SSG. The results showed that U9 players increased the individual space explored when facing more creative opponents (p = .012), while the U11 (p = .026) and U13 (p < .001) only increased when facing 2C and 3C. Playing against more creative opponents induced more variability in the distance to own (p = .046) and the opponent team's centroid (p = .046) in the U9, regularity in the U11 (team centroid, p < .001; opponents' centroid, p = .001) and lower regularity in the U13 (team centroid, p = .013 opponents' centroid, p = .009). These distinct movement patterns seemed to reflect the differences in players' perceptual and motor skills. A higher creative score was found against 1C (vs 2C and 4C, p = .006) and 3C (vs 4C, p = .006) in the U9. The results from the effect sizes indicated higher values on the players' attempts, fluency and versatility when facing 1C to 3C, whereas a clear decrease was observed against 4C for all age groups. Hence, moderate and high demanding scenarios prompt the emergence of new behaviours while extremely high demanding scenarios (i.e. 4C) seem to constrain all the creativity components. Overall, adding creative players mostly impacts the team's collective behaviour rather than the players' creativity-related skills.     

The intricacies of verbalizations,gestures, and game outcome using sequential analysis

ObjectivesThe purpose of the present study was to identify the intricacies of verbalizations, gestures, and game outcome during competition.DesignThe behavioral research software Observer XT^® using sequential analysis was used to analyze our data.MethodParticipants were 34 junior tennis players with a mean age of 13.68 (SD = 1.8). Youth players were observed during 17 matches using the Self-Talk and Gestures Rating Scale and were examined by a built-in application (Observer XT^®) of mapping of verbalizations, gestures, and performance.ResultsSequences indicated negative verbalizations were the most frequently exhibited form of overt verbalizations, followed by positive and instructional verbalizations. Furthermore negative verbalizations for either the server or the receiver decreased the probability of winning a game and showed verbalizations from the server related to the receiver's verbalizations and game outcome, and vice versa.ConclusionsThe results shed light on how verbalizations and gestures interact differently according to the context, which may have important implications for research that has focused on verbalizations and has neglected gestures and contextualized performance in sport.     

Key players in sport teams. An exploratory study on the effects of attachment styles on intra-team relational networks

Relationship issues in sport are considered vital for the overall wellbeing of athletes (Jowett, 2005). The way athletes interact, create and maintain relationships is thought to be powerfully influenced by the athletes' attachment states of mind (Thomson & Jaque, 2018). To our knowledge, no study so far has investigated the impact players' attachment styles, as personality dispositions, have on overall intra-team relationship dynamics. This paper examines intra-team social relational networks from the perspective of adult attachment theory. Cross-sectional data were collected from 10 sport teams (158 players) from different sports. Self-report data were collected to assess attachment style and social relationships with teammates. Social network analyses (SNA) were used to calculate players' centrality scores based on incoming and outgoing relational nominations. Multilevel linear analysis was further performed to check inferential relationships between the study variables. Data showed that attachment styles of players, as personality dispositions, affected partly centrality degree positions within the various team social relational networks. The study offers an innovative perspective on the interactional and dynamic world of social relationships in sports teams and confirms that attachment style differences among players predispose them to particular positions within the team social relational networks. Although the current research has an exploratory character, it shows a new direction in the study of groups and sport team dynamics.     

From reasonable preferences,via argumentation,to logic

This article demonstrates that typical restrictions which are imposed in dialogical logic in order to recover first-order logical consequence from a fragment of natural language argumentation are also forthcoming from preference profiles of boundedly rational players, provided that these players instantiate a specific player type and compute partial strategies. We present two structural rules, which are formulated similarly to closure rules for tableaux proofs that restrict players' strategies to a mapping between games in extensive forms (i.e., game trees) and proof trees. Both rules are motivated from players' preferences and limitations; they can therefore be viewed as being player-self-imposable. First-order logical consequence is thus shown to result from playing a specific type of argumentation game. The alignment of such games with the normative model of the Pragma-dialectical theory of argumentation is positively evaluated. But explicit rules to guarantee that the argumentation game instantiates first-order logical consequence have now become gratuitous, since their normative content arises directly from players' preferences and limitations. A similar naturalization for non-classical logics is discussed.     

Application of Achievement Goal Theory in an Urban Youth Tennis Setting

The purpose of this study was to examine the motivational responses of tennis players in relation to their goal orientations and perceptions of the motivational climate. Youngsters completed a survey with tennis-specific measures of goal orientations, motivational climate, attitudes toward tennis, their instructor, their fellow players and sportspersonship behaviors. Results support Nicholls' goal perspective theory. Moderated regression analysis suggested that positive perceptions of a task-involving climate and negative perceptions of an ego-involving motivational climate predicted players' attitudes toward sportpersonship, their instructor, and fellow players. Attitudes toward tennis were predicted by task orientation. Canonical analyses further suggested that perceptions of the climate were most strongly related to attitudes.     

Negative mood regulation expectancies and sports performance: an investigation involving professional cricketers

Objectives: To test whether the performance of professional sports competitors is related to their expectancy of improving an unpleasant mood.Method: Two related studies of professional cricketers were conducted. In Study One, 46 players completed a battery of questionnaire scales, including a measure of negative mood regulation (NMR) expectancy. In Study Two, 19 participants from Study One took part in a time-sampling study in which they rated their mood on a pocket computer throughout a competitive match.Results: The results from Study One showed that NMR was significantly correlated with players' batting average for the season. In contrast, reflexivity, well-being, and age were significantly associated with NMR but not with batting average. The results from Study Two showed that players who had greater NMR had significantly higher ratings for happy mood, smaller negative changes in happy mood, and greater batting averages during the match.Conclusions: Results of regression analysis supported an explanation of the association between NMR and performance in terms of a mediating effect of happy mood. Overall, the findings suggest that NMR expectancy can facilitate professional sports performance.     

CORRECTION DES VERBALISATIONS IRRATIONNELLES CHEZ DES JOUEURS DE POKER-VIDEO*

Earlier studies have shown that irrational thinking dominates rational thinking during gambling. The present study evaluated the effects of cognitive restructuring on gambling behaviors among video poker players. Within a single case experimental design across subjects, the results showed that irrational verbalizations decreased during treatment while rational verbalizations increased. Three out of four players reduced their frequency of gambling following treatment. The theoretical and clinical implications of these results are discussed.     

Reconciling the maintenance of on-field success with off-field player development: A case study of a club culture within the Australian Football League

ObjectivesAs a contribution to developing understanding of how professional athletes may successfully develop a dual career and maintain a balance between life on and off the field, the present study sought to analyse a professional Australian Football club culture that has been identified within the industry as successfully supporting player dual career development. At the same time the club has been able to maintain a successful on-field record.MethodsA case study methodology was used for the analysis with Schein's (2010) levels of organisational culture providing a theoretical framework. Data were collected by means of fifteen interviews which included players (11), and non-playing staff (4) comprising an executive staff member, a coach, a team manager, and the player development manager. Observations were also made and recorded by the first author during a two week immersion in the club environment.ResultsFour basic assumptions that explained the coherence between espoused values and artefacts concerning dual career development were identified. They were that: dual career development is important however football comes first; balancing sport and off-field life ensures players' well-being and facilitates on-field performance; players should be encouraged to find personal meaning in their dual career activity, and; the club has an ethical responsibility to support player dual career development.ConclusionAnalysis of the findings suggests that the successful support of dual careers requires a coherent club culture, where related activities exist as part of a holistic approach to player development. This approach must recognise the priority placed on athletic performance.     

Psychological talent predictors in early adolescence and their empirical relationship with current and future performance in soccer

ObjectivesThis study examined the relationship of talented soccer players' psychological characteristics with current and future performance.DesignBoth a cross-sectional and a prospective design were used.MethodThe sample consisted of 2677 U12 players in the German talent development program. Self-report questionnaires captured psychological dispositions and skills that were assigned to the areas of motivation, volition, self-referential cognition, and emotion. Current performance was operationalized by a motor score representing speed abilities and technical skills as well as by coaches' subjective ratings (A = highly promotion-worthy, B = promotion-worthy, C = partly promotion-worthy). The level of future performance was assessed by examining whether individuals were selected for professional clubs' youth academies in U16.ResultsThis study revealed that only self-referential cognitions had a significant and relevant association with the motor score (0.10 ≤ r ≤ 0.37). The players in the subjectively rated categories significantly differed in 10 of 17 psychological scales (0.01 ≤ η² ≤ 0.03). In most of the scales, A-players showed more positively connoted values compared to B- and C-players. Logistic regressions demonstrated that 10 of 17 characteristics explained a significant proportion of players' future success. Players with high dispositions in these characteristics had a greater chance of achieving a higher performance level compared to players with low dispositions (1.61 ≤ OR ≤ 2.65).ConclusionsExpanding on previous research, this study enabled comparisons between a wide range of psychological characteristics with regard to their relevance for soccer performance, leading to conclusions for talent identification and development.     

Perceived inclusion in youth soccer teams: The role of societal status and perceived motivational goal climate

ObjectivesOur aim was to investigate the link between youth soccer players' perceptions of the coach-initiated motivational goal climate within their team and their perceptions of inclusion as a function of societal status. Societal status refers to one's national background which numerically forms the majority or a minority in a particular society.Design and methodsSurvey data was collected among 245 male youth soccer players (M = 12.9 years, SD = 1.60), who all played in culturally diverse teams in the Netherlands. The societal status of 94 players (38.4%) was majority, and 151 players (61.6%) were classified as minority. To test our main hypothesis, perceived inclusion as the dependent variable was hierarchically regressed on coach-initiated mastery goal climate perceptions, performance goal climate perceptions, societal status, and their interactions.ResultsOverall, mastery goal perceptions and performance goal perceptions of intra-team competition were positively and negatively related, respectively, to perceived team inclusion. As hypothesized, only among players with a societal minority status, perceptions of inclusion were higher when mastery goal climate perceptions were higher and performance goal climate perceptions were lower.Discussion and conclusionOur findings suggest that a coach-initiated mastery-oriented team climate may enhance an inclusive soccer environment in culturally and nationally diverse teams. For societal minority players, intra-team competition should be de-emphasized by the coach in order to strengthen the experience of inclusion.     

Doing it for the team: Soccer coaches' identity leadership predicts players' effort,turnover intentions,and performance

ObjectivesThe present research investigates how coaches' identity leadership predicts individual and team outcomes in soccer. Specifically, we tested hypotheses that coaches' identity leadership would be associated with players' perceptions of (a) higher team effort, (b) lower turnover intentions, (c) better individual performance, and (d) better team performance. In addition, we aimed to examine the relationship between coaches' identity leadership and increased team identification of players and the degree to which the associations of identity leadership with these various outcomes were mediated by players' strength of team identification.DesignWe conducted a cross-sectional study of male soccer players in Germany.MethodThe final sample consisted of 247 male soccer players nested in 24 teams that completed measures of their coaches' identity leadership, team identification, team effort, turnover intentions, and individual/team performance.ResultsAnalysis revealed a positive relationship between coaches' identity leadership and team effort, as well as individual and team performance. Moreover, coaches' identity leadership was associated with lower turnover intentions. There was also evidence that the relationships between identity leadership and the investigated outcomes were mediated by team identification.ConclusionsThese findings support claims that coaches' identity leadership is associated with better individual and team outcomes because it helps to build a sense of ‘we’ and ‘us’ in the team they lead.     

Professional handball coaches management of players' situated understanding during official games

ObjectivesThis study, based on the team cognition approach, investigated the information content expressed by coaches when helping players build or update their understanding of the unfolding game. The focus was on how this content fits into the usual task-work/teamwork and procedural/declarative taxonomies.DesignThe data were collected through the audio and video recording of the communications and behaviors of three professional head coaches throughout a total of 15 games. We used deductive content analysis, crossing information contents related to task-work or teamwork with information contents related to declarative or procedural knowledge across the five game periods (first and second half of the first and second half-time, break-time period), and the three score differentials between the teams (favorable, balanced, and unfavorable).MethodWe first performed a multivariate analysis of variance (MANOVA) using a 5 (Game Periods) × 3 (Score Difference) factorial design. Follow-up ANOVAs with repeated-measures were performed to identify the variables contributing to the multivariate effect. We then performed a repeated-measures analysis of variance for information contents related to declarative and procedural knowledge in occurrences of task-work and teamwork categories.ResultsThe results showed that the coaches expressed information related more often to players' procedural knowledge than to their declarative knowledge. We discovered two main effects (game periods and score differences) in coaches' information contents delivered to players. Information related to procedural knowledge was not addressed to the team as a whole, but to certain players.ConclusionsThis suggests that an information flow was more distributed than shared.     

Perception of Affordances for Striking Regulates Interpersonal Distance Maneuvers of Intermediate and Expert Players in Kendo Matches

In daily life and in many sports, people must adjust interpersonal distance between themselves and others based on task constraints and goals. For example, in martial arts such as boxing and kendo, players must adjust interpersonal distance before starting or defending strikes. However, it is not clear what players perceive and how players use this perceptual information to maneuver interpersonal distance and start strikes during real matches. We investigated players' perception of affordances and the criteria for perception and behaviors, and how these change with expertise, using real kendo matches as a one-on-one opponent task. Players perceived affordances for striking for themselves and for their opponent based on subtle interpersonal distance changes and clearly switched stepping forward and backward. In addition, players perceived affordances for strike success and entered closer interpersonal distance than the possible striking distance to increase their own striking ability and exited the closer distance to decrease their opponent's striking ability, respectively. Furthermore, expert players stayed in and moved into the critical interpersonal distance more frequently than intermediate players did. Our research indicates a relationship between action-scaled affordance perception of and maneuvers associated with interpersonal distance in one-on-one situations that occur in daily life and in many sports.     

Performance-induced emotions experienced during high-stakes table tennis matches

ObjectivesTo characterize the contents of emotions experienced by elite table tennis players during high-stakes matches and the situational elements that contribute to these experiences.DesignA four-case study.MethodThree top-level table tennis players from the French Men's Table Tennis Team volunteered to participate in the study. Four matches were studied. Procedures involved: (a) videotaping high-stakes table tennis matches, (b) conducting self-confrontation interviews with players after matches, (c) transcribing the players’ actions and self-confrontation data, (d) decomposing their activity into elementary units, and (e) identifying typical contents of emotion and typical emotional situations.ResultsThe contents of players’ emotions varied during matches. The pleasant or unpleasant tone of emotional content was linked to the set result and the interpretations of the unfolding situation. However, other elements of the competitive interaction (score configurations, judgments about the strokes performed) had a strong emotional coloration. Certain similar events (e.g., bad sensations during stroke performance) were frequently coupled with similar emotional content (e.g., displeasure).ConclusionsUntil quite recently, the predominant focus in sport psychology has been on pre-performance emotions, with far less attention paid to the subjective emotional experiences that occur during task execution. This exploratory study provides initial empirical support for the notion of bi-directionality in emotion–performance relationships [Hanin, Y.L. (Ed.). (2000). Emotions in sport. Champaign, IL: Human Kinetics; Hanin, Y.L. (2003). Performance related emotional states in sport: A qualitative analysis.

Deliberate practice predicts performance over time in adolescent chess players and drop‐outs: A linear mixed models analysis

In this study, the longitudinal relation between deliberate practice and performance in chess was examined using a linear mixed models analysis. The practice activities and performance ratings of young elite chess players, who were either in, or had dropped out of the Dutch national chess training, were analysed since they had started playing chess seriously. The results revealed that deliberate practice (i.e. serious chess study alone and serious chess play) strongly contributed to chess performance. The influence of deliberate practice was not only observable in current performance, but also over chess players' careers. Moreover, although the drop‐outs' chess ratings developed more slowly over time, both the persistent and drop‐out chess players benefited to the same extent from investments in deliberate practice. Finally, the effect of gender on chess performance proved to be much smaller than the effect of deliberate practice. This study provides longitudinal support for the monotonic benefits assumption of deliberate practice, by showing that over chess players' careers, deliberate practice has a significant effect on performance, and to the same extent for chess players of different ultimate performance levels. The results of this study are not in line with critique raised against the deliberate practice theory that the factors deliberate practice and talent could be confounded.     

Identification With Video Game Characters as Automatic Shift of Self-Perceptions

Two experiments tested the prediction that video game players identify with the character or role they are assigned, which leads to automatic shifts in implicit self-perceptions. Video game identification, thus, is considered as a kind of altered self-experience. In Study 1 (N = 61), participants either played a first-person shooter game or a racing game. Subsequently, they performed an Implicit Association Test (IAT) designed to detect cognitive associations between character-related concepts and players' self. Findings indicate a stronger automatic association of military-related concepts to shooter players' self and a stronger association of racing-related concepts to racing game players' self. Study 2 (N = 48) replicated the IAT result from Study 1 and demonstrated the stability of the identification pattern. Implications for identification as an element of the video game experience and future research directions are discussed.     

Intergroup competition for the provision of step-level public goods: Effects of preplay communication

Thirty-two groups of three subjects each participated once in an intergroup public goods game (IPG) in which two groups compete for the provision of step-level public goods. Half of the groups were allowed to discuss the conflict before their members decided privately and anonymously whether to contribute their endowments to their group benefit, and half were not given this opportunity. The results show that preplay group discussion enhances the percentage of contributors and changes the players' estimates about the decisions of the other players. The theoretical implications of the results are examined within the framework of a new model which relates the individual decision to contribute or not to the reward structure, altruism, and the individual's belief structure.     

Book reading styles in dual‐parent and single‐mother families

Background. Whereas many studies have investigated quantitative aspects of book reading (frequency), few have examined qualitative aspects, especially in very young children and through direct observations of shared reading. Aim. The purpose of this study was to determine possible differences in book‐reading styles between mothers and fathers and between mothers from single‐ and dual‐parent families. It also related types of parental verbalizations during book reading to children's reported language measures. Sample. Dual‐parent (29) and single‐parent (24) families were observed in shared book reading with their toddlers (15‐month‐olds) or young preschoolers (27‐month‐olds). Method. Parent–child dyads were videotaped while book reading. The initiator of each book‐reading episode was coded. Parents' verbalizations were exhaustively coded into 10 categories. Mothers completed the MacArthur Communicative Development Inventory, and the children were given the Bayley scales. Results. All parents differentiated their verbalizations according to the age rather than the gender of the child, but single mothers imitated female children more than males. Few differences in verbalizations were found between mothers and fathers or between mothers from single‐ and dual‐parent families. Fathers allowed younger children to initiate book‐reading episodes more than mothers. For both age groups of children, combined across families, verbalizations that related the book to the child's experience were correlated with reported language measures. Questions and imitations were related to language measures for the older age group. Conclusions. The important types of parental verbalizations during shared book reading for children's language acquisition are relating, questions and imitations.
