Application of the matching law to pitch selection in professional baseball

This study applied the generalized matching equation (GME) to pitch selection in professional baseball. The GME was fitted to the relation between pitch selection and hitter outcomes for five professional baseball pitchers during the 2014 Major League Baseball season. The GME described pitch selection well. Pitch allocation varied across different game contexts such as inning, count, and number of outs in a manner consistent with the GME. Finally, within games, bias decreased for four of the five pitchers and the sensitivity parameter increased for three of the five pitchers. The results extend the generality of the GME to multialternative natural sporting contexts, and demonstrate the influence of context on behavior in natural environments.     

The relationship between visual attention and expertise in sports

ObjectivesGiven the prevalence of misperception and failed perception, particularly in attention-demanding team sports, surprisingly few studies have explored whether experts in team sports differ from other athletes and from non-athletes in their basic attention abilities.MethodIn this study, we examined group differences between experts in team handball (n = 40), athletes from non-team sports (n = 40), and novice athletes (n = 40) using a battery of three attention tasks: a functional field of view task, a multiple-object tracking task, and an inattentional blindness task.ResultsPerformance on the three attention tasks was largely independent, with no significant correlations among the tasks. Team sports experts showed no better performance on the basic attention tasks than did athletes from non-teams sports or novice athletes.ConclusionsThe finding that all basic attention tasks are largely independent provides preliminary support for the idea that attentional breadth, tracking performance, and inattentional blindness are distinct attentional processes. Our results demonstrate that sports expertise effects are unrelated to basic differences in attention—expertise does not appear to produce differences in basic attention and basic differences in attention do not appear to predict eventual expertise. Further experiments could focus on the ways in which more specific attentional strategies and processes contribute to sports performance.     

TEAM SPORTS ACHIEVEMENT AND SELF-ESTEEM DEVELOPMENT AMONG URBAN ADOLESCENT GIRLS

In this study we investigate the contribution of achievement in team sports to adolescent girls' self-esteem development. Adolescent girls ( N = 247) from racially and ethnically diverse backgrounds were surveyed as part of a larger study investigating the development of poor urban youth. Participants responded to items tapping global self-esteem, team sports achievement, and athletic self-evaluations. The results of hierarchical regression analyses indicate that girls' team sports achievement experiences in early adolescence are positively associated with self-esteem in middle adolescence. This relationship is partially mediated by team sports self-evaluations. Applications of these findings to the development of interventions designed to enhance the self-esteem of young women and girls are discussed.     

Further Operationalization of Intra‐Team Communication in Sports: An Updated Version of the Scale of Effective Communication in Team Sports (SECTS‐2)

Sullivan & Feltz (2003 ) offered a preliminary multidimensional measure of communication in team sports, the Scale for Effective Communication in Team Sports (SECTS). The current research attempted to further the development and support for the psychometric properties and validity of the measure. In one study, 350 athletes completed an updated version of the SECTS. Confirmatory factor analyses showed good support for the 4‐factor structure. Correlations to team cohesion offer construct validity for the scale. A second study, with an independent sample (N = 79), revealed that team performance was negatively related to the communication of Distinctiveness at the team level. This updated version of the SECTS represents a parsimonious, valid, and reliable operational definition of sports‐specific effective team communication.     

Predicting Athletic Performance with Self- Confidence and Somatic and Cognitive Anxiety as a Function of Motor and Physiological Requirements in Six Sports

The purpose of the present study is to examine the ability of certain psychological attributes to predict performance in six National Collegiate Athletic Association Division I collegiate sports. Eighty-four athletes from the varsity sports teams of cross country running, alpine and nordic skiing, tennis, basketball, and track and field at the University of Colorado completed a questionnaire adapted from Martens (1977; Martens et al., 1983) that measured their trait levels of self-confidence (Bandura, 1977), somatic anxiety, and cognitive anxiety (Martens, 1977; Martens et al., 1983). In addition, at three to six competitions during the season, the members of the cross country running and tennis teams filled out a state measure (Martens et al., 1983) of the three attributes from one to two hours prior to the competition. Following each competition, subjective and objective ratings of performance were obtained, and, for all sports, coaches' ratings of performance and an overall seasonal team ranking were determined as seasonal performance measures. The sports were dichotomized along motor and physiological dimensions. Results indicate that all three psychological attributes were significant predictors of performance in both fine motor, anaerobic sports and gross motor, aerobic sports. Further, clear differences in these relationships emerged as a function of the dichotomization. In addition, unexpected sex differences emerged. The findings are discussed relative to prior research and their implications for future research.     

Transformational leadership and team performance in sports teams: A conditional indirect model

This study tests how transformational leadership fosters team performance through team cohesion and how that relationship is moderated by previous team performance and leadership consensus. We computed a moderated-mediation model based on a sample of 690 professional players in 59 top professional teams in interactive team sports leagues (basketball, handball, roller hockey, and indoor football/soccer) in Spain. Our findings suggest that transformational leadership indirectly influences objective team performance through the mediation role of team cohesion and that this indirect effect is more prominent when the level of previous performance is higher. We also found that the indirect effect of transformational leadership on team performance via cohesion is stronger in teams with higher consensus regarding their coaches' leadership. Overall, our results demonstrate the importance of integrating dispersion and contextual variables into research models, in particular, previous performance and leadership consensus.     

The differential effect of team members' trust on team performance: The mediation role of team cohesion

This study examines team performance as affected by various trusting relationships: trust between team members and the team's trust in their direct manager and in top management. Data for the study were collected from a survey of 690 professional elite athletes (belonging to 59 different sports clubs) playing in the regular, top professional Spanish leagues. The model was tested at the team level. Findings reveal that team member trust with respect to the different foci has both a direct and indirect effect on team performance, and that team player trust and cohesion play a mediating role. This study illustrates the dynamic relationship within teams, and, as such, trust among teammates mediates the relationship between trust in the coach as well as team cohesion in determining team performance. The implications for managing teams in other contexts are also evaluated.     

Interpersonal dynamics in sport: The role of artificial neural networks and 3-D analysis

In previous attempts to identify dynamical systems properties in patterns of play in team sports, only 2-D analysis methods have been used, implying that the plane of motion must be preselected and that movements out of the chosen plane are ignored. In the present study, we examined the usefulness of 3-D methods of analysis for establishing the presence of dynamical systems properties, such as phase transitions and symmetry-breaking processes in the team sport of rugby. Artificial neural networks (ANN s) were employed to reconstruct the 3-D performance space in a typical one-versus-one subphase of rugby. Results confirm that ANs are reliable tools for reconstructing a 3-D performance space and may be instrumental in identifying pattern formation in team sports generally.     

Spectators' identification with French sports teams: a French adaptation of the sport spectator identification scale

Due to the works of Wann and colleagues, spectators' identification with teams has taken on a central role in the study of sports spectators' thought and behavior. However, no research in this area has measured identification with sports teams in the French context. Two studies attempted to develop a valid and reliable French version of the Sport Spectator Identification Scale (SSIS) developed by Wann and Branscombe in 1993 to measure team identification. In Study 1, 200 physical education students completed a French translation of the SSIS and several questions concerning their involvement, investment, and evaluation of the team's future performance. Results showed that the French translation of the SSIS is a reliable and one-dimensional instrument: strong relationships were found between identification with professional French teams and these variables. In Study 2, 143 physical education students completed the SSIS with a National sport team as the target team. Results confirmed the psychometric properties of the scale and indicated that persons who strongly identify with the National soccer team reported more involvement with the team and were more optimistic about future performances than persons low in identification.     

Box Scores and Bottom Lines: Sports Data Can Inform Research and Practice in Organizations

In this introduction to the Special Issue on the use of sports data to inform research and practice in organizations, we first outline the state of research in this flourishing area to provide the need for this Special Issue. We note a similarity in the study of organizations and the study of sports and, in turn, how studies of sports can readily be compared to and applied to the study and practice of work in organizations. Next, we describe each of the six articles in this Special Issue, particularly noting that the articles sampled data from a variety of sporting domains, ranging from the National Football League to Olympic ice hockey. Topics of the studies included travel stress on team performance; pay standing and task performance; job hopping, organizational change, and performance of new employees; team work experience and performance; the effect of leadership transitions and changes to performance and human capital quality; and the effects of star performers and core team members. We then outline how these studies fit with the call for this Special Issue and provide common themes, such as methodological sophistication and novel analyses and the opportunity for sports data to provide both academic and practitioner audiences an awareness of evidence-based approaches to studies of work. We end this introductory article by providing some challenges in using sports data to enhance the study of organizations and possible areas for future research.     

Manual laterality and hitting performance in major league baseball.

Asymmetrical hand function was examined in the context of expert sports performance: hitting in professional baseball. An archival study was conducted to examine the batting performance of all Major League Baseball players from 1871 to 1992, focusing on those who batted left (n = 1,059) to neutralize the game asymmetry. Among them, left-handers (n = 421) were more likely to hit with power and to strike out than right-handers (n = 638). One possible account, based on the idea of hand dominance and an analogy to tennis, is that batting left involves a double-handed forehand for left-handers and a weaker and more reliable double-handed backhand for right-handers. The results are also interpretable in the light of Y. Guiard's (1987) kinematic chain model of a between-hands asymmetrical division of labor, which provides a detailed account of why left batting is optimal for left-handers.     

The team role test: development and validation of a team role knowledge situational judgment test

The main objectives in this research were to introduce the concept of team role knowledge and to investigate its potential usefulness for team member selection. In Study 1, the authors developed a situational judgment test, called the Team Role Test, to measure knowledge of 10 roles relevant to the team context. The criterion-related validity of this measure was examined in 2 additional studies. In a sample of academic project teams (N = 93), team role knowledge predicted team member role performance (r = .34). Role knowledge also provided incremental validity beyond mental ability and the Big Five personality factors in the prediction of role performance. The results of Study 2 revealed that the predictive validity of role knowledge generalizes to team members in a work setting (N = 82, r = .30). The implications of the results for selection in team environments are discussed.     

An analysis of an optimal selection process for characteristics and technical performance of baseball pitchers

Selection of a qualified pitcher has relied previously on qualitative indices; here, both quantitative and qualitative indices including pitching statistics, defense, mental skills, experience, and managers' recognition were collected, and an analytic hierarchy process was used to rank baseball pitchers. The participants were 8 experts who ranked characteristics and statistics of 15 baseball pitchers who comprised the first round of potential representatives for the Chinese Taipei National Baseball team. The results indicated a selection rate that was 91% consistent with the official national team roster, as 11 pitchers with the highest scores who were recommended as optimal choices to be official members of the Chinese Tai-pei National Baseball team actually participated in the 2009 Baseball World Cup. An analytic hierarchy can aid in selection of qualified pitchers, depending on situational and practical needs; the method could be extended to other sports and team-selection situations.     

The home advantage in individual sports: An augmented review

ObjectivesIs the home advantage in individual sports comparable in magnitude and consistency to that in team sports? If not, is it nevertheless a major factor? The present paper reviews the literature to date with respect to these questions and augments it with original analyses where appropriate.DesignThe review is framed and dominated by a design consideration, namely, that all major team sports play balanced home-and-away schedules, whereas individual sports rarely, if ever, do. As a result, it is necessary to take player quality into account in assessing home advantage in an individual sport.Method/approachThe paper begins with three individual sports (tennis, golf, and boxing) in which home advantage has been studied using available controls for player quality. It moves on to individual and team sports in the Olympics, where home advantage has also been studied with credible controls on player (country) quality. Studies are then reviewed in which player quality has not been controlled. Finally, data are presented for two individual efforts embedded in team sports (free throws in basketball and shootouts in ice hockey).ResultsSubjectively evaluated sports such as diving, gymnastics, or figure skating usually show sizable and significant home advantages. Otherwise, occasional findings have been reported but they are not consistent within a sport, are generally weak, and often statistically unreliable.ConclusionsExcept for subjectively evaluated sports, home advantage is not a major factor in individual sports, much less does it play a role in individual sports comparable to its role in team sports.     

SELECTING INDIVIDUALS IN TEAM SETTINGS: THE IMPORTANCE OF SOCIAL SKILLS, PERSONALITY CHARACTERISTICS, AND TEAMWORK KNOWLEDGE

Although work is commonly organized around teams, there is relatively little empirical research on how to select individuals in team-based settings. The goal of this investigation was to examine whether 3 of the most commonly used selection techniques for hiring into traditional settings (a structured interview, a personality test, and a situational judgment test) would be effective for hiring into team settings. In a manufacturing organization with highly interdependent teams, we examined the relationships between social skills, several personality characteristics (Conscientiousness, Extraversion, Agreeableness, and Emotional Stability), teamwork knowledge, and contextual performance. Results indicate that each of these constructs is bivariately related to contextual performance in a team setting, with social skills, Conscientiousness, Extraversion, and teamwork knowledge incrementally predicting contextual performance (with a multiple correlation of .48). Implications of these results for selection in team and traditional settings are discussed.     

高技术工作团队的交互记忆系统及其效果

交互记忆系统近来被认为是影响工作团队绩效的重要特性之一。以往的研究局限于实验室样本或者由学生组成的临时团队,该研究从高技术企业中选取190个工作团队作为样本,考查了团队的交互记忆系统与团队中的其它现象之间的关系。研究除了发现Lewis的量表中有两个题目不理想外,还发现交互记忆系统与团队成员之间的信任、合作性目标导向具有显著的正相关,同时交互记忆系统与团队的工作绩效和凝聚力也具有显著的关系。该文在检验团队层次的现象时,通过计算团队成员在相应变量上得分的一致性(rwg)来检查加总分析的合理性,这是从事团队层次的研究中需要遵循的方法     

礼之用,和为贵?和谐管理理论视角下团队亲社会违规氛围对团队绩效的影响

当前关于亲社会违规行为的研究主要集中于个体层面,但实践和理论都表明我们有探究团队亲社会违规氛围的必要性。为此,本研究聚焦于团队亲社会违规氛围这一概念,以和谐管理理论为基础,分别引入团队和谐作为中介变量和团队互依性作为调节变量,探讨团队亲社会违规氛围对团队绩效的影响机制和作用边界。本文以74个团队和334名团队成员为研究对象,通过对三阶段所获取的数据进行分析,结果显示:(1)团队互依性对团队亲社会违规氛围与团队和谐的关系具有调节作用:当团队互依性高时,团队亲社会违规氛围对团队和谐的负向影响更强;(2)团队和谐对团队绩效具有显著的正向影响;(3)团队互依性调节了团队亲社会违规氛围通过团队和谐对团队绩效的间接效应:当团队互依性水平较高时,团队亲社会违规氛围通过团队和谐对团队绩效的负向效应会被增强。本研究证实了团队亲社会违规氛围对团队绩效的作用机制与边界条件,拓宽了亲社会违规行为和团队和谐的相关研究。     

SEX SIMILARITIES AND DIFFERENCES IN TYPES OF PLAY IN GAMES AND SPORTS

In two studies, 374 participants gave retrospective reports of their favorite games, toys, and hobbies (games) and of their favorite exercise and sports (sports) in elementary school, high school, and college. We tested Gilligan's (1982) expectation that more of males' play would be group activities played in public places, whereas more of females' games and sports would be home-based play in "intimate" dyads. Results showed that sex similarities and differences varied as a function of kind of play. For both sexes, games tended to be home-based and individual or dyadic play, however sports tended to be group, public-based play. Whereas team sports play was most frequent in childhood for both sexes and decreased in frequency from childhood into adulthood, the decrease in team, as compared to individual and dyadic, sports was significantly more dramatic for girls than for boys. The data indicated that whereas girls participate in a variety of types of play, boys' sports play is dominated by team activity across development. Thus, sex differences in the types of sports play provided the strongest support for Gilligan's hypothesis that socialization in team play may foster a reliance upon rights-based moral reasoning in boys.     

Determinants of evaluation of team performance

Abstract.— The purpose of this study was to examine factors affecting the evaluation of the achievement behavior of a group . Subjects were asked to play the role of team members who have to convey their feedback to the whole team right after the performance. 214 subjects (males and females, high and low achievers) evaluated the achievement behavior of a group, a sports team. They were given knowledge of the group's performance outcomes (5 outcomes from clear win to clear loss), of the group's ability (yes or no) and of the effort (yes or no) expended by the group members. These factors yielded the 20 situations judged by each subject. In addition, half of the subjects evaluated a team performing under conditions of high competition and half under conditions of low competition. The results revealed that effort and outcome form major determinants of achievement judgments, but effects of these determinants depend on the joint influences of effort, outcome and ability. Need for achievement level of subjects and the type of situation did not affect achievement judgments. Overall, females were more rewarding among themselves than males in their own groups.     

TRAINING TEAM PERFORMANCE-RELATED ASSERTIVENESS

The present paper extends the existing literature on assertiveness in a way that supports industrial training as well as the selection of individuals for team positions. Data are reported from three studies that examined determinants of team performance-related assertiveness. First, data from 149 college students demonstrated that assertiveness consists of multiple dimensions which were not all related to performance in a team decision-making task. Second, data obtained from 225 business students indicated that correlations among self-report measures and peer ratings of the same assertive responses assigned by intact team members varied according to the interpersonal context (i.e., personal, stranger, work related) in which scale items were framed. Third, data from 60 college students suggested that team performance-related assertiveness has a significant skill component. Whereas both attitudinally focused and skill-based training improved attitudes toward team member assertiveness, practice and feedback were essential to producing behavioral effects. Implications for selection and team training are discussed.
