While behavioral differences in sport throughout the world are mainly attributed to sociological matters, various psychological issues shape the mind sets of athletes from different cultures. It is the way in which the individual's behavior reflects and is affected by different cultures that is the focus of this chapter. Cultural sport psychology provides much insight for coaches, athletes, and sport psychology practitioners to interact effectively with people throughout the world. Presently, cultural sport psychology research has largely been based on cultural awareness and understanding in order to improve the exchanges between people from different cultures. But the theoretical implications and psychological perspectives of how cultural differences evolve and the effects they have on the individual have not been fully addressed. What follows in this chapter is a theoretical approach from psychology to examining cultural influences on human behavior. Various concepts and psychological mechanisms such as identity, motivation, group dynamics, collectivism, individualism, self-complexity, and self-concept will be discussed. In the past, cross-cultural studies were generally viewed as a subcomponent of mainstream psychology and were generally not included in the literature. Today, however, cross-cultural studies report differences that are widespread, and make fundamental challenges to mainstream knowledge. Throughout history, a common thread ties much of this literature together, and that is its overwhelming concern with uncovering universal and culturally specific aspects of behavior. Newly discovered aspects will forge a path for cultural sport psychology to be integrated into mainstream psychology, shifting momentum in our thinking, and changing the way in which we study human behavior. We are already witness to these changes, as we are riding the wave of an evolution in sport psychology (Matsumoto, Weissman, Preston, Brown, & Kupperbusch, 1997; Schinke, Michel, Danielson, Gauthier, & Pickard, 2005). The evolution is critical because it strengthens existing connections among athletes and psychologists around the world, and develops new ways of cooperation among scholars and practitioners of sport psychology. The multidimensional roles of a sport psychology practitioner are to analyze, assess, explain, and direct various aspects of sport within the framework of psychological processes. According to the position statement of the European Federation of Sport Psychology (1996), the sport psychologist is interested in athletic well-being and augmenting human performance. This knowledge is then applied to either assessment or intervention. Application techniques such as talent detecting and cognitive testing in the former, and guidance and counseling in the latter. Sport psychologists study behavioral variations in athletes. Variations can be attributed to either individual differences such as personality dimensions, to environmental differences such as the social dynamics within the nature of the sport itself, or to cultural influences which not only have an impact on behavior, but may explain and predict it as well. Within the framework of cultural sport psychology, socio-cultural aspects of the athlete's environment need to be considered as a possible gateway leading to motivational skill refinement and revision (Schinke, Hanrahan, & Catina, 2009; Schinke, Michel, Danielson, Gauthier, & Pickard, 2005). Academic institutions that wish to incorporate multicultural training into the curricula of sport psychology students, and sport psychology practitioners can gain valuable insight by considering how socio-cultural factors shape the individual. A person's psychological shaping is a derivative of social contexts (Markus & Nurius, 1987). Simply put, one cannot be a self by one's self. In order to better understand different psychological mindsets of different athletes, an examination of the cultural basis of these psychological differences is necessary both within and across cultures. For example, Jasinskaja-Lahti, Liebkind, Jaakkola, and Reuter (2006) investigated the social support systems of different groups of immigrants and how variations of ethnic networks affected their well-being. Along with social support systems, myriad intermediary components are essential in transforming desire into action owing to the giant chasm that exists between elite athletes and their non elite counterparts. Dedication, persistence, self-regulation, optimism, mastery orientation, and the ability to endure the extreme pressure of elite competition are paramount to excellence in any sport. As one progresses in athletic skill level, one should never forget what it took to get there. Remember what it was like to think of sport endeavors as a beginner. The beginner's mind has many options, while the experts mind has few. It is in that beginner's mind where the theoretical implications of cultural sport psychology are grounded, and it is essentially the particular societal influences on the self-concept of athletes with which this chapter is governed.
