Imagery has been shown to be an effective tool for enhancing performance in a variety of sports. Specifically, imagery has been found to be extremely effective within the sport of golf (e.g., Nicholls & Polman, 2005; Woolfork, Parish, & Murphy"s, 1985). For example, Ploszay, Gentner, Skinner, and Wrisberg (2006) found imagery to improve putting per...

The Multidimensional Model for Sport Leadership (MML) (Chelladurai, 1980) posits that an athlete’s performance and satisfaction are functions of the congruency between the preferred leadership of student-athletes, the required behavior of the coach as dictated by the situation, and the actual behavior of the coach. As such, research in sport should...
