This book is designed to provide instructors and students in sport psychology courses with a learning instrument that combines the continuity of a textbook with the range of opinion, in-depth treatment of selected issues, and insight into research methods of a book of readings. The subject is divided into four topical categories. Under the heading of "Affiliation and Sport," social interaction, group behavior, and the psychology of teamwork are discussed. "Motivation and Sport" deals with the emotional factors in the performance of athletes. The third major topic, "Aggression and Sport," examines hostility and violence, their impact and how they may be controlled to improve performance. In the final section, "Personality and Sport," the personality traits of individual athletes are analyzed. (JD)
