This updated fourth edition of Arnold LeUnes's textbook has comprehensive coverage of sport psychology with a healthy balance between theory and application. The strong applied approach is emphasized throughout but is essentially apparent in the second half of the book. The book features a strong pedagogical program including interesting applied vignettes, chapter outlines, emboldened key terms with glossary, very thorough chapter summaries, student-oriented suggested readings, and numerous tables and figures to visually summarize the key concepts. The book's shorter chapters make it easier to assign one per class. In addition, a website of supplemental resources, free of charge to qualified adopters, makes this new edition even more accessible and student-friendly.
