Courses in Industrial/Organizational Psychology and Organizational Psychology From its first edition, two important themes have been the foundation of Ronald E. Riggio's Introduction to Industrial / Organizational Psychology. First, because I/O psychology is a field with both a strong scientific base and an applied orientation, the book demonstrates the connection between psychological theory and application: theoretical concepts are shown to lead to useful interventions. Second, this book was designed and written with the student in mind. Whenever possible, the text draws on examples and illustrations from the world of work that students understand - making for an introductory text that appeals to a wide range of students with varying academic backgrounds. This student-centered, real-world driven text demonstrates the connection between psychological theory and application in the field of Industrial / Organizational Psychology.
