Industrial and Organizational Psychology

Industrial and organizational psychology (also known as I/O psychology, occupational psychology, organizational psychology and work and organizational psychology) is an applied discipline within psychology. I/O psychology involves the scientific study of human behavior in the workplace and applies psychological theories and principles to organizations and individuals in their places of work. I/O psychologists are trained in the scientist–practitioner model. I/O psychologists contribute to an organization's success by improving the performance, motivation, job satisfaction, occupational safety and health as well as the overall health and well-being of its employees. An I/O psychologist conducts research on employee behaviors and attitudes, and how these can be improved through hiring practices, training programs, feedback, and management systems.

I/O psychology is one of the 15 recognized specialties in professional psychology in the United States. It is represented by Division 14 of the American Psychological Association (APA), known formally as the Society for Industrial and Organizational Psychology (SIOP). In the United Kingdom, industrial and organizational psychologists are referred to as occupational psychologists.
