Thus, engineering psychology can also be described within the broader discipline of psychology, and within this the somewhat narrower discipline of applied psychology. In the latter the study of behavior is focused on the applications of those principles and theories of behavior and cognition to areas beyond the laboratory, such as industry schools, counseling, mental illness, and sports. Within this broader set o applications, the focus of engineering psychology tends to be on performance in the workplace(expanded to include transportation and some aspects of the home), hence characterizing its close linkage back to ergonomics, the study of work, and particularly cognitive ergonomics.
