Applied psychology is the use of psychological principles and theories to overcome problems in real life situations.
Mental health, organizational psychology, business management, education, health, product design, ergonomics, and law are just a few of the areas that have been influenced by the application of psychological principles and findings.
Some of the areas of applied psychology include clinical psychology, counseling psychology, evolutionary psychology, industrial and organizational psychology, legal psychology, neuropsychology, occupational health psychology, human factors, forensic psychology, engineering psychology, school psychology, sports psychology traffic psychology, community psychology, medical psychology.
In addition, a number of specialized areas in the general field of psychology have applied branches (e.g., applied social psychology, applied cognitive psychology).
However, the lines between sub-branch specializations and major applied psychology categories are often blurred.

This could be described as human factor psychology or as applied cognitive psychology.
