Psychology is the study of human and mental processes and behavior. It is both a biological and social science, a scholarly discipline, and a profession. Psychologists use many different methods and procedures and focus on a variety of problems, so psychology is a very diverse discipline, ranging from the neuroscientist studying brain behavior to the industrial/organizational psychologist studying the behavior of organizations.
Psychologists formulate and test theories using research and statistical methods in an effort to understand, predict and influence behavior. As a profession, psychology is dedicated to solving human–societal problems.
