Have you ever thought, “I wonder why she did that?” Or perhaps, “Why did I do that; it makes no sense.” If you have, then you are asking psychological questions. Most people enjoy being “students of human behavior” and observing and thinking about peo- ple, human nature, and all of the variants of the human condition. The difference between “most people” and psychologists is that the psycholo- gist hasspent manyyears in school studying andlearning about people. In addition to studying and doing research, psychologists also work directlywithpeopleinmanysettings.Forexample,clinicalandcounseling psychologists work with people who are dealing with psychological disor- ders or are having problems in their lives that require professional assis- tance, but there are many other branches of psychology as well. Sport psychologists work with athletes and teams to improve performance and team functioning. Industrial/organizational psychologists help workers, managers, and organizations function more effectively and efficiently. Military psychologists deal with military personnel and organizations.
