Psychology examines human behavior and cognitive processes. Contrary to popular perceptions, it does not consist of only psychotherapy, which is a sub- eld involving treat- ing clients via counseling sessions. To put it in another way, psychology in general is much broader. Psychologists do not receive medical training; hence they do not write prescriptions as physicians do. Instead, whether they work at a university, at a research center or in a clinical set- ting. they basically try to understand human behavior. Psychology studies a wide array of topics ranging from functions of the brain to social movements, from child development to the treatment of mental disorders. This extended horizon means that psychology has many different but interconnected subelds other than psycho- therapy. They include clinical psychology, developmental psychology, social psychology, cognitive psychology and psychometrics. More specific study areas include psychologies of law, sport, art, religion, industry, health, and education.
