Overview
Psychology is the study of the mind and behavior. The discipline embraces all aspects of the human experience — from the functions of the brain to the actions of nations, from child development to care for the aged. In every conceivable setting from scientific research centers to mental health care services, “the understanding of behavior” is the enterprise of psychologists.
Psychologists traditionally treat patients with mental and emotional problems, but they also serve as scientists researching the phenomenon of human (and non-human) behavior. They study how human beings relate not only to each other but also to machines, and they work to improve these relationships. In particular, they concentrate on behaviors that affect the mental and emotional health and mental functioning of healthy human beings.
In their research, psychologists follow scientific methods, using careful observation, experimentation, and analysis. They develop theories of human behavior and test them through their research. As this research yields new information, psychologists’ findings become part of the body of knowledge that practitioners call upon in their work with clients and patients.
Psychology is a tremendously varied field. Psychologists conduct both basic and applied research, serve as consultants to communities and organizations, diagnose and treat people, test intelligence and personality, and teach future psychologists and other types of students. With the rapidly increasing diversity of the U.S. population, psychologists bring important knowledge and skills to understanding different cultures.
There are many different careers within this profession. For example, psychologists work with business executives, performers, and athletes to reduce stress and improve performance. They advise lawyers on jury selection and collaborate with educators on school reform. Immediately following a disaster, such as a plane crash or bombing, psychologists help victims and bystanders recover from the trauma, or shock, of the event. They team with law enforcement and public health officials to analyze the causes of such events and prevent their occurrence.
