Psychology is the scientific study of the mind and behavior. Psychologists are actively involved in studying and understanding mental processes, brain functions, and behavior.

A psychologist treats a patient through psychotherapy, helping to relieve symptoms through behavioral change.  Essentially, psychology helps people in large part because it can explain why people act the way they do. With this kind of professional insight, a psychologist can help people improve their decision making, stress management and behavior based on understanding past behavior to better predict future behavior.

All of this can help people have a more successful career, better relationships, more self-confidence and overall better communication.
