What do psychologists do?
Psychologists teach, counsel, and work in research or administration to help understand people, their capacities, traits, and behavior and to explain their needs. They do this through interviewing and observing individuals, through testing, through the study of personal histories, and through controlled experiments. Psychologists normally hold doctorates (Ph.D., Psy.D., or Ed.D.) in psychology but they are not medical doctors, and cannot prescribe medication.
A doctorate in psychology (Ph.D. or Psy.D., doctor of psychology) is recommended for those who hope to make a career in the field. Psychologists do not need to attend medical school.
Psychologists who wish to enter private practice must meet certification or licensing requirements in all states and in the District of Columbia.
