To study psychology is to understand behavior, both what people actually do and the mental processes underlying their actions. The psychologist s challenging job not only involves studying individuals and groups but also requires the researcher to take into account the environmental, physiological, and cultural factors that influence human behavior. Students of psychology employ a variety of clinical and scientific methods to discover how and why the human mind behaves as it does.
Psychology is a field that includes many vibrant areas of intellectual interest.
Clinical psychology studies normal personality as well as mental disorders and their treatment. Social psychology investigates significant social issues, and community psychology explores how community organizations develop to meet the changing needs of our society. Physiological psychology examines the biological bases of behavior, especially those involving the nervous system.
