Psychology is the scientific study of behavior and mental processes. Psychology as a discipline and professional practice contributes to national development through basic and applied research and interventions aimed at solving problems and promoting optimal development and functioning of the individual, family, group, organizations/institutions, and the community, at national levels. The undergraduate programs in psychology prepare students for jobs that may involve training, testing, and research, and provide preparation for graduate studies in psychology as well as further studies in many other professions such as medicine, law, and business management.
