The purpose of a psychology major is to enable a student to interpret psychological theory utilizing scientific methodology in order to apply that knowledge to describe, analyze, predict, and shape human behavior. The study of psychology offers the opportunity to learn about the origins and development of human behavior and mental processes and the factors that influence change. Psychology provides a valuable foundation of knowledge important in a wide variety of fields, including human services, business, law, education, communications and health. The program in psychology may also lead to graduate preparation for professional psychology. The psychology major consists of 36 semester credits, with at least 18 credits in upper division coursework. (For all Illinois students, 24 or more upper division credits must be completed in the major.) In addition, students must complete the general education core.
