Psychology concerns the study and understanding of thoughts, feelings, and behavior. The courses offered by the department are directed toward the study and appreciation of the complex factors that influence behavior and covert experience in people and other animals, using methodology designed to enhance objectivity and responsibility. Studying psychology has a twofold function: (1) to further the intellectual development of the student; (2) to enhance preparation in professions within and related to psychology, such as clinical practice, research, counseling, education, social work, medicine, law, and business.

Major Requirements

The major consists of twelve 4-unit courses (48 units). Students may apply to the major and receive credit for upper-division coursework after having successfully completed Introduction to Psychology and Methods in Psychological Science. Majors select an academic advisor from among the department’s full-time faculty for consultation regarding their course programs. Though not strictly sequenced, the major is structured to provide both breadth and depth.

Students will satisfy the second-stage writing requirement by earning a letter grade of B- or better on the research paper assigned in PSYC 201: Statistics in Psychological Science. Students who do not earn at least a B- on this component of the course will revise their paper, subsequent to the course, until it meets that standard.


Senior majors must take and pass a comprehensive examination early in the semester that precedes graduation (i.e., spring of senior year for most students).


Honors in Psychology may be awarded to qualified students. Eligible students are those who have earned an overall college grade point average of 3.25 or better and a grade point average in Psychology of 3.5 or better, and completed an empirical project that demonstrates the student's psychological sophistication, intellectual creativity, and research skills, culminating in an APA-style manuscript. Only courses completed at Occidental are used to calculate grade point average. Consult the Psychology Department Moodle website for information pertaining to the honors proposal, thesis readers, enrollment expectations, and the evaluation process including critical dates.


The department will apply toward the psychology major most broad-based courses in Introduction to Psychology taken at accredited colleges and universities. 

Students with an Advanced Placement score of 4 or 5 on the Psychology examination or with an International Baccalaureate Psychology exam score of 6 or 7 will be placed out of Introduction to Psychology. 

In addition to Introductory Psychology, the department will accept a maximum of two psychology courses taken at other institutions and passed with grades of C or better toward the completion of the Psychology major. Please consult with your academic adviser and the department chair for course approval. 

Students transferring from another institution in the junior year or students who have taken a leave of absence for more than 1 semester may transfer Introductory Psychology and up to four other psychology courses, with approval from the department chair.
