The major in Psychology introduces students to the history and scope of psychological inquiry, helps them acquire a basic understanding of the scientific method and its application to psychological research, and trains them to critically evaluate and discuss psychological texts. They learn ways of thinking, knowing, and inquiring in more than one discipline through integrative courses. Psychology courses at Lang are taught primarily by faculty members of the graduate Psychology programs of The New School for Social Research (NSSR), some of whom hold joint appointments with Eugene Lang College. The Psychology department at NSSR is unusual for having both clinical and general psychology tracks and for a faculty that shares a sustained interest in understanding how culture and context influence individual adaptation and functioning. This applied approach to the subject influences the teaching of psychology at Lang.

Psychology majors have opportunities to work in a lab with a faculty member or graduate student or to assist with a research project of a faculty member or graduate student. Exposure and access to the faculty and resources of the graduate program in psychology is extensive. Advanced students are permitted to take selected graduate courses. Culture, cognition, context, and clinical topics feature prominently in the advanced psychology curriculum. Lang students also have access to clinical and research internship opportunities in New York City.

Upon successful completion of the major, students will have gained the skills and knowledge that will equip them for graduate study in psychology and other related fields, including education, law, social work, and management. Qualified students who plan to go on to graduate study in psychology, can apply for an accelerated BA/MA program in which they can apply credits earned in graduate level courses to both the bachelor's and the master's degree and so complete the MA in less than the usual two years.

Students can study psychology as a major (BA, Psychology), as a minor, or as part of a self-designed program (BA or BS, Liberal Arts).
