The description of their course is: “This course surveys questions about human behavior and mental life ranging from how you see to why you fall in love. The great controversies: nature and nurture, free will, consciousness, human differences, self and society. Students are exposed to the range of theoretical perspectives including biological, evolutionary, cognitive, and psychoanalytic. One of the best aspects of Psychology is that you are the subject matter. This makes it possible to do many demonstrations in lecture that allow you to experience the topic under study. Lectures work in tandem with the textbook. The course breaks into small recitations sections to allow discussion, oral presentations, and individual contact with instructors.“
