Are you anal retentive? How about orally fixated? This is a really fun student-centered way to engage your high school or college students in Sigmund Freud's theory of personality development. They take the simple questionnaire then calculate their own "scores" for their potential oral stage fixations and their potential anal stage fixations. Students always read the explanatory handout with great interest (since it may be revealing psychological secrets about themselves)--and in the process learn the details of Freud's famous theory. Includes a detailed page explaining the theory and the students' scores. Also includes a free-response assignment to accompany the activity as follow up. You can discuss the students' responses in class as closure.
