The scientific study of people whose thoughts and behavior deviate from accepted norms to such an extent that participation in and adaptation to normal situations is compromised.

Example: A college student relies heavily on the American Psychiatric Association’s Diagnostic and Statistical Manual (DSM) of psychological disorders when she studies for her Abnormal Psychology course.
