In addition to writing the textbooks Fundamentals of Abnormal Psychology (tenth edition), Abnormal Psychology (eleventh edition), Psychology Around Us (second edition), and Case Studies in Abnormal Psychology (third edition), Professor Comer has published a range of journal articles and produced numerous widely used educational video programs, including The Higher Education Video Library Series, The Video Anthology for Abnormal Psychology, Video Segments in Neuroscience, Introduction to Psychology Video Clipboard, and Developmental Psychology Video Clipboard.

Professor Comer was an undergraduate at the University of Pennsylvania and a graduate student at Clark University. He currently lives in Florida with his wife, Marlene. From there he keeps a close eye on his nearby grandchildren Delia and Emmett, somehow making the same mistakes with them that he made with their father Jon and their uncle Greg a generation ago. Then again, that turned out pretty well.
