Daniel M. Wegner, a pioneering social psychologist who is a professor of psychology at Harvard University, studies how we perceive and control our minds. He has done groundbreaking work in thought suppression and the nature of agency or conscious will. A graduate of Michigan State University, where he earned a baccalaureate degree and a Ph.D. in psychology in 1974, he began his teaching career at Trinity University in San Antonio, Texas, and was named a full professor in 1985. He moved to the University of Virginia as a professor of psychology five years later and was appointed to the William R. Kenan, Jr. Professorship in 1999. The next year he accepted his present position at Harvard. Dr. Wegner has been a visiting scholar at the University of Texas at Austin and a fellow at the Center for Advanced Study in the Behavioral Sciences in Palo Alto, California. His research has been supported by the National Science Foundation and is currently funded by the National Institute of Mental Health. A fellow of the American Association for the Advancement of Science, the American Psychological Association, and the American Psychology Society, he currently serves on the editorial boards of the Journal of Personality and Social Psychology, Consciousness and Cognition, Canadian Psychologist, and Psychological Inquiry and recently served on the board of reviewing editors of Science. Dr. Wegner has published more than one hundred articles in scientific journals and chapters in volumes of collected works. The co-editor of two books, he is the author or co-author of four others, including Implicit Psychology: An Introduction to Social Cognition (1977), (with Robin R. Vallacher) A Theory of Social Action Identification (1985), and White Bears and Other Unwanted Thoughts: Suppression, Obsession, and the Psychology of Mental Control (1989 and 1994). In his most recent book, The Illusion of Conscious Will, which was published by the MIT Press in 2002, he argues that the human feeling of free agency—the feeling that we consciously cause our actions—is created by the mind and the brain and serves as a guide to understanding ourselves, helping us to appreciate and remember our authorship of the things our minds and bodies do, and to developing a sense of responsibility and morality. He is currently preparing (with Daniel L. Schacter and Daniel T. Gilbert) a new textbook, Introduction to Psychology, which will be published by Worth.
