My major research focus is on attitudes and attitude change, particularly as they relate to the process of cognitive dissonance. My recent work examines the role of the vicarious experience of dissonance -- i.e., feeling dissonance due to the inconsistent behavior of others. I am also interested in the role of the self in dissonance arousal. Two other areas of active interest are (1) the effect of expert testimony in courts of law and (2) gender differences in the effectiveness of information technology, particularly among school children.
