Research Interests

Tactics of social influence; attributional processes; the interaction of personality and situational factors in social behavior; scale development of personality, attitudinal, and other self-report measures relevant to social behavior; psychological perspectives on the Holocaust.

Most recently my research interests have centered on the life and work of Stanley Milgram. This focus has three components: An experimental one, based on an attributional paradigm I developed using edited versions of the documentary film Obedience; analytic and integrative, in the form of review articles of research based on Milgram's work; and biographical/historical.
