Research Topics

One of Aronson's key areas of interest and research has been the theory of cognitive dissonance. Aronson is credited with refining the theory, which posits that when attitudes and behaviors are inconsistent with one another that psychological discomfort results. This discomfort motivates the person experiencing it to either change their behavior or attitude so that consonance is restored.

Aronson is famous for the Jigsaw Classroom experiment conducted in 1971. The experiment was aimed at identifying methods of reducing prejudice in the newly desegregated Austin school system. Classrooms using traditional individual competitive learning techniques were compared to those requiring cooperative learning in race-integrated groups. The cooperative learning groups were referred to as Jigsaw Groups and required that students rely on one another to succeed on exams. The results showed that compared to traditional classrooms, Jigsaw classroom students had lower levels of prejudicial attitudes and negative stereotyping. Group participants demonstrated higher self-confidence, lower absenteeism, and higher academic achievement than students in the competitive classrooms.

Elliot Aronson has authored many books including the popular textbook The Social Animal (ISBN 0716733129), currently in its ninth edition.
