Cognitive Dissonance - Professor Eddie Harmon-Jones

What is this research about?

Cognitive dissonance theory is one of psychology’s most influential theories and one of the few instances of a cumulative social psychological theory. However, mechanisms underlying production of perceptual, cognitive, affective, and behavioural changes produced by dissonance are not well understood.

Understanding these mechanisms has both theoretical and practical implications. Because much past research had demonstrated problems with each revision of dissonance theory, Professor Harmon-Jones’ lab developed a new theory -- action-based model of cognitive dissonance -- that addresses the motivation underlying dissonance reduction.
