_Résumé : _
Research and theoretical developments on the theory of cognitive 
dissonance are reviewed. After considering the self-consistency, 
self-affirmation, and aversive consequences revisions, the authors 
review research that has challenged each of the revisions and that 
supports the original version of the theory. Then, the authors review 
the action-based model of dissonance, which accepts the original 
theory's proposal that a sufficient cognitive inconsistency causes 
dissonance and extends the original theory by proposing why cognitive 
inconsistency prompts dissonance. Finally, the authors present results 
from experiments examining predictions derived from the action-based 
model and neural processes involved in dissonance reduction.
