Résumé :
The action-based model of dissonance predicts that following decisional 
commitment, approach-oriented motivational processes occur to assist in 
translating the decision into effective and unconflicted behavior. 
Therefore, the modulation of these approach-oriented processes should 
affect the degree to which individuals change their attitudes to be more 
consistent with the decisional commitment (spreading of alternatives). 
Experiment 1 demonstrated that a neurofeedback-induced decrease in 
relative left frontal cortical activation, which has been implicated in 
approach motivational processes, caused a reduction in spreading of 
alternatives. Experiment 2 manipulated an action-oriented mindset 
following a decision and demonstrated that the action-oriented mindset 
caused increased activation in the left frontal cortical region as well 
as increased spreading of alternatives. Discussion focuses on how this 
integration of neuroscience and dissonance theory benefits both parent 
literatures.

Mots-Clés:
cognitive dissonance; action-based model; approach motivation; 
asymmetrical frontal cortical activity; neurofeedback
