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.
基于行动的失调模型预测，在做出决策承诺后，会出现以趋近为导向的动机过程，以帮助将决策转化为有效且无冲突的行为。因此，对这些以趋近为导向的过程的调节应会影响个体改变态度以使其更符合决策承诺（替代方案的扩展）的程度。实验1表明，神经反馈引起的相对左额叶皮质激活的减少（这与趋近动机过程有关）导致替代方案扩展的减少。实验2在做出决策后操纵了一种以行动为导向的思维模式，并表明以行动为导向的思维模式导致左额叶皮质区域的激活增加以及替代方案扩展的增加。讨论集中在神经科学与失调理论的这种整合如何使两个母文献都受益。
