The action-based model of dissonance and recent advances in neuroscience suggest that commitment to action should cause greater relative left frontal cortical activity. Two experiments were conducted in which electroencephalographic activity was recorded following commitment to action, operationalized with a perceived choice manipulation. Perceived high as compared to low choice to engage in the action, regardless of whether it was counterattitudinal or proattitudinal, caused greater relative left frontal cortical activity. Moreover, perceived high as compared to low choice caused attitudes to be more consistent with the action. These results broaden the theoretical reach of the action-based model by suggesting that similar neural and motivational processes are involved in attitudinal responses to counterattitudinal and proattitudinal commitments.
基于行动的失调模型和神经科学的最新进展表明，对行动的承诺应该会导致相对更大的左额叶皮质活动。进行了两项实验，通过感知选择操作来操作行动承诺，记录了随后的脑电图活动。与无论是否与态度相反的行动相比，感知到的高选择参与行动会导致相对更大的左额叶皮质活动。此外，与低选择相比，感知到的高选择会使态度更符合行动。这些结果通过表明类似的神经和动机过程涉及到对与态度相反和与态度一致的承诺的态度反应，拓宽了基于行动的模型的理论范围。
