当个体被迫在相似的偏好选项中做出选择时，会产生负面的认知冲突，并且对被选择和被拒绝的选项的偏好态度会产生分歧。这种现象，通常被称为“认知失调”，是心理学和决策神经科学研究的兴趣。背侧前扣带皮层（dACC）参与表征由困难选择任务引起的认知冲突。先前的研究表明，dACC功能与年龄相关。然而，dACC在认知冲突方面的活动增强，以及行为上发生在年轻受试者中的选择诱导的偏好变化是否也发生在老年人中尚不清楚。此外，最近的研究已经注意到，在认知失调研究中经常使用的自由选择范式存在重大的方法论缺陷。在这里，我们使用功能性磁共振成像（fMRI）和修改后的自由选择范式正式测试的影响，选择引起的认知冲突的老化。在年轻的参与者中，行为数据证实了认知冲突的存在和对他们在困难选择试验中拒绝的替代品的偏好改变。成像数据显示，右侧dACC表现出与认知冲突相关的相互作用效应。相比之下，我们在老年参与者中没有观察到这种影响。这表明老年人可能感觉到较少的认知失调。
When individuals are forced to choose between similarly preferable alternatives, a negatively arousing cognitive conflict occurs, and the preference attitudes toward the chosen and rejected alternatives diverge. This phenomenon, often referred to as “cognitive dissonance”, is of interest in psychological and decision neuroscience research. The dorsal anterior cingulate cortex (dACC) is involved in representing the cognitive conflict induced by difficult-choice tasks. Previous studies have shown age-related decline of the dACC function. However, whether the heightened activity of the dACC regarding cognitive conflict, and choice-induced preference change that behaviorally occur in young subjects also occur in the elderly is unclear. Furthermore, recent studies have noted substantial methodological flaw with the free-choice paradigm that often used in studies focusing on cognitive dissonance. Here, we used functional magnetic resonance imaging (fMRI) and a modified free-choice paradigm to formally test the effect of aging on choice-induced cognitive conflict. In the young participants, behavioral data confirmed the existence of cognitive conflict and preference change for the alternatives that they rejected in the difficult-choice trials. The imaging data revealed that the right dACC displayed an interaction effect associated with cognitive conflict. In contrast, we did not observe such effects in the elderly participants. These suggest a possibility that elderly people likely feel less cognitive dissonance.
