众所周知，最初被认为是正确的，但后来被发现是错误的信息，尽管人们意识到撤稿，但往往会继续影响人们的判断和决策。然而，很少有研究调查这种现象的潜在神经基础，这种现象被称为“错误信息的持续影响效应”（CIEM）。目前还不清楚人类大脑是如何处理关键信息的。为了更详细地解决这个问题，26名健康的成年人在听简短的叙述时接受了功能磁共振成像（fMRI），这些叙述要么涉及收回先前的信息，要么不涉及。在每个叙述之后，研究对象对叙述的理解，包括他们依赖撤回信息的倾向。正如预期的那样，被收回的信息继续影响参与者的叙事相关推理。此外，功能磁共振成像数据表明，收回信息的持续影响可能是由于楔前叶和后扣带回实施的叙事级整合和连贯构建机制的破坏。
It is well known that information that is initially thought to be correct but then revealed to be false, often continues to influence human judgement and decision making despite people being aware of the retraction. Yet little research has examined the underlying neural substrates of this phenomenon, which is known as the 'continued influence effect of misinformation' (CIEM). It remains unclear how the human brain processes critical information that retracts prior claims. To address this question in further detail, 26 healthy adults underwent functional magnetic resonance imaging (fMRI) while listening to brief narratives which either involved a retraction of prior information or not. Following each narrative, subjects' comprehension of the narrative, including their inclination to rely on retracted information, was probed. As expected, it was found that retracted information continued to affect participants' narrative-related reasoning. In addition, the fMRI data indicated that the continued influence of retracted information may be due to a breakdown of narrative-level integration and coherence-building mechanisms implemented by the precuneus and posterior cingulate gyrus.
