信心较高的错误记忆比信心较低的记忆更有可能被反馈纠正(过度修正效应)。高置信度下的错误和低置信度下的正确反应都与较大的元记忆失配有关。因此，它们都代表了一种自动捕获参与者注意力的意外事件，因此通过反馈提供的正确信息被很好地编码。另一方面，一项衡量参与者感知到的项目实用价值的研究表明，自愿分配注意力可能涉及过度纠正效应。本研究以28名本科生为被试，通过事件相关电位(ERPs)的P3a/新颖性P3和P3b分别测量了自动和自愿注意分配。行为结果重现了词汇学习任务中的过度纠正效应，并显示出对感知实用价值的调节效应。此外，事件相关电位测量结果表明，注意资源的自动分配和自愿分配都独立地参与了过度纠正现象。
False memories endorsed with higher confidence are more likely to be corrected by feedback than those endorsed with lower confidence (hypercorrection effect). Errors made with high confidence and correct responses made with low confidence are both associated with large meta-memory mismatches. Therefore, they both represent a type of unexpected event which automatically captures participant attention, such that correct information provided via feedback is well-encoded. On the other hand, a study that measured participants’ perceived practical value for items suggested that voluntary allocation of attention might involve the hypercorrection effect. The present study involved a lexical learning task with 28 undergraduate student participants and measurement of automatic and voluntary attentional allocations via P3a/novelty P3 and P3b respectively, both of which are event-related potentials (ERPs). Behavioral results replicated the hypercorrection effect in a lexical learning task and showed modulation of the effect with regard to perceived practical value. In addition, ERP measurement results demonstrated that both automatic and voluntary allocations of attentional resources were independently involved in the hypercorrection phenomenon.
