在再认记忆任务中，刺激可以被归类为“老”的基础上，准确的记忆或偏见，以响应“老”，但偏见在认知神经科学文献很少受到关注。在这里，我们研究了事件相关脑电位（ERP）的偏见相关的影响的模式和时间，以确定是否偏见更多地与记忆提取或响应验证过程。参与者被分为高偏差和低偏差组，根据他们的偏见，以回应'老'。这些组在识别准确性或ERP模式上没有差异，实际上是旧的与新的项目（客观旧/新效应）。然而，当旧/新的区别是基于每个主题的角度，即当项目判断为“旧”与那些判断为“新”（主观旧/新效应），显着的组差异观察到前额叶部位的时间（300-500毫秒刺激后）更符合偏见早期记忆检索过程比检索后响应验证过程。在标准的旧/新效应（命中与正确拒绝）中，这些组间差异介于客观和主观比较的组间差异之间，表明此类比较受到应答偏倚的混淆。我们认为，这些偏见是由前额叶皮层区域介导的自上而下的控制过程。
In recognition memory tasks, stimuli can be classified as ‘old’ either on the basis of accurate memory or a bias to respond ‘old’, yet bias has received little attention in the cognitive neuroscience literature. Here we examined the pattern and timing of bias-related effects in event-related brain potentials (ERPs) to determine whether the bias is linked more to memory retrieval or to response verification processes. Participants were divided into a High Bias and a Low Bias group according to their bias to respond ‘old’. These groups did not differ in recognition accuracy or in the ERP pattern to items that actually were old versus new (Objective Old/New Effect). However, when the old/new distinction was based on each subject’s perspective, i.e. when items judged ‘old’ were compared with those judged ‘new’ (Subjective Old/New Effect), significant group differences were observed over prefrontal sites with a timing (300–500 ms poststimulus) more consistent with bias acting early on memory retrieval processes than on post-retrieval response verification processes. In the standard old/new effect (Hits vs Correct Rejections), these group differences were intermediate to those for the Objective and the Subjective comparisons, indicating that such comparisons are confounded by response bias. We propose that these biases are top-down controlled processes mediated by prefrontal cortex areas.
