在一系列的实验中，颜色识别任务与词汇决策任务相结合。以相关颜色出现的词和非词诱发了注意相关事件相关电位（ERP）成分（前正性、后N2和N2b）。识别任务的结果，即调查单词的保留，与这些ERP组件的出现并不密切相关。这些发现表明，注意相关的ERP成分不是将词汇加工限制在相关颜色刺激的过滤机制的相关因素，而是后期选择过程的相关因素，确保了任务相关刺激的评估。
In a series of experiments, a color discrimination task was combined with a lexical decision task. Words and non-words that appeared in the relevant color elicited attention-related event-related potential (ERP) components (anterior positivity, posterior N2 and N2b). The results of the recognition tasks, that investigated the retention of the words, were not closely related to the emergence of these ERP components. These findings show that instead of being the correlates of a filtering mechanism confining lexical processing to stimuli in relevant color, the attention-related ERP components are correlates of late selection processes, ensuring task-related stimulus evaluation.
