到目前为止，抑制的电生理学证据主要来自传统的检索诱导遗忘和思考/不思考范式，这些范式涉及对思维的策略性和有意性限制。在这里，使用一种新颖的任务来检查抑制的事件相关电位（ERP）特征，该任务与传统范式不同，不包括初始启动步骤或有意的思维限制。参与者被指示对提示词（例如，”披萨”），和其他无关的反应。根据抑制帐户的干扰决议，语义竞争自动激活的目标词必须解决，以产生一个不相关的反应，而没有决议是需要产生相关的反应。在随后的阶段中，目标词的可访问性（例如，“PEPPERONI”），不需要抑制的单词，以及新的控制词进行了测量使用词汇决策任务。我们观察到一个持续的晚期积极的无关反应的生成任务，和早期的负振幅的抑制项目的词汇决策任务。这些研究结果是一致的抑制机制在检索操作，以抑制竞争对手，并表明，这样的过程中操作的自动激活的项目，没有在实验的背景下，代表检索的情况下，发生在日常生活中。
The electrophysiological evidence for suppression to date primarily draws upon traditional retrieval-induced forgetting and Think/No-Think paradigms, which involve strategic and intentional restriction of thought. Here event-related potential (ERP) signatures of suppression were examined using a novel task, which unlike traditional paradigms, does not include an initial priming step or intentional thought restraint. Participants were instructed to verbally generate semantically related responses to cue words (e.g., “PIZZA”), and unrelated responses to others. According to an inhibitory account of interference resolution, semantic competition from automatically activated target words must be resolved in order to generate an unrelated response, whereas no resolution is required for generating related responses. In a subsequent phase, accessibility for target words (e.g., “PEPPERONI”) that required suppression, words that did not require suppression, as well as new control words was measured using a lexical decision task. We observed a sustained late positivity for unrelated responses in the generation task, and early negative amplitudes of suppressed items in the lexical decision task. These findings are consistent with inhibitory mechanisms operating at retrieval to suppress competitors and show that such processes operate on automatically activated items that are not presented in the context of an experiment, representative of retrieval situations that occur in everyday life.
