Subjects were assigned an assumed name and then shown a series of statements of the form, "My name / is / X", where X was the assumed name, their own first name, or one of a set of other false names. Their task was to respond positively to the "assumed" name and reject as false all other names, including their own. An N380 feature of the averaged task-related brain potentials, considered to be inversely related to the degree of contextual priming, was greatly enhanced for the false names compared to the assumed name. The N380 to one's own name was more similar to that of the false than the assumed name, indicating that the sentence context's priming of various names was under the subjects' attentional control, and that the late negativity could be modulated by this attention. In contrast, a large P510 feature distinguished one's own name from the false name, and this difference was unaffected by practice. Even in cases, then, where the context allows anticipation of one verbal event (here, the assumed name), a highly overlearned and salient stimulus such as one's own name continues to produce a distinctive neural response.
研究对象被赋予一个化名,然后看到一系列形如“My name / is / X”的陈述,其中X是化名、他们自己的名字或一组其他假名中的一个。他们的任务是对“化名”做出肯定回应,并将所有其他名字(包括他们自己的名字)判定为假而予以拒绝。平均任务相关脑电的N380特征被认为与情境启动程度呈负相关,与化名相比,假名的N380特征显著增强。与化名相比,对自己名字的N380更类似于对假名的N380,这表明句子语境对各种名字的启动受研究对象的注意力控制,并且晚期负波可以受这种注意力调节。相比之下,一个大的P510特征将自己的名字与假名区分开来,并且这种差异不受练习的影响。那么,即使在语境允许预期一个言语事件(这里是化名)的情况下,像自己名字这样高度过度学习且突出的刺激仍然会产生独特的神经反应。
