To investigate the neural processing of different word categories, we recorded event-related potentials (ERPs) from 32 individuals listening to sentences, beginning either with a proper name (first name), the subject's own name, or a common noun. Names and nouns both elicited ERP waveforms with the same early componentry, but the N1 and P2 components were larger for proper names than common nouns. The ERPs to the subject's own name also had a large N1/P2 plus a prominent negativity at parieto-central site peaking around 400 ms and a late positivity between 500-800 ms over left lateral-frontal sites. These findings are consistent with differential processing of people's first names within the category of nouns.
为了研究不同词类的神经处理过程，我们记录了32名受试者在听句子时的事件相关电位（ERP），句子开头分别为专有名词（名字）、受试者自己的名字或普通名词。名字和名词均引发了具有相同早期成分的ERP波形，但专有名词的N1和P2成分比普通名词更大。受试者自己名字引发的ERP还具有较大的N1/P2，以及在顶中央部位约400毫秒达到峰值的显著负波，和在左侧额前部部位500 - 800毫秒之间的晚期正波。这些发现与名词类别中人们名字的差异处理是一致的。
