研究人员对一只完全清醒的黑猩猩的大脑活动进行了研究。事件相关电位(ERPs)针对以下每个听觉刺激进行测量：受试者自己名字的声音(SON)、另一组成员熟悉的名字的声音、陌生名字的声音和非声音的声音。在人类中典型观察到P3和NC成分的潜伏期，不同类型的刺激在ERP波形上发现了一些差异。刺激开始后，观察到约500ms潜伏期的NC样负移，尤其是对SON的反应。这种特定的ERP模式表明，黑猩猩处理她的名字的方式与其他发音不同。
The brain activity of a fully awake chimpanzee being presented with her name was investigated. Event-related potentials (ERPs) were measured for each of the following auditory stimuli: the vocal sound of the subject's own name (SON), the vocal sound of a familiar name of another group member, the vocal sound of an unfamiliar name and a non-vocal sound. Some differences in ERP waveforms were detected between kinds of stimuli at latencies at which P3 and Nc components are typically observed in humans. Following stimulus onset, an Nc-like negative shift at approximately 500 ms latency was observed, particularly in response to SON. Such specific ERP patterns suggest that the chimpanzee processes her name differently from other sounds.
