用事件相关脑电位（ERP）研究了与记忆有关的名人和面孔识别减慢。在一组年轻人中，项目重复诱导早期（220-340 ms）和晚期（400-700 ms）ERP调制。显然分别用信号通知对面部和姓名的域特定表示以及关于这些人的域通用语义知识的访问。这些重复效应和其他ERP成分被用作中年和老年参与者的特定过程时间标记。对于面孔和名字，老年参与者的反应都很慢，但反应时间的重复启动却没有。事件相关电位（ERP）分析表明，大部分与年龄相关的减慢发生在特定领域表征的获取和反应决策过程中，而感觉和知觉加工在很大程度上幸免于难。
Age-related slowing in recognizing famous names and faces was investigated with event-related brain potentials (ERPs). In a group of young adults, item repetition induced early (220-340 ms) and late (400-700 ms) ERP modulations. apparently signaling the access to, respectively, domain-specific representations of faces and names and domain-general semantic knowledge about die persons. These repetition effects and other ERP components were then used as process-specific time markers in middle-aged and elderly participants. For both faces and names, the elderly participants' responses were slowed, but repetition priming in reaction times was not. The ERP latencies suggested that most of the age-related slowing occurred in the access to domain-specific representations and during response decision, whereas sensory and perceptual processing was largely spared.
