Auditory processing is an important component of cognitive development, and names are among the most frequently occurring receptive language stimuli. Although own name processing has been examined in infants and adults, surprisingly little data exist on responses to own name in children. The present ERP study examined spoken name processing in 32 children (M=7.85years) using a passive listening paradigm. Our results demonstrated that children differentiate own and close other's names from unknown names, as reflected by the enhanced parietal P300 response. The responses to own and close other names did not differ between each other. Repeated presentations of an unknown name did not result in the same familiarity as the known names. These results suggest that auditory ERPs to known/unknown names are a feasible means to evaluate complex auditory processing without the need for overt behavioral responses.
听觉处理是认知发展的重要组成部分,而名字是最常出现的接受性语言刺激之一。尽管已经对婴儿和成人的名字处理进行了研究,但令人惊讶的是,关于儿童对自己名字的反应的数据却很少。本ERP研究采用被动听范式,对32名儿童(平均年龄7.85岁)的口语名字处理进行了研究。我们的结果表明,儿童能够将自己和亲密他人的名字与未知名字区分开来,顶叶P300反应增强就反映了这一点。对自己和亲密他人名字的反应彼此之间没有差异。重复呈现未知名字并不会产生与已知名字相同的熟悉感。这些结果表明,对已知/未知名字的听觉ERP是一种评估复杂听觉处理的可行方法,无需明显的行为反应。
