学习口语的前提是有效的听觉功能。在目前的事件相关电位研究中，我们测试了是否以及如何基本的听觉过程与在线学习的语言规则在婴儿和成人。参与者听频繁的标准刺激，这是穿插与罕见的音高偏差和规则偏差，违反两个音节之间的非相邻依赖。只有对音高偏差表现出更成熟的失配反应的婴儿（即，负性）显示出对规则偏离者的不匹配反应。一致的是，一小群成年人谁表现出规则学习的证据表现出较大的不匹配效应的音高处理。我们的结论是，提取语言规则的能力在婴儿早期发展，并与基本的听觉机制的功能方面紧密相连。
Learning a spoken language presupposes efficient auditory functions. In the present event-related potential study, we tested whether and how basic auditory processes are related to online learning of a linguistic rule in infants and adults. Participants listened to frequent standard stimuli, which were interspersed with infrequent pitch deviants and rule deviants, violating a nonadjacent dependency between two syllables. Only infants who showed the more mature mismatch response for the pitch deviants (i.e., a negativity) showed a mismatch response to the rule deviants. Concordantly, the small group of adults who showed evidence of rule learning showed larger mismatch effects for pitch processing. We conclude that the ability to extract linguistic rules develops in early infancy and is tightly linked to functional aspects of basic auditory mechanisms.
