The current study on German investigates Event-Related brain Potentials (ERPs) for the perception of sentences with intonations which are infrequent (i.e. vocatives) or inadequate in daily conversation. These ERPs are compared to the processing correlates for sentences in which the syntax-to-prosody relations are congruent and used frequently during communication. Results show that perceiving an adequate but infrequent prosodic structure does not result in the same brain responses as encountering an inadequate prosodic pattern. While an early negative-going ERP followed by an N400 were observed for both the infrequent and the inadequate syntax-to-prosody association, only the inadequate intonation also elicits a P600.
目前这项针对德语的研究调查了与事件相关的脑电位（ERP），以了解对日常对话中不常见（即称呼语）或不恰当语调的句子的感知情况。将这些ERP与语法和韵律关系一致且在交流中频繁使用的句子的处理相关指标进行比较。结果表明，感知适当但不常见的韵律结构所引发的大脑反应与遇到不适当的韵律模式不同。虽然对于不常见和不适当的语法与韵律关联，都观察到了早期负向ERP随后是N400，但只有不适当的语调还会引发P600。
