During listening to a musical piece, unexpected harmonies may evoke brain responses that are reflected electrically as an early right anterior negativity (ERAN) and a late frontal negativity (N5). In the present study we demonstrate that these components of the event-related potential can be evoked preattentively, that is, even when a musical stimulus is ignored. Both ERAN and N5 differed in amplitude as a function of music-theoretical principles. Participants had no special musical expertise; results thus provide evidence for an automatic processing of musical information in onmusicians."
在聆听一段音乐作品时，意想不到的和声可能会引发大脑反应，这种反应会以早期右前负波（ERAN）和晚期额叶负波（N5）的形式在电信号上体现出来。在本研究中，我们证明了事件相关电位的这些成分可以在注意力前被诱发，也就是说，即使音乐刺激被忽略时也能诱发。ERAN和N5的振幅都因音乐理论原则而有所不同。参与者没有特殊的音乐专业知识；因此，研究结果为非音乐家对音乐信息的自动处理提供了证据。
