本研究探讨了选择性注意对违反音乐句法的神经反应的影响。向非音乐家播放音乐和弦进程，同时记录事件相关电位(ERPs)。五和弦的进展包括61%的和声预期节奏(I-I-6-IV-V-I)，26%的和声意想不到的节奏(I-I-6-IV-V-N-6)，13%的五个和弦中的一个和弦的强度在整个持续时间内减弱。在有注意力的情况下，受试者在检测到音量减弱时按下按钮进行反应；在无人在场的情况下，受试者获得阅读理解材料，并被指示忽略所有听觉刺激。对谐和异常的反应，两种注意条件下都能在150-300ms观察到早期前负波(EAN)，但注意状态的EAN幅度要大得多。第二次头皮负向偏转也在谐频偏转后380-600毫秒被发现；这种迟发性负向在注意状态下开始得更早。这些结果表明，注意对调和句法的神经加工有很强的影响。(C)2005 Elsevier B.V.保留所有权利。
The effects of selective attention on the neural response to the violation of musical syntax were investigated in the present study. Musical chord progressions were played to nonmusicians while Event-Related Potentials (ERPs) were recorded. The five-chord progressions included 61% harmonically expected cadences (I-I-6-IV-V-I), 26% harmonically unexpected cadences (I-I-6-IV-V-N-6), and 13% with one of the five chords having an intensity fadeout across its duration. During the attended condition, subjects responded by pressing a button upon detecting a fadeout in volume; during the unattended condition, subjects were given reading comprehension materials and instructed to ignore all auditory stimuli. In response to the harmonic deviant, an Early Anterior Negativity (EAN) was observed at 150-300 ms in both attention conditions, but it was much larger in amplitude in the attended condition. A second scalp-negative deflection was also identified at 380-600 ms following the harmonic deviants; this Late Negativity onset earlier during the attended condition. These results suggest strong effects of attention on the neural processing of harmonic syntax. (c) 2005 Elsevier B.V. All rights reserved.
