摘要
音乐感知的脑电研究由来已久,研究相继发现了听觉诱发电位中的N1c、N2、P2及MMN或P3a皆与经过长或短期音乐训练后的神经元可塑性有关。而MMN与ERAN与人脑从音乐材料中提取规律性有关,二者皆是对期望违反的脑电反映,只不过ERAN多出现在和弦期望违背之中,而MMN更多的出现在音色、音程、节拍等声学特征的偏差中。另外,中晚期成份N5也被发现与和声、和弦整合有关,P600与音乐句法相关。音乐结构的复杂性与脑电设计的精简性间构成了该领域研究的基本矛盾,研究者们对各经典研究范式进行改进以演变出当前广为流行的音乐oddball范式、多种音乐MMN范式等。本研究旨在介绍音乐感知中主要脑电成份的基本背景及其研究范式,同时提出各个范式普遍存在的有关随机化、成份混淆、生态性等问题及相应的改进策略。
There has been a very long EEG study history about music perception, the previous studies had found N1c,N2,P2 component in the auditory evoked potential, The researchers also found that the MMN or P3a was associative with the neuronal plasticity after long or short term music training. Both MMN and ERAN involve extracting the regularity from music by brain, and are electrical potential reflection to the violations of expectation. The differences between ERAN and MMN are that ERAN was found frequently appearing in the violation of chords but MMN was more associative with the violations of acoustic feature such as timbre, interval and beat. Moreover, It had found that middle-late component N5 was relevant to the harmony and chord integration, also, P600 was concerned with music syntax. The complicated music structure and the requirements of cleanness and simplicity about the EEG research design has established the basic contradiction in the music conception research area. Researchers had modified the classical experimental paradigms to apply to the study of the music perception so as to the appearance of popular music oddball paradigm and MMN paradigm. This study mainly aimed at introduce the backgrounds and the experimental paradigms of the main components of music perception, while we raise the general questions that almost every paradigm existed such as the randomization, confounding components, and the ecological validity, and so on. Finally, we came up with some improvement strategies.
