摘要
音高感知是音乐感知研究领域的重要组成部分。该研究采用脑电技术,以钢琴与弦乐两种音色的音高作为刺激信息,对上海音乐学院演奏专业60名在校学生进行音高感知测试,旨在探究拥有绝对音高或相对音高的被试者在感知不同音色音高过程中的神经反应差异。研究结果显示,钢琴音色音高会导致更高的α频段聚类系数和更短的γ频段特征路径长度;绝对音高的被试其β频段聚类系数更高。皮尔逊相关性分析表明,β频段聚类系数与正确率呈正相关,γ频段特征路径长度与正确率呈负相关、与反应时呈正相关,γ频段聚类系数与反应时呈负相关。研究结果首次揭示α/γ/β频段活动特征与不同音色加工及音高判断正确率之间的关系。
Pitch perception is an important part of music perception research.Using EEG technology and pitch stimulus of piano timbre and string timbre,a pitch perception experiment was conducted on 60 students majoring in performance at Shanghai Conservatory of Music.This study aims to explore the differences in neural response when participants with absolute pitch(AP)or relative pitch(RP)processing pitches of different timbres.The results have showed that listening to piano tones causes a higher α-band clustering coefficient and a shorterγ-band characteristic path length than listening to string tones.AP participants have a higher β-band clustering coefficient than RP participants.Pearson correlation analysis has showed that theβ-band clustering coefficient positively correlates with the correct rate,theγ-band characteristic path length negatively correlates with the correct rate but positively correlates with reaction time,and theγ-band clustering coefficient negatively correlates with the reaction time.This study has revealed for the first time the relationship between the activity characteristics of the a/β/γband and the correct rate of pitch judgment of different timbres.
