调式和速度组成的不同音乐形态诱发情绪活动的脑电研究——兼顾音乐训练经验和性别因素的表现特征

The Research of Brain Waves about Emotional Activity Induced by Different Musical Conformations Composing of Mode and Tempo:A Combined Representational Character of Musical Training Experience and Gender

该研究选取具有音乐训练经验和没有音乐训练经验的成年被试(研究生)共两组,每组男女数量各一半,使用脑电图(EEG)探讨了由速度和调式组成的不同音乐形态诱发情绪活动的脑电特征,结果表明:(1)在不同音乐形态上,小调音乐和慢速音乐诱发各脑区的δ、θ、β和γ四种波段的功率平均值均高于大调音乐和中速及快速音乐,只有α波的功率平均值低于大调音乐和中速及快速音乐;(2)所有音乐形态诱发音乐专业被试各脑区的功率平均值均高于非音乐专业被试,表明音乐训练经验导致了特殊神经网络参与加工;(3)所有音乐形态诱发男性被试各脑区的功率平均值均高于女性被试,表明两性在特异性信息加工方面具有神经解剖差异以及不同加工策略。

Selecting two groups of adult subjects(postgraduates) who had or didn't have the musical training experience,the number of man and woman in each group is separately one half,meanwhile using Electroencephologram(EEG) to investigate the brain wave's character of emotional activity induced by different musical conformations.The results indicate:(1) as to the musical conformations,the mean power values of δ、θ、β and γ induced by minor & slow tempo music in different brain areas are all higher than that of major and middle & fast tempo,only the mean power value of α is lower than them;(2) the subjects of music major's mean power values induced by all music conformations in different brain areas are higher than that of the no-major's,indicating that musical training experiences brings about the special process of neuron network;(3)men's mean power values induced by all music conformations in different brain areas are higher than that of women's,indicating that the two genders have divergent neuron anatomy and processing strategies on peculiar information process.
