即兴音乐创作认知过程研究——基于对脑成像实验的ALE元分析

A Study of Cognitive Processes in Music Improvisation——Based on ALE of Neuroimaging

即兴音乐创作是一种重要的音乐创作形式。目前,学术界对于即兴音乐创作神经机制的探索已经取得了一定的进展,但少有研究从音乐训练经验角度探究即兴音乐创作的认知加工过程及神经机制。因此,本研究采用ALE元分析方法,对117名具有不同音乐训练经验被试的110个脑区激活峰值进行比较分析。研究发现,音乐训练经验的差异会导致创作主体心理加工过程发生改变,致使其进行即兴音乐创造时脑区激活情况出现差异。

Improvisation is an important form of music creation.Currently,some progress has been made in exploring the neural mechanisms of music improvisation,but few studies have explored the cognitive processing process and neural mechanisms of it from the perspective of musical training ex⁃perience.Therefore,this study used ALE to comparatively analyze the activation peaks in 110 brain regions of 117 subjects with different music training experiences.It was found that differences in musical training experience lead to changes in the mental processing of creative subjects,resulting in differences in brain area activation when they engage in music improvisation.
