绝对音高加工的认知神经机制
发布时间:2019-04-30 13:06
【摘要】:绝对音高(absolute pitch,AP)是一种比较罕见的音高加工能力,具有特殊的认知和神经机制。事件相关电位研究表明AP音乐家进行音高命名时,工作记忆参与较少但涉及多个认知策略。功能神经成像研究发现左侧额叶背侧后部和左侧颞叶平面对AP音乐家非常重要,而准AP音乐家(quasi-AP)的某些右侧脑区的参与则反映其增加的音高加工负荷和难度。结构神经成像研究发现AP音乐家具有特殊的灰质结构形态及白质连接。未来研究有待将AP能力进一步分为"具有相对音高能力"与"没有相对音高能力"两类并观察相应的认知神经机制,并通过影像基因组学来探索基因多态性对AP能力的影响,以及有必要观察以声调语言为母语的音乐家进行音高加工的神经机制。
[Abstract]:Absolute pitch (absolute pitch,AP) is a rare pitch processing ability with special cognitive and neural mechanisms. Event-related potential studies show that AP musicians have less involvement in working memory but more than one cognitive strategy in pitch naming. Functional neuroimaging studies showed that the left posterior frontal lobe and the left temporal lobe were very important for AP musicians, while the involvement of some right brain regions of quasi-AP musicians (quasi-AP) reflected their increased pitch processing load and difficulty. Structural neuroimaging studies show that AP musicians have special gray matter structure and white matter junction. In the future, the AP ability should be further divided into two categories: "relative pitch ability" and "no relative pitch ability", and the corresponding cognitive neural mechanism should be observed, and the effect of gene polymorphism on AP ability should be explored by image genomics. And it is necessary to observe the neural mechanism of pitch processing by native speakers.
