音乐绝对音高信息加工的脑机制

音乐绝对音高(absolute pitch, AP)一直是音乐心理学者感兴趣的问题。AP能力是一种特殊的音乐能力。ERP研究表明具有AP能力的群体只需较少的认知资源进行音高加工, 同时不同AP能力的加工机制也不同; 功能神经成像研究表明大脑左侧额叶背侧后部和左侧颞叶平面对AP加工发挥重要作用; 脑结构研究发现AP群体的某些脑区皮层厚度低于没有绝对音高能力(Non-AP)群体, 这可能与AP特殊的加工机制有关。AP能力形成需要先天遗传和后天环境的共同作用, 其相互作用的脑机制需结合行为遗传学的研究方法及成果。

The Brain Mechanism of Musical Absolute Pitch Processing

Musical absolute pitch(AP) is an interesting perceptive for musical psychologists.ERP studies indicated that the population with AP ability adopted less cognitive resources to process musical pitch,meanwhile there were different processing mechanisms for different AP abilities.Functional neuroimaging indicated that left posterior dorsolateral frontal and left planum temporale played an important role in AP processing;brain structure studies found that the cortical thickness in some brain regions for AP popu...
