汉语普通话声调加工的右耳优势及其机理:一项双耳分听的研究

RIGHT EAR ADVANTAGE FOR MANDARIN TONE PERCEPTION AND ITS MECHANISM: A DICHOTIC LISTENING STUDY

采用双耳分听的任务探讨了汉语普通话声调加工的右耳优势问题 ,并引进反应手的因素 ,探讨了汉语声调加工的右耳优势的机制。结果表明 ,汉语母语被试对普通话声调的加工存在右耳、左脑优势 ,但这种优势是相对的 ,右脑也具备加工声调信息的能力 ,结果支持了直接通达模型。

In dichotic listening, a right ear advantage reflects left hemisphere specialization, and a left ear advantage reflects right hemisphere specialization. A dichotic listening task was used to investigate the brain lateralization of Mandarine tone. A response hand factor was manipulated to distinguish direct access and callosal relay explanations of perceptual asymmetry of Mandarine tone. The results indicated a right ear advantage or left hemisphere superiority for the perception of Mandarine tone and supported direct access model in the perception of Mandarine tone.
