Abstract: In dichotic listening, a right ear advantage reflects left hemisphere specialization, and a left ear advantage reflects right hemisphere specialization. A dichotic listening task 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.

Key words: dichotic listening, right ear advantage, direct access model, callosal relay model
