采用双耳分听任务研究了音乐辅音中枢加工的左右不对称性。两个钢琴音以不同的音高间隔（1-11个高音）配对，每只耳朵呈现一个音符给20个绝对音高拥有者。结果发现，左耳优势（莱亚）的总体趋势较弱，这是受过训练的音乐家的特征。第二，不协和音程的音高比协和音程的音高更难辨认。最后，不协和音程的莱亚大于协和音程。由于音调是二分法呈现的，结果表明，中枢听觉系统可以区分协和和不协和间隔，而无需耳蜗中的音高关系的初始处理。(C)2003年爱思唯尔公司All rights reserved.
Left-right asymmetry in the central processing of musical consonance was investigated by dichotic listening tasks. Two piano tones paired at various pitch intervals (1-11 semitones) were presented one note in each ear to twenty absolute-pitch possessors. As a result, a weak overall trend for left ear advantage (LEA) was found, as is characteristic of trained musicians. Second, pitches of dissonant intervals were more difficult to identify than those of consonant intervals. Finally, the LEA was greater with dissonant intervals than with consonant intervals. As the tones were dichotically presented, the results indicated that the central auditory system could distinguish between consonant and dissonant intervals without initial processing of pitch-pitch relations in the cochlea.
