中文摘要:
      系统地探讨与研究了以汉语为母语的右利手被试者对汉语普通话声调感知的偏侧优势。选取40个常用的汉语普通话单音节词作为实验材料,在合适的反应时间和信噪比下采用双耳分听范式进行声调辨别听觉感知实验。实验要求被试者从同时、分别播放到左右耳的不同声调中选出一个最清楚听到的声调,而不考虑所选的声调来自左耳还是右耳。30位听力正常的右利手被试者参与了此项实验。实验结果表明,在本研究设定的双耳分听实验条件下,汉语为母语的右利手被试者对汉语普通话声调的感知存在显著的右耳(大脑左半球)优势,且对四个声调的感知具有相同的偏侧优势;左、右耳对四个声调间感知差异的趋势基本一致,且对3声的感知显著较其余声调差。
英文摘要:
      The lateralization of Mandarin tone perception of right-handed native Chinese Mandarin speakers was systematically investigated and discussed. Forty daily-used Mandarin monosyllables were utilized as experimental materials. The experiment was designed according to the dichotic listening paradigm under appropriate response time (RT) and signal-to-noise ratio (SNR). The subjects were asked to select one tone which was more clearly heard by both ears, regardless of the lateral. Thirty right-handed adult subjects with normal hearing were recruited for this study. Experimental results indicate that there was significant right ear advantage (REA) or left hemisphere lateralization on Mandarin tone perception. Moreover, same lateralization trend is found in all of the four Mandarin tones. The results also show that the perceptual difference trend for the four tones is the same for both ears, and the perception of Tone 3 is found to be significantly difficult compared with the rest three tones.
