听力正常及听力轻微损伤儿童语音感知的实验研究

An experimental research on the sound perception of children with normal hearing and mildly impaired hearing

本文采用实验方法研究听力正常及听力轻微损伤儿童感知单个音节的特点，并考察听力轻微损伤对单个音节感知的影响。实验结果显示，除了个别例外，不论是否有听力损伤，绝大多数被试都发生数量不等的语音感知错误。发生语音感知错误最多的语音成分是声母，其次是韵母，而声调的语音感知错误最少。被试的反应还表明语音感知过程包含大脑的处理活动。听力正常儿童与听力轻微损伤儿童反应结果的比较表明，听力轻微损伤对于单个音节的感知并没有造成显著的影响。

Abstract This experiment studied the characteristics of the perception of isolated syllables in the children with normal hearing and mildly impaired hearing.The research examined the impact of mild impairment in hearing on the perception of isolated syllables.The result indicated that incorrect perception of sound is common in both the children with normal hearing and the children with mildly impaired hearing.The initials were those that were mistaken most frequently in sound perception.The finals were less mistaken.And the tone was least mistaken.The responses of subjects also showed that the sound perception involved processing in the brain.Comparing the responses given by the children with normal hearing with those given by the children with mildly impaired hearing,we found that the mild impairment had not made significant impact on the perception of isolated syllables.
