摘要： 目的考察学龄前儿童与成人汉语听觉失匹配反应(MMR)的特点。方法9 名学龄前健听儿童与8 名健听成人采用被动Oddball 模式进行事件相关电位测试，刺激为/bal/、/pal/辅音对。结果所有被试均诱发出明显MMR，成人表现为典型失匹配负波，学龄前儿童表现为宽大正向位移，出现的时间较晚，振幅较大。多因素方差分析显示，组别的主效应显著，学龄前儿童的MMR潜伏期长于成人，振幅大于成人(P<0.05)。结论获得了3~6 岁儿童和成人较为稳定、各具特点的MMR波形和指标值。

Abstract: Objective To investigate the features of the auditory mismatch response (MMR) elicited from the preschoolers and adults.Methods 9 preschoolers aged 3-6 and 8 adults were elicited and measured MMR to speech sounds (/bal/, /pal/) using the Oddball paradigm.Results The response was typical mismatch negativity in adults, and was slow positive waves with larger amplitude in the preschoolers.MNOVA results showed that there were significantly differences between the 2 groups, said the latency of MMRs was significantly longer and the amplitude was larger in the preschoolers than in the adults (P<0.05). Conclusion Stable MMRs with distinct characters in preschoolers and adults have been obtained respectively.
