The mismatch negativity event-related potential (MMN) was elicited in normal school-age children in response to just perceptibly different variants of the speech phoneme /da/. A significant MMN was measured in each subject tested. Child and adult MMNs were similar with respect to peak latency and duration. Measures of MMN magnitude (peak-to-peak amplitude and area) were significantly larger in children than in adults. The results of the present study indicate that the MMN can be elicited in response to minimal acoustic stimulus differences in complex speech signals in school-age children. The results support the feasibility of using the MMN as a tool in the study of deficient auditory perception in children.
错配负波事件相关电位（MMN）是在正常学龄儿童中诱发的，以响应语音音素/da/仅可察觉的不同变体。在每个受试儿童中均检测到显著的MMN。儿童和成人的MMN在峰值潜伏期和持续时间方面相似。MMN幅度测量值（峰峰值幅度和面积）在儿童中显著大于成人。本研究结果表明，在学龄儿童中，MMN可因复杂语音信号中最小的声学刺激差异而诱发。这些结果支持了将MMN用作研究儿童听觉感知缺陷工具的可行性。
