目的 比较纯音和汉语言语声刺激诱发的听觉事件相关电位(auditory event-related potentials,AERP)波形,探讨用汉语言语声刺激测试中国人AERP的可行性.方法 采用汉语言语和纯音作为声刺激对正常青年人(44名,83耳)进行AERP测试,对波形进行评分.比较言语和纯音声刺激诱发的AERP的潜伏期、幅值及波形评分.结果 言语声刺激比纯音更容易记录到典型AERP波形,差异有统计学意义(X2=4.0,P=0.039).分析言语及纯音刺激均记录到的72组AERP波形,言语和纯音刺激诱发的P3的潜伏期、幅值差异均无统计学意义(P>0.05),但言语诱发的AERP波形评分较纯音高(t=6.57,P=0.000).左耳言语刺激诱发的AERP的N2、P3潜伏期短于纯音,差异均有显著统计学意义(前者P=0.002,后者P=0.003),而右耳差异无统计学意义(P>0.05).结论 汉语普通话单词较符合AERP测试的要求和我国日常言语的习惯,汉语言语刺激较纯音可能更适合中国人的AERP测试.
目的 比較純音和漢語言語聲刺激誘髮的聽覺事件相關電位(auditory event-related potentials,AERP)波形,探討用漢語言語聲刺激測試中國人AERP的可行性.方法 採用漢語言語和純音作為聲刺激對正常青年人(44名,83耳)進行AERP測試,對波形進行評分.比較言語和純音聲刺激誘髮的AERP的潛伏期、幅值及波形評分.結果 言語聲刺激比純音更容易記錄到典型AERP波形,差異有統計學意義(X2=4.0,P=0.039).分析言語及純音刺激均記錄到的72組AERP波形,言語和純音刺激誘髮的P3的潛伏期、幅值差異均無統計學意義(P>0.05),但言語誘髮的AERP波形評分較純音高(t=6.57,P=0.000).左耳言語刺激誘髮的AERP的N2、P3潛伏期短于純音,差異均有顯著統計學意義(前者P=0.002,後者P=0.003),而右耳差異無統計學意義(P>0.05).結論 漢語普通話單詞較符閤AERP測試的要求和我國日常言語的習慣,漢語言語刺激較純音可能更適閤中國人的AERP測試.

Objective To compare the characteristics of auditory event-related potentials(AERP) evoked by pure tone stimuli and Chinese speech stimuli respectively,and to explore the feasibility of using Chinese speech stimuli to evoke AERP for Chinese.Methods AERP were tested by both Chinese speech and pure tone as stimuli in normal young participants(83 ears in 44 young postgraduate students),then each AERP wave form were scored.The latencies,amplitudes and scores of AERP evoked by speech stimuli were compared with by pure tone stimuli.Resuits Typical waves of AERP were recorded and identified more easily with speech stimuli than pure tone stimuli.moreover.the differences were statistically significance(X2=4.0,P=0.039).The latency and amplitude of P3 evoked by both Chinese speech stimuli and pure tone stimuli in the 72 ears were no significant difference(P>0.05).But the mean scores of AERP evoked by speech stimuli were significantly higher than those evoked by pure tone stimuli(t=6.57,p=0.000).N2 and P3 latency in left ear evoked by speech stimuli were significantly shorter than those evoked by pure tone stimuli(P=0.002,P=0.003).However there were no significant differences in right ear(P>0.05).Conclusions Chinese speech stimuli were more consistent with requests of AERP test and custom of Chinese spoken language,so the Chinese speech stimuli was more available for Chinese's AERP test than pure tone stimuli.
