Abstract：Objective To report speech evoked auditory brainstem responses(speech-ABRs)in preschool children(3-6 years old)to understand developmental characteristics of brainstem level auditory processing function and their cor-relation with language.Methods One hundred and four normal preschool children were recruited and divided into a 3-4 years old group(n=49)and a 5-6 years old group(n=55).All participants received speech-ABR test and their parents completed the Early Child Multiple Intelligences Rating Questionnaires-Speech-Language subscale.Results Laten-cies of waves V(6.60±0.21 ms)and A(7.62±0.28 ms)were shorter in the 5-6 years old group as compared to the 3-4 years old group(6.72±0.33 ms and 7.81±0.38 ms,respectively)(t=2.755,P=0.007 and t=2.723,P=0.008,respectively).Wave A amplitude was significantly higher in the 5-6 years old group(-0.15±0.06 μv)than in the 3-4 years old group(:-0.15±0.06 μv)(t=2.136,P=0.035).There was a positive partial correlation between wave A amplitude and language scores after controlling for gender and age(r=0.288,P＜0.05).Conclusion The synchronization ability of the auditory brainstem to speech stimulus coding in preschool children continues to develop,while the ability of phase-locking re-mains relatively stable,suggesting that subcortical auditory processing in preschool children is yet to mature,which is re-lated to language ability.
