英文摘要：

17 aggressive children and the same number of normal children completed the auditory P300 task. The analysis of the P300 components revealed that the latency of P300 was longer, and the amplitude was smaller among aggressive children than normal children, indicating aggressive children had cognitive, especially attention deficits. The results of the present study also suggested that P300 could be used referentially as an objective index for identifying aggressive children.
