报道了171例3～6岁正常儿童的VEP各项指标的正常值。并对儿童VEP的左右半球、性别、年龄进行了差异性比较。结果发现3～6岁的VEP基本波型均已出现,但变异性大,稳定性差。此期不存在左右半球的显著差异,3～4岁VEP年龄差异较显著;而4～6岁则不明显,VEP的性别差异在儿童期存在。故VEP可做为儿童智能发展水平的一项客观指标。 The normal values ​​of VEP in 171 normal children aged 3 to 6 years were reported. And the left and right hemispheres of children’s VEP, gender, age were compared. The results showed that 3 to 6 years old VEP basic wave patterns have emerged, but the variability of large, poor stability. This period there is no significant difference between left and right hemisphere, 3 to 4 years old VEP age difference is more significant; 4 to 6 years old is not obvious, gender differences in VEP exist in childhood. Therefore, VEP can be used as an objective indicator of the level of development of children’s intelligence.
