| Abstract: | From the angle or developmental psychology,this research explores the relationship between P300 and children's age characteristics. Our resultS are as follows: 1 ) P300 development ofthe children generally lended to be that the latency of the ERPdecreased with agel P3 Iatency obviously decreased with age;P3 amplitude increased with age. 2) The variation of P3 latency and amplitude among the six different age groups was significant. 3)Th. latency and amplitude of the ERP were not significant in different sex groups. |
