The exogenous components include P1, N1 and P2 waves, and the endogenous include N2 and P3 waves. The endogenous components are sensitive to psychological variables. There were a few of reports about ERPs of Characters of Chinese Words (CWW). We studied the ERPs and reaction time (RT) elicited by stimulation with CCW on adolescents and aged persons, and compared them with ERPs to tone and picture stimuli.展开更多
