ABSTRACT
Objective To investigate the change of the error positivity(Pe)of event-related poten-tial(ERP)under Flanker task in adolescents with smoking addiction. Method The signals of ERP during the Flanker task in fifteen adolescents with smoking addiction were compared with that of 15 non-smoking ad-olescents. Results The Pe amplitude in adolescents with smoking addiction((3.575±2.299)μV)was sig-nificantly lower than that of non-smokers((5.865 ± 4.290)μV)(F=5.324,P=0.029),and the reaction time of the Flanker task in smoking addiction adolescent group((440.754± 36.051)ms)was significantly higher than that in the control group((422.850±20.194)ms)(F=0.620,P<0.05).The Pe amplitude in ado-lescents with smoking addiction was positively correlated with smoking index(pack-years)(r=0.599,P=0.018). Conclusion The adolescents with smoking addiction may exit worse ability of error monitoring dur-ing the Flanker task.
