Abstract:: Abstract: Objective To investigate whether there are changes in the components of event-related potentials, N200 and P300, as well as inhibition control ability in adolescent smokers aging from 18 to 25 years old based on Go/NoGo task. Methods Electroencephalogram (ECG) was collected from 30 adolescent smoker and 30 adolescent non-smokers performing Go/NoGo task. The amplitude of event-related potentials and task performance of adolescent smokers and non-smokers were compared. Results The P300 amplitude of adolescent smokers was significantly lower than that of the non-smokers (t=-2.357, P=0.023), and there was no significant difference in N200 amplitude (t=-0.904, P=0.375). The number of NoGo errors in adolescent smokers was significantly higher than that in the non-smokers (t=4.316, P=0.000). Moreover, Pearson correlation analysis showed that there was significant correlation between P300 amplitude and number of NoGo errors in adolescent smokers (r=0.37, P=0.044). Conclusion Compared with adolescent non-smokers, adolescent smokers have defects in inhibitory control ability. The study provides not only a certain reference for the study on smoking addiction of adolescent smokers, but also some help for medical staff and psychological counselor engaging in the treatment of smoking addiction.
