Abstract:
Objective To explore the effect of Internet addiction on adolescent's attention.Methods Neuropsychological evaluations of attention function were done separately in 18 adolescents who met the diagnostic criterion for Internet addiction and in other 18 ones without Intemet addition tendency as a control group. With auditory and visual oddball paradigms, and stimulated by standard,target and novel stimuli, EEG was recorded and analyzed to get the event-related potential P300 and compare the latency and amplitude of P3a and P3b between the 2 groups. Results Compared with the controls, the attention of Internet addiction group was decreased significantly in neuropsychological evaluations. The latency of P3a potentials induced by novel stimulus was much shorter and the amplitude of it was higher in addiction group than in control group, but the latency of P3b potentials generated by target stimulus was prolonged and the amplitude decreased obviously. Conclusions Intemet addiction can cause damage to adolescent's attention function. There is a correlation between the attention impairment and the change of P300 potentials.
