| Nowadays,with the rapid development of society,the use of Internet and electronic products has integrated into the people of all ages in our country,adolescents have gradually become an important part of Internet user.However,the Internet not only has brought a variety of social conveniences,but also produced a part of the negative impact.Previous literature has shown that attentional deficits and Internet addiction are closely related,but few studies have assessed whether there is a correlation between Internet addiction and attention among adolescents.After reasonable preliminary experimental research and design,the purpose of the study is to explore whether there are potential obstacles in the attention function of Internet addicted adolescents,and to provide theoretical basis for the promotion and intervention of adolescent health education.In this study,IAT Internet Addiction Scale was used to screen the Internet Addiction Group and the normal group from a senior high school in Xi’an as the experimental subjects.Attention Network Task(ANT)and preview search task were used to measure the response time and accuracy of these subjects.The experimental data were sorted out and logged in SPSS software.The relationship between variables was examined by repeated measurement variance analysis and independent sample t test,and the relevant theoretical basis and social status were analyzed and summarized.In study 1,Attention Network Task(ANT)was used to find that:(1)Compared with the control group,there was no significant difference in response time between the Internet addiction group and the normal group,but the response time of the Internet addiction group was longer and the speed of target detection was slower.(2)By analyzing the indicators of attention network,we found that there were significant differences between the attention-oriented network and the control group,and there was no difference between the two networks,alarm and conflict.Study 2 used the preview search task to find that(3)Compared with the control group,the response time of the Internet addiction group was significantly different from that of the normal group,and the response time of the Internet addiction group was longer.There is a significant difference in error rate between the Internet addiction group and the normal group.The error rate of the Internet addiction group is higher.(4)Further analysis showed that there were significant differences in response time and error rate between the two groups under combined feature conditions and preview conditions.The response rate of Internet addiction group was significantly slower than that of the normal group,and the error rate was higher than that of the normal group.In this study,Attention Network Task(ANT)and preview search task were used to test the subjects’ bottom-up attention function and top-down attention function respectively.The results showed that the cognitive function of adolescents with internet addiction tended to be negative.The attention orientation function and selective attention of Internet addicted adolescents are deficient.Compared with the normal group,adolescents with internet addiction have a weaker ability to suppress impulse response tendency,and it is difficult to maintain a stable choice mode to react. |
