The impact of Internet Dependence on College Student's attention networks
2017, 25 (suppl.):
The experiment is aimed to explore the influence of attention networks in university students with Internet addiction. The experiment adopted 4(cue conditions:spatial cue, center cue, double cue, no cue) * 3 (flanker types: congruent, in-congruent, neutral) two-within-subject factors factorial design with 32 university student subjects.The subjects were randomly divided into two groups by YOUNG net-addition scale.16 low net-addition,16 moderate net-addition.Using ANT to evaluate the processing distinction within each of these three networks (Alerting, Orienting, and Executive control Function). We obtained the results: (1) in the group of moderate net-addition, The Alerting had a significant decrease;Executive control Function had a significant rise.There was no significant difference in Orienting Function .the mean RT of low net-addition was respectively 573.14ms,and the Accuracy rate of low net-addition was respectively 98.3. the mean RT of moderate net-addition was respectively 643.46ms, and the Accuracy rate of moderate net-addition was respectively 94.8. (2) The results of Repeated measures analysis of variance were: F cue conditions(3, 30)=22.452, P=0.000; F flanker types( 2, 30)=10.603, P=0.000.the main effect of cue and flanker types was significant .(3) The results of Paired Samples Test were:t=4.610,p=0.000, Alerting of moderate net-addition was strongly decrease; t=-1.147, p=0.026, Executive control Function of moderate net-addition was strongly increased; t=-1.852, p=0.084, Orienting function of subject was insignificant. (4) The main effect of Alerting and Executive control Function is strongly significant. but, The main effect of orienting function was insignificant. As was the conclusion: Alerting, Executive control Function of net-addition subject was abnormal, Orienting function was relatively stable.
