Male Internet addicts show impaired executive control ability: evidence from a color-word Stroop task.

Author information

Department of Psychology, Zhejiang Normal University, PR China.


This study investigated the executive control ability of male students with Internet addiction disorder (IAD) by recording event-related brain potentials (ERP) during a color-word Stroop task. Seventeen IAD and 17 male normal university students participated. Behavior results showed that IAD students were associated with longer reaction time and more response errors in incongruent conditions than the control group. ERP results revealed that participants with IAD showed reduced medial frontal negativity (MFN) deflection in incongruent conditions than the control group. Both of the behavioral performance and ERP results indicate that people with IAD show impaired executive control ability than the normal group.
