Abstract
Objectives: It has been shown that attentional bias is important in the maintenance of addictive behaviors. However, existing research on the measurement of attentional bias in the Internet Gaming Disorder (IGD) is not sufficient. In this study, we aimed to develop an objective method of measuring attentional bias and to observe differences in attentional bias in the cases of excessive internet gamers.
Methods: Twenty-two male patients with IGD and sixteen age- and sex-matched healthy controls were examined with the eye tracking flanker task. Repeated-measures analysis of variance was performed to compare eye movement latency and fixation time between the two groups according to stimuli.
Results: Fixation time was significantly increased in patients with IGD compared to healthy controls. In the post-hoc analysis, fixation time in game related stimuli was significantly increased in patients with IGD. However, latency was not significant for all stimuli.
Conclusions: The results indicate that eye tracking flanker task could be an effective method to measure attentional bias in IGD patients. Future studies with a larger sample and more detailed methods could complement the findings of the current study.
