Relevant studies have found that Internet addiction syndrome can cause different degrees of negative effects on people’s behavior and cognition, including people’s working memory ability. In addition, when we are addicted to something, the working memory can become extremely fragile, causing our thinking and learning ability to be affected. Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique that enhances human cognition and memory by affecting plasticity in specific brain regions through stimulation of different polarity. In this study, using the N-back paradigm and the left dorsolateral prefrontal cortex (lDLPFC) as the stimulus target, and the college students were divided into true stimulus group and pseudo-stimulus group. To explore the effect of transcranial direct current stimulation on the working memory ability of Internet addicts by comparing the accuracy and response of the two groups under different memory loads (0-back, 1-back, 2-back) before and after tDCS intervention. The results show that tDCS true stimulation can significantly improve the working memory ability of Internet addicted college students (reflected in the improvement of correct rate and the reduction of response), while the pseudo-stimulation group has no significant change. It is suggested that the left dorsolateral prefrontal cortex (lDLPFC) is a key brain region in working memory ability and can be used as a target for tDCS intervention.
