摘　　要：研究发现网络成瘾者存在严重的“忽视长期利益、追求短期利益”的非理性决策行为.采用高精度tDCS技术干预网瘾被试和对照组,对比两组在最后通牒任务中的拒绝率和相应的反应时,发现单次20 min的右背外侧前额叶阳性刺激可以显著降低网瘾被试的拒绝率,并缩短其反应时间.研究结果说明,不仅单次高精度tDCS可促进网瘾者非理性决策行为的改善,而且通过干预关键脑区,即使是神经环路复杂的决策这一高级社会认知,高精度tDCS也可以实现对于决策整体加工的促进作用.因此,从其短时高效的作用效果出发,高精度tDCS未来可以考虑作为网瘾甚至更多其他病症的有效干预方法之一.Internet addicts exhibit a serious irrational decision-making behavior of“ignoring long-term benefits and pursuing short-term gains”.This study utilized HD-tDCS to intervene with internet addiction subjects and a control group,comparing their rejection rate and corresponding reaction times in the Ultimatum Game task.It was found that a single 20-minute positive stimulus on the right DLPFC could significantly reduce the rejection rate of internet addiction subjects and shortened their reaction times.Results indicated that not only a single HD-tDCS can promote the improvement of irrational decision-making of Internet addicts,but also by interfering with a key brain region,even in complex neural circuits involved in decision-making,HD-tDCS can facilitate overall decision processing.Therefore,considering its short-term and efficient effects,HD-tDCS could be as one of the effective intervention methods for internet addiction and even more conditions in the future.
