摘要
网络成瘾与吸烟、饮酒等物质成瘾具有许多相似性,因此也可能存在类似的认知偏向和神经机制。本研究采用事件相关电位技术,通过点探测范式研究网络游戏过度使用者的注意偏向问题。结果显示:(1)与一般使用者相比,网络游戏过度使用者存在明显的注意偏向;(2)游戏图片对网络游戏过度使用者诱发的P2的振幅小于一般使用者;(3)网络游戏过度使用者对游戏图片位置上出现的探测点的加工(P1)较早。结果提示,网络游戏过度使用者的注意偏向存在特定的脑电模式。
Internet addiction resembles substance addiction such as smoking and alcohol, and hence we assume that they may share similar cognitive bias and neural mechanism. The present study adopted the event-related potential recording technique and dot-probe paradigm to examine the attentional bias of heavy online game users. It was found that heavy internet users showed obvious attentional bias,lower amplitude of 1：＇2 evoked from game-related pictures than general internet users, and shorter latency of P1 elicited from the dot stimulus which emerged in the same side of the game-related pictures than that in the other side. It was indicated that heavy internet user＇ s attentional bias has special EEG pattern.
