网络游戏成瘾者注意焦点转换功能的特异性损伤研究

网络游戏成瘾对人类认知功能的损伤日益成为研究焦点之一。采用注意焦点转换任务，分别要求网络游戏成瘾被试与正常被试在工作记忆的语音环内、视空画板内及语音环——视空画板间进行注意焦点转换，然后比较两组被试在各转换任务中转换代价的差异，来探讨网络游戏成瘾者的注意焦点转换功能是否受损以及受损的特征。结果发现网络游戏成瘾组被试在视空画板内进行注意焦点转换时比对照组被试表现出更大的转换代价，而在其他两种转换任务中则没有发现组间差异。此结果表明网络游戏成瘾者的注意转换功能受到特异性损伤。

The Deficit Characteristics of Attentional Focus Switching Function in Online Game Addicts

The characteristic of cognitive deficits in the online game addicts is one of hot issues concerned by numerous researchers. Here, adopting the attentional focus task, we Required 14 game addicts and 14 normal participants to perform attentional focus switching task within phonological loop, within visuospatial sketchpad and between them, then compared the switching cost between two groups. The results showed that the switching cost was significant greater for game addicts than normal participants only in the task of switching within visuospatial sketchpad, however, no significant differences was found in the other switching task. These results indicated that there was a specific deficit on the attentional focus switching function for the online game addicts.
