摘要
近年来,网络病态使用的一个子类—网络游戏成瘾已经引起了学术研究的兴趣。本研究采用修改的Stroop实验范式—Online Game Stroop探讨网络游戏成瘾者的注意偏向过程。结果发现,在网络游戏成瘾组中,网络游戏相关词语与中性词语相比诱发了更高的P200以及P300的振幅,但在正常对照组中未发现相同结果。此线索-反应证实了网络游戏成瘾者对特有的成瘾相关线索的高度敏感化引起的注意偏向可能是其成瘾行为产生和维持的重要基础。
In recent years,a subcategory of pathological internet use—＂online game addiction＂ has aroused academic attention.The online gaming addiction shares many negative impacts of substance addiction,such as failing at school,breaking family relationship and social relationship.Nevertheless,there was a lack of psychophysiological investigation about the underlying mechanisms to support the characterization of excessive online gaming as behavioral addiction. To investigate whether the attentional bias plays a crucial role in the development and maintenance of excessive online gaming,the authors obtained EEC data during a revised Stroop paradigm and during a color matching task using online game-related and neutral words in 12 online game addiction patients and 12 casual players. The behavioral data in the color matching task derived from both groups did not show a comparable interference effect related to the online game-related words.However,based on the analysis of the ERP data,we found that the online game-related words elicited significantly large amplitudes of P200 and P300 compared with the neutral words in the group of online game addiction patients,whereas there was no significant difference of amplitudes between cues of the online game-related words and neutral words for the group of casual online game players. These ERP results are discussed that in online game addicts online game-related word meanings would interfere with color matching, not only in an early,preconscious,automatic stage,but also in more conscious and controlled,motivation-related of attentional processing of information.The results indicated that the online game addicts were difficult to ignore the meaning of the colored words, and had to allocate more attention resources towards online game-related stimuli than to neutral stimuli.It can be concluded that online game addiction individuals display an enhanced attentional processing of online game-related stimuli,and this can be regarded as an expression of a greater responsiveness to onl
