摘要
采用线索探测范式,以攻击性词语、消极非攻击性词语和中性词语为实验材料,运用ERP技术考察了暴力电子游戏玩家注意偏向的脑神经机制.结果发现:与正常对照组相比,暴力电子游戏玩家对攻击性词语后靶子诱发的N1波幅增大;有效线索下,暴力电子游戏玩家对攻击性词语后靶子诱发的P300潜伏期减小.结果说明暴力电子游戏玩家对攻击性词语表现出了注意偏向,其机制为对攻击性词语的注意警觉.
Using the stimuli of aggressive words, negative non-aggressive words and neutral words, and combining the cue-detection paradigm with event-related potential （ERP）, the present study explored the neural mechanisms of attentional bias in players of violent video games. The results indicated that com- pared with non-gamers, garners showed larger amplitude of N1 and shorter latency of P30000 component to the detection target following the aggressive words. Compared with non-garners, garners ascribed more negative valence to the aggressive words. Gamers＇ attentional bias of aggressive words reflected attentional facilitation for aggressive words.
