不同程度手机网络过度使用者不同时程条件下注意偏向的特点

Attentional bias characteristics of different levels of over-users in mobile network under different time-course conditions

目的:探究不同程度的手机网络过度使用者,对消极情绪信息的注意偏向时程特点。方法:在河南省、湖北省各选取一所高校发放中文网络成瘾量表修订版(CIAS-R),获得有效问卷371份。依据CIAS-R评分标准筛选出手机网络使用正常组35人(CIAS-R得分<46分)、手机网络成瘾组31人(CIAS-R得分≥53分)、手机网络成瘾风险组32人(CIAS-R得分在46~53分之间)。采用50 ms、500 ms、1250 ms三个刺激呈现时程的空间线索提示范式,进行消极基本情绪词和消极自我意识情绪词注意偏向的测量。结果:刺激呈现50 ms时,手机网络使用正常组的消极基本情绪词的偏向分大于0(P<0.05);500 ms时,手机网络成瘾组的消极自我意识情绪词的偏向分大于0(P<0.05);1250 ms时,手机网络成瘾风险组的消极自我意识情绪词的回避分大于0(P<0.05),正常组的消极基本情绪词的回避分大于0(P<0.05)。结论:手机网络成瘾者与手机网络成瘾风险者的注意加工存在差异。

Objective:To explore the temporal characteristics of attentional bias to negative emotional information among over-users of mobile network in different degrees.Methods:The Revised Chinese Internet Addiction Scale(CIAS-R) was distributed in a university in Henan Province and one in Hubei Province,and 371 valid questionnaires were obtained.According to the scale scoring criteria,3 groups of subjects were selected to participate in the behavior experiment.The spatial cue paradigm of three stimuli presenting time,50 ms,500 ms and 1250 ms,was adopted to measure the bias of negative basic emotion and negative self-conscious emotion.Results:When the stimulus was at 50 ms,the bias score of negative basic emotional words in the normal group was greater than 0(P<0.05).At 500 ms,the bias score of negative self-conscious emotional words in the mobile Internet addiction group was greater than 0(P<0.05).At 1250 ms,the avoidance score of negative self-conscious emotional words in the mobile Internet addiction risk group was greater than 0(P<0.05).And in normal group,the avoidance score of negative basic emotional words was greater than 0(P<0.05).Conclusion:It shows that there are differences in attention processing between the mobile internet addicts and the mobile internet addiction risk group.
