摘要目的 探讨正常人群中不同特质焦虑个体对负性汉语刺激的注意偏向特点.方法 采用点探测任务,使用汉语材料,比较不同特质焦虑个体(高焦虑组21、正常组20、低焦虑组21)在不同条件(负中词对、负正词对)下,对探测目标的反应时和注意偏向值差异.结果 当刺激为负中词对时,3组被试的注意偏向值与0差异有显著性[D1=(14.44±26.22)ms,t =2.401;D2=(12.05±19.89)ms,t =2.571;D3=(-13.14±24.07)ms,t =2.379;P <0.05];当刺激为负正词对时,只有低焦虑组和高焦虑组被试的注意偏向值与0差异有显著性[D4=(21.07±32.91)ms,t =2.791;D6=(-8.98±18.04)ms,t =2.170;P <0.05].结论 高焦虑被试对负性汉语存在注意偏向,低焦虑被试对负性汉语存在回避现象.

abstractsObjective To investigate the attentional bias for negative words in subjects with different trait anxiety.Methods The subjects with different trait anxiety (high anxiety:n =21,normal:n =20,low anxiety:n =21)participated in a dot-probe task.By compareing the reaction time and attentional bias under the probes replacing the words stimulus in different conditions,the subjects' attentional bias for negative word was examined.Results When the stimulus was negative-neutral words,the subjects all showed attentional bias and there was a significant difference to 0 value[D1=(14.44±26.22)ms,t =2.401;D2=(12.05±19.89)ms,t =2.571;D3=(-13.14±24.07)ms,t =2.379;P <0.05]. When the stimulus is negative-positive words,only the high- and low-anxiety groups show attentional bias and there was a significant difference to 0 value[D4 =(21.07±32.91)ms,t =2.791;D6=(-8.98±18.04)ms,t =2.170;P <0.05].Conclusion High trait anxious participants showed attentional bias to negative words,and low trait anxious participants showed attentional avoidance to negative words.
