高积极倾向个体对情绪声音的注意偏向——消失的返回抑制效应

Attentional Bias to Emotional Sounds in Positive-disposed Individuals:The Diminished Effect of IOR

目的:探索高积极倾向个体对情绪声音的注意偏向。方法:采用听觉版的线索—靶子任务范式,从返回抑制削弱的角度,在长SOA情况下考察了33名高积极倾向个体和27名低积极倾向个体对不同情绪效价声音的注意偏向(解除困难)。结果:高积极倾向个体在正性和负性声音下,线索有效与线索无效的反应时无显著差异,不存在返回抑制现象,表明高积极倾向个体对正性和负性声音均存在注意解除困难;而低积极倾向个体只在正性声音下存在返回抑制消失现象,即只对正性声音存在注意解除困难。结论:积极倾向高低不同影响个体对情绪声音的注意偏向,并且同时影响个体的信息接收广度。

Objective:The main goal of this study is to examine the attentional bias to emotional sounds in positive-disposed individuals.Methods:There were 33 high positive-disposed participants and 27 low positive-disposed participants hearing positively,neutrally and negatively valence sounds in the present research with the audit.ory adaption of cue-target paradigm.Results:The eliminated effect of IOR was significant when high positive-disposed participants heard positive and negative emotional sounds.What's more,under invalid cue condition,the reaction time to target sounds following positive sounds was significantly longer than that following neutral sounds(P<0.001).And it was the same for negative sounds(P< 0.001).While in low positive-disposed participants,the effect of IOR did not exist only when the cue sounds were positive. Further,under invalid cue condition,only the reaction time to targets following positive cue sounds was longer than that following neutral ones(P<0.05).High positive-disposed individuals had a disengagement bias to both positive and negative sounds,while low positive-disposed people only had a disengagement bias to positive emotional sounds.Conclusion:In a conclusion,the results above may indicate that keeping an eye on positive things may be related to one's positivity.And attention may be a useful tool to regulate emotion.
