摘要:

目的:探讨高特质焦虑个体对负性情绪信息注意偏向的机制。方法:采用线索-靶子范式检测不同SOA下焦虑组和对照组的表现。结果:实验一发现,焦虑组只有在负性情绪面孔做线索时表现出提示效应,对照组无论是中性面孔还是负性情绪面孔做线索都表现出提示效应;实验二发现,焦虑组在中性面孔做线索时表现出返回抑制效应,在负性情绪面孔做线索时表现出提示效应,对照组无论是中性面孔还是负性情绪面孔做线索都表现出返回抑制效应。结论:高焦虑个体在SOA较短时由于对负性情绪信息的注意易化,对负性情绪面孔线索产生提示效应,在SOA较长时由于对负性情绪信息的注意脱离困难,返回抑制能力受损,仍对负性情绪面孔线索产生提示效应。

Objective: To explore the mechanism on attentional bias to negatively emotional information in high traitanxiety individuals. Methods: Cue-target paradigm with two different stimulus onset asynchrony(SOA) was used to examine different performances between high trait-anxiety group and control group with neutral faces and negatively emotional faces as clues. Results: In Experiment 1 with an SOA less than 200ms, there was a cueing effect in high trait-anxiety group only when negatively emotional faces were used as clues before target stimulus; meanwhile, there was a cueing effect in control group when both neutral faces and negatively emotional faces were used as clues before target stimulus. In Experiment 2 with an SOA more than 200ms, there was an effect of Inhibition of Return in high trait-anxiety group when neutral faces were used as clues, whereas such effect of Inhibition of Return was undermined in high trait-anxiety group when negatively emotional faces were used as clues. On the contrary, there was a cueing effect in high trait-anxiety group when negatively emotional faces were used as clues. There was an effect of Inhibition of Return in control group when both neutral faces and negatively emotional faces were used as clues. Conclusion: The finding of a cueing effect in high trait-anxiety group with negatively emotional faces as clues when SOA was short suggests attentional facilitation towards negatively emotional information in high trait-anxiety individuals., while that of a cueing effect instead of Inhibition of Return in high traitanxiety group with negatively emotional faces as clues when SOA was long suggests their difficulties in attention disengagement from negatively emotional information in high trait-anxiety individuals.
