Abstract: High-trait-anxiety individuals' attentional bias to threatening stimuli is related to threat intensity. The study aimed to investigate attentional bias of trait-anxiety individuals toward stimuli with different threat intensity. 33 high-trait-anxiety individuals and 31 control-group individuals were selected from 265 university students. The results showed that: 1)high-trait-anxiety individuals in the face of mildly threatening stimuli showed significantly longer response latencies than control-group individuals when points probe the neutral pictures relative to threatening pictures; 2)high-trait-anxiety individuals in the face of highly threatening stimuli showed shorter response latencies when points probe the neutral pictures relative to threatening pictures. The conclusions were that: 1)high-trait-anxiety individuals had attentional bias to mildly threatening stimuli but attentional avoidance to highly threatening stimuli; 2)control-group individuals had attentional bias to highly threatening stimuli but no to mildly threatening stimuli.

Key words: trait-anxiety, dot-probe, attentional bias, attentional avoidance

摘要： 采用点探测实验范式，将图片按照威胁性分为高威胁性和一般威胁性，探讨焦虑程度不同的个体对不同威胁性刺激的注意特点。采用状态-特质焦虑问卷从265个大学生中选取了33名高焦虑被试和31名对照组被试。结果发现：（1）高焦虑组个体对一般威胁性刺激有显著注意偏向，对高威胁性刺激有注意回避趋势；（2）对照组个体对一般威胁性刺激没有表现出注意偏向，对高威胁刺激有注意偏向趋势。结论：（1）即使是一般威胁性图片也能引起高焦虑被试的注意偏向 （2）高威胁性图片才能引起对照组个体产生注意偏向的趋势。
