高焦虑个体对威胁性词语的注意偏向及习惯化
  • 摘要

    目的:探讨随刺激呈现次数的增加,高焦虑个体对威胁性刺激注意偏向的变化.方法:被试为大一新生,依据状态-特质焦虑问卷得分,随机选择了得分最高的25%部分中的24人作为高焦虑组,得分最低的25%部分中的23人作为低焦虑组.实验采用点探测视觉搜索任务,以威胁性词语为刺激材料,刺激呈现8次,分析刺激每次呈现时高低焦虑组被试对威胁性词语的注意偏向.结果:当刺激首次呈现时只有高焦虑组被试的注意偏向值与0相之间差异有显著性(t=2.34,P<0.05).方差分析显示在刺激呈现的前三次,随着刺激呈现次数的增加,只有高焦虑组被试的注意偏向值发生了显著的变化(F=5.44,P<0.01. 注意偏向值分别为:13.1±27.3,2.5±27.0,-10.0±27.9),对刺激呈现的后五次高低焦虑组个体的注意偏向值变化均不显著.结论:随着词语刺激呈现次数的增加,高焦虑被试对威胁性词语的注意偏向表现出习惯化倾向.
