Previous studies have shown that social anxiety was associated with enhanced acquisition of anxiety as measured by subjective ratings in conditioning tasks using faces as the conditioned stimulus and negative evaluation as the unconditioned stimulus. However, a recent study failed to replicate the effect. The current study re-examined the enhanced acquisition effect with a larger sample, explored whether differences in expectancy of negative evaluation was a potential mechanism, and compared the contribution of social anxiety to that of depression on enhanced acquisition. Two hundred and sixty-three unselected participants took part in a differential conditioning task in which three faces each were paired with hostile, neutral, and friendly reaction during acquisition, and all three were paired with neutral reaction during extinction. Results replicated earlier findings that participant social anxiety was associated with enhanced acquisition of anxiety. Socially anxious participants did not show higher expectancy of hostile reaction during acquisition, which suggested the need to consider alternative mechanisms underlying enhanced acquisition. Depression was also associated with enhanced acquisition; however, that association was accounted for by social anxiety. The effect of social anxiety was significant over and above depression, which supported its diagnostic validity.

以前的研究表明，社交焦虑与增强的焦虑感获得相关，这可以通过使用面部表情作为条件刺激和否定评估作为条件刺激来进行条件调节任务中的主观评分来衡量。但是，最近的一项研究未能复制这种效果。当前的研究以更大的样本重新检验了增强的获得性效果，探讨了否定性评估的预期差异是否是一种潜在的机制，并比较了社交焦虑对抑郁对增强获得性的贡献。263名未选出的参与者参加了差异调节任务，其中三张面孔在采集过程中均与敌对，中立和友好反应配对，而三张面孔在灭绝过程中均与中立反应配对。结果重复了先前的发现，即参与者的社交焦虑与焦虑感的增强有关。社交焦虑的参与者对并购过程中的敌对反应没有更高的期望，这表明需要考虑加强并购的其他机制。抑郁也与获得性增强有关；但是，这种交往是由社交焦虑引起的。社交焦虑症对抑郁症的影响超过抑郁症，这支持了其诊断有效性。抑郁也与获得性增强有关；但是，这种交往是由社交焦虑引起的。社交焦虑症对抑郁症的影响超过抑郁症，这支持了其诊断有效性。抑郁也与获得性增强有关；但是，这种交往是由社交焦虑引起的。社交焦虑症对抑郁症的影响超过抑郁症，这支持了其诊断有效性。
