The Approach-Avoidance Task (AAT) was employed to indirectly investigate avoidance reactions to stimuli of potential social threat. Forty-three highly socially anxious individuals (HSAs) and 43 non-anxious controls (NACs) reacted to pictures of emotional facial expressions (angry, neutral, or smiling) or to control pictures (puzzles) by pulling a joystick towards themselves (approach) versus pushing it away from themselves (avoidance). HSAs showed stronger avoidance tendencies than NACs for smiling as well as angry faces, whereas no group differences were found for neutral faces and puzzles. In contrast, valence ratings of the emotional facial expressions did not differ between groups. A critical discrepancy between direct and indirect measures was observed for smiling faces: HSAs evaluated them positively, but reacted to them with avoidance.
采用趋近-回避任务(AAT)间接研究对潜在社会威胁刺激的回避反应。43名高度社交焦虑个体(HSA)和43名非焦虑对照者(NAC)通过将操纵杆拉向自己(趋近)或推离自己(回避),对情绪性面部表情图片(愤怒、中性或微笑)或对照图片(拼图)做出反应。对于微笑和愤怒的面孔,HSA比NAC表现出更强的回避倾向,而对于中性面孔和拼图则未发现组间差异。相比之下,情绪性面部表情的效价评分在两组之间没有差异。对于微笑面孔,直接测量和间接测量之间存在关键差异:HSA对它们给予积极评价,但却以回避反应。
