Nineteen subjects high in social anxiety and 20 subjects low in social anxiety were asked to give a 5-min speech in front of three audience members. Audience members were trained to provide indicators of positive evaluation (e.g., smiles) and negative evaluation (e.g. frowns) at irregular intervals during the speech. Subjects were instructed to indicate, by depressing one of two buttons, when they detected either positive or negative behaviours. Results indicated that subjects high in social anxiety were both more accurate at, and had a more liberal criterion for, detecting negative audience behaviours while subjects low in social anxiety were more accurate at detecting positive audience behaviours.
19名社交焦虑程度高的受试者和20名社交焦虑程度低的受试者被要求在三名观众面前进行5分钟的演讲。观众接受培训，要在演讲过程中间歇性地给出积极评价（如微笑）和消极评价（如皱眉）的示意。受试者被要求通过按下两个按钮中的一个，来表明他们何时察觉到了积极或消极行为。结果表明，社交焦虑程度高的受试者在察觉观众的消极行为时，既更准确，标准也更宽松；而社交焦虑程度低的受试者在察觉观众的积极行为时更准确。
