According to current cognitive models of social phobia, individuals with social anxiety create a distorted image of themselves in social situations, relying, at least partially, on interoceptive cues. We investigated differences in heartbeat perception as a proxy of interoception in 48 individuals high and low in social anxiety at baseline and while anticipating a public speech. Results revealed lower error scores for high fearful participants both at baseline and during speech anticipation. Speech anticipation improved heartbeat perception in both groups only marginally. Eight of nine accurate perceivers as determined using a criterion of maximum difference between actual and counted beats were high socially anxious. Higher interoceptive accuracy might increase the risk of misinterpreting physical symptoms as visible signs of anxiety which then trigger negative evaluation by others. Treatment should take into account that in socially anxious individuals perceived physical arousal is likely to be accurate rather than false alarm.
根据当前社交恐惧症的认知模型，社交焦虑个体在社交情境中会对自己产生扭曲的印象，至少部分依赖于内感受线索。我们研究了 48 名社交焦虑程度高和低的个体在基线时和预期公开演讲时的心跳感知差异，作为内感受的替代指标。结果显示，高恐惧组在基线和演讲前的错误评分较低。只有两组参与者在演讲前的心跳感知略有改善。使用实际心跳和计数心跳之间最大差值的标准，确定了 9 名准确感知者中的 8 名是高社交焦虑者。更高的内感受准确性可能会增加将身体症状误解为焦虑可见迹象的风险，从而引发他人的负面评价。治疗应该考虑到，在社交焦虑的个体中，感知到的身体唤醒很可能是准确的，而不是虚假警报。
