Interoceptive sensitivity is an essential component of recent models of "the self." Increased focus on the self (e.g., self-observation in a mirror) can enhance aspects of self-processing. We examined whether self-observation also enhances interoceptive sensitivity. Participants performed a heartbeat detection task while looking at their own face in a mirror or at a black screen. There was significant improvement in interoceptive sensitivity in the mirror condition for those participants with lower interoceptive sensitivity at baseline. This effect was independent of the order of conditions, gender, age, body mass index, habitual exercise, and changes in heart rate. Our results suggest that self-observation may represent a viable way of manipulating individuals' interoceptive sensitivity, in order to directly test causal relations between interoceptive sensitivity and exteroceptive self-processing.
内感受敏感性是最近“自我”模型的一个重要组成部分。更多地关注自我（例如，在镜子中观察自己）可以增强自我加工的各个方面。我们研究了自我观察是否也会增强内感受敏感性。参与者在观察镜子中的自己的脸或黑色屏幕时执行心跳检测任务。对于那些在基线时内感受敏感性较低的参与者，在镜子条件下，内感受敏感性有显著提高。这种效应独立于条件的顺序、性别、年龄、体重指数、习惯性运动以及心率的变化。我们的结果表明，自我观察可能代表了一种可行的操纵个体内感受敏感性的方法，以便直接测试内感受敏感性和外感受自我加工之间的因果关系。
