Abstract
This study explored the relationship between interoceptive sensitivity and the experience of public-speaking anxiety. We compared participants with high and low interoceptive sensitivity concerning self-report and behavioral measures of anxiety and concerning physiological variables before, during, and after a public-speaking task. Participants with high interoceptive sensitivity reported significantly less state anxiety before and after performing a public speech as well as less habitual public-speaking anxiety. No significant differences in behavioral or physiological measures were observed. We assume that individuals with high interoceptive sensitivity, to whom physiological signals are more easily accessible, experience less uncertainty during public speaking and can thus adjust their emotional processes more adequately. This finding appears in line with Damasio’s somatic marker hypothesis, which suggests that reasoning, decision-making, and social behavior are optimized by body-related signals in complex situations.
