Recent research has focused on the contribution of interoception - which refers to one’s sense of internal bodily states - in self-relevant processing. Newly self-associated stimuli are processed faster and more accurately than non-self-associated stimuli; this is known as the self-prioritization effect (SPE). Prior studies indicate that the SPE is negatively correlated with interoceptive accuracy, defined as one’s ability to accurately perceive one’s interoception. Another concept that captures individual differences in interoception is interoceptive sensibility (IS), which is the degree to which one is aware of changes in one’s interoception in daily life. However, it remains unclear whether IS and SPE are correlated. Thus, we examined the relationship between IS and SPE in online surveys. In Study 1 (N=100), we used the Body Awareness subscale of the Body Perception Questionnaire to assess IS related to negative emotions. In Study 2 (N=128), we used the Noticing subscale of the Multidimensional Assessment of Interoceptive Awareness to evaluate general IS that is not limited to negative emotions. However, both studies showed no significant correlation between IS and SPE. These results suggest that the degree to which one is aware of changes in interoception induced by changes in internal bodily states is not tied to SPE.
