Interoception is the process of sensing internal bodily signals, with individual differences influencing emotional responses such as anxiety.
Most studies focus on heart-related signals, revealing a distinction between accuracy in detecting cardiac versus respiratory signals, yet a positive correlation in awareness of one's interoceptive abilities across both types.
The research indicates that respiratory accuracy is linked to higher anxiety levels, while greater awareness of heart signals may reduce anxiety, suggesting different sensory modalities influence emotional and cognitive experiences.
