AI Article Synopsis
- Interoceptive information is essential for forming cognitive body representations (BR) that influence how we perceive and interact with our bodies, categorized into action-oriented (like body schema) and non-action-oriented (like a visuo-spatial body map).
- A study with 239 healthy participants of various age groups found that children and older adults performed worse than young and middle-aged adults on tasks related to both types of BR.
- The research indicated an inverted U-shaped trend in the development of BR, suggesting that higher interoceptive sensibility in both children and older adults might negatively impact their ability to mentally represent their body states.
Article Abstract
Background: Interoceptive information plays a pivotal role in building higher-order cognitive body representations (BR) that neuropsychological and neuroimaging evidence classifies as action-oriented (i.e., body schema) or non-action-oriented (i.e., visuo-spatial body map). This study aimed to explore the development of BR, considering the association with the interoceptive sensibility throughout the lifespan.
Methods: Two hundred thirty-nine healthy participants divided into five age groups (7 to 8 years; 9 to 10 years; 18 to 40 years; 41 to 60 years; over 60 years) completed a self-report measure of interoceptive sensibility (the Self-Awareness Questionnaire; SAQ) and were given tasks assessing the two BR (action-oriented: hand laterality task; non-action-oriented: frontal body evocation task).
Results: Both children (7-8 and 9-10 years) and older adults (over 60 years) performed worse than young (18-40 years) and middle-aged adults (41-60 years) in action- and non-action-oriented BR tasks. Moderation analyses showed that the SAQ score significantly moderated the relationship between age and action-oriented BR.
Conclusions: The current results are consistent with inverted U-shaped developmental curves for action- and non-action-oriented BR. As an innovative aspect, the ability to mentally represent one's own body parts in diverse states could be negatively affected by higher interoceptive sensibility levels in childhood and late adulthood.

Influence of interoception and body movement on the rubber hand illusion.

Rubber hand illusion (RHI) refers to the illusory sense of body ownership of a fake hand, which is induced by synchronous visuotactile stimulation to the real and fake hands. A negative correlation was reported between the cardiac interoception and the strength of RHI, but the subsequent studies have been unsuccessful in replicating it. On the other hand, voluntary action is suggested to link interoception and the sense of body ownership in different situations.

Neuroscientists in decision science have advanced an affect-integration-motivation (AIM) framework, demonstrating that neural activity associated with positive affect or value integration can predict individual and aggregate choice. Given that individuals with higher interoceptive sensibility (IS) have tendency to engage their bodily sensations and thus exhibit a more coherent pattern between their neural, affective, and behavioral measures, we investigated how IS may interact with the affective/integrative components for predicting individual and aggregate choice. Thus, we 1) explored neural underpinnings of individual choice, affective ratings, aggregate outcomes, 2) examined how the above-mentioned measures predict individual and aggregate choices on mobile games, and 3) tested the moderation effect of IS by comparing the differences in how these measures perform in prediction models between subgroups of IS.
