Interoception
Interoception is how the nervous system senses and interprets signals from inside the body, such as hunger, heartbeat or temperature.
Break the term down
Interoception intero – ception
- intero
- inside or internal
- ception
- sensing or perceiving
Whole meaning: Interoception is how the nervous system senses and interprets signals from inside the body, such as hunger, heartbeat or temperature.
More precise description
Interoception concerns sensing, interpreting and relating to signals from inside the body; it includes multiple measurable dimensions, and current autism research does not support a simple claim that all autistic people have globally reduced interoception.
At a glance
This page covers
- Internal bodily signals such as heartbeat, breathing, hunger, temperature and other physiological states.
- Interoceptive accuracy, sensibility and awareness as distinguishable measurement dimensions.
- Variation across tasks, ages, neurotypes and contexts.
It does not mean
- Equating interoception with one heartbeat task.
- Assuming an autism diagnosis implies poor interoception.
- Using interoceptive difficulty as a standalone diagnosis.

What remains uncertain
How do different interoception measures map onto everyday bodily awareness across ages, neurotypes and co-occurring conditions?
Laboratory accuracy, self-report and everyday experience may measure different aspects of interoception.
What could reduce this uncertainty?
- Standardised multimethod studies with measurement-invariance testing.
- Longitudinal work connecting laboratory measures to functional everyday outcomes.
Different perspectives
Systematic-review evidence
Interoception should be treated as multidimensional and heterogeneous; contradictory findings are evidence against a one-size-fits-all deficit story.
