Definition
Interoception is the internal sense that tells us what is happening inside the body: hunger, thirst, needing the toilet, heart rate, breath, body temperature, emotion. The "eighth sense" alongside the seven external senses, interoceptive differences are common in autism and ADHD and have implications across feeding, toileting, emotional regulation, and self-care.
In context for parents
Key checkpoints
- The internal sense that tells us what is happening inside the body: hunger, thirst, needing the toilet, heart rate, breath, body temperature, emotion.
- The "eighth sense" alongside the seven external senses.
- Interoceptive differences are common in autism and ADHD, affects feeding, toileting, emotional regulation, and self-care.
- The Mahler interoception framework (Kelly Mahler, OT, 2017) is the most-used UK clinical model.
- Section F can specify scheduled toileting / hydration support, OT-led Interoception Curriculum sessions, and no consequences for accidents until awareness programme delivered.
Interoception is the sensory channel from the body's internal organs and tissues to the brain. The signals (full bladder, low blood sugar, racing heart, dry mouth, rising body temperature) are typically integrated below conscious awareness in a continuous loop that produces both physical regulation and the felt sense of emotion. The interoceptive cortex (Anterior Insular Cortex, AIC) integrates these signals.
In autistic and ADHD profiles, interoception is frequently atypical: either reduced ("hypo-interoception", the child who genuinely does not feel the full bladder until urgent, who does not register hunger until shaky, who does not feel cold until shivering) or heightened ("hyper-interoception", the child who is overwhelmed by their heartbeat, who feels each breath, who finds the sense of being hot or cold intensely uncomfortable). The Mahler interoception framework (Kelly Mahler, OT, 2017) is the most-used UK clinical model.
In a Reception or Year 1 classroom, interoception difficulty looks like the child still in pull-ups at age 5 not because of motor delay but because they cannot reliably detect bladder fullness. The child who refuses to eat until lunchtime and then cannot eat at all because hunger signals never reached registration. The child whose anger appears to come from nowhere because the underlying physical sensations (heat, tension, racing heart) were not consciously perceived until the moment of explosion.
What helps:
- Direct teaching of interoceptive awareness (Mahler's Interoception Curriculum, used by UK paediatric OTs and increasingly in schools).
- Scheduled toileting, drinking, and eating (not waiting for signals that may not reliably arrive).
- Body-mapping work (helping the child notice and label specific sensations).
- External cues (visual reminders to check in with the body).
- Reduced shame around developmental areas like toileting that may persist past typical age expectations.
In an EHCP, interoception-aware provision can be specified in Section F: "scheduled toileting and hydration support, no consequences for accidents until the interoceptive awareness programme has been delivered, OT-led Interoception Curriculum sessions".
Related terms
The terms parents most often see alongside Interoception.
Sensory Processing Disorder(SPD)
Difficulty taking in, organising, and responding to everyday sensory information (touch, sound, movement, taste, smell, sight, balance, and body awareness) in a way that supports daily life.
Autism(ASC)
A lifelong neurodevelopmental condition that shapes how a person communicates, processes sensory information, and experiences the social world. Autism is a difference, not an illness.
Emotional Regulation
The ability to recognise and manage emotional responses to meet goals and demands. Many neurodivergent children need explicit teaching and ongoing co-regulation to develop these skills.
Avoidant/Restrictive Food Intake Disorder(ARFID)
A feeding and eating disorder where a child restricts what or how much they eat due to sensory sensitivity, fear of choking, or lack of interest, rather than body image.
Where parents ask about this
Parents usually find this page after a school has shamed a child for accidents, or when feeding / emotional regulation problems point to an interoceptive picture. Searches include "interoception autism", "Kelly Mahler interoception curriculum", and "interoception EHCP". A Beaakon paediatric OT with interoception training can carry out an assessment, deliver or supervise the Interoception Curriculum, and write Section F-grade wording that protects the child from inappropriate consequences for interoceptive differences.
