Sensory Processing
Sensory processing is defined by Carol Stock Kranowitz in The Out of Sync Child as, “neurological procedure of organizing the information we take in from our bodies and the world around us for use in daily life.”
Parts of sensory processing:
- Reception and detection: sensations received in the PNS and CNS notices them
- Integration: sensory systems connect in the brain
- Modulation: brain’s regulation of sensory input
- Discrimination: tell the difference between sensory stimuli, allows us to perceive quality, similarities, and differences among sensations
- Postural responses and praxis: get into and stay in a stable position, conceptualize a sequenced movement, organize body, and execute the task
The infographic below depicts these parts of the process and the cyclical manner in which they occur.

When any of these parts of the process is disrupted, sensory processing disorder occurs. Kranowitz defines sensory processing disorder as, “the inability to use information received through the senses in order to function smoothly in daily life.” Subtypes and symptoms of the disorder include:
- Sensory modulation problems: (over responsive) avoids touching or being touched, avoids moving or being moved, insecure about balance, rigid and uncoordinated, over excited with too much to look at, covers ears, objects to normal odors, objects to textures and temperatures of foods. (under responsive) unaware of physical feelings, protects self poorly, ignores visual stim, responds slowly to approaching objects, ignores ordinary sounds, unaware of odors, eat food without reaction. (sensory craving) bumps into people, craves spinning and movement, craves squeezes, seeks visual stim, attracted to shiny things, welcomes loud noises, seeks strong odors.
- Sensory discrimination problems: poor body awareness, cannot feel self falling, clumsy, difficulty telling differences in pictures or expressions, differentiating between sounds, cannot distinguish smells
- Sensory-based motor problems: loose/floppy muscle tone, loses balance easily, difficulty using both sides of body at once, no hand preference
- Dyspraxia: difficulty understanding and doing complex/sequenced movements, poor coordination, difficulty with manual tasks and using both eyes together, may drool excessively and trouble articulating speech
Treatment/therapies for sensory processing disorder have proven to be effective in improving sensory processing in children. If you recognize these symptoms in your child or client, a formal diagnosis can be made by a healthcare professional, and several free treatment options may be available through state and community based programs.
