Definition
Sensory processing refers to how the nervous system receives, interprets, and responds to sensory input from the eight sensory systems: sight, sound, touch, smell, taste, proprioception, vestibular, and interoception.
Why It Matters
Differences in sensory processing are part of the diagnostic criteria for autism: the DSM-5 criteria, as reproduced by the CDC, include hyper- or hyporeactivity to sensory input. Understanding a person's sensory profile is essential to creating environments where they can function, learn, and thrive.
Common Misconception
Sensory differences are not preferences. An autistic person who cannot tolerate a certain texture is not being picky. The experience is neurological, not volitional.
