Research shows that sensory processing differences are common in autism, with some individuals experiencing hypersensitivity (over-responsiveness) or hyposensitivity (under-responsiveness) to stimuli. Sensory Integration Therapy (SIT) has been studied, but evidence on its effectiveness is mixed. Some studies suggest it may help with sensory challenges, while others call for more rigorous research (National Autistic Society, Autism Research Institute).

The Autism CRC highlights that sensory-based interventions should be personalized, as responses vary widely among autistic individuals. Occupational therapy with a sensory focus can sometimes improve daily functioning (Autism CRC, 2023).
