Overview
A. Jean Ayres was an occupational therapist and psychologist who developed Sensory Integration Theory in the 1960s and 1970s, changing how therapists understand and treat sensory processing challenges. She researched how the brain organizes sensory information, such as touch, movement, and balance, and how difficulty processing it can affect learning and behavior. Ayres created specialized equipment, including swings and climbing structures, to help children practice organizing sensory information through play. Her research became especially influential in supporting children with autism and learning differences.
Why She Matters
Ayres' work gave occupational therapists a scientific framework for understanding why some children struggle with balance, coordination, or everyday sensations, and it introduced practical tools to help. Sensory integration therapy, built on her research, is now used in schools, clinics, and homes worldwide. Her willingness to ask new questions about the connection between the senses and behavior expanded what occupational therapy could address. For young people interested in occupational therapy, Ayres' story shows how curiosity about the brain can lead to tools that help millions of children thrive.
