Sensory Processing in Low-Functioning Adults with Autism Spectrum Disorder: Distinct Sensory Profiles and Their Relationships with Behavioral Dysfunction.

Gonthier et al. (2016) looked at sensory issues in low-functioning adults with autism. They wanted to see if different sensory patterns link to different behavior problems.

The team used tests and caregiver forms to map each adult's sensory world. Then they grouped the adults by shared sensory traits.

Four clear sensory profiles popped out. One group was over-sensitive to sounds and touch. Another group hardly reacted to anything. The other two groups mixed seeking and avoiding in unique ways.

Each profile came with its own set of tough behaviors. Knowing the profile let the team guess which behaviors would show up later.

Ben-Sasson et al. (2019) pooled many studies and found the same three basic patterns: over-react, under-react, and seek. Corentin's four profiles fit inside that bigger picture, giving finer detail for low-functioning adults.

Romero (2017) showed that sensory quirks track with autism traits in both neurotypical and autistic adults. Corentin's work narrows the lens to the most disabled end of that spectrum.

Kargas et al. (2015) saw that better auditory skills went with fewer repetitive behaviors in higher-functioning adults. Corentin flips the view: in low-functioning adults, the whole sensory map predicts behavior, not just hearing.

You can run a short sensory profile in your intake. Pick the closest match to Corentin's four types and you get a head start on which behaviors to watch. If your client is the over-sensitive type, plan for escape and aggression around loud rooms. If they are the under-sensitive type, watch for self-injury when stimuli are too low. Build your behavior plan around the sensory driver, not just the behavior you see.
