Sensory and attention abnormalities in autistic spectrum disorders.

Parents filled out an expanded Sensory Profile about their autistic kids.

The team looked for clusters of sensory and attention scores.

They wanted to see if a single over-arousal pattern showed up.

Forty-three percent of the children fit one tight cluster.

These kids were both over-reactive to sounds, touch, lights and over-focused in attention.

The pattern supports the idea that too much sensory input can lock attention in place.

Farley et al. (2022) repeated the cluster trick in 919 youth and found the same over-focused group, so the pattern is real and stable.

Green et al. (2016) later counted sensory issues in DSM-5 language and showed the problem is even bigger—92% of autistic kids have some sensory quirks—extending the 2006 picture.

Delgado-Lobete et al. (2020) looked at kids with DCD or ADHD, not autism, and saw the opposite pattern: low registration instead of over-responsivity. The studies seem to clash, but they tested different diagnoses, so both can be true.

Diemer et al. (2023) added hidden integration deficits like poor balance and praxis, reminding us that sensory troubles go beyond the classic profile.

If you see a child who startles at every sound and then can’t shift gaze, screen for the over-focused cluster.

Use any caregiver Sensory Profile form; you don’t need extra gear.

Pair your results with emotional and RRB measures—sensory over-arousal often rides along with rigid behavior.

Plan breaks, reduce visual clutter, and give warning cues before changes.
