Sensory-perceptual abnormalities in autism: a case for more research?

The authors read every paper they could find on unusual sight, sound, touch, and body senses in autism. They wrote a story-style review, not a new experiment. Their goal was to see if the evidence was strong enough to guide teachers and therapists.

They found most studies were small, used different tools, and skipped clear definitions. The team said, 'We need better research before we build treatments.'

Sensory quirks are common in autism, but the proof is weak. Bright lights, humming rooms, or scratchy tags really bother some kids. Yet past work mixed up autism with other issues and used shaky tests.

The review warns against acting on shaky data. It asks future scientists to use tight methods and clear measures.

Later work answered the call. Germani et al. (2014) tracked babies and showed that kids later diagnosed with autism already had sound and registration problems at age two. Rojahn et al. (2012) used brain scans and found dampened touch responses in autistic boys, tying parent reports to real neural data.

Tarantino et al. (2026) goes further and replaces the old view. Their signal-detection model says the issue is poor noise filtering, not simple over-reaction. This 2026 paper supersedes the 1997 plea by giving researchers a concrete blueprint.

MacFarland et al. (2025) keeps the rigor going. They removed ADHD influence and still found sensory sensitivity predicts autism traits, proving the feature is core, not a side note.

You now have solid proof that sensory signs show up early and link to brain data. Use standard tools like the Infant/Toddler Sensory Profile during intake. Seat kids away from vents or bright windows to cut nasal-field loss shown by Bolte et al. (2013). Most of all, demand clear sensory goals in behavior plans instead of vague 'sensory breaks.' The field has moved past guesswork—your assessments should too.
