Inhibition in autism: children with autism have difficulty inhibiting irrelevant distractors but not prepotent responses.

The team gave kids two quick games on a computer. One game asked them to press a button fast, then stop when a red light popped up. The other game showed pictures with extra doodles around the edges; kids had to name only the middle picture.

All kids had autism. Their scores were matched against same-age peers without autism.

Autistic kids stopped their button press just as fast as peers. They did not show a prepotent response problem.

When extra pictures cluttered the screen, autistic kids made more mistakes. They had trouble ignoring the junk. This was the distractor problem.

Sanderson et al. (2013) seems to disagree. They saw no distractor deficit in autism. The key difference: they removed kids with ADHD symptoms. Early et al. (2012) kept them. The clash shows distractor trouble may ride along with attention issues, not autism alone.

Lindor et al. (2019) narrowed it further. Only autistic kids who also had poor motor skills failed the distractor game. Again, the deficit shrinks when you split the group.

Murphy et al. (2014) added brain data. Autistic kids lacked the normal alpha-wave filter that blocks junk input. The brain finding backs the behavioral clutter problem C et al. saw.

You do not need to drill stop-and-wait skills most of the time; autistic learners can already brake. Instead, cut visual noise. Use plain materials, one item per page, and shield work areas from moving posters or busy shelves. If attention still drifts, screen for motor or ADHD features and tailor supports to those, not just the autism label.
