Is grammar spared in autism spectrum disorder? Data from judgments of verb argument structure overgeneralization errors.

The team asked kids to judge silly sentences. Example: “The magician disappeared the rabbit.” The verb disappear can’t take an object, so the sentence sounds off.

Children with autism and typical peers gave thumbs-up or thumbs-down to many such lines. Both groups had similar IQ scores. The goal was to see if the autism group noticed the tiny grammar slips.

Typical kids quickly rejected the wrong sentences. Kids with autism said “sounds okay” more often. The difference was small but clear. Even bright students with autism can miss subtle grammar rules.

Davis et al. (2018) extends this idea to deaf children. They found that deaf kids with autism also show language gaps, but the gaps are bigger and tied to motor planning.

Avraam et al. (2019) seems to disagree. They showed that people with autism follow visual grouping rules just like typical people. The trick is that their task had no competing cues. When the rules are plain and the scene is simple, rule use looks normal.

Hadad et al. (2015) agree with Ravit. They proved that autism learners can integrate visual info when the task tells them exactly when to do it. Together these studies say: rule problems show up only when the cue is soft or the rule is hidden.

Your student may speak in full sentences yet still miss fine grammar points. Do not assume comprehension is intact. During language lessons, highlight the rule plainly. Use color cues, explicit labels, and lots of examples. Check understanding with forced-choice tasks instead of open questions.
