Beyond pragmatics: morphosyntactic development in autism.
Verbal young learners with autism still mess up basic grammar endings—check syntax, not just pragmatics.
01Research in Context
What this study did
The team compared young learners with autism to kids matched on age and IQ. All children could talk in sentences.
They looked at grammar markers like past tense -ed and plural -s. They also counted jargon and long, off-topic monologues.
Each child told a wordless picture story and answered questions. Transcripts were scored blind to diagnosis.
What they found
Autistic kids used fewer correct grammar endings. They also wandered into long, hard-to-follow monologues twice as often.
Even with similar vocabulary size, the autism group showed clear syntax gaps. Pragmatics alone could not explain the trouble.
How this fits with other research
Baker et al. (2010) saw language growth flatten in preschool autism. Inge-Marie et al. now show the flat curve shows up as real grammar holes by age five.
Bigham et al. (2013) found autistic preschoolers follow gaze in an odd, not just delayed, way. The same pattern appears here: grammar is not just late—it is atypical.
Ellawadi et al. (2017) saw shaky category knowledge in young learners with autism. Both studies point to unstable rule use, whether sorting pictures or building sentences.
Why it matters
If you test only pragmatics you will miss grammar gaps that block classroom learning. Add a quick morphosyntax probe—like having the child retell a story and counting missing -ed or -s. When these endings are wrong, weave grammar goals into the intervention plan even if the child talks a lot.

03Original abstract
Language acquisition research in autism has traditionally focused on high-level pragmatic deficits. Few studies have examined grammatical abilities in autism, with mixed findings. The present study addresses this gap in the literature by providing a detailed investigation of syntactic and higher-level discourse abilities in verbal children with autism, age 5 years. Findings indicate clear language difficulties that go beyond what would be expected based on developmental level; specifically, syntactic delays, impairments in discourse management and increased production of non-meaningful words (jargon). The present study indicates a highly specific pattern of language impairments, and importantly, syntactic delays, in a group of children with autism carefully matched on lexical level and non-verbal mental age with children with developmental delays and typical development.
