Expressive and Receptive Language in Russian Primary-School-Aged Children with Autism Spectrum Disorder.
Expressive-receptive gaps in autism shift with test type and IQ, so assess both skills with matched tasks.
01Research in Context
What this study did
Vardan et al. (2021) looked at Russian school-age kids with autism. They gave tests for talking and understanding words.
Scores were checked against non-verbal IQ and test difficulty. The goal was to see if expressive language is always stronger than receptive.
What they found
Some kids talked better than they understood. Others showed the reverse. The gap changed with each test and with IQ.
No single 'expressive > receptive' rule held for the whole group.
How this fits with other research
Toth et al. (2007) saw receptive lags in toddler siblings who do NOT have autism. The clash looks odd, but the siblings were younger and not diagnosed, so receptive dips can appear without autism.
Qi et al. (2025) review shows autistic kids rarely use tone to predict words. Vardan’s variable scores line up: if prediction is weak, test format will matter more.
Xie et al. (2025) found preschoolers with autism can predict nouns from verbs, just a bit slower. Vardan extends this up the age ladder, showing the same child-by-child pattern in older kids.
Why it matters
Do not assume a child’s talking skill mirrors their understanding. Pick tests that match the child’s IQ and language level. If comprehension looks poor, try a simpler task before writing goals. Always test both sides, then teach the weaker one with materials that fit the child, not the label.

03Original abstract
BACKGROUND: Abnormal language development in both expressive and receptive domains occurs in most children with Autism Spectrum Disorder (ASD), although the language deficit is not a core symptom of ASD. However, previous studies disagree on the difference in the degree of impairment between expressive and receptive language in ASD. Existing research has concentrated on vocabulary and 'global expressive and receptive language', often using parental reports for language assessment. Moreover, most of these studies have focused on toddlers and preschoolers with ASD, whereas data from school-aged children with ASD are very limited. At the same time, the age of children might account for the inconsistencies across publications on expressive-receptive language difference in children with ASD. AIMS: The goal of the study was to directly compare the expressive and receptive language abilities of Russian primary-school-aged children with ASD (7-11 years old) at the levels of vocabulary, morphosyntax, and discourse. METHODS: 82 children with ASD participated in language testing. We used tests from the Russian Child Language Assessment Battery in order to assess vocabulary, morphosyntax, and discourse in expressive and receptive domains. RESULTS: Our results revealed different expressive and receptive patterns, depending on the linguistic level and tests complexity. Importantly, we showed that children's non-verbal IQ partly accounted for the difference between production and comprehension abilities. CONCLUSIONS: The expressive-better-than-receptive pattern in language has been considered by some authors as the unique hallmark of ASD. However, several studies, including our own, show that this is not a universal characteristic of ASD. We also revealed that expressive and receptive language patterns differed depending on the linguistic level, children's non-verbal IQ, and assessment tools.
