Non-word repetition in young school-age children with language impairment and/or neuropsychiatric disorder.
A five-minute non-word repetition test sorts children with combined language and neuropsychiatric disorders into the highest-need group.
01Research in Context
What this study did
Carmela’s team gave a five-minute non-word repetition test to 6- to young learners.
Kids had language impairment (LI), a neuropsychiatric disorder (NPD), or both.
They counted how many made-up words each child copied correctly.
What they found
Children with both LI and NPD scored lowest.
Single-diagnosis groups landed in the middle.
Typical peers scored highest.
The quick test cleanly ranked severity across the three clinical groups.
How this fits with other research
Michel et al. (2024) later showed bilingual preschoolers with DLD struggle most with attention, not memory.
Carmela’s memory-based test still flags severity, but Lisa reminds us to also watch attention in bilingual cases.
Saban-Bezalel (2025) used language-age instead of birth-age when setting pragmatic goals for toddlers with developmental delay.
The same rule applies here: interpret a low NWR score against the child’s language age, not their grade age.
Tsao et al. (2003) found autistic kids skip under-extension errors.
Carmela’s tool can spot the added language hit in kids who already carry autism or other NPD labels.
Why it matters
You can run the NWR screener while waiting for the full evaluation.
A low score signals the child needs the most language-heavy slot on your caseload.
Pair the result with attention and play checks from newer studies to build a full profile.

03Original abstract
We wanted to test the hypothesis that neuropsychiatric disorder (NPD) with language impairment (LI) is a more severe variant of NPD than NPD without LI, and that this variant can be easily picked up by a non-word repetition (NWR) task. We therefore tested 56 (mean 7.6, range 6.1-9.5 years) children divided into three subgroups: one with LI only (n=8), one with NPD only (n=16) and one with a combination of LI and NPD (n=32). We used a Swedish NWR test, a real word repetition test, the Verbal Comprehension and Freedom from Distractibility factor of the WISC-III. All three subgroups had difficulties with NWR and real word repetition compared to the norm, but the within-subgroup variations were considerable. The subgroup with NPD only performed best on both NWR and real word repetitions, but remarkably poorly given that they had never been noted for having language problems. NPD with LI consistently had the lowest scores. Of the three subgroups, only NPD with LI scored lower than the normal range on Verbal Comprehension and Freedom from Distractibility. Significant correlations were found between NWR on the one hand, and Freedom from Distractibility and Verbal Comprehension, on the other, indicating that poor results on a NWR test is probably not a "clean" measure of speech and language impairment, but also taps into other neuropsychological constructs, including executive dysfunction. In conclusion, the study confirmed the hypothesis that NPD with LI constitutes a more severe variant of NPD, and that this variant can easily be picked up by a quick and easy NWR screening test.
