Predictors of parent-child language during novel task play: a comparison between typically developing children and individuals with Down syndrome.

Johnson-Glenberg et al. (2004) · Journal of intellectual disability research : JIDR 2004
★ The Verdict

Parents of kids with Down syndrome talk in longer sentences than expected but still adjust word choice to the child’s understanding level.

✓ Read this if BCBAs writing parent language coaching goals for young clients with Down syndrome.
✗ Skip if Clinicians only treating adults or clients without developmental delays.

01Research in Context

01

What this study did

The team watched parents and kids play a new toy task together.

Some kids had Down syndrome. Some were typically developing.

They counted every word and sentence parents used.

02

What they found

Parents of kids with Down syndrome used longer sentences than other parents.

But they did not shorten those sentences to match the child’s level.

They did pick easier words when the child’s understanding was low.

03

How this fits with other research

Polišenská et al. (2014) later showed Down syndrome language is delayed yet follows a normal path.

That backs the idea that parents can trust steady, age-paced goals even if MLU looks high.

Roch et al. (2013) found the same kids can learn new words from quick context cues.

Together the papers say: receptive skills are stronger than they seem, so give rich but tuned input.

04

Why it matters

You can relax about parent sentence length. Instead, check the child’s receptive syntax and coach parents to swap hard words for easier ones. Keep sentences natural; just tune the vocabulary.

03Original abstract

Three questions were asked that explored the linguistic fine-tuning hypothesis and how parents might model language: (i) do parents significantly tune to their children's productive language or non-verbal cognition during play? (ii) is the level of the linguistic tuning different in the Down syndrome (DS) population compared to a typically developing (TD)-match group population? and (iii) do the two populations differ in requests for labels and the scaffolding responses to the requests? In an exploratory play condition, parents of children with DS used a mean length of utterance (MLU) significantly higher than the MLU used by the parents of younger TD children who were matched for MLU. Thus, the DS parents have a higher baseline MLU, but the non-significant correlations in the DS group do not support parental MLU tuning. There was evidence, however, for parental tuning to the children's lexicon using a number of different words when the DS children were at lower and average levels of receptive syntax and non-verbal cognition. In addition, DS and TD parents requested labels for novel toys with the same frequency, perhaps indicating that all groups of parents are still probing and building their children's lexicons. This is an important finding because it may help to explain why adolescents and young adults with DS have vocabulary comprehension skills greater than one would predict from measures of their production and non-verbal cognition.
