To better help young school-age children with DLD, we should focus on complex language structures 

The big picture

Traditional language therapy targets language structures, like sentences, in a developmental sequence, starting with simple structures the child isn’t using. But targeting complex structures may be more efficient and functional for school-age children with developmental language disorder (DLD).

Why it matters

Focusing on complex language structures may help students with DLD improve targeted and/or simpler, related language structure skills more efficiently. We’ve seen similar outcomes with speech therapy for children with unclear speech (see below).

Practical example

Using simple picture stories, focus on complex auxiliary “is/are” questions, like this: 

  • Adult: I wonder if the mice are cleaning the kitchen? Ask the puppet! 
  • Child: Are the mice cleaning the kitchen? 
  • Adult: Everyone needs to clean. I wonder if the dog is cleaning? Ask if the dog is cleaning.
  • Child: Is the dog cleaning?

  • This work may help some school-age children with DLD learn both the complex target and/or simpler, related targets at the same time, e.g. The mice are cleaning the kitchen. (Subject-Verb-Object), The dog is sad. (Subject-Verb-Complement).
