In this study we are interested in how mothers talk to different children within the same family when one sibling experiences a delay in developing language.

During early childhood children begin to learn how others think, feel, and act.We know conversations between mothers and their children are important for helping children to learn about others. 

Participation will involve a single, one hour visit to the Early Cognitive Development Centre at The University of Queensland, St Lucia.

During this visit, each child will complete a measure of vocabulary understanding and expressive vocabulary knowledge, and a fun play-based social thinking task with toy characters.

Each child will also be asked to engage in a book reading activity with their mother. Mothers and children will be video- and audio-recorded during these tasks.


Families that include the following:

  • One child aged 2.5 – 8 years old diagnosed with Developmental Language Disorder (DLD)
  • One child aged 2.5 – 8 years old who is typically developing
