What is it about?

Children with developmental language disorder (DLD) show important difficulties in the use of verbs. The present study shows how children with DLD comprehend verbal number morphology in an online task (singular morphological markers vs. plural morphological markers), using an eye-tracking method.

Why is it important?

The empirical results suggest that number morphology comprehension in children with DLD could be more typical than what is generally considered to be. A more preserved comprehension of verb morphology raises the possibility of a better prognosis. Additionally, teachers and speech therapists may enable the comprehension of growing complex grammar through the use of verb morphology in simple sentences, along with the support of visual scenes and the gradual addition of more complex structures.


We hope that our research will have an impact in the clinical and educational reality of children with DLD. It is important to keep in mind that a dysfunctional language is closely related to school failure. In this sense, the design of specific psycholinguistic material can be the basis in order to experience a more fluid linguistic, educational and emotional development.
