Down Syndrome is the most common developmental disorder characterized by mild to moderate intellectual disability. Several studies have reported poor language and prosodic skills, phonological problems due to their deficits caused by intellectual disabilities. This research aims to study over time the expressive use of language in 10 children with Down Syndrome and in 10 children with typical development matched on their chronological age and nonverbal intelligence. We used t-tests analyses and the results showed statistically significant development of the oral vocabulary skills in the children with typical development, but not in the children with Down Syndrome, with the typically developing children showing faster and better development in the oral vocabulary skills than the children with Down Syndrome.
