Vocabulary and grammar acquisition in Turkish as assessed by the Turkish communicative development inventory

A comparison of typically developing and language delayed children

| Anadolu University, Turkey
| SLP, Dina Center for Speech and Language Disorders, Mersin, Turkey
This study reports results from the recently developed Turkish Communicative Development Inventory (CDI-TR), a parental report measure to assess the vocabulary of children aged 16–36 months. In the study, 60 typically developing (TD) children between 24–36 months and 35 language-delayed (LD) monolingual Turkish-speaking children between 30–48 months were compared with regard to the size of expressive vocabulary, maximum length of utterance (M3L), and sentence complexity. The LD group lagged substantially behind the TD group for vocabulary size as measured in the number of nouns and verbs. The LD group also lagged behind the TD children for mean maximum length of utterance, for all 5 verb and 8 noun inflections and for most of the nine complex sentence structures queried.
Keywords: CDI-TR, typically developing, language-delayed, children, expressive vocabulary, grammar
