Abstract :This study was designed to investigate the difference in first words between typically developing children and language impaired children. Data were collected from 228 typically developing children and 21 language-impaired children. The data include questions to caretakers such as the period of the first-words production, the sound of the first-words production, the meaning of the first-words production, and the impression of the parents about their children’s first-words development. The following is the result of the questionnaire: Of the typically developing children, approximately 90% produced their first words by 15 months of age. A majority of the first words consist of “ma-ma” meaning “mother” in Japanese. The second frequently uttered words are “mam-ma” meaning “food” in Japanese. The parents of typically developing children noticed when their children did not produce their first words by 17 to 18 months of age. A majority of the language impaired children did not produce their first words before 17 month years old. In some cases, the production of the first words did not occur until four years old. The content of the first words were the same in most cases for both the typically developing and the language impaired children. However, the language impaired children uttered such words as “o-wa-ri” meaning “finish” in Japanese and “go” in English. These words were not identified in the production of the typically developing children. These results suggest that the first-words production is delayed in the language impaired children, and some of the words produced by the impaired children are different from those produced by the typically developing children.
