Study on first language acquisition by Spanish children about grammatical categories

This study investigates how Spanish children acquire their first language based on the longitudinal studies realized in 90 years. The utterances of María in López Ornat et al.(1994) and Magín in Aguirre(1995) show a determinate sequence of grammatical categories in their language acquisition. First of all, in terms of Verbal Phrases, Spanish children acquire infinitive verb forms, imperatives and present tense forms in first and third person at VP level. And then they can distinguish all present verb forms in agreement with subject and acquire past tenses like pretérito perfecto, pretérito indefinido and pretérito imperfecto gradually at IP level. Finally they acquire Wh-questions and subordinate clauses at CP level. In terms of Noun Phrases, they show adquisition of DP at early stages and later PP. In summary, they start precategorial stage and pass to lexical stage and finally to functional stage culminating their first language grammar. The result of this investigation can provide possibility of posterior contrastive studies with other first language acquisition process as well as with second language acquisition process.
