This is a quarterly report of a project involving the analysis of the language of four Puerto Rican children living in the Boston area who are learning Spanish as a first language. The children, all male, ranged in age from 17 months to 37 months during the period of study. All had some contact with English. The data were transcriptions of spontaneous conversation between the researcher and each child. The analysis was of: (1) the order of acquisition of Spanish verb forms, and (2) the influence on the acquisition of the child's repetitions of verbs spoken previously in conversation by the adult. Errors in the children's verb systems were similar. For all, the form used in more inappropriate contexts was the third person singular. It seems that this is the basic form. Two assumptions were made about the nature of repetitions: (1) the child determines what s/he will repeat; and (2) the adult's model is not appropriate or inappropriate by itself; rather its appropriateness depends on the subject the child uses in his/her subsequent utterance, which is determined by the child. The same questions will be addressed in a subsequent study in Puerto Rico. (AMH)
