THE INTERRELATION OF CHILD DIRECTED SPEECH AND CHILD SPEECH IN ACQUISITION OF PERSONAL DEIXIS (BASED ON THE ENGLISH LANGUAGE)
The article deals with the interrelation of child directed speech, child speech and the language system in the development of personal deixis, i.e. the acquisition of the elements of the language concerning their function of indicating a person as a participant in a communication act - personal and possessive pronouns and finite verb forms. We can not deal with the aforementioned elements without taking into consideration structural peculiarities of the language. It has been observed that children, acquiring English as a first language, begin to use the dyad “I-you” significantly earlier, than those acquiring Russian. According to our hypothesis, this may be not only because English is a non-prodrop language with obligatory possessives, but also because of its structural features: strict word order where the place of the subject is evident, what contributes to the earlier acquisition of personal pronouns by children. Considering mutual impact of child speech and parental input we define the bond between the structure of parental utterances in child-directed speech and the acquisition of personal pronouns by the child. This hypothesis has been proved as we have found a correlation between the increase of the share of general and special questions in the parental speech and the increase of the quantity of pronouns “I” and “you” in the child speech.
