TAILIEUCHUNG - Báo cáo khoa học: "SIMULATING CHILDREN'S NULL SUBJECTS: A NEARLY LANGUAGE GENERATION MODEL"

This paper reports work in progress on a sentence generation model which attempts to emulate certain language output patterns of children between the ages of one and one-half and three years. In particular, the model addresses the issue of why missing or phonetically "null" subjects appear as often as they do in the speech of young Englishspeaking children. It will also be used to examine why other patterns of output appear in the speech of children learning languages such as Italian and Chinese. Initial findings are that an output generator successfully approximates the null-subject output patterns found in English-speaking children. | SIMULATING CHILDREN S NULL SUBJECTS AN EARLY LANGUAGE GENERATION MODEL Carole T. Boster Department of Linguistics Box U-145 University of Connecticut Storrs CT 06269-1145 USA tenny@ Abstract This paper reports work in progress on a sentence generation model which attempts to emulate certain language output patterns of children between the ages of one and one-half and three years. In particular the model addresses the issue of why missing or phonetically null subjects appear as often as they do in the speech of young Englishspeaking children. It will also be used to examine why other patterns of output appear in the speech of children learning languages such as Italian and Chinese. Initial findings are that an output generator successfully approximates the null-subject output patterns found in English-speaking children by using a processing overload metric alone however reference to several parameters related to discourse orientation and agreement morphology is necessary in order to account for the differing patterns of null arguments appearing cross-linguistically. Based on these findings it is argued that the null-subject phenomenon is due to the combined effects of limited processing capacity and early accurate parameter setting. 1 TSE PROBLEM It is well known among researchers in language acquisition that young children just beginning to speak English frequently omit subjects in linguistic contexts where subjects are considered mandatory in the adult language. Other major structural components such as verbs and direct objects are also omitted occasionally however the frequency at which children omit mandatory object NPs tends to be much lower than the rate at which they omit subjects. For example p. Bloom s 1990 analysis of early speech transcripts of Adam Eve and Sarah Brown 1973 from the CHILDES database MacWhinney and Snow 1985 indicates that these children omitted subjects from obligatory contexts 55 of the time on average whereas obligatory
