Title of Thesis/~issertation: Author : (signature ) (name ) (date) ABSTRACT , In this descriptive study of the language growth and development of two boys between the ages of 2 and 3 years, the focus is on the mothers1 roles as they provide language input through mother-chi l d dialogue. From data provided by the transcriptions of monthly video- tapes of natural play sessions in each home setting, three aspects of the conversations of the two dyads are considered: to what degree the range of speech strategy and style exhibited by one mother is different from that of the other mother; whether each mother's differences are refl ected in recogn izable ways in the speech performance of her own . child; and, in spite of mother differences, what similarities there are between the two children in speech development at this stage. Unlike the children in many language studies, the subjects ccme from non- professional , non-academic fm i ly backgrounds. An abductive anal yt ical approach is used, the goal' being to throw more I ight on the process of rapid language acquisition that takes place in the child's third year. Work in the field in the 1960's and early 1970's had suggested that the mother's role is one of I1simpl ic ity and redundancyt1, a supposition that i s chal l enged and then reoriented . The study findings are cast in a general linguistic framework uti- I izi ng the descr iptive analytical levels of phonetics, syntax, semantics, and pragmatics. There is a clear presentation and exegesis of the d is- tinction between what are particular and shared l ingui stic developments in the two children. Phonetically, an echo phenomenon is observed to be operat ing, seeming ly a rote rep1 ay mechanism re1atively independent of cogn itive and length restrictions. Salient prosodic qualities of each i i i mother's speech are mirrored in her own chi I dfs perfomance, particularly I as regards rate, elision, and pitch change factors. This repetitive type of speech appears to be we1 l established even in the initial tapes. During the course of the year, developments in the spontaneous speech of the two chi l dren are demonstrated to be simi l ar in that both boys are able to adapt familiar, stereotyped phrase and sentence forms by introducing syntagmatic and paradigmatic variations, a ski1 l that is characterized as an accumulative process. In this second type of speech production, length of utterance and extent of lexical choice increase over time. A third type of language use, in which there are elements of personal construction, makes an appearance occasionally but is little developed by either child. In the course of the analysis, C.S. Peircels general categories (his icon, index, and symbol ,cl assi f ication) are modi f ied to suit the particular form of the data in order to establ ish a d i stinct ion between l anguage that i s ma inl y ostensive and i nformaiive in form and intent and language that is more clear1 y symbol ic and pred ica- tive. The appl ication of this distinction results in a demonstration of re1ationshi p between pragmatic-s i tuationai factors and language develop- ment in the context of mother-chi l d language interplay. Within develop- mental l imitations of an epistemolq ical nature, the mother (adult) role in early child language acquisition is found to be definitive. ACKNOWLEDGEMENTS , First of all recognition must be given to Simon Fraser Universityls unique Special Arrangements Program wh ich makes cross-di sc ipl inary studies such as this one possible. Many thanks are due individual pro- fessors, videotape technicians, and secretaries in various departments (Audio-visual, Education, Linguistics, and Psychology) for their aid at parti cu l ar stages of the project. I am deeply appreciative of the helpfulness and patience extended to me by the members of my interdisciplinary supervisory committee. To- gether, their talents and expertise covered a wide field. Acknowledge- ments go to Dr. Sheila OIConnell, of the Faculty of Education, Dr. Elinor Ames,. of the Department of Psychology, and Dr. E.W. Roberts, of the De- partment of Languages, Literatures, and Lingu i stics. As Senior Supervisor, Dr. Charles Bouton of the Languages, Litera- tures, and Lingu i stics Department acted as mentor and guide in the preparation of the dissertation, a task to which he freely appl ied the considerable breadth and depth of his knowl edge of language acquisition. His enthusiasm for scholarly investigation and unf l agg i ng attent ion to the progress of the work were of great personal encouragement, and his coordination of the supervisory committee enabled a cooperative and har- mon ous spirit to develop. Of prime importance was the contribution of the two mothers and the two children whose conversations formed the data base of the study. Their wi I ing and interested participation made the videotaping sessions feasible. For all concerned it has been a shared academic venture.
