Thesis title: Input influence on early vocabulary acquisition in french children
Supervisor : Sophie Kern
Summary
Individual, social and linguistic features can explain variability observed in early vocabulary acquisition. One original feature of this work is to combine focus on both quantity and quality of input with an assessment of activity context influence. Indeed influences of quantitative and qualitative aspects of input on early lexicon development are clearly showed in previous study. In addition, other research has described language development and input differences according to activity type. However, most of these studies have restricted their analyses to one or two activity contexts for example free play and book-reading, and linked these activities to input and older development skills such as literacy. Thus, activity context is seldom studied throughout longitudinal corpus data and its relationship to early vocabulary acquisition has never been examined so far.
While taking into account the results of previous studies, the goal of this thesis is to pay specific attention to input inter-individual and intra-individual variability according to contexts and families’ activities to explain children’s developmental trends.
More precisely, in order to shed light on early vocabulary acquisition, we analyze the productions of 10 French monolingual children from first word to beginning of grammar in interaction with their caregivers and close family at the children’s homes.
Another special feature to this work is the ethological approach adopted for the observation and analysis of activity: we have observed all the activities in longitudinal spontaneous data recordings made at the children’s home.
