Abstract While previous research on language development has highlighted the facilitating role of gesture (mainly deictic gesture) in children’s early access to meaning, little is known about the possible facilitating role of prosody and also of co-speech gestures in children’s pragmatic development in the preschool years. Previous work on developmental pragmatics has focused on the acquisition of morphosyntactic and lexical forms, and there is a need to adopt a more integrative multimodal perspective. The overarching aim of this thesis is to experimentally investigate, through a set of cross-sectional studies with preschool children (3- to 5-year-olds), whether prosodic and gestural cues serve as pragmatic precursors in the development of two key pragmatic phenomena, namely knowledge state (i.e., commitment to the status of information) and politeness (e.g., broadly speaking, adjusting one’s language).
The first study uses a forced-choice paradigm to investigate preschool children’s understanding of another speaker’s knowledge state, presented in audio only, video only and audio-visual formats. Results show that overall children perform significantly better in detecting a speaker’s uncertainty when they have gestural cues present, and, importantly, the younger children were significantly better in detecting a speaker’s uncertainty when listening to a speaker’s intonation contour as compared to uncertainty expressed through a lexical epistemic adverb. The second study analyzes children’s (and adults’) multimodal expression of their knowledge state through an object guessing game by evaluating their production of prosodic, gestural and lexical cues and additionally assessing their self-assessment of their knowledge state. Results show that while preschool children are not yet able to self-report on their knowledge state, in the younger group, children encode their knowledge state through prosodic and gestural means only. And only in the older age group do children start to use a few lexical markers to signal their uncertainty. The third study uses a forced-choice paradigm to assess children’s understanding of a speaker’s politeness presented in audio only, video only and audio-visual formats. Results show that 3-year-old children detect a speaker’s polite stance significantly more through facial cues and intonation, highlighting children’s early ability to extract meaning from intonation when lexical cues are kept the same. Finally, the fourth study explores children’s multimodal production of politeness in semi-spontaneous requests in different sociopragmatic situations. Results show that regardless of the age group, children marked politeness through fine-grained gestural and prosodic means when producing requests to an adult with high social distance as compared to a classmate with low social distance, and this also depends on the cost of the request.
Altogether the results of these studies demonstrate that children’s early pragmatic comprehension and expressive abilities rely strongly on prosodic and gestural marking, developing well before children master lexical and morphosyntactic markers. More specifically, the four studies presented in this thesis bring forth evidence that both prosody and co-speech gestures play a precursor role in children’s pragmatic development of knowledge state and politeness. Ultimately, the thesis highlights the importance of approaching the study of children’s pragmatic development from a multimodal perspective.
