title: Maternal expression of communicative intentions and pragmatic fine tuning in early infancy.
abstract: This study focuses on pragmatic characteristics of infant-directed speech and pragmatic fine tuning during the first 18 months of life. The subjects of the study were a mother-child dyad involved in a longitudinal/observational study in a familial context. Audiovisual recordings were transcribed according to the conventions of the Child Language Data Exchange System (MacWhinney, 2000; MacWhinney & Snow, 1990). The Ninio and Wheeler's (1988) system for coding communicative intentions was adapted. The results of this research show that most of the communicative exchanges identified at 14, 20 and 32 months by Snow, Pan, Imbens-Bailey, and Herman (1996) appear in mother-child interaction from the beginning, while other communicative interchanges appear later. With respect to speech acts, the results highlight, from an early age, the general tendencies discussed by Snow et al. and some novelties. Interestingly, changes in some pragmatic measures were identified around 8 months of age, and the appearance of new communicative interchanges also took place around this age. These changes are interpreted as maternal adjustments to the child's communicative competence.
