Singularidades na construção da sincronia gestuo-vocal: interações mãe-criança com e sem atraso de linguagem

Abstract

The linguistic perspective dedicated to understanding how an individual acquires language and becomes a communicative being who uses a multimodal language has been gaining ground significantly in recent years of research into language acquisition. This look dedicated to this phenomenon was developed, among other epistemological possibilities, through an interactionist framework. Our research aims to understand gesture-vocal synchrony in the mother-infant dyad, between 3 and 17 months, in contexts comparing a case of language delay and a case of typical development. We also highlight, through data analysis, the importance of the interaction context, which can be an influencing factor during the acquisition process as a whole, in this interaction context. The data were extracted from the UFSM corpus (Profª Ana Paula Ramos) in partnership with the Speech and Writing Acquisition Laboratory (LAFE/UFPB). The corpus consists of 12 longitudinal videos of two mother-baby dyads, between 3 and 17 months old, in a clinical situation lasting approximately 15 minutes each. The corpus that makes up this longitudinal study comes from the research project “Comparative Analysis of the Development of Premature and Term Babies and their Relationship with Psychic Risk: from detection to intervention”, this corpus already collected, transcribed and published was provided by the project coordinator for the development of this work. The ELAN Software (Eudico Linguistic Annotator) was used to analyze the videos based on the Multimodal Envelope proposed by Ávila Nóbrega (2010). During the analysis, it was possible to observe the presence of multimodal language, the signs expressed corresponding to the age group observed, the relevance of the mother to the language acquisition process and Joint Care as a privileged place in the language acquisition process, corroborating the attunement of the dyad's dialogue.
