A influência da interação do cuidador na expressão de gesto e fala da criança: um estudo de caso

Children’s language encompasses an inseparable mix of gestures, looks, verbal expressions, and vocal production. In this context, the question is how the interactional environment contributes to language acquisition development. This study aims to analyze joint attention scenes between father and daughter to identify the caregiver’s role in the development of a child’s gestures and speech. The methodology is based on the construction of the Multimodal Envelope, which corresponds to the look-gesture-vocal production set, through which a video is analyzed in which the father encourages his daughter’s storytelling. As a result, we obtained an overview of how the child’s speech and gesture support is strengthened by the father’s actions, exposing the daughter to interaction contexts in which she is the main interlocutor. It is expected that this work can contribute to future investigations on the importance of the caregiver in scenes of joint attention during the process of language acquisition.
