ABSTRACT:

The aim of this paper is to characterize the variability in the forms of language acquisition and to analyze the means of verbal production, focusing on the role of social interaction. As opposed to a model based on the description of absences, symptoms, and deviations, we have adopted a dynamic and procedural point of view in the investigation of language, considering the subject, their history, social environment and development condition. The research consisted in the follow-up of fve children aged two to four years with indications related to speech acquisition. The sessions were video-recorded, and the data were constructed based on the description of the acquisition process involving the production of children in a clinical context. We have perceived that language acquisition processes are intertwined with the account in the constitution of singularity of the subjects, and that various organic, psychic, and social factors affect language development and personality formation. In the analyses, we draw attention to the mosaic of communicational resources that is revealed when we confront the cases and examine the acquisition components that are different from each other and that are similar. We have found that, in addition to language alterations, it is necessary to focus on the peculiar uses of language resources.
