Repetição em aquisição de linguagem: notas sobre o espelhamento sonoro infantil e a ecolalia no autismo.

The main objective of this article is to investigate the importance of sound segment repetitions in vocal expressions by children without difficulties, confronting them with echolalic utterances of children with some type of difficulty in their linguistic course, especially children / adolescents diagnosed as autistic. It is intended to research how these sound repetitions are characterized and what their implications would be in the constitution of the speaking subject, having as theoretical foundation, contributions from authors whose proposals serve as the basis for the intertwining between language acquisition studies and the psychoanalytical approach. The analysis of these repetitions brings up the question of the mark. [ABSTRACT FROM AUTHOR]
