HUBNER, Eduarda Patussi  and  ARDENGHI, Luciana Grolli. Maternal input and language acquisition: Analysis of communicative mother-child dyads. Bol. psicol [online]. 2010, vol.60, n.132, pp.29-43. ISSN 0006-5943.

This work is about the mother-child verbal interaction, aiming to study the extension and amount of mother’s directive utterances upon language development, with or without delay in the acquisition of verbal language. Eight children of both genders, whose ages varied between 2:10 and 5:3 years, accompanied by the mothers, participated in the research divided in two groups. One group was composed by four children who showed delay in the acquisition of verbal language and the remaining four who had normal development of language acquisition. Three tasks were proposed for analysis of linguistic interactions of the dyad. MLU and directives utterances of mothers were obtained. The statistical analysis was made in order to obtain the relevance of each item. It was found that the MLU, in this study, was not a measure reflecting differences in directed speech to the child in both groups; the variable that better reproduced the difference in the mother’s input was the directive utterance.

Keywords : Language; Language disorder; Linguistic input; MLU.
