Em alguns casos do Transtorno do Espectro Autístico (TEA) ocorre, nos primeiros anos de vida, perda de palavras recém-adquiridas, fenômeno denominado “regressão da linguagem”. Para investigar esse fenômeno foram desenvolvidos três estudos. O primeiro objetivou revisar a literatura acerca da regressão. Observou-se uma lacuna quanto a explicações teóricas sobre o fenômeno e seu impacto no desenvolvimento posterior de indivíduos com TEA. O estudo seguinte propôs-se a identificar as características da regressão e da sintomatologia de crianças com TEA. A perda de habilidades ocorreu em 20% das crianças, sendo o direcionamento da atenção e a conversação recíproca alguns dos comportamentos mais comprometidos. O terceiro estudo investigou o efeito da regressão da linguagem no desenvolvimento sociocomunicativo posterior de crianças pré-escolares com TEA. Não se observou diferença estatisticamente significativa, nessa área desenvolvimental, entre os grupos com e sem regressão da linguagem. Os achados dessas pesquisas são discutidos à luz da abordagem sociopragmática. / In some cases of Autism Spectrum Disorder (ASD), in the first years of life occurs the loss of newly acquired words, a phenomenon called "language regression". To investigate this phenomenon three studies were developed. The first one aimed to review the literature on regression. It was noticed a gap of theoretical explanations about the phenomenon and its impact on the overall development of individuals with ASD. The next study intended to identify the characteristics of regression and symptomatology of children with ASD. The loss of skills occurred in 20% of the children. The abilities of directing attention and reciprocal conversation, among others, were more impaired. The third study investigated the effect of language regression on the subsequent social-communicative development of preschool children with ASD. It was not observed any statistically significant difference in this developmental area, between the groups with and without language regression. The findings of these researches are discussed in light of the socio-pragmatic approach.

Studies on the incidence of socio-pragmatic competence in the teaching of mother tongues are very scarce. The aims of this qualitative study are two folded: First, we want to describe the teachers’ use of socio-pragmatics in the subject of Spanish as a mother tongue. In addition, we want to determine the degree of use of socio-pragmatics u in this specific subject. a mixed method was applied. The results were obtained by means of aclassroom’sssemi structuredsIt was assumed that there would be a sociopragmatic approach in the teaching of mother languages but it was found to be different in each class and it depended on the teachers’ academic training and on the teaching materials, which do not always met the requirements of the subject’s curriculum. The present study assumes that there is a big difference between what appears in the curricular plan and what happens inside the classroom. Sociopragmatic aspects are not sufficiently reflected in the pedagogical practice due to two main reasons: on the one hand, internal and external factors that affect teaching negatively; and, on the other, the fact that teachers are not sufficiently acquainted with socio-pragmatic views. The results show that in all classes the teaching of socio-pragmatic aspects works although mostly intuitively. The degree of employment of socio-pragmatics is different depending on the knowledge that the teacher has about socio-pragmatic competence. Finally, yet importantly, it was found that various internal and external factors affect mother tongue teachers. These factors have a big impact on the properly development of the subject and, specifically, on the teaching of socio-pragmatic competence.
