Generalização de mandos aprendidos pelo PECS (Picture Exchange Communication System) em crianças com transtorno do espectro autista

Abstract

Verbal training with the use of alternative communication is a tool for improving the social interaction of children with Autism Spectrum Disorder (TEA). The aim of this study was to promote generalization of trained mands through the Picture Exchange Communication System (PECS). Trained mands comprise the exchange of pictures with visual stimuli by the items themselves. There were 4 autists aged between 6 and 12 years old, who took part in the study. After the PECS training, the teacher and the mothers were instructed to take notes of the mands performed in school and home settings. Results have shown that 3 children met the learning criterion for PECS and that there was a generalization for other settings. The need for greater control of the variables that interfere with mand acquisitions and the children planning for generalization of environment, people and different items have been discussed.
