RESUMO

Is provided that the overall development of children with Down syndrome (DS) occurs with delay, reflecting the cognitive, social, self-care, motor and language skills. Significant differences in the usual pattern of language acquisition of children with DS have yet to be scaled. Despite the extensive body of knowledge about DS and communicative performance, especially at the international level, there are considerable gaps in understanding these processes. The purpose of this study was to check and analyze the performance of receptive and expressive vocabulary of children with DS and compare with the performance of children with typical development (TD) matched for dental age (Stanford-Binet) and sex. Were fulfilled the ethical aspects. Study participants were 20 children with DS (experimental group - EG), of both sexes, with age varying between 36 and 71 months and 20 children with TD (control group - CG), with age varying between 13 and 44 months. Was performed an interview with those responsible and apply to the Inventory of Development Communication Skills MacArthur (MacArthur). The evaluation procedures used were the Communicative Behavior Observation (CBO), the Peabody Picture Vocabulary Test (PPVT), the Child Language ABFW Test - Vocabulary Part B (ABFW) and Development Screening Test Denver II (Denver II). Statistical analysis was conducted using parametric and nonparametric tests. The results showed a statistically significant difference between the performance of GE and GC for all tests, except for the personal-social and gross motor Denver II instrument and expressive vocabulary of MacArthur. With regard to receptive and expressive skills, performance on receptive vocabulary was better than the expressive vocabulary for both groups. In the correlation between the instruments applied, no statistically significant correlation was found for performance on MacArthur and PPVT to CG and EG and the Denver II and PPVT only for GC. Analyzing the performance of children with DS was found to change as receptive and expressive vocabulary. Comparing the performance of DS children with TD children, matched by sex and mental age, it was found that children with DS showed lower performance on the receptive and expressive vocabulary, with distinctions in their response patterns.
