RESUMEN
Vocabulary learning reflects the language experiences of the child, both in typical and atypical development, although the vocabulary development of children who use aided communication may differ from children who use natural speech. This study compared the performance of children using aided communication with that of peers using natural speech on two measures of vocabulary knowledge: comprehension of graphic symbols and labeling of common objects. There were 92 participants not considered intellectually disabled in the aided group. The reference group consisted of 60 participants without known disorders. The comprehension task consisted of 63 items presented individually in each participant's graphic system, together with four colored line drawings. Participants were required to indicate which drawing corresponded to the symbol. In the expressive labelling task, 20 common objects presented in drawings had to be named. Both groups indicated the correct drawing for most of the items in the comprehension tasks, with a small advantage for the reference group. The reference group named most objects quickly and accurately, demonstrating that the objects were common and easily named. The aided language group named the majority correctly and in addition used a variety of naming strategies; they required more time than the reference group. The results give insights into lexical processing in aided communication and may have implications for aided language intervention.

The present study was carried out from March 2000 to June 2005 by interviewing many people from several parts of Brazil. It was aimed at assessing the level of knowledge on technical graphic symbols used for identification of commands and operation controls, and support in agricultural machines. The main customers involved in the process from the project of the agricultural machine to its use and support were interviewed. Results suggest that the knowledge of the graphic symbols meaning is quite reduced among the main customers involved in the process.
Este trabalho foi realizado no período compreendido entre março de 2000 a junho de 2005, com entrevistados de várias regiões do Brasil, e teve por objetivo realizar uma pesquisa analítica a respeito do grau de conhecimento sobre símbolos gráficos, para a identificação dos comandos e controles de operação e manutenção em máquinas agrícolas, dos principais clientes envolvidos no processo, desde o projeto da máquina agrícola até sua utilização e conseqüente manutenção. Os resultados encontrados indicam que o conhecimento sobre o significado que possuem os símbolos gráficos utilizados para caracterizar comandos e controles de máquinas agrícolas é bastante reduzido por parte dos principais envolvidos no processo.
