Study Description
Brief Summary:
The aim of this study is to characterize the process of constitution of symbolic representation in infants with Down syndrome, as well as to investigate the relationship between gestures and the emergence of oral language. The investigators hypothesis is that children with Down syndrome could present difficulties during the constitution of symbolic representation that may be related to later deficits on expressive language, generally observed in these children.

Condition or disease
Down Syndrome

Detailed Description:
According to the Genetic Epistemology, language development is directly related to cognitive construction. Such relationship is clearly observed after the constitution of representation that allows one individual to express his or her thinking through language.
