As children developlanguage the way they communicate with others changes. Children will often simplify their
speech to accomodate the language learning of other children.This phenonmenon can occur at about 3 years of age ( Siegler,&
Children can also communicate using words that are not heard.Deaf children often communicate
using sign language.
Sign language is used by different people worldwide and it changes from culture to culture.The form we are most familliar
with is American Sign Language (ASL).
ASL is comprised of many different words and lots of complex grammar ( Siegler,&Alibali,2005).Both deaf
and hearing children develop grammar at simmilar ages, and both babble at simmilar ages ( Siegler,& Alibali,2005).
When first learning signs children can most accurately produce the location of a sign, followed by its movement .Children
are often least accurate at producing the hand shape for letters or words( Bonivillian,&Siedlecki,as cited in Siegler,&Alibali,2005).
