Document Summary

These babies begin with something that looks like babbling. Special case because babies were in rich, all signing environment growing up the same way children with full hearing do. Incredibly fast development in the rst few years. The brain growth often peaks at this point which is the reason for the ability to learn language so fast. Occurs generally to around the age of 12, not determined exactly because of dif culty to observe. The exposure to human language is necessary during this period in order for full language development to occur. For example: genie, the girl who was neglected and not spoken to. There is an apparent loss as we go through development. Phonemic differences can occur in different languages. These differences tend to not be detectable to adults but detectable to infants. Research on when we stop hearing phonemic differences. Baby was conditioned to turn head when they heard this difference.
