Features in sign language combine to form words: signers have categorical perception of features like handshape (i. e. please [hand open] while sorry [hand closed]) and location (i. e. onion [up] vs. apple [down]) There"s no inherent deficit in language ability for deaf children. ~syntactic development in blind children: same as that of sighted children. +some differences due to mother"s input (fewer questions, more commands), which leads to late auxiliary verb (has, is) acquisition. +differences in motherese leads to differences in late auxiliary verb acquisition. ~lexicon development in blind children: blind children have fewer words for things that can be seen but not touched (like flag, moon). They have more words for things associated with auditory change.
