The Deaf Lerner’s Language Development, Part 1
- ASL Rose: Two Deaf Babies
o Both babies deaf
o First mom uses spoken language
▪ No graduation pictures on wall
▪ Limited
▪ Feels like they don’t have any opportunity to earn an education
▪ Color is darker/blue almost leaning towards depression and less of a deaf
identity
o Second mom uses signed language
▪ Graduation picture and degree as well as trophies
▪ Not limited
▪ Has any opportunity can take on
▪ Color is more lit up in the room leaning towards a meaning of a more
profound deaf identity
- Through Your Child’s Eyes: American Sign Language
o Access to language from an early age is essential
o Helps build a relationship with your child
o Helps give them access to more in their own community
- The Deaf Learner’s Language Development
o Laura-Ann Petitto (2005) claims that, “Deaf children… acquire language on
identical milestones and timetables as hearing children. These children… when
exposed to signs from birth… achieve every milestone in human language
acquisition on their identical timetable.”
o The human speech is not privileged in the human brain: “The hearing tissue is not
just for hearing” (Petitto, 2005).
o The phonological patterns retrieved from spoken and signed languages are
process in the very same brain region:
▪ Auditory Cortex
• Phonological Patterns
o ASL Parameters
▪ Hand Shape
▪ Non-Manual Markers
▪ Location/Space
▪ Movement
▪ Palm Orientation
o English Learners (12+ years of Experience)
▪ All three groups had learned English in school at comparable ages
between 4-13 years

Through your child"s eyes: american sign language profound deaf identity: access to language from an early age is essential, helps build a relationship with your child, helps give them access to more in their own community. The deaf learner"s language development: laura-ann petitto (2005) claims that, deaf children acquire language on identical milestones and timetables as hearing children. Language (not english: a strong and early l1 (either signed or spoken) clearly benefits l2 acquisition, results. Low levels of performance in l2 performance in l2 english. English: signing adults (20+ years of experience, both groups were first exposed to asl in school at comparable ages of 9- Low levels of performance in asl (comparable to early signers: late l1 acquisition l2 acquisition (there"s no foundation) Critical period hypothesis: eric lenneberg (1967) refers to the critical period hypothesis (or cph) as an. Ideal period for language acquisition and development (as cited in easterbrooks and baker, 2002, p. 78).
