In a previous blog we discussed how sign language helps develop the Broca's Area in able bodied children and how the early development of language and fine motor skills boosts a child's ability to learn later in life. While this area has been studied and the efficacy of sign language for children has been proven, what does the research say for children with disabilities and how can a child with a disability benefit from sign language?
While the efficacy of sign language for children with autism has been disputed since the 1970s we now know that sign language helps children develop fine motor skills necessary for daily activities, as well as increases development in the Brocha’s Area where language is developed in the brain. For children with autism specifically, research has shown that students' sign vocabulary size and accuracy of sign formation were highly correlated with their performance on two measures of apraxia and with their fine motor age scores. This shows that, even at varying rates, children with autism show improved communication scores.
Now what about children with physical disabilities? We know that the use of sign language can help improve fine motor skills but in general children with disabilities can utilize sign language in order to reduce typical frustrations that may be encountered on a daily basis. By expanding a child's ability to communicate we can effectively reduce barriers for that child that typically lead to isolation and decreased mental and physical health.
While proper American Sign Language may be difficult for some to use, others may find Conceptually Accurate Signed English or C.A.S.E sign language easier to sign due to reduced motor skills. In either case, introducing a child with a disability to sign language can open a whole new world to them that neither you or your child thought existed.
