This is a great article. I saw the authors present this information at a conference. This is my take-away from this article. I am not an expert - so please read the article. The use of pronouns in ASL seem relatively intuitive. Point to yourself for ME or I. Point to a person for YOU or HE/SHE. Deaf children with autism do not use pronouns as easily as other neo-types/ neo-typicals (people who do not have autism). If you suspect a deaf (or hearing) child may have autism - look at their use of pronouns. Again, please read the article. I am summarizing.
