What is it about?
In this study, we analyzed the use of manual signs (i.e., ASL signs and communicative gestures) by a group of 19 hearing children with CAS who attend a school pro- gram where they receive instruction in both English and SSS. Results indicated children with CAS whose oral expressive language was relatively more impaired produced the most supplementary signs, suggesting that children with oral expressive language challenges are more likely to rely on them for communicating words they cannot yet speak.
Why is it important?
Overall, our findings support the use of SSS as an augmentative communication method for children with CAS: The majority of the children in our study used manual signs successfully.
