Parents can use alternative and augmentative communication (AAC) to improve their child's ability to communicate.
This study was designed to see if a parent could do a good job using AAC at home. The authors looked to see how AAC changed the daily routine of a 4-year old boy with autism. They found that when the parent was taught AAC, she tended to use AAC as her main approach to working with her son. For example, she increased her use of the AAC system to ask questions. The authors found that the boy used more gestures and more spoken words at the end of the 20 sessions.
