Final answer:
Aislin and other children with autism use an Augmentative and alternative communication (AAC) device in 'HWGA' to support their communication needs, allowing for nonverbal expression and development of language skills.
Step-by-step explanation:
The communication device used by Aislin and the other children with autism in chapter 3 of 'HWGA' is most likely a form of Augmentative and alternative communication (AAC). Option c) Augmentative and alternative communication (AAC) is correct. AAC encompasses various methods of communication that can help those who are unable to rely solely on verbal speech. This can include picture boards, sign language, and technological devices.
AAC devices are designed to assist individuals in expressing themselves when traditional verbal communication is challenging or not possible. For students like Aislin, who may have difficulty with spoken language, AAC provides a means to communicate effectively with others. The goal of these devices is to enhance and support the individual's existing communication skills, potentially enabling nonverbal communication or aiding in the development of language skills.
