Which of the following is NOT a type of Augmentative and Alternate Communication (AAC)?

Augmentative and Alternative Communication (AAC) encompasses a variety of methods used to support or replace spoken or written language for individuals with communication challenges. The correct answer in this context is that sign language does not fall under the AAC category, as it is a fully developed language with its own grammatical rules and lexicon, primarily used by the Deaf community.

Sign language functions as a natural language utilized for communication among its users, rather than a method of augmenting or providing an alternative to other forms of communication. In contrast, the other options—face-to-face communication, pen and paper, and electronics—represent techniques and tools that support individuals in expressing language or thoughts when they cannot do so through speech alone. These are all considered forms of AAC because they are supplementary methods aiding communication rather than standalone languages.
