What type of communication might require AAC?

The selection of non-verbal communication due to physical or cognitive challenges as the correct answer is grounded in the understanding that Augmentative and Alternative Communication (AAC) is specifically designed to assist individuals who are unable to communicate effectively through traditional means. AAC encompasses a range of methods and tools that can support both expressive and receptive communication for those who face barriers due to physical disabilities, such as speech impairments, or cognitive challenges that hinder effective communication.

Individuals who may benefit from AAC often cannot use verbal communication effectively or at all, necessitating alternative strategies such as picture boards, communication devices, speech-generating devices, or sign language. Each of these methods allows individuals to express their needs, thoughts, and feelings in a manner that accommodates their specific challenges and enhances their ability to communicate with others.

In contrast, the other options highlight forms of communication that do not inherently require AAC intervention. For instance, verbal communication is the primary mode for many individuals, and sign language interpretation does not independently necessitate AAC devices but rather acts as a different representation of spoken words. Written communication is also not exclusive to adults or inherently reliant on AAC, as it can be used by individuals of all ages, including those who may use AAC to support their written communication needs.
