In AAC, which of the following best defines symbols?

• A. Something visual, auditory, and/or tactile that represents something else.
• B. A physical object used to transmit messages
• C. A method of transmitting a message
• D. A strategy for communication

Answer: (A)

In AAC, symbols are representations that stand for objects, actions, or ideas, and they can be visual, auditory, or tactile. They’re used to convey meaning when someone’s speech isn’t available or is limited, and they include things like pictures, icons, written words, signs, or tactile marks. A symbol is about the meaning it represents, not the physical object itself used to send the message, the act or channel of transmitting the message, or a broad communication strategy. So the best definition is a representation that can be visual, auditory, or tactile and stands for something else.
