What is a Symbol?
- A symbol is something that stands for something else because of a taught association or because of resemblance to a thing, activity or concept.
- A symbol can be a gesture, sign, object, photo, product label, black-and-white graphic or color graphic.
- Augmentative and alternative communication systems use symbols.
How is a Symbol System Used?
- Symbols represent the real object in the environment or the abstract idea that is being discussed.
- Example of teaching a symbol system: An individual touches a toy car on a choice board. The individual is not given the toy car (the symbol) from the choice board, but rather is given what the toy car represents, e.g., a ride in the car, or toy cars from toy box.
