The Theory Behind Symbol-It
A groundbreaking new theory, Dual-Symbol Immersion applies the most fundamental principles of language development to AAC. Verbal speakers learn to talk when they are fully immersed in verbal language.
Removing Language Limits
Second languages are learned in the same way, whether it is a second verbal language, sign language, or a symbol system. Through this basic premise, Dual-Symbol Immersion removes the limitations of traditional AAC language development in regards to symbol speakers, allowing them to develop complexity of language with full meaningful expressions.
