What type of vocabulary do preliterate clients require in their AAC devices?

Preliterate clients who use AAC devices primarily require vocabulary that enables them to communicate effectively as they work towards literacy. This group typically benefits from words that are programmed using symbols, as these symbols correspond to spoken words and concepts the clients are familiar with. Using symbols helps to bridge their understanding of language and promotes communication without requiring them to read or write fluently.

The choice of programming vocabulary with symbols aligns with the goal of fostering communication and engagement for those who are still developing their literacy skills. By utilizing symbols, AAC devices can present a more accessible means for preliterate individuals to express their thoughts, needs, and desires.

In contrast, full sentences, complex phrases, and single letters may not be suitable for preliterate clients, as they may not yet have the cognitive or language development necessary to understand and generate these more advanced forms of communication effectively. The focus is on building towards literacy, and symbol-based vocabulary facilitates this process.
