What is an observation regarding the complexity of communication with PECS?

The chosen answer highlights the effectiveness of the Picture Exchange Communication System (PECS) in addressing the communication needs of non-verbal children, allowing them to express themselves in a meaningful way. PECS serves as a visual communication tool, enabling individuals who may struggle with verbal expression to effectively communicate their needs, thoughts, and desires through the use of pictures. This method not only supports basic communication but also fosters an understanding of the structure and complexity of language.

By utilizing PECS, teachers and therapists can work with non-verbal children to gradually increase their communication skills. This can include building vocabulary, understanding sentence structure, and advancing to more complex forms of communication, such as combining symbols or constructing sentences. Thus, using PECS as a foundation allows for the development and enhancement of communication complexity for those who might otherwise have difficulty.
