Which aspect of communication does the PECS program primarily focus on?

The Picture Exchange Communication System (PECS) primarily focuses on using symbols for communication. This approach is designed especially for individuals with autism and other communication challenges. By using visual symbols, such as pictures or icons, individuals are able to express their needs, wants, and thoughts more effectively. The program's structure encourages users to initiate communication by exchanging a picture of what they desire for the item or activity, thereby fostering independent and spontaneous communication skills.

The emphasis on symbols is significant because it provides a visual representation of language, which can be more accessible for those who struggle with verbal communication. This method also promotes understanding and engagement, as individuals can directly relate the symbols to their experiences and desires, supporting the development of functional communication skills.

Other aspects mentioned, such as verbal chattiness, physical gestures, and listening skills, while important in the broader scope of communication, do not align with the fundamental purpose of the PECS program, which is specifically designed to utilize symbols to facilitate communication for those who may not effectively use traditional speech or are in the early stages of communication development.
