Which choice represents a limitation regarding the use of PECS for communication?

The correct choice highlights a significant limitation of the Picture Exchange Communication System (PECS), which is that it may delay speech development in some individuals. While PECS is an effective method for facilitating communication, particularly for non-verbal children, relying solely on this system can result in a dependency on visual supports instead of encouraging verbal communication. This can be particularly problematic because the ultimate goal of many communication interventions is to promote spoken language, especially in children who have potential for speech development. Consequently, if children use PECS as their primary means of communication, they might not explore verbal communication opportunities or practice their speech skills actively, which could hinder their speech development progress over time.

Understanding this limitation is crucial for practitioners and caregivers who implement PECS, as they must balance the immediate benefits of effective communication with the long-term goals of fostering verbal communication skills. This awareness can help guide their approach and decisions regarding intervention strategies in supporting these children's overall communication development.
