What are Evidence-based Alternatives to Vocal Communication in Aba?
When vocal speech is not the primary or most effective communication method for a child, Functional Communication Training (FCT) utilizes several evidence-based alternatives known as Augmentative and Alternative Communication (AAC). These tools serve as a replacement behavior, allowing the child to express their needs and reduce frustration.
The following are the primary evidence-based alternatives to vocal communication:
- Picture Exchange Communication System (PECS): This is a low-tech system where a child learns to hand a specific picture card to a communication partner to make a request. It is often best suited for nonverbal children or those with limited motor skills.
- Speech-Generating Devices (SGD): These are dynamic electronic devices, such as an iPad with a specialized AAC app, that produce voice output when a child selects a symbol or word. They are highly adaptable and can grow with a child’s vocabulary.
- Sign Language: Using American Sign Language (ASL) or modified signs provides a manual way to communicate without the need for additional equipment. This method is effective for children with strong motor imitation skills.
At Golden Touch ABA, Board Certified Behavior Analysts (BCBAs) conduct assessments to determine which of these modalities best fits a child’s unique strengths and family environment.
