How can I Improve Functional Communication Skills in Nonverbal Children?

Improving functional communication skills in nonverbal children involves a systematic, evidence-based approach that replaces challenging behaviors with effective ways to communicate. The process typically follows these strategies:

1. Functional Communication Training (FCT):

• Identify the Cause: A Board Certified Behavior Analyst (BCBA) conducts an assessment to determine the “why” behind behaviors (e.g., a tantrum may mean “I need a break”).
• Select a Replacement: The child is taught a specific communicative act—such as a sign, gesture, or picture—to replace the behavior.
• Provide Reinforcement: Therapists and family members provide immediate, rich reinforcement when the child uses the new skill.

1. Utilizing Communication Tools:

• Picture Exchange Communication System (PECS): Teaches children to exchange picture cards for desired items, establishing the foundation of social interaction.
• Sign Language: A motor-based path for children who are motivated by imitation and visual learning.
• AAC Devices: Electronic tablets or speech-generating devices that provide an audible voice for non-speaking children.
• Vocal Imitation Training: Systematically reinforcing attempts to imitate sounds to shape them into functional speech.

1. Natural Environment Integration:

Skills are reinforced during daily routines (like mealtime requesting) and play-based interactions to ensure the child can use their new “voice” across home, school, and community settings.
