To effectively modify the Picture Exchange Communication System (PECS) for a 6-year-old with severe autism, apraxia, and echolalic tendencies, the following structured approach is recommended:

1. Enhance Visual Supports

  • Core Communication Board: Introduce a core board with Velcro for easy manipulation, incorporating visual cues and checklists to aid in understanding communication sequences.
  • Magnetic Board: Use a magnetic board for easier handling, allowing the child to combine pictures (e.g., noun + verb) without fine motor strain.

2. Incorporate Echolalia

  • Echoed Phrases as Symbols: Convert frequently echoed phrases into visual symbols, such as using "I want" as a picture or recording his voice for playback, enhancing engagement.

3. Augmentative and Alternative Communication (AAC) Integration

  • Speech-Generating Device (SGD): Combine PECS with an SGD to provide auditory feedback, encouraging purposeful communication and reducing echolalia.

4. Motivational and Behavioral Strategies

  • Preferred Items: Use high-interest items (e.g., cars) as rewards to motivate communication.
  • First-Then Boards: Implement to help with transitions and reduce anxiety by showing upcoming activities.

5. Positive Reinforcement and Problem Behavior Support

  • Token System: Reward correct sentence use with tokens leading to rewards.
  • Break Symbols: Provide a "break" symbol for expressing frustration, reducing problem behaviors.

6. Generalization and Consistency

  • Portable PECS Book: Create a portable book for use across environments.
  • Team Training: Ensure consistent PECS use by training family, teachers, and therapists through regular meetings.

7. Data Collection and Flexibility

  • Progress Tracking: Maintain logs of successful exchanges and challenges to guide adjustments.
  • Adaptability: Stay flexible, adjusting strategies as needed and celebrating small successes.

8. Physical Accessibility

  • Easy-to-Handle Symbols: Use larger pictures or digital PECS on a tablet if motor skills are a challenge.

9. Transition to Sentence-Level Communication

  • Gradual Introduction: Start with simple phrases (e.g., "I want [item]") and use visual aids to demonstrate sentence structure.

10. Leverage Echolalia as a Bridge

  • Echoed Phrases to PECS: Use echolalia to prompt PECS use, helping the child connect words with pictures.

By integrating these modifications, the child can transition more smoothly to sentence-level communication, supported by a consistent, engaging, and adaptable approach.
