The Picture Exchange Communication System (PECS) teaches children with autism functional communication. This behavior-based approach rapidly builds sentence structure for requesting and commenting, aiding speech development.

Area of Science:

  • Developmental Psychology
  • Applied Behavior Analysis
  • Augmentative and Alternative Communication

Background:

  • Autism and related developmental disabilities often impair functional communication.
  • Traditional methods may not foster self-initiating communication effectively.
  • Applied behavior analysis (ABA) principles inform effective communication interventions.

Purpose of the Study:

  • To introduce the Picture Exchange Communication System (PECS) as a functional communication strategy.
  • To highlight PECS's advantages over imitation-based and symbol selection methods.
  • To review PECS's impact on social behavior, behavior management, and speech development.

Main Methods:

  • PECS utilizes icon exchange to build communication skills.

Related Experiment Videos

  • The system prioritizes teaching requesting before responding or commenting.
  • It progresses from simple icon exchange to sentence structure development.

    • Main Results:

    • PECS facilitates rapid acquisition of self-initiating communication.
    • The system enables the development of sentence structure and attribute understanding.
    • Potential positive correlations with social approach and speech co-development are noted.

    Conclusions:

    • PECS offers a structured, behaviorally-based approach for communication intervention in autism.
    • Its emphasis on requesting and sentence building supports functional communication.
    • Further review is needed on PECS's broader impact on behavior and speech.
