    Summary
    This summary is machine-generated.

    The Picture Exchange Communication System (PECS) teaches children with limited speech to initiate communication by exchanging pictures for desired items. This approach offers advantages over traditional methods and may support speech development.

    Area of Science:

    • Speech-Language Pathology
    • Developmental Psychology
    • Special Education

    Background:

    • Children with limited speech often struggle with functional communication.
    • Traditional communication methods may not foster spontaneous interaction.
    • Alternative/Augmentative Communication (AAC) systems offer potential solutions.

    Purpose of the Study:

    • To describe the Picture Exchange Communication System (PECS) as an AAC approach.
    • To highlight the advantages of PECS over traditional communication methods.
    • To review the impact of PECS on speech development in nonvocal students.

    Main Methods:

    • Description of the PECS training protocol.
    • Teaching children to exchange pictures for desired items.

  • Progressing to sentence construction and attribute use within requests.

    • Main Results:

    • PECS facilitates functional communication initiation within a social context.
    • The system empowers children to express desires and needs.
    • Implementation of PECS has been linked to speech development in some nonvocal students.

    Conclusions:

    • PECS provides a unique and effective method for teaching functional communication.
    • The system's social framework encourages communicative interaction.
    • PECS may positively influence the development of spoken language.
