  4. AAC system
    • -four different components that are used to enhance communication:
    • -symbols
    • -aids
    • -strategies
    • -techniques
  5. Symbol
    • -something that stands for something else
    • -each AAC system contains symbols that are typically classified as either aided or unaided
  6. Aided symbol
    • requires a device or accessory that is external to the body to transmit a message
    • Ex:typing a message, drawing a picture, pointing to photographs
  7. Unaided symbol
    • symbols requier only one's body
    • Ex: speaking, gesturing, vocalizing, and signing to represent meaning
  8. Acoustic Symbols
    • sounds or tones processed in the auditory system to interpret meaning
    • -In AAC systems, usually morse code
  9. Graphic Symbols
    • printed symbols that are usually represented on paper, boards or computer screens
    • -Common AAC include photographs, colored line drawings, and orthographic characters
  10. Manual Symbols
    • are produced using the body
    • Ex: gestures, sign language, facial expressions
  11. Tactile Symbols
    • can be physically manipulated
    • Ex: braille alphabet, other objects
  12. Static symbols
    • do not require movement or change to understand their meaning
    • EX: a photograph or illustration
    • AAC system uses static symbols might be one in which a child point to photos in a book to request to talk

    • -AAC strategies intended to improve message transmission time, support grammatical formulation of messages, and enhance communication rates
  18. Technique
    • refers to the way in which messages are transmitted
    • -how an individual selects or accesses symbols
    • -2 types: direct and indirect selection
  19. direct selection
