AAC Symbol Systems & Visual Supports 2 — Questions and Answers
Question 1: Which symbol system uses a combination of pictographic, ideographic, and arbitrary symbols organized by semantic categories?
- Blissymbolics (Correct answer)
- PCS (Picture Communication Symbols)
- PECS icons
- Minspeak semantic compaction
Correct answer: Blissymbolics
Blissymbolics uses a combination of pictographic, ideographic, and arbitrary symbols that can be combined to create new meanings, organized into semantic categories.
Question 2: A child with cortical visual impairment (CVI) struggles to recognize PCS symbols. Which adaptation is MOST appropriate?
- Switch to text-only AAC
- Use high-contrast symbols on black backgrounds with reduced visual complexity (Correct answer)
- Increase symbol size only
- Add more symbols to each display page
Correct answer: Use high-contrast symbols on black backgrounds with reduced visual complexity
Children with CVI benefit from high-contrast symbols on dark backgrounds with minimal visual clutter to support visual processing.
Question 3: What is the primary advantage of aided language stimulation when introducing a new symbol system?
- It eliminates the need for direct instruction
- The communication partner models symbol use during natural interactions, providing input without requiring output (Correct answer)
- It replaces verbal speech entirely
- It works exclusively with high-tech AAC devices
Correct answer: The communication partner models symbol use during natural interactions, providing input without requiring output
Aided language stimulation provides naturalistic modeling by partners who point to symbols while speaking, building symbol comprehension without demanding production.
Question 4: Which characteristic distinguishes iconic symbols from opaque symbols in AAC?
- Iconic symbols require literacy skills while opaque symbols do not
- Iconic symbols visually resemble their referents, making them easier to learn without instruction (Correct answer)
- Opaque symbols are always more motivating for users
- Iconic symbols are only used in low-tech systems
Correct answer: Iconic symbols visually resemble their referents, making them easier to learn without instruction
Iconic symbols have a visual resemblance to what they represent, which supports faster learning, especially for individuals with cognitive disabilities.
Question 5: A team is designing a visual schedule for a student with ASD. Which format is MOST likely to promote independence?
- A verbal description of daily activities posted on the board
- A left-to-right or top-to-bottom sequence of photos or symbols the student can manipulate by moving completed items (Correct answer)
- A calendar grid with written activity names
- A list of rules about daily routines
Correct answer: A left-to-right or top-to-bottom sequence of photos or symbols the student can manipulate by moving completed items
Manipulable visual schedules (e.g., moving symbols to a 'done' pocket) provide active engagement and clear completion cues that support independence.
Question 6: In Minspeak (semantic compaction), how does a single icon function?
- Each icon represents exactly one word with no ambiguity
- A single icon can represent multiple concepts depending on its sequence with other icons (Correct answer)
- Icons are used only for nouns and verbs
- Each icon maps to a single grammatical morpheme
Correct answer: A single icon can represent multiple concepts depending on its sequence with other icons
In Minspeak, icons are multi-meaning and acquire specific meanings based on their sequential combination with other icons, allowing a small symbol set to encode a large vocabulary.
Question 7: Which of the following BEST describes a 'core vocabulary' display in an AAC symbol system?
- A display containing only nouns for labeling objects
- A display featuring high-frequency, grammatically diverse words used across many contexts (Correct answer)
- A display customized exclusively for a single activity
- A display organized by body systems for medical settings
Correct answer: A display featuring high-frequency, grammatically diverse words used across many contexts
Core vocabulary displays feature high-frequency words (verbs, pronouns, prepositions, adjectives) that are used across diverse contexts and form the basis of flexible communication.
