Which symbol system consists of abstract, rule-governed graphic symbols that can be combined to generate novel meanings?
Answer: Blissymbolics
Blissymbolics is a semantic-based, rule-governed symbol system in which individual symbols combine to create novel meanings.
Eye-gaze technology is MOST critical for individuals who have:
Answer: Very limited or no functional voluntary motor movement except eye movements
Eye-gaze access is designed for individuals whose most reliable voluntary movement is eye gaze, such as those with ALS or high-level spinal cord injury.
A practitioner describes an AAC system as 'portable, durable, no charging required, and immediately available.' These features are hallmarks of:
Answer: Low-tech or no-tech AAC systems
Low-tech and no-tech AAC systems — such as boards and books — are always available, require no battery, and are often highly durable.
The AAC feature that allows a device to predict the next word a user may want based on prior selections is called:
Answer: Word prediction
Word prediction uses context and frequency data to suggest likely next words, reducing the number of selections needed.
A clinician recommends semantic compaction (Minspeak) to speed up communication rate. What is the core principle of this method?
Answer: Assigning multiple meanings to the same icon sequences to generate vocabulary
Semantic compaction (Minspeak) assigns rich, multi-meaning icons that combine in sequences to produce a large vocabulary from a small number of keys.
Which AAC feature reduces the motor load on a user by automatically completing a word once enough letters are entered?
Answer: Rate enhancement via word prediction
Word prediction offers completed words after a user enters initial letters, reducing keystrokes and physical effort.
When selecting an AAC access method, which assessment domain is MOST directly evaluated to determine if direct selection is appropriate?
Answer: Motor control and movement accuracy
Direct selection requires sufficient motor control and accuracy to isolate and activate specific targets, so motor assessment is primary for this decision.
