what are the two different classifications of iconicity
transparent(clearly the symbol represents the word) and opaque (does not represent at all)
what is iconicity
how closely a symbol resembles the word it represents
What is a stronger predictor of rate of learning than the iconicity of a graphic symbol?
motivation and reinforcement
What are the three different selection sets for AAC
- visual set, most common with pictures and objects
- auditory set, hears the selection and chooses usually for those with a visual impairment
- tactile, for those with visual and auditory impairments, feeling the object on a board
what are the considerations of AAC?
symbols (unaided or aided) Selection design sets (visual auditory or tactile) interface ( direct selection or scanning) organization of the symbols (taxonomic grid, or visual display scene)
what is interface?
how an item is selected
what are the two different types of interfaces
direct selection (directly pointing, eye tracking) and scanning ( cursor moves in a predictable pattern, and requires person to hit switch when cursor gets to the symbol)
AAC communicators, communicate at a rate ______ slower than regular speaking rates
15-25 times slower
what is the solution to slower speaking rates
encoding, consolidating frequently used phrases into one button.
what are the two different ways to organize a symbol set
taxonomic (more advanced with several pages, one button clicks into more pages) and visual display scene (more connected to real life of the client)
what does it mean when a symbol is
in the middle between opaque and

Language and literacy assessment, what is evaluated?
receptive language, can the person understand how words are combined?
reading abilities, writing and spelling skills
symbol assessment? what do we look at? and what are the two btypes?
basic (understanding the basic use of symbols, their functionality, how to point to symbols when we need them) advanced ( combining symbols into word classes and phrases and categorization of symbols)
sensory and perceptual assessment? what do we measure?
