AAC Components Flashcards
FOUR COMPONENTS OF AAC
Symbols, Aids, Techniques, Strategies (SATS)
Representation of the idea through unaided and/or aided means
Symbols
Assistive devices or means to transmit and/or receive messages
Aids (Device)
Productivity and efficiency of message transmission
Strategies
Access and choices of messages
Techniques
represents something else by association, resemblance, or convention
Symbols
something else is termed the ____ and might include vocabulary concepts such as people, actions, objects, places, descriptors, questions, social words, and so on.
Referent
Symbols that the human body can produce (i.e, gestures, signs, finger spelling, etc.)
Unaided Symbols
Symbols that needs external tools to produce messages
Aided Symbols
Symbols that needs external tools to produce messages
Aided Symbols
What are the Unaided Symbols?
Gestures, Eye-gaze related symbols or messages, Manual Sign, Natural speech and vocalization
What are the aided symbols
Object and object symbols, Graphic Symbols
Perceptual Characteristics of Aided Symbols
Complexity, Perceptual Distinctness, Degree of Ambiguity, Size
referred to the number of semantic elements or sophistication of the graphic symbol
Complexity
Degree to which a symbol seems obviously different and distinct from others within a given symbol corpus
Perceptual Distinctness
Number of concepts a single symbol can represent
Degree of Ambiguity
Vocabulary size refers to the size of the original lexicon the symbol corpus represents
Size
Refers to the degree to which an individual perceives the relationship between a symbol and its referent
Iconicity
refers to the continuum that describes symbols by ease of recognition
Iconicity
○ Highly guessable symbols given that it is visually representable to its referent
○ meanings are readily available
Transparent Icons
○ Less apparent
○ Needs more information for decoding
Translucent
symbol that is not readily obvious to the user even when the additional information is provided
Opaque
3 attributes of Aided Symbols
Linguistic Capacity, Physical, and Design Attribute
What are the linguistic capacity of Aided symbols
Nonlinguistic
Prelinguistic Transitionary
Prelinguistic Symbolic
Linguistic
What are the Physical Attributes if Aided Symbols
Acoustic, Two-dimensional, Animated, Three-dimensional
What are the Designs attribute of Aided Symbols
Object, Picture, Line Drawing
Symbols that do not possess any inherent linguistic characteristics
Nonlinguistic
More defined but unsophisticated linguistic characteristic in the form of internal logic
(Prelinguistic) Transitionary Symbol System
Inherent Linguistic characteristics with limitation in the form of internal logic
Prelinguistic Symbol Set
Unlimited communication is possible
Linguistic
Symbols produced a synthetic speech through speech-generating devices (SGDs)
Acoustic
Object-based symbols
3 dimensional
Object-based symbols
3 dimensional
Symbols that require movement to assist in conveying meaning
Animated
Symbols categorized as static (i.e., those that do not include movement) and kinetic (i.e., those in which movement or animation is one their key elements)
Two Dimensional
Also referred as symbol groups due to its little to no inherent characteristics
Aided Symbols: Nonlinguistic Symbols
● Limited expansion capabilities
● Limited internal logic
Aided Symbols: Nonlinguistic Symbols
First aided AAC approach used with infants and older beginning communicators who have developmental disabilities
(1) Real Objects: First aided AAC approach used with infants and older beginning communicators who have developmental disabilities
Careful selection to the potential communicator’s impairments and abilities (i.e., size and tactile similarity)
(2) Miniature Objects:
part of the referent that share the same features
Partial
related to the referent
associated
uses concrete or “tangible” symbols
Tangible
2 dimensional
Photograph
Emoji
Generic Line
Drawing Clipart
Lower-level pre-linguistic symbols with rudimentary internal logic
Aided Symbols: Prelinguistic Symbol Sets
a visual language system organized semantically with strategies for picturing concepts with categories having common shapes and colors
Dynasms
learned by people with cognitive and/or other disabilities.
Imagine Symbols
flexibly customizable, interactive, and highly stimulating, allowing for a range of human computer user interactions available by design in association with each icon
Lingraphica Concept-Images:
aim was to develop a symbol corpus that was free of cost, and in fact, these symbols are free to use based on the creative commons license terms.
Mulberry Symbols
initially created focusing on helping people with aphasia
Participics
● Not as comprehensive in allowing symbol users to communicate freely
● More defined and more structured but unsophisticated linguistic characteristic in the form of internal logic
● Design attributes are almost always line drawings
Aided Symbols: Prelinguistic Transitionary Symbol Sets
Aided Symbols: Prelinguistic Transitionary Symbol Sets
black line drawing easy to interpret as they look like that they represent and can be easily drawn on white boards with
Makaton
one of the most commonly used aided symbol sets in the world, as the developers have kept up with the latest technology over the decades.
Picture Communication Symbols
the user learns the rules that govern the symbols so knowledge can be applied to understanding novel symbols.
Widgit
sophisticated level of aided symbols due to their sophisticated and comprehensive internal logic that allows virtually unlimited expansion capability, that is, there are no limitations in terms of creating new symbols
Aided Symbols: Linguistic Symbols
Example of Linguistic Aided Symbols
Alphabet Based Boards, Phonetic Based Boards, Line Drawing
POTENTIAL ISSUES WITH AIDED SYMBOLS
Polysemy, Sequentiality , Intrinsic Factors, Iconicity
Symbols that the human can produce
Symbols that requires does NOT need aid or assistive communication device to display and transmit message
Unaided
Symbolization of Unaided
Nonsymbolic, Transitional, Symbolic
Design Attribute of Unaided
Phonetic/Phonemic based, Alphabet based, Gestural , Sign Language, Vocalization
- Idiosyncratic gestures/ vocalizations
- Responsibility for communicative interaction rests with the partner
- May demonstrate little overt behavior
- needs more context
Non-symbolic
