What is AAC? What is Augmentative? What is Alternative?
Augmentative Alternative Communication
AAC is a set of tools that assists individuals that cannot rely solely on speech for communication.
Augmentative - it’s the methods or systems that augment or enhance individuals existing communication abilities.
Alternative - alternative means or method of communication that replaces speech when it is not possible for an individual.
What is the ultimate goal of AAC intervention?
The ultimate goal of AAC intervention is not to find a technological solution to communication problems but to enable individuals to efficiently and effectively engage in a variety of interactions and participate in activities of their choice.
CCNs
Complex communication needs
Who uses AAC?
No specific demographic persian relies on AAC
All age groups and socioeconomic, ethnic, and racial backgrounds
Who supports those who rely on AAC?
What is core vocabulary?
Words or messages that are commonly used by a variety of individuals and occur very frequently (e.g., Verbs, adjectives, prepositions, pronouns, articles, conjunctions)
80% of what we say throughout the day
What is fringe vocabulary?
Vocabulary words and messages that are specific or unique to the individual
Serve to personalize the vocabulary included in the AAC system
Recommended by informants who know the AAC user
20% of what we say throughout the day
What are unaided systems?
Aka “NO TECH”
Do not require external tools or technology
Rely on the individual’s gestures, vocalizations, verbalization, eye gazing, or even facial expressions
What are aided systems?
Low-tech systems
High-tech systems
What are low-tech systems?
Do not require a power source.
Includes communication boards, PECS, partner-assisted scanning
Usually a static displace given the nature and medium used (printed)
What are mid-tech or light tech systems?
Involve some sort of power or energy source
Usually a static, non-changing display → doesn’t change in the device itself , but the clinician can change the display.
Alternatively called “light tech”
Example: Big Mack
What are high-tech systems?
Require electronic power source and have dynamic (changing) displays. Not rigid, not fixed, rarely hybrid
Often computerized and involves screens (e.g., touch chat)
What are symbols?
Symbols represent a broad category; includes any representation of something
What are icons?
Specific type of symbol, characterized by visual resemblance
All icons can be symbols, but not all symbols are icons. True or False
t
What is iconicity?
Iconicity is a measure of how much a symbol looks like or represents what it’s supposed to represent.
An iconic symbol is a type of symbol in AAC that visually represents the object or concept that it represents. True or False
True
The symbols that you use are very very close to your referent; kahit na ‘di mo makita yung referent or the actual object you know what the person is talking about or you know what’s the idea of the message or the context
Transparent
You could still see an association between the symbol and the referent but you also have to identify the patient’s lived experiences, context, or exposure in the symbols you’ll use. This is for them to be able to comprehend whatever translucency symbols you’ll place in their AAC.
Translucent
This is the opposite side of the spectrum; the symbols that you use are more abstract or when you see the symbols you don’t readily see how this is associated with its referent; kung makikita mo yung symbol ang layo layo niya sa kung anong itsura ng referent
Opaqueness
What are the myths about AAC?
Prerequisite skills such as understanding of cause and effect or showing communicative intent must be demonstrated before considering AAC
Research suggests that impaired cognition does not preclude communication. AAC communication can help develop functional communication skills, promote cognitive development, and even provide foundation for literacy.
Introducing AAC will reduce a person’s motivation to improve natural speech and hinder language development.
Research has shown that AAC does not interfere with speech development; instead, it can actually support and enhance communication, language development, and even speech in many cases. AAC provides an additional tool for communication, not a replacement for speech. It enables individuals to express themselves when speech is difficult or limited, which can reduce frustration and increase overall communication competence. AAC can encourage individuals to communicate more often, even if it’s through non-verbal means initially. When people are able to communicate effectively, they are more likely to be motivated to continue practicing speech and language skills.
Young children are not ready for AAC and will not require it until they reach school age.
Early implementation of AAC can aid in the development of natural speech and language, and it can also help increase vocabulary for children as young as 3 years old.
