MYTHS AND FACTS IN MORE DETAIL
Courtesy : Compiled by Octave Speech and Hearing, Bangalore
Myth 1 - “His/Her understanding is too low to use Avaz”
Fact: Expect more communication from the individual even if his/her understanding is lesser than expected and strive to achieve it. If the individual is not able to communicate at the same level as peers, his/her communication difficulties may be interfering with the ability to accurately express his/her understanding. It is better to try and then fail rather than not trying.
Myth 2 - “He/She has a tendency to throw things and damage stuff. Hence we want to wait till his/her behavior is in control before we start considering Avaz”
Fact: Inappropriate behaviors could be largely due to his/her inability to communicate leading to frustrations. This could be manifested in the form of inappropriate behaviors. Encourage appropriate functional communication and empower him/her with the ability to communicate effectively.
Myth 3 - “He/She is too young to be considered for Avaz”
Fact: No individual is too young to use Avaz. If you expect words at that particular age, then definitely consider Avaz. If he/she can select an icon and see the consequence of it, then you are ready to start. Remember that babies are immersed in language immediately, but it takes them two years to start putting words together.
Myth 4 - “He/She has enough verbal speech and can say sentences and hence doesn’t need Avaz”
Fact: Individuals with verbal speech can also be an Avaz candidate. Probably he/she has limited “routine scripted” sentences (e.g., going to park, want chocolate) and may be handling each of those sentences like one big, long word. He/she might have difficulty producing novel sentences independently. He/she can be encouraged to create sentences using different kinds of words using Avaz.
Myth 5 - “He/She has to understand symbol representation before we can introduce AAC”
Fact: Symbols are abstract to everyone. We learn their meaning through exposure and experience to associate them in our daily life. Symbol representation can be taught using Avaz. If he/she loves popcorn, his/her attempt to grab it can be directed to touching the popcorn icon on Avaz. As soon as the icon is touched, it generates a voice output; this gets rewarded by giving him/her the popcorn. With repeated attempts, he/she will understand symbol representation and its use functionally.
Myth 6 - “My child does not speak yet/does not speak well enough, however I understand my child well”
Fact: It is great that you understand what he/she wants to communicate. However, this limits his/her interactions with others and restricts his/her life. Communication attempts need to be understood by everybody. Hence it is necessary to provide a communication system that can be universally understood.
Myth 7 - “The user is on reduced screen time/no screen time. Use of an iPad and/or a tablet for communication is going to be addictive”
Fact: Use of gadgets for communication does not come under ‘screen time’. Use of gadgets (read screen time) is a solitary activity and is recreational while communication is interactive. That makes a whole lot of difference. Having said that, if you find users choosing games/youtube option than the app placed for communication, you could consider locking down with guided access or get a dedicated device for the same. Keep ‘interaction’ and ‘recreation’ separate.
Myth 8 - “Introducing Avaz will make my child dependent on it. He/she will stop trying to speak”
Fact: It is well documented that use of a communication system will not hinder speech development. In fact, it enhances communication and reduces inappropriate behaviors that may arise from frustration or communication breakdown. The right approach to intervention focuses simultaneously on use of Avaz while enhancing natural speech development in a multimodal approach
Myth 9 - “Use of communication systems including the use of Avaz will prevent the user from speaking. Or you are told/you decide to wait for a little while and see whether speech develops over time”
Fact: It is the impression that AAC will become the child's primary communication mode and take away the child's motivation to speak. The fear many parents, and some practitioners, have is simply not supported by the available empirical data. In fact, there is enough evidence to prove that it may enhance the development of spoken communication apart from reducing behavioral challenges and improving learning outcomes.

There are many common myths that can potentially affect an individual's or family member's willingness and motivation to use AAC. However, available research does not support these myths (Romski & Sevcik, 2005).
Myth 1: Introducing AAC will reduce an individual's motivation to improve natural speech and will hinder language development (including the development of social communication skills). AAC should be introduced only after the ability to use natural speech has been completely ruled out.
- The use of AAC does not affect motivation to use natural speech and can, in fact, help improve natural speech when therapy focuses simultaneously on natural speech development and use of AAC in a multimodal approach (Millar, Light, & Schlosser, 2006; Sedey, Rosin, & Miller, 1991).
- Intervention for minimally verbal school-age children with ASD that included use of an SGD increased spontaneous output and use of novel utterances compared with the same interventions that did not include use of an SGD (Kasari et al., 2014).
- AAC can help decrease the frequency of challenging behaviors that may arise from frustration or communication breakdowns (Carr & Durand, 1985; Drager, Light, & McNaughton, 2010; Mirenda, 1997; Robinson & Owens, 1995).
Myth 2: Young children are not ready for AAC and will not require AAC until they reach school age.
- Early implementation of AAC can aid in the development of natural speech and language (Lüke, 2014; Romski et al., 2010; Wright, Kaiser, Reikowsky, & Roberts, 2013) and can increase vocabulary for children ages 3 years and younger (Romski, Sevcik, Barton-Hulsey, & Whitmore, 2015).
- AAC use with preschool-age children has been associated with increased use of multisymbol utterances and development of grammar (Binger & Light, 2007; L. Harris, Doyle, & Haff, 1996; see Romski et al.  for a review).
- AAC use can lead to increases in receptive vocabulary in young children (Brady, 2000; Drager et al., 2006).
Myth 3: Prerequisite skills such as understanding of cause and effect and showing communicative intent must be demonstrated before AAC should be considered; individuals with cognitive deficits are not able to learn to use AAC.
- Measures of pre-communicative cognitive ability may be invalid for some populations, and research suggests that impaired cognition does not preclude communication (Kangas & Lloyd, 1988; Zangari & Kangas, 1997). Development of language skills can lead to functional cognitive gains (Goossens', 1989).
- AAC intervention for children with complex communication needs helps develop functional communication skills, promotes cognitive development, provides a foundation for literacy development, and improves social communication (Drager et al., 2010).

The myths of AAC are a combination of misconceptions and misinformation. Unfortunately they are both pervasive and dangerous. They may continue to be perpetuated by beliefs
- that communication must be verbal
- that AAC is restricted to specific options
- that use of AAC will prevent children from developing speech
- that there are prerequisite skills that must be developed before an individual is able to use AAC
- that AAC systems are too complex for individuals with intellectual disabilities
Not too long ago I got a call from a mother. She was interested in looking into AAC for her child, but the school district said the child was too young. How old was he? He was 6.
Last week I had the same experience. This time, however, the child was 3. As soon as I put a dynamic display device in front of her with core words to use in our play interactions she began to use the system independently to direct my actions and her choice of activities, including which colors of markers she wanted.
Too soon for AAC?
Two years ago I attended an IEP meeting for a girl for whom I was providing consultation. The school district was appalled when I suggested an AAC system as a repair strategy. She was verbal; but with a repertoire of less than 3 dozen words. Their response; “We’re not giving up on speech. It’s too soon!” How old was she? She was 9.
And note that I suggested an AAC system as a repair strategy, not as a replacement for speech.**
Busting the Myths:
Some parents and professionals believe that AAC is a last resort for their nonverbal or minimally verbal children, and should only be used when there is no more hope for developing speech.
Unfortunately, this all too often means that children (and some adults) have no means of communicating for far too long; resulting in frustration, negative behaviors, and significant limitations on their language development, access to curriculum in school, access to social interactions at home and in the community, and in adapted living skills.
Waiting too long to provide a mode of communication denies the child the opportunity to learn language, acquire vocabulary, and express himself appropriately. Waiting too long to provide an appropriate mode too often means communicating with an inappropriate mode. Research shows that any intervention delayed beyond a child’s first three years has less significant impact, and that children - including those with disabilities - learn faster and more easily when they are young. Lack of access to communication results in the individual being excluded from appropriate educational and vocational placements, restricting social development and quality of life.
Rather than being a last resort, AAC can serve as an important tool for language development and should be implemented as a preventative strategy - before communication failure occurs. Romski and Sevcik conclude that young children with complex communication needs (CCN) should receive services early in their development to augment natural speech and support development of language and communication. Withholding AAC intervention not only impacts building language skills, but also has an impact upon cognitive, play, social, and literacy skills development.
From birth babies communicate to us. We recognize these communicative behaviors and respond to them; reinforcing them and expanding upon them. We do not wait until they can speak to us to recognize and build on their communications. We do not wait until they can communicate independently to provide scaffolding for building more communication skills. Rather we interpret what they are doing to communicate and model additional possibilities. We work on building both nonverbal and verbal skills simultaneously. Similarly we can work on AAC skills and speech simultaneously.
Busting the Myths:
Parents and professionals may also believe that use of AAC will stifle the child’s potential verbal skills and/or serve as a “crutch” upon which the child will become reliant.
However, research has shown that use of AAC often stimulates verbal skills in users with the potential to be at least partially verbal.
Children need access to appropriate and effective modes of communication as soon as possible. Without an appropriate way to communicate genuine messages, individuals frequently use inappropriate behaviors to communicate, or withdraw. Struggling to learn to speak, while having no other way to communicate, leads usually to frustration.
Further, those who have access to AAC tend to increase their verbal skills. So, not only is there no evidence to suggest that AAC use hinders speech development, there is evidence that suggests access to AAC has a positive impact on speech development.
A review of research undertaken in 2003 showed that, as a result of AAC intervention, 11% of children showed no change and 89% demonstrated gains in speech. In studies those who showed no change did not decline in speech use as a result of AAC. This concept was observed for many years and reported anecdotally by speech-language pathologists and others working with AAC users. The research only backs up those observations. AAC is now cited as evidence based practice for facilitating speech in nonverbal children.
Those working with adults with acquired speech and/or language disorders have also found benefits in use of AAC to begin to rebuild communication skills. “Adults who are experiencing chronic medical conditions use assistive technology to participate in life situations and to stay connected with the world around them.” (Beukelman, Garrett, & Yorkston, 2007). AAC users have increased participation in a variety of interactions using a variety of communication functions and forms.
Why AAC use promotes speech development is not precisely known. Theories include the possibility that use of AAC reduces the physical and social/emotional demands of speech and that the symbols/words provided visually serve as consistent cues and the speech output provides consistent models. Although the goal of AAC intervention is not necessarily to promote speech production, the effect appears to be that it is a result.
Busting the Myths:
Many times parents are told children need to have a set of prerequisite skills in order to qualify for or benefit from AAC, and that their young and/or severely disabled children (and adults) do not yet possess those skills.
In addition, some professionals believe that there is a hierarchy of AAC systems that each individual needs to move through; utilizing no- or low-technology strategies before gaining access to high technology systems.
In fact, this outlook only tends to limit the type of supports provided and limit the extent to which language may be developed.
First, there are NO prerequisites for communication; everyone does it. And as we’ve seen above, all children learn to communicate before learning to speak.
Second, research does not support the idea of a hierarchy of AAC systems, and shows that very young children can learn to use signs and symbols before they learn to talk. Research has also shown that very young children with complex communication needs have learned to use abstract symbols, photographs, and voice output devices during play and reading activities.
Requiring an individual to learn multiple symbol systems or AAC systems as they develop skills merely serves to make learning to communicate more difficult.
One of the things we have learned about teaching individuals to use AAC systems is that the stability of vocabulary is important. Being able to locate the words in the same location every time they use the system significantly lightens the cognitive load of looking for the words wanted or needed for a message. The less cognitive attention that needs to be paid to finding vocabulary the more available for formulating the message. When we make the user move through a hierarchy of devices, we constantly present them with different arrangements of words; making it more difficult for them to learn.
Channeling communicative behaviors and responses into appropriate language skills requires access to appropriate tools and sufficient vocabulary.
Busting the Myths:
Many parents and professionals believe that AAC is only for individuals who are completely nonverbal. Students who have some speech skills are frequently not provided access to AAC systems in the belief that intervention should focus only on building their verbal skills.
However, if speech is not functional to meet all of the individual’s communication needs - that is, if the student does not have sufficient vocabulary, is not understood in all environments, or if speech is only echolalic or perseverative - AAC should be considered.
“Any child whose speech is not effective to meet all communication needs or who does not have speech is a candidate for AAC. Any child whose language comprehension skills are being claimed to be ‘insufficient to warrant’ AAC training is a candidate for aided language stimulation and AAC.” (Porter, & Caffiero, 2010)
The individual who says a few words or phrases needs to increase his vocabulary and communication functions.
The individual whose family and care staff can understand him may not be understood by others in the community. What happens when he is trying to communicate with someone who isn’t familiar with his communication attempts or is in a different from usual context/situation?
The individual who can repeat everything he hears - is echolalic - does not necessarily use these utterances appropriately and still cannot interact in a social, academic, or daily living exchange. What happens when he wants or needs to say something for which he does not have a store phrase, or the echolalic phrase he uses is not appropriate to the context? What would happen in an emergency situation? How do you know when something is wrong?
The individual who perseverates on a given utterance lacks the ability to formulate new utterances in the face of desiring to communicate. Once he has his partner’s attention, how does he communicate what it is he really wants to say but cannot?
None of these individuals has functional speech to meet all of their communication needs. All are potential candidates for AAC.
Busting the Myths:
When working with individuals with severe disabilities - particularly intellectual disabilities - many professionals assume the individual is too cognitively impaired to use AAC.
Kangas and Lloyd (1988) wrote that there is no “sufficient data to support the view” that these individuals cannot benefit from AAC because they have difficulty paying attention, understanding cause and effect, don’t appear to want to communicate, are unable to acquire skills that demonstrate comprehension of language, are too intellectually impaired.
Unfortunately there continues to be this misconception, and professionals continue to posit arbitrary skills that individuals must attain before providing AAC intervention. All too often professionals - and even family - underestimate the potential abilities of these individuals.
We must proceed with the notion of the “least dangerous assumption.” That is, we must proceed with the plan that, if we are incorrect, will cause the least damage to the individual.
Believing the individual can acquire communication skills, we proceed with a plan to provide an AAC system and intervention. There can be no damage from providing someone with a way to communicate. If we believe the individual cannot acquire these skills and thus do not provide an AAC system or intervention, we have done immense damage if we are wrong. Poor performance is more often related to the competence of the intervention; not of the individual.
The relationship between cognition and language is neither linear nor one of cause and effect; they are correlative. They are intertwined in a very complex way. We cannot say that a specific level of cognition or skills needs to happen before language develops. They are interdependent. We often see language skills in the (supposed) absence of expected cognitive skills.
Research and observation continue to indicate that there is no benefit to denying access to AAC to individuals with significant disabilities. Intervention should be based on the idea that learning is based on the strengthening of neural connections through experiences and that repetition of these connections through multiple modes facilitates learning. Providing users with rich experiences with their AAC systems builds on the neural patterns and facilitates communication skills building. Not providing AAC services based on preconceived ideas about the cognitive skills of the individuals simply continues to segregate and limit access to life experiences for them.
Busting the Myths:
Many school districts also subscribe to the idea (some call it a myth) that the PECS is sufficiently robust.
The Picture Exchange Communication System (PECS) is widely used in school districts as the AAC system provided to students. It is good at establishing communicative intent in a child who does not appear to demonstrate this. In fact, it originated as a way to teach children with autism how to initiate communication by approaching others.
PECS books use velcro to move symbols between their pages and the cover sentence strip.
Use of velcro means a lack of stability; pictures can be in a different location every time the child opens the book. Too much cognitive energy can be consumed by trying to find the picture wanted. Learning through motor planning, which research has shown to be effective for some is obviated by use of velcro and random vocabulary positions (think about getting into a rental car whose brake pedal is in a different place). Effective AAC users pay little attention to the symbol; rather they rely upon location and motor patterns to find vocabulary. Instability of vocabulary location can eventually lead to frustration. And the increased effort needed to use PECS will often lead to the child abandoning it.
PECS books have limited vocabulary.
I once encountered a young girl who was small and slight. She had a PECS book that was a large 3-ring binder with many pages full of velcro’d pictures. It was almost as heavy as she was. It required someone else to carry it around for her. It was an effort for her to find the word she wanted at each communicative attempt. And while teachers, SLPs and parents continued to add vocabulary to it, most of the vocabulary available was nouns. How was she expected to expand her language skills without the building blocks of syntax? Where were the adjectives (other than colors) to elaborate.
Busting the Myths:
Unfortunately, there are also those who believe that simply providing access to an AAC system will solve the communication problems of the user.
The AAC system cannot “fix” the individual or their communication difficulties. While use of AAC will facilitate development of speech or language, and of literacy skills, and will increase the individuals’ ability to communicate effectively, it will not do so simply by being there.
The AAC system is a tool and, like any tool, the user needs to know how to use it. And for most of those individuals, direct, specific, and structured intervention and opportunities need to be provided.
Users and their partners need to accept the AAC system; they also need appropriate instruction in how to use the system and how to develop effective communication and further language skills with the system.
One problem often encountered with adults with acquired communication disorders; such as stroke, ALS, or TBI, is acceptance of the device. This difficulty of acceptance can be present on both sides of the communication exchange. It is difficult for adults who have been independent communicators to accept the new and usually sudden changes in their abilities and reliance on others and on assistive tools. It may also be difficult for caregivers who have not been adequately trained to use the AAC system to accept that this is a necessary tool. They may not understand the importance of the AAC system in allowing the individual to maintain social, medical, and daily needs connections. Care givers often say, “I know what he wants,” or “Oh, I understand him.” But they cannot possibly know everything that the individual might want to say.
The success of the AAC system is not dependent upon only the individual’s skills and cognitive abilities. It is also not only dependent upon the completeness or robustness of the AAC system. It is strongly dependent upon the willingness, training, and responsiveness of partners. Partners who do not understand the need for the AAC system are less likely to respond to the individual’s communication attempt with it. If the partners have low expectations of the AAC learner, do not respond consistently, do not use aided input consistently or do not provide sufficient communication opportunities the AAC learner is not likely to progress. Communication partners have a significant responsibility.
The Myth of Augmentative and Alternative Communication (AAC) Pre-Requisite Skills
We hear a lot of reasons for not beginning high-tech Augmentative and Alternative Communication (AAC) with students who have Complex Communication Needs (CCN)…A LOT of reasons. I’ve chosen the top six and created a flow chart. I like flow charts, but for those of you who do not, I’ve also written a narrative version, with related links.
Cognition Myth: “His/Her cognitive skills are too low to learn to use AAC. The individual has the cognitive skills of a 9 month old. That system is for ‘higher functioning’ kids.”
I am starting with this myth because it is the one that makes the hair on the back of my neck stand up. These statements are demeaning, and I have heard people make comments like this in front of the student. If the individual is not able to communicate at the same level as peers, his/her communication difficulties may be interfering with his/her ability to accurately express intelligence. If this individual is currently using AAC, the system may be too limiting. Research shows that when you expect more from a child, his/her intelligence increases. Give the individual the benefit of a positive self-fulfilling prophecy.
Behavior Myth: “We have to get his/her behaviors under control and then we can consider communication. We don’t want the device to be thrown and damaged.”
If the individual does not have a reliable, effective way to communicate, he/she has no choice but to use behaviors. Appropriate, functional, comprehensive communication is necessary for “appropriate” behavior.
If this individual is currently using AAC, the system may be too limiting.
Proof of desire myth: “We’re waiting for him/her to develop more verbal speech so that we can tell if he/she actually wants to communicate.”
Acknowledge button presses as intentional communication, even if you don’t understand the relevance. Presume competence and give the individual your respect and attention as they learn the power and value of communication.
If the individual does not have access to a large expressive vocabulary, someone else has determined the (frequently small) vocabulary available to him/her. If the limited system insults the individual or doesn’t have what he/she wants to say, it is often ignored.
When you give individuals with complex communication needs (CCN) a system with an extensive vocabulary, you give them the opportunity to explore language and talk about what THEY want, and that can make all the difference. We all enjoy talking to people who share our interests or who are at least willing to listen. It is the foundation of relationships and socialization.
Hierarchy Myth: “He/She can’t use an AAC device unless the individual is able to combine 3 icons in the communication book.”
Get another opinion. Making individuals prove themselves before they are given access to a comprehensive communication system is archaic. If PECs or sign (for a hearing child) are being used, it should be for a brief time as a long term system is evaluated. These systems do not provide auditory feedback and are not universally understood.
Kate Ahern wrote about this and you can link to her blog here. If a professional tells you that your child has to climb a hierarchy and prove that he can use a high tech device, find a new professional.
Motor skills myth: “They need bigger buttons (less language) because their motor skills are too poor for little buttons.”
Is the individual able to purposefully move his/her hand? Is he able to access his mom’s iPhone to get into YouTube?
Use a key guard and/or limit vocabulary on the screen initially to allow for more accurate “hits.” Fine motor skills frequently improve with use of AAC as the child’s language grows. Frequently, key guards improve accuracy more successfully than increasing the button size. This is especially true if the individual is having difficulty with finger isolation. Fingers dragging in the screen will access larger buttons just as readily as the smaller ones. If someone evaluates your child and says he can only access large buttons, ask if a key guard was trialed.
If the individual has severe physical impairments that make them unable to move purposefully, contact device companies that offer eye gaze technology. This technology allows cameras to read individuals eye movements and speak the words that they look at for a certain amount if time. Physical limitations can be challenging and require additional expertise and/or equipment, but they are not a reason to deny access to a comprehensive communication system.
Age Myth: “He/She has to be a certain age before we introduce AAC.” Or, “Wait until kindergarten (2nd grade, middle school, high school…) and then we’ll take a look at AAC.”
Are other people able to say words and use language at this age? If your answer is yes, then the individual is a candidate for AAC. If your baby is at risk for speech or language delays or there is any indication that speech may be delayed/difficult for this baby (I.e. No cooing or babbling, diagnosis, surgeries, traumatic or premature birth…), start modeling as soon as you’re concerned. Keep in mind that babies are immersed in language immediately, but it takes them two years to start putting words together.
Whether you are concerned or not, play and talk to your baby. Narrate your actions: explain what you’re doing and why. Respond when he/she vocalizes. Cherish his/her words and enjoy the beautiful phenomenon of language development that so many take for granted.
Monitor speech milestones. If your baby regresses or begins missing milestones, don’t “wait and see”… Introduce AAC as soon as you notice your child’s frustration or regression. AAC use will support – NOT inhibit- verbal speech development.
Enough Verbal Speech Myth: “He/She has enough verbal speech and can say sentences so the individual doesn’t need AAC.”
This one isn’t on the flow chart because, well, the flow chart was getting a little crowded.
Individuals with verbal speech may also be AAC candidates. If a child is only able to say the same scripted, limited sentences (“I want a cookie please.” “I want computer please.” “I watch Sponge Bob.”), he/she may be having difficulty segmenting where one word starts and another ends. In essence, he may be handling each of those sentences like one big, long word. The benefit of being able to segment words is that they can then be re-combined to form novel utterances.
Some individuals who express themselves very well verbally may have times (I.e. following seizures or when they’re exhausted or sick) when they are not able to speak verbally. AAC is appropriate and beneficial for these individuals to allow them to have a voice when they are at their most vulnerable.
Symbol representation myth: “He/She has to understand symbol representation before we can introduce AAC.”
This is also not on the flow chart, but it’s worth mentioning. Symbols are abstract to everyone. We learn their meaning through exposure and experience. If you want a child to have symbol representation, use AAC. If she loves to play ball and every time she touches the ball and the device says “ball” and someone throws a ball to her, she’ll start to understand the representation of that symbol and use it functionally.
The bottom line is: Individuals are candidates for high-tech AAC if they are not able to express wants, needs, ideas, thoughts, questions, fears, and pain to whoever they want, whenever they want.
High tech, comprehensive AAC provides the means to: express cognition, replace behaviors with appropriate communication, and initiate conversations about self-selected (and sometimes surprising!) topics – which then leads to an increased interest in true, meaningful communication. There is no age requirement to start modeling and immersing a child in AAC. AAC WILL NOT HINDER A CHILD’S VERBAL SPEECH. The consistent auditory feedback provides a model and reduced pressure frequently improve verbal speech skills. Often, a “side effect” of AAC use is the improvement of fine motor skills and attention, driven by the motivation to communicate.
Communication is a basic human right, and there is no pre-requisite skill that justifies delaying access to that right. On the contrary, communication IS the pre-requisite skill to academic, social, and behavioral success.
