AAC Myths

There are many myths surrounding AAC. Here we offer a more in-depth look at some of those myths and why they are not true. 

Will AAC keep an individual from talking?

No. In fact there is a decade of research that states AAC does not keep an individual from using or developing natural speech. Millar, Light & Schlosser (2006) reviewed previously published studies that, among other criteria, presented data on “speech production before, during and after AAC intervention.”

This review revealed that participants demonstrated the following with the introduction of AAC:

  • Increases in speech production—89%
  • No change in speech production—11%
  • Decreases in speech production—0%

But why? Think about it this way, we all use multiple forms of communication everyday (talk, point, facial expression, body language, etc.). AAC is no different; it can co-exist with other forms of communication as well. Research (Blischak, Lombardino, & Dyson, 2003; Hux et al., 2006) shows that AAC has a positive effect on speech because:

  • AAC increases and improves an individual’s participation in conversation with the ability to produce longer messages
  • AAC reduces physical demands and the pressure to speak
  • The immediate production of speech provides a model for the individual as well as an association between the word and the symbol
  • AAC can be used as a tool to cue word recall for older adults in conversation.

Can a child be too young to use AAC?

No. You can never be too young to enhance communication. AAC positively impacts language development, cognition, and literacy skills as well as participation in social, educational, and play environments which are all crucial to young children. AAC gives children with communication challenges the potential to expand skills necessary for productive lives. It will not negatively impact their development and can, in fact, enhance development of cognitive skills and play.

Is AAC useful for an individual who has some speech?

Yes. AAC provides the support necessary to help an individual with speech disabilities reach their full potential when conversing independently with both familiar and unfamiliar communication partners. AAC can be used in addition to their current expressive abilities while promoting relationship growth with others, independence, increased vocabulary, and deeper conversations. Additionally, AAC will help the individual develop language and literacy skills. While the ability to say a few words is great, it is not enough to communicate effectively with an unfamiliar communication partner.

What if an individual has a physical disability and is unable to touch a device?

A solution exists. There are a variety of ways that someone in this situation can make selections on an AAC device. This is often referred to as the selection method. Individuals who are not able to touch the device can use eye tracking or switch scanning as their primary mode of selection. 

Eye tracking technology makes it possible for a computer to precisely select where a person is looking. When eye tracking technology is combined with a speech generating device, communication becomes possible for people who have both speech and motor impairments.

Switch scanning makes it possible to control a switch with specific body parts. Buttons will appear on a device's screen from left to right. When the button of a person's choice is highlighted, they can select it by clicking the switch with a specific body part.

We compiled a list of some of the most frequently asked questions when it comes to AAC.  

Where do I begin?

This simple Screening Questionnaire  can help you find out if an individual would benefit from AAC.A Speech-Language Pathologist (SLP) should perform a formal evaluation to determine if an AAC device is appropriate. The evaluation will assess and compare different devices to determine which one will allow you to achieve the highest level of communication success. Most school districts and private speech and language clinics either employ SLPs or can refer you to a qualified SLP in your area. The Tobii Dynavox consultant in your area can help you take the first step!

Can AAC help support positive behavior?

Behavior is a form of communication. A person’s behavior typically reflects their feelings toward a situation. People with communication difficulties often feel frustration in settings where they are unable to express themselves. Therefore, being able to effectively communicate with AAC can only enhance positive behavior. AAC offers individuals a way to express their feelings, needs and desires as well as connect with others, which can positively impact behavior.

Sometimes additional supports are needed to encourage positive communication. Visual supports such as visual schedules and communication boards are likely to decrease challenging behaviors in children (Johnston, Nelson, & Palazolo, 2003). These researchers used an AAC intervention with preschoolers. They found that with the use of symbols, children not only decreased their off-task behaviors, but also showed significant increases in initiating play.

How can I make AAC a successful experience?

You can help by creating a positive communication environment in the following ways:

Modeling is also a good way to encourage use of an AAC system. In order for someone to learn how to use a communication aid, it must be consistently demonstrated to them in the expected manner. Just like good speech is developed in children by modeling it when we talk, proper use of AAC must be demonstrated as well. To model using AAC, speak while simultaneously pressing the buttons on the AAC device to provide the person you are caring for with a multimodal means of learning language.
