Communication is a fundamental human need. It allows us to express thoughts, emotions, and desires, fostering relationships and a sense of belonging. However, communication can take different forms for individuals with neurobiological challenges, as many rely on alternative methods, such as sign language or augmentative communication devices, to produce functional language.
The Interpersonal Whole-Brain Model of Care® (IWBMC™) acknowledges that communication extends beyond speech. Individuals can develop reliable and functional language skills by integrating alternative methods such as sign language, picture-based systems, or assistive technology. These alternative communication methods do not replace vocal speech but serve as a bridge, supporting language development and providing individuals with the tools necessary to engage meaningfully with the world around them.
The Importance of Augmentative Communication
For many non- or minimally vocal individuals, the inability to communicate effectively can lead to significant challenges. Difficulty expressing needs and emotions may result in frustration, which can manifest as behavioral concerns, withdrawal, or social isolation.
Providing individuals with alternative communication methods helps mitigate these challenges by:
- Enhancing self-expression – Allowing individuals to convey their needs, thoughts, and emotions.
- Reducing frustration – Minimizing frustration-related behaviors by offering a clear means of communication.
- Encouraging independence – Enabling individuals to navigate daily interactions with greater autonomy.
- Supporting social engagement – Facilitating meaningful interactions with family and peers.
Types of Augmentative Communication
Multiple communication modalities are available, each tailored to an individual’s unique strengths and challenges. Some of the most used methods include:
1. Sign Language
Sign language provides a visual form of communication through hand and facial movements. While American Sign Language (ASL) is widely used, individuals with fine motor challenges may require modified signs. A key consideration is that not all communication partners are familiar with sign language, which can impact its generalization in different settings.
2. Low-Tech Picture Exchange
Printed symbols or picture-based systems enable individuals to communicate by pointing to or exchanging images that represent words, phrases, or concepts. This method can be tailored to an individual’s vocabulary and effectively introduce alternative communication.
3. High-Tech Picture Exchange
High-tech devices enable individuals to select words, phrases, or symbols that are then vocalized by the device. These devices offer extensive customization, allowing for expanded vocabulary and sentence formation. Eye-gaze technology, in particular, provides communication access for individuals with limited motor control, allowing them to navigate the device using only their eyes.
4. Typing-Based Communication
For some individuals, digital or physical keyboards provide a method for typing words or sentences. Many device applications also include text-to-speech functionality, further enhancing accessibility. This method is highly effective for individuals who can spell and structure sentences but require support in vocal output.
Moving Toward Independent Communication
The ultimate goal of assisted communication is to promote independence and enhance an individual’s ability to interact with the world. While initial support is often required to establish proficiency with alternative communication methods, ongoing assessment ensures that individuals continue to progress toward independent, functional communication.
