Centre for Augmentative and Alternative Communication

Centre for Augmentative and Alternative Communication We focus on research, education and advocacy in Augmentative and Alternative Communication (AAC) What do we do?

The Centre for AAC at the University of Pretoria aims to provide research and training to improve the lives of persons with severe communication disabilities and their families. The Centre for Augmentative and Alternative Communication was founded in 1990 by Prof Erna Alant in conjunction with Prof Lyle Lloyd from the USA. The impetus to start the Centre came from concerned parents requesting bett

er and more coordinated service delivery for their children with severe disabilities and little or no functional speech. The activities of the Centre quickly expanded from direct service delivery to training and education through degree and non-degree courses. Research was also added to provide evidence-based services appropriate to the South African context, and to mobilise support for persons with little or no functional speech by providing credible evidence of the challenges they face. Today the Centre functions as a postgraduate educational entity at the University of Pretoria, while also maintaining the status of a non-profit organisation, owing to various community projects and commitments. Most of the CAAC main activities are focussed on research, teaching and training is the fields of Augmentative and Alternative Communication and Early Childhood Intervention. The training are conducted in various settings including preschool, primary and secondary levels as well as other institutions and health care settings to support inclusion of children and adults with severe disabilities into the educational, health and employment context. Activities focus on training as well as material and technology development to support inclusion of children and adults with severe communication disabilities into communities. Training

In the over 30 years of the existence of the CAAC, staff has trained over 10 000 persons who use AAC, parents, teachers, and therapists in enhancing communication with individuals with severe disabilities. Follow-up visits to contexts confirmed that the CAAC has reached over eight thousand children, youth, and adults through training of families, community leaders and other professionals. Activities include training in communities as well as five post-graduate programs in the fields of early childhood intervention, severe disabilities and AAC. Leadership and advocacy

The CAAC recently embarked on a national project to assist youth with severe disabilities in getting access to communication and information technology, called the Fofa Project. This project assists young people to "speak for themselves" and facilitate their access to employment. Research

The CAAC staff and students are engaged on an ongoing basis in research in the fields of AAC, severe disabilities and early childhood intervention.

If you work in AAC, you've probably heard the debate regarding core versus fringe vocabulary? Research says both are important to support language development. 👇

✨ Why core vocabulary?
Core words, such as want, go, more, stop, that and they make up 70–80% of everyday language. Although core words are a small set of just a few hundred words, they are generative, meaning one word like "go" can create endless messages such as go home, go outside, go to toilet. This provides huge communicative power from a tiny vocabulary set. 🔑

🎯 But fringe vocabulary still matters.
"Want that" tells you someone wants something but not what it is they want. Fringe vocabulary such as nouns, names, favourite foods and people provide meaning. Without them, communication stays vague.

⚖️ The takeaway from the literature:
Core vocabulary provides the structure while fringe vocabulary provides the content.
Place core vocabulary where it is easy to access as this helps for fast, flexible communication. Remember to place core vocabulary in the same place consistently, so the user knows where to find it. Personalized fringe vocabulary is essential, especially for beginning communicators.

💬 It's not core OR fringe vocabulary. It’s core AND fringe, working together.

In an effort to share our research findings more widely the Centre for AAC regularly shares publications that you can download and read for free.

This is an important part of our work at the Centre for AAC, and there are several reasons why we choose to publish and share our papers openly:

- We want our findings to reach our community. Research has the greatest impact when the people who can use it are able to access it.
- Many of you participate in our studies. Sharing our results openly is one way we honour your contribution and ensure you can see what we learned.
- Clinicians, educators, and families deserve access to current evidence. Sharing evidence means you can use these insights in your daily practice and decision‑making.
- We want to showcase the work of our students. Their research offers valuable insights, and making it freely available promotes learning and future scholarship.

🎓 The Centre for AAC was honoured to host Professor Sarah N. Douglas for the 2026 Neville Cohen Lecture entitled “Communication Partner Training to Facilitate Language and Communication for Children who Require AAC.”

Professor Sarah N. Douglas is an Associate Professor and Director of The RADD (Research in Autism and Developmental Disabilities) lab at Michigan State University. She is currently a Fulbright scholar in South Africa.

The Neville Cohen Lecture is a space dedicated to advancing inclusive communication, disability rights, and evidence based practice. This lecture brings together practitioners, scholars, families, and advocates to reflect on the legacy of Neville Cohen’s work and explore new pathways for supporting people with complex communication needs.

The lecture was deeply appreciated by all who attended. Professor Douglas offered rich, practical insights into communication partner training for partners supporting AAC users. Participants engaged in robust discussions, exploring both solutions and key considerations for communication partner training across diverse contexts.

Happy National Women’s Day, South Africa!

We honour the courage of the women of 1956 who stood up against injustice, and we recognise the women of today who continue to confront inequality and exclusion.

May our commitments be as bold as their footsteps.

Early Childhood Research & Practice Colloquium 2026

Professors Alecia Samuels (Centre for AAC, University of Pretoria) and Gabriel Scheidecker (Department of Social Anthropology and Cultural Studies, University of Zurich) recently co-convened The Transdisciplinary Early Childhood Research and Practice in the Global South Colloquium to engage in high-level critical debate on knowledge systems that drive early childhood development research and practice in African contexts.

Over two days, on 30 and 31 July, invited early childhood development researchers, practitioners, and policy leaders mainly from Africa and the Global South and from various disciplines including anthropology, childhood studies, psychology, early childhood education, social work, public health, and disability studies gathered at the Centre for AAC UP Faculty of Humanities, to rethink how early childhood development is understood, measured, and supported in our contexts. The conversations were rich and challenging.

Here are some key highlights that emerged from the presentations and discussions:
- Transdisciplinary collaboration is essential to gain a fuller picture of families’ and children’s lives and the systems that influence them
- Global models need rethinking
- Early childhood development approaches must be contextually grounded, culturally responsive, and informed by local knowledge systems
- Local definitions of ‘responsive caregiving’ often differ from global metrics, highlighting the need for contextually grounded, culturally aligned understandings of parenting and caregiving
- The importance of recognising diverse caregiving structures beyond the nuclear family
- The importance of challenging Western-centric ECD models
- Rethinking global measurement tools
- Funding and power dynamics matter: There was a strong call for funders to support bottom-up, locally defined solutions.

The way forward is collective. The colloquium closed with commitments to ongoing collaboration, shared research efforts, and collective advocacy. Participants emphasised the importance of Global South researchers leading research in their own contexts so that homegrown evidence and narratives can add to the global ECD discourse.

A word of immense gratitude to everyone who contributed their insights and expertise.

Together, we hope to shape more equitable, context grounded futures for young children and their families.
