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 better 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.

The second year MA (AAC) cohort recently returned to campus for an intensive week of lectures, discussions and supervision sessions as they advanced their mini dissertations. The students immersed themselves in literature reviews, grappled with methodological decisions, screened articles, piloted data extraction processes, and provided one another with support. With such diverse and meaningful topics, the projects promise to generate valuable and insightful findings. We trust the week offered clarity and a strong push forward. We wish every student continued success as they move toward completing their research.

The month of Ramadaan has begun and Muslim people around the world observe a time of fasting, prayer and reflection. The Centre for AAC wishes all those observing this month a blessed and peaceful Ramadaan.

To support inclusive communication, we are sharing a communication board about fasting during Ramadaan. This is a free resource developed by the Centre for AAC. Follow the link: https://www.up.ac.za/centre-for-augmentative-alternative-communication/caac-downloads-resources to download this resource and share it with someone who can benefit from using the communication board.

For families of people who use AAC, rituals and traditions are a time to honour communication in all its forms.

As service providers, we can make these rituals and traditions more accessible by:
- Identifying key vocabulary with family and communication partners
- Adding related vocabulary to AAC systems
- Modelling phrases during shared routines
- Inviting AAC users to express their hopes, reflections and choices

Everyone deserves to participate fully in the traditions that matter to them and their loved ones.

The CAAC recently welcomed the first-year Master’s students in Early Childhood Intervention to their first on-site week (16–20 February). The programme introduced them to the theoretical foundations of early childhood intervention applied to the local context, diving into the multisystem realities faced by young children and their families and the importance of fostering stronger team collaboration. During the week, the students connected with their teammates, who they will collaborate with throughout the two-year program, gaining hands-on experience working in diverse, multi-professional teams.

Our BA Honours in AAC class of 2026 recently attended their first onsite week. Students were introduced to the theoretical concepts related to AAC, severe disabilities, research methodology and AAC assessment. One of the highlights of the week was a collaborative resource-making activity where students worked in groups to develop their own paper-based AAC resources. Creativity, teamwork and practical problem-solving were on full display!

The students appreciated a talk by Ms. Constance Ntuli, Disability Advocate at the Centre for AAC, about how she uses her Speech Assistant AAC app every day. In between the academic sessions, students received information on using the UP library and understanding the principles of academic writing. They also enjoyed getting to know each other as they begin this exciting academic journey together.

On 21 January 2026, Ms Zakiyya Laher successfully defended her doctoral thesis entitled: “The effect of Intensive Interaction on preverbal communication and cortical brain activity in children with profound intellectual and multiple disabilities.”

In her study, Zakiyya evaluated the effect of Intensive Interaction as a responsive socially interactive approach to develop preverbal communication and shared attention in children with profound and multiple intellectual disabilities. The study was complemented by objective measures using functional near-infrared spectroscopy (fNIRS) to examine changes in interaction-related cortical activity during Intensive Interaction.

The results indicate the potential of Intensive Interaction as an approach for supporting preverbal communication in children with profound intellectual and multiple disabilities. Zakiyya completed her doctoral thesis under the supervision of Shakila Dada, Adele May and Nerrolyn Ramstrand (Jönköping University).

We are delighted to celebrate this achievement with Zakiyya and wish her continued success in her academic and research journey.
