I’ve been following self-declared “Accessibility Old Timer” Gareth Ford Williams for a while now. The deeper I get into my accessibility journey, the more time I spend thinking about cognitive accessibility. In particular, how we can build digital experiences without barriers for neurodivergent folks like myself and my son. Gareth has put together this helpful guide: A Cognitive perspective on UX Design Principles, which includes a neurodivergent perspective with links to relevant guidance and resources. Recently, the W3C also put out the web version of Making Content Usable for People with Cognitive and Learning Disabilities. Depending on how neurodiversity is defined, between 10 and 30 percent of the population has a neurodivergent trait. Cognitive design principles can lead to better user experiences for all, without leaving so many people behind.
