Cognitive Disabilities
Plain language, structure, and reduced cognitive load
Cognitive disabilities include a wide spectrum of conditions affecting memory, attention, problem-solving, and comprehension. Designing for cognitive accessibility benefits all users - not just those with diagnosed conditions.
Clear structure
- Use headings to divide content into scannable sections
- Put the most important information first
- Keep paragraphs short - one idea per paragraph
- Use lists for steps, options, and grouped items
Plain language
- Aim for a 6th-8th grade reading level for public-facing content
- Use common words: "use" not "utilize", "show" not "demonstrate"
- Use active voice: "Submit your application" not "Applications must be submitted"
- Keep sentences short - one idea per sentence
Consistency
- Use the same term for the same thing throughout - don't call something a "Contact Form" on one page and "Get in Touch" on another
- Keep navigation in the same location on every page
- Make interactive elements look and behave predictably
Error handling
- Identify errors clearly and specifically: not "Invalid input" but "Please enter a phone number with area code"
- Do not clear form fields on error
- Allow users to review and correct errors before submitting
All of these improvements benefit users broadly. Plain language improves comprehension for non-native speakers. Clear error messages reduce frustration for everyone. Structure helps sighted users scan pages faster.
