Cognitive Disabilities

Plain language, structure, and reduced cognitive load

Users

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.
