In WebAIM’s article Evaluating Cognitive Web Accessibility, the most varied and complex area of accessibility is addressed. Cognitive accessibility is more prevalent than all physical and sensory disabilities combined, but seems to be dealt with the least, probably because it’s most difficult to pinpoint as well as to solve. Much needed general principles and specific guidelines (referred to as a checklist in article) are provided in the article.
Here are the principles listed for cognitive accessibility:
- Simple
- Consistent
- Clear
- Multi-modal
- Error-tolerant
- Attention-focusing
- Improving web accessibility for this audience will improve access for everyone
The guidelines are categorized under:
- Assistive Technology Compatibility
- Consistency
- Transformability
- Multi-modality
- Focus and Structure
- Readability and Language
- Orientation and Error Prevention/Recovery
