Perspective
A practical cognitive and usability review
Look for memory, ambiguity, interruption and recovery costs that a technical accessibility scan cannot evaluate.
Cognitive accessibility should not be reduced to a readability score.
Follow a real task
Work through the task while noting what the interface requires the person to understand, remember, infer and recover from.
Look for avoidable memory
Does the person need to retain information from another page or step? Is previously entered information requested again? Are instructions still available when needed?
Look for ambiguity
Are labels, instructions and next steps predictable? Does terminology assume organisational or specialist knowledge?
Look for interruption and timing
What happens when someone pauses, gets interrupted or takes longer? Is progress retained?
Look at recovery
Can mistakes be understood and corrected without starting over or remembering hidden information?
Record evidence, not diagnoses
Describe the observed demand: “the reference number shown on step 1 is required on step 4 and is no longer visible.” Do not infer a person’s diagnosis from difficulty with an interface.
What a pass establishes
You reviewed specific cognitive/usability demands in the tested task.
What it does not establish
An internal review does not substitute for research or testing with people with cognitive and learning disabilities.
Follow the evidence trail
Start with the memory barrier → try the memory Lab → use W3C cognitive accessibility resources for broader guidance beyond conformance.
