Carry context
Say why the person is here, what changed and what happens next.
Choose what your brain has room for
Choose how much information your brain has room for right now.
I think from the details up, so this site sometimes carries a lot of context. The information stays intelligent; the amount presented at once changes.
The instructions are part of the intervention
Make instructions and systems easier to understand and use.
Cognitive UX looks at the work a system quietly transfers to the person using it: remembering context, finding hidden steps, interpreting vague language and recovering when capacity changes.
Working principles
Accessibility is not only whether someone can technically reach the information. It is how much unpaid detective work happens first.
Say why the person is here, what changed and what happens next.
Show the materials, timing, transitions, people and decisions hidden inside one step.
Complete theory can wait until after orientation and action.
The same person may need different density, motion and instruction depth at different times.
Experiments on the workbench
Same intelligence. Deliberately rationed according to available capacity.
The current switch changes content density, visual competition, type size and the number of available paths without creating separate URLs.
A sliding capacity scale that changes the guidance beside it: more context when there is room, larger type and one direct instruction when there is not.
A barriers map for locating where access broke down without automatically locating the problem inside the person.
A working proposition
The lab is a place to make that hidden work visible, redesign it and test whether the result remains usable outside ideal conditions.
