Cognitive Usability

The extent to which a system, interface, or information resource can be effectively used by people with varying cognitive abilities and processing styles. Cognitive usability goes beyond traditional usability measures (efficiency, effectiveness, satisfaction) to specifically consider how well a design supports cognitive processes such as comprehension, memory, attention, problem-solving, and decision-making. It is particularly relevant for users with cognitive disabilities, older adults, and anyone in contexts where cognitive resources are limited (such as multitasking or stressful situations).
