How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to change blindness is inattentional blindness.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Cognitive psychology

The failure to notice large visual changes masked by a disruption

Ronald A. Rensink, J. Kevin O'Regan, and James J. Clark introduced the term change blindness in 1997 to name a striking failure of visual perception: when a brief blank field, flicker, or other disruption is placed between an original scene and a modified version, observers often cannot spot even large, repeated changes to what they are looking at. Daniel Simons and Daniel Levin extended the finding to the real world in 1998, showing that people conversing with a stranger frequently failed to notice when that stranger was quietly swapped for a different person during a brief interruption. The effect turns on a disruption that hides the local motion signal a change would normally produce, so that without focused attention on the changing object the change goes undetected. What makes change blindness a landmark is its evidence that people do not hold a complete, detailed internal picture of a scene from moment to moment, and that attention, rather than raw visibility, governs which changes are perceived.[1][2]

Unit
A measured failure rate: the proportion of changes observers do not detect, or the time and alternation cycles needed to detect them
Recovery means
Not applicable
Measured by
Assessed with flicker, mudsplash, gradual-change, and forced-choice paradigms that record detection rates, response times, or the number of cycles needed to notice the change
