Change Blindness
Definition
Change blindness is a surprising perceptual phenomenon that occurs when a change in visual stimulus goes unnoticed by the observer.
Analogy
Think about watching one of those "spot the difference" games where two pictures look identical but have subtle differences. Sometimes, it takes us ages to spot these changes because our brain doesn't immediately register them - this is similar to change blindness!
