change_blindness
The failure to notice significant changes in a visual scene when the change coincides with a visual disruption such as a blink, saccade, or scene cut. Even large, obvious changes can go completely undetected if they occur during a brief interruption in visual continuity. This reveals that our perception of a stable, detailed visual world is largely an illusion.
In a famous experiment, a person asking for directions is briefly replaced by a completely different person behind a passing door, and approximately half of participants fail to notice the switch, continuing the conversation with a stranger.
In a usability test, a website's 'Buy Now' button changes color and moves to a different corner of the screen between two page loads, yet the majority of test participants continue clicking where the old button was, never noticing it has shifted.
During a film scene where two characters talk over dinner, the wine glass in the background alternates between full and empty across different camera cuts, yet audiences watching the scene rarely detect the inconsistency.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Were significant changes in the environment missed during a transition?
Type: binaryDid a disruption (interruption, page change) coincide with the unnoticed change?
Type: binaryWould the change have been noticed with continuous uninterrupted observation?

Visual perception does not maintain a detailed internal model of the scene. Instead, the brain creates a sparse representation and relies on the external world as its own memory. When disruptions break visual continuity, changes in unattended areas go unrepresented.
In safety-critical contexts, use systematic scanning procedures rather than relying on noticing changes. Implement change-detection aids and checklists in domains where detecting changes is important.
Change blindness is critical in driving safety, aviation monitoring, medical imaging (radiologists missing changes between scans), and security screening. It is exploited by magicians and pickpockets.
Use these tools to detect, analyze, or train this aspect.
