Change blindness is a perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it.

• A. Inattentional blindness
• B. Sensation
• C. Perception
• D. Change blindness

Answer: (D)

Change blindness occurs when a visual change in a scene goes unnoticed, highlighting how attention shapes what we perceive. Our eyes constantly scan and build a continuous picture, but small or brief changes can slip by if attention isn’t directed to the changing element or if the change happens during a disruption (like a blink or a flicker). This specific failure to notice a change in the stimulus is what the term describes. Inattentional blindness, while related, refers to missing something visible because attention is focused elsewhere on a different task or object, not necessarily a change in the scene. Sensation is about the initial detection of sensory signals by receptors, whereas perception is about interpreting and giving meaning to those signals. Change blindness uniquely describes the failure to notice alterations in a stimulus rather than missing an object or the basic processes of sensing or interpreting.
