Inattentional blindness is a simple lack of attention not associated with any vision defects or deficits.

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

Answer: (B)

Inattentional blindness describes a failure to notice a salient stimulus in your visual field when your attention is focused elsewhere. It’s not due to any vision defect—your eyes can see it, but your brain isn’t processing it because attention is occupied with another task. This differs from change blindness, which is about missing changes in a scene, often when you’re not looking at the right aspect of it. Perception is the broader process of interpreting sensory input, which can be influenced by where your attention is directed. Attention is the broader process of focusing cognitive resources; inattentional blindness is a specific outcome of that focus being elsewhere. So the statement correctly identifies inattentional blindness as a lack of attention not tied to vision problems.
