Question

Courtney Walker · Accepted Answer

Final Answer : D, Explanation :  This question refers to a famous psychological experiment known as the Invisible Gorilla test, which demonstrates selective attention and inattentional blindness. Participants focusing on the white-shirted players often fail to notice a person in a gorilla suit walking through the scene, illustrating how focusing attention on one task can make us blind to other unexpected events.
