Answer:
blindness
Step-by-step explanation:
The failure to notice something that is completely visible due to a lack of attention is referred to as inattentional blindness.
Inattentional blindness is considered to be the failure of noticing something that is very visible and sudden because the attention was focused on some other tasks.
Scientists have carried out experiments on this phenomenon where participants were asked to look at a screen with different moving objects and had them focus on a certain thing. This explained the validity of this phenomenon.
