The Explanation:
Inattentional blindness, a phenomenon known as "the failure to notice an unexpected stimulus that is in one’s field of vision when other attention-demanding tasks are being performed." This phenomenon is classified as a psychological attentional error - and you'll be relieved to know - not the result of visionary deficits. The main reason for this lack of attention is the overload of stimuli surrounding us; in order to be able to focus on the intended things, we learn to disregard many others and be unaware of the unattended stimuli. There have been a large number of experiments demonstrating that this phenomenon has a significant effect on people’s perception...and now this one with you.
