Quizplus · Accepted Answer

In the study by Mack and Rock (1998) on inattentional blindness, a significant portion of participants failed to notice a critical stimulus (an unexpected object) that appeared in the visual display while they were focused on judging the length of the arms of a cross. This phenomenon illustrates how attention can be so focused that obvious objects in one's visual field can go unnoticed.
