Explanation:

Inattentional blindness is a phenomenal that is seen when attention is shifted to a different object or task and observers missing out on an unexpected object, though it may have taken place at the point of fixation. The research study was undertaken to find out on inattentional blindness for complex objects and occurrences in dynamic scenes as most people will miss out on a seemingly obvious, but unexpected occurrence if they are involved in a different monitoring task. Inattentional blindness is reliant on the nature and difficulty of the primary assignment. This indicates that where there is lack of attention, there is no conscious perception.

It was observed that in total, 54% noticed the unexpected event and 46% did not.
