Answer:
Selective perception.
Step-by-step explanation:
The ability to focus our attention on certain stimuli while ignoring others is called selective perception. Selective perception is a type of cognitive bias that occurs in the perception process when the person, based on her/his expectations, selects an object of attention and disregards the remaining part of the information. The function of selective perception for the person resides in avoiding an overflow in the cognitive system due to the quantity and diversity of the information the person receives. This shows that selective perception has a double utility, since it filters important information for the subject and also eliminates excessive and unnecessary information for the person who receives it.
