Answer:
Cocktail party effect
Step-by-step explanation:
In psychology, the term cocktail party effect refers to the phenomenon by which the brain can focus its attention on a particular stimulus while filtering out the other stimuli that are not relevant to it. This phenomenon happens specially during loud parties where the listener is able to focus his/her attention in one particular stimulus.
In this example Romina is at a large party (which is loud) and she suddenly hears her name spoken from the other side of the room. We can see that despite the noise going on, she was able to detect her name being spoken in a loud situation. Therefore, this would be an example of the cocktail party effect.
