Rosa judges everything serena does based on the fact that serena is an only child. rosa is engaging in which attribution error?

I believe the answer is: overattribution

overattribution refers to a social occurence when people believe they could freely express everything that they  want and assumes it's true and other people would believe it. This occurence considered to be a form of bias, and make people constantly give false characteristic toward others without having enough evidence.
