Studies show that the primacy effect is an important part of first impressions. The primacy effect is the idea that the first impression is very difficult to change. After the first meeting, two people may ________ again and learn more about each other, but the early impressions they formed will __________ their feelings about each other in the future. For example, if a person has a good first impression of someone, he or she probably will not notice bad things about the person later. However, if that person has a bad first impression, he or she will probably notice mostly bad things in the future.
