Question

“What ! You too?I thought I was the only one.”Have you ever said this to someone? If so, you may have ended up becoming friends with this person.

It seemed that similarity often helps form friendships. The Greek philosopher(哲學家) Aristotle once said, “Some define(下定義) friendship as a matter of similarity. They say that we love those who are like ourselves.”

Now , there is some science behind this idea. Scientists from University of California said friends have similar brains, Scientific American reported.

The scientists invited 42 university students to take part in an experiment. Each student watched the same set of videos, which included a comedy, a discussion and a soccer match. Meanwhile, scientists studied their brains and recorded their brain activity.

According to their study, friends who watched the same video clips reacted in similar ways. Similar parts of their brains lit up while watching the videos, especially parts that were connected with motivation(動力)， learning and memory.

However, people who weren’t friends had different reactions to the same clips.

“Having close friends whose brains react like ours may be rewarding because it makes one’s won values, opinions, and interests strength,”scientist Carolyn Parkinson told Business Insider.

But brain similarity is not the only thing that can result in friendship. Scientists from the University of Leipzig, Germany, found that friendship is also based on how physically close you are to someone.

They did an experiment with first-year college students who met in class for the first time. In this experiment, students who sat in neighbouring seats were more likely to become friends.
