Using social media（社交媒体）to post photos is pretty new. Facebook did not start until 2004. Instagram started in 2010. It was not until 2013 that the Oxford English language dictionary added the term“selfie”. The meaning of“selfie is“a photograph that one has taken of oneself.”

Why do people take“selfies”? Researchers at Syracuse University in New York tried to answer that question. They came up with some surprising answers.

People who post selfies and use editing softwares to make themselves look better show behaviors connected to narcissism（自恋）, the Syracuse researchers said. Narcissists are people who think very highly of themselves, especially how they look.

Ji Won Kim, who worked on the study, said social media can be superficial. By superficial, she means social media is mostly used by people to share unimportant information about their lives -not deeply personal issues.

_____________. People who post group selfies show a need for popularity and a need to belong to a group, the Syracuse University research found.

Other findings from the study include: There are no main differences on how often men  and women post selfies and how often they use editing softwares like Meitu. But men who post selfies show more of a need than women who post selfies.

Another researcher Makana Chock also worked on the study. She said selfies should not be   seen as completely negative. She said some people feel “peer pressure”（同伴压力）to post selfies. And some follow the popular belief that if there is no picture of an event or experience, it did not really happen.
