This year the selfie earned its place as the Oxford English Dictionary’s 2013 Word Of The Year．It has taken over our culture-and our smartphones．The rise of the selfie has become universal-between presidents，celebrities(名人)and citizens alike-and the trend is only continuing to grow.

A recent survey conducted by the Pew Internet＆American Life Project found that 54 percent of Internet have posted original photos online．And of those hundreds of millions of photos， many are of selfie photos．

For example，currently there are nearly 62 million posted selfie

photos on Instagram，the social media tool that has significantly contributed to the personal photo’s popularity．That figure，which continues to rise every day, does not even begin to include the selfies shared on Facebook and Twitter.

What makes the selfie so attractive-and why do we feel it a must to take one? According to Dr．Pamela Rutledge，psychologist and director of the Media Psychology Research Center，the desire to take，post and get“likes” on selfies goes back to a biological behavior of all humans．

“ I think it influences our sense of social connection in the same way as it does when you go

to a party and people say‘Oh I love your dress，’” Rutledge told The Huffington Post.“Biological，social recognition is a real need and there is even an area of the brain that contributes to social activity．”

There is a way to adapt to the growing selfie culture．Whether you’re a selfie novice or an advanced poster，there are always things to be mindful of when you’re posting，Rutledge advises.

She offered two main principles to follow when it comes to posting on social media:

1．The Grandmother Rule

“Don't post anything online，whether text or visual，that you don't want grandmother or future

employer to see，” Rutledge said．“Selfies especially．”

2．The Elevator Rule

“You wouldn’t say something in an elevator that you or no one else wants to hear—the whole

world of social media is an elevator，” Rutledge said．“Be aware of the breadth of platform．It's easy to think you’re sharing a photo with a few people，but Instagram is public and people can come across things．”
