"A photograph that one has taken of oneself,typically with a smart phone or webcam and uploaded to a social media website."This is the definition（定义）of the word "selfie" in the Oxford English fact,it wasn't even in the dictionary until August, earned its place there because people are now so obsessed（着迷）with selfies—we take them when we try on a new hat,play with our pets or when we meet a friend whom we haven't seen in a while.
But does this obsession actually make sense?Is there any scientific explanation for it?Well,you should probably ask James Kilner,a neuroscientist at University College London.
Through our lifetime we become experts at recognizing and interpreting other people's faces and facial contrast,according to Kilner,we have a very poor understanding of our own faces since we have little experience of looking at them—we just feel them most of the time.
This has been proved in previous studies in which participants were shown images of themselves and asked to match their facial expressions in the most cases,they failed to accurately produce the same facial expressions without being able to see themselves in the mirror,according to BBC.
To further test how we actually sense our own faces,Kilner carried out another showed people different versions（版本）of their own image—the original which had been edited to look less attractive and one that was made more attractive—and asked them to pick the version which they thought looked most like er found that most people chose the more attractive suggests that we tend to think of ourselves as better-looking than we actually are.
But what does it say about selfies?Well,isn't that obvious?Selfies give us the power to create a photograph—by taking it from various angles,with different poses,using filters（滤镜）and so on—that better matches our expectations with our actual faces.
"You suddenly have control in a way that you don't have in non-virtual（非虚拟的）interactions,"Kilner told the Canada-based CTA ies allow you "to keep taking pictures until you manage to take one you're happy with", he explained.
