According to this article in The Daily Mail, Baroness Greenfield, a professor of pharmacology at Oxford University, warns that Facebook and Twitter are guilty of creating a generation of narcissistic child-like adults constantly seeking the approval of others.
From the article:
Repeated exposure to social networking sites leaves users with an 'identity crisis', wanting attention in the manner of a toddler saying: 'Look at me, Mummy, I've done this.'
The academic suggested that some Facebook users feel the need to become 'mini celebrities' who are watched and admired by others on a daily basis.
They do things that are 'Facebook worthy' because the only way they can define themselves is by 'people knowing about them'.
'It's almost as if people are living in a world that's not a real world, but a world where what counts is what people think of you or (if they) can click on you,' she said.
'Think of the implications for society if people worry more about what other people think about them than what they think about themselves.'
