If you like to sign your name with a flourish, chances are you love being the centre of attention - and you might even be a little vain.
That's according to a study by psychologists, who have discovered that a person's signature can reveal a surprising amount about their personality.
The scientists found that men and women with a large signature are more likely to enjoy being the centre of attention - scoring highly on "sociable dominance" in personality tests.
The study also showed that women with a large signature were more likely to be vain and egotistical than those who had a small signature - though this didn't apply to men.
Sociable dominance is characterised by a positive attitude towards others, a central position in groups, a strong need to dominate and the holding of solid self-esteem.
