"Girls are much quicker than boys at learning how to speak" 

 Girls are quicker at learning to speak than boys, a study
 released yesterday shows. 

 Dr Galsworthy, who presented the findings of his work
 at the first day of the International Conference of Infant
 Studies in Brighton, East Sussex, said he and his
 colleagues used more than 2,000 same-sex and
 opposite-sex twins to explore gender differences in
 cognitive ability between the ages of two an four. 

 He said: "Using twin studies allows researchers to gauge
 the amount of genetic influence on any given trait." 
 Identical and non-identical twins, including non-identical
 opposite-sex twins, were used to see how genetics
 affected both verbal and non-verbal learning. 

 Dr Galsworthy said: "The findings show that as early as
 two years old, girls out-perform boys on cognitive
 scores, particularly in verbal ability. As the twins get
 older, through years three and four, this difference in
 verbal ability becomes smaller."
