Women really do talk more than men – 13,000 words a day more

A recent study has found women have higher  levels of Foxp2 protein. The research team from the University of Maryland found male rats – the chattier gender in rodents – make more of the protein than their female counterparts.

Ladies, the next time your being chastised for talking too much, before saying that women don’t talk more you should read on and explain to him at length that its all because of the Foxp2 protein.

It has already been claimed that women speak about 20,000 words a day approximately 13,000 more than the average man. But now scientists have found the key to  explaining why women are more talkative.

A research paper suggests that higher levels of the protein are found in the female brain. US researchers found that those with  more  Foxp2, known as the ‘language protein’, in their brains were more talkative.  Among humans that was women, but in rats its the males. The researchers set out to determine  what might make male rats more vocal than their female cage mates. They  separated four-day-old pups from their mothers and counted the number of times they cried out. Both male and female pups emitted  hundreds of cries, but the males called out twice as often. As a result, when the pups  were put back in the same cage as their mother, she fussed over her sons first.

Researchers found the so-called ‘language protein’ that  makes women more talkative also causes male rats to be more vocal than their  female cage mates. Tests on the parts of the brain known  to be  involved in vocal calls showed the male pups to have up to twice  as much Foxp2 protein as the females. The researchers then ramped up its  production in the brains of female pups and reduced it in males. This  led to the female rats crying out more often and their mothers showing more interest to them. The males in contrast, became less ‘talkative’, the Journal of Neuroscience reports.

Next, the University of Maryland researchers tested samples from ten boys and girls aged  between three  and five. This showed the girls to have 30 per cent more of the Foxp2 protein than the boys, in a brain area key to language in  humans.

Researcher Margaret McCarthy said:  ‘Based on  our observations, we postulate higher levels of Foxp2 in girls and higher levels  of Foxp2 in male rats is an indication that Foxp2  protein levels are associated  with the more communicative sex.’

Studies have shown that the women like to talk from an early age. Girls learn to speak earlier and more quickly than boys. They produce their first words and sentences earlier, have larger vocabularies and use a greater variety of sentence types than boys of the same age. However, Simon Fisher, one of the  Oxford  team who first pinpointed the protein, cautioned against drawing big conclusions from a study of such a small number of children.
