Are Women Born Like This? (with video)
This video may leave you wondering if some parts of personality are set very early indeed.
Well, wonder no more.
Science has actually already looked into the matter, and found a significant correlation between fetal testosterone levels and vocabulary, suggesting that fetal testosterone might be involved in shaping the neural mechanisms underlying communicative development.
That is: the LOWER your testosterone, the greater your vocabulary.
One study found that girls had a significantly larger vocabulary than boys at the ages of 18 and 24 months after birth. Their discovery replicated previous findings of a female advantage in language ability, but revealed this sex difference at the earliest point of development.
