The size of the head shows the IQ

A group of researchers in Britain, including Dr. Catherine generation from the University of Southampton that the intelligence of the child could be reflected in part the extent of the growth of the baby's head in the first year.
She and her colleagues in the generation of a copy of the newspaper in October of Pediatrics that "the weight of the brain that connects to the child at the age of one year could help to determine the extent of intelligence in the future."
It is not known, researchers precisely what makes the heads of some children are bigger than others, and scientists assert that there are many other factors, and including the relationship between fathers and mothers and children, which could affect the intelligence of the child and brain development, especially in early childhood .
During the study team Dr. Jill studied 633 children of Britain, where the researchers using a measuring tape to determine circumference at birth, children's heads, a year later, after four years and eight years later.
The children tested the level of intelligence when they were in fourth and eighth years of age.
It was found that those with larger heads were always getting the highest score in IQ tests, scientists found that the growth of the brain at the stage of the first year is a key factor. The growth is happening after that is less important in the level of intelligence.
The researchers wrote that "the growth of the mind after childhood, does not believe that any offset poor growth occurred in the first year of life."
The researchers also studied the parents of children, where the mothers to complete opinion polls on patterns of maternity who use them, their children and others and other factors such as breastfeeding and depression before pregnancy. The researchers gave each mother-degree based on what was done in the survey.
The children collect higher scores on IQ tests if the level of education of parents is high, and if they were breastfed for three months or more and if the mothers had the highest recorded in their own tests.
Even after adjusting to all these factors, growth remained a child's brain in the first year is linked to the results on tests of intelligence among children in the fourth and fifth years of age.
The researchers said that "our findings provide further evidence that early childhood is the most important stage in the growth stages of the mind at birth."
