Sleep habits. A newborn who doesn’t sleep or a pre-schooler who always resists bedtime? Intelligent kids are often poor sleepers, says the research, their little brains are so stimulated that they find it challenging to get to sleep.
Misconceptions. Often parents wonder if the size of their baby’s head is an indicator of a disability. But say scientists, it is more commonly simply the result of genetics with mom or dad having a particularly large head themselves.
Surprising research. A larger than average size head (with the average size of a baby’s head in U.S. varying between 13.5 to 14 inches) is rarely a sign that your child has a learning disorder or disability and of course, according to the new research from the University of Edinburgh, might even mean they are more intelligent.
What researchers asked. Researchers from the university, led by Professor Ian Deary, were trying to piece together the connection between someone’s health, their IQ and their genetics. Does intelligence have any roots in genes, or is it random?
Obtaining samples. To carry through with the study, personal information from over 100,000 people were thoroughly sifted through. After some basic tests that included blood, urine and saliva samples, researchers learned more about head sizes than they probably anticipated prior to the study.
Nature versus nurture. Of course, a multitude of other factors come into play when determining a child's success later in life. Upbringing and family life have a huge influence on a developing child.
Settling the debate. The results of the study heavily favor "nature" in the nature versus nurture debate, due to the genetic influence on cranial circumference. The study therefore suggests a correlation, but the data is not definitive, nor has it been proven beyond being a hypothesis.
