Most of us tend to think that with older siblings a baby will grow up with a friend or protector to watch over him or her and to guide the younger sibling through the "growing up years" in life. While that may very well be the case in many situations, according to Science Daily, there have already been several research studies conducted which prove that children who have an older sibling actually have significantly less skilled language development and linguistic performance than children who do not have an older sibling.
A brand new research team has shed light on a more specific result of this study - focusing on children who have one or more big brothers.
As incredible as it might seem, a research team from the CNRS, the AP-HP, the EHESS, the ENS and INSERM have have shown, that indeed, children who have grown up in a home with an older sister have the same language development to children who have grown up in an environment with no older sibling.
On the other hand, only children who have older brothers were found to have affected the language skills portion of the study. The research included more than 1000 children and followed them from birth to five and a half years old. The childrens' language skills were tested at the ages of 2, 3, and 5 and a half years old by measuring their vocabulary levels, syntax and reasoning.
It was discovered that children in the study who have an older brother had, on average, a two-month delay in language development compared to children with an older sister.
In order to explain this bizarre result, the scientists involved in this study offer up two theories. The first is that older sisters might be more willing to talk to their younger siblings than older brothers are and may be more willing to compensate when their parents are less available. The second theory is that older sisters may feel the need to compete less than older bothers for parental attention, allowing the younger child to soak up more of their parents' time.
