He might have benefited from that more than you realize:
A new study shows that first-born children tend to be smarter than their siblings and second-born children are more likely to cause trouble. The University of Edinburgh study reported that the oldest child tends to have a higher IQ and thinking skills than their younger siblings.
A University of Edinburgh study shows first-born children have higher IQs and better thinking skills than their siblings. The study says that shows first-born kids get more mental stimulation than their brothers and sisters.
After examining 20,000 people, researchers from the University of Leipzig concluded that older siblings are smarter on average while younger siblings are healthier and are more likely to be gay (if they're men). It was the second-largest study to look at the effects of birth order.
First-born children's thinking skills outperform their siblings because they receive more mental stimulation from their parents in their early years, research suggests. First borns score higher than their siblings in IQ tests as early as age one, the study has found.
First-born kids tend to be leaders, like CEOS and founders, and are more likely to achieve traditional success. Middle-born children often embody a mix of the traits of older and younger siblings, and they're very relationship-focused.
Researchers have found a correlation between risk-taking and being the last-born sibling.
Younger siblings generally have a lower IQ than their older brothers and sisters, according to three large national surveys from the US, UK, and Germany.
According to Adler, the first born is more susceptible to depression because of high expectations of parents and suddenly losing the attention due to another sibling being born.
You've probably heard it before and brushed it off if you're a second, third or fourth+ child - but it's true: the eldest sibling is the smartest, according to research. And there's not just one reason for it.
The survey concluded that parents tend to favour their youngest child over the elder.
The last born child is often described as sociable, charming, loving, and open, but also as temperamental, irresponsible, and self-centered. Birth order has a significant influence on our behavior in adulthood.
Firstborns are smarter: The verbal ability of first-borns is about one-tenth of a SD higher than for children in the middle of the birth order. There is no evidence that last-borns fare better than intermediate children.
Survey Finds That Youngest Siblings Are the Favorite Child for Most Parents. You will often hear parents say that they love all their children equally but a new study suggests that's a bunch of baloney. In fact, many parents secretly favor their youngest kid over the rest.
While the youngest sibling is usually the funniest kid, mom and dad favor the youngest for a reason that might surprise you. According to a new study conducted by Brigham Young University's School of Family Life, the youngest sibling of the family tends to be mom and dad's favorite child because of perception.
A growing collection of studies suggests that being the youngest sibling may come along with some major health advantages. Researchers have found that the baby of the family is often slimmer and less prone to illness. As a result, younger siblings can expect to live longer than their older brothers and sisters.
Younger siblings may be especially vulnerable to trauma because they are in an earlier developmental stage than the rest of the family. While older siblings and parents will be much more equipped to cope with the stress, the youngest child may feel left behind or not understand how to handle their emotions.
Many previous studies looked into this relationship. There is evidence that the first born children experience more stress than their younger siblings.
Researchers at the University of Illinois used a sample of 377,000 schoolchildren and found there were differences in personality traits, with the eldest sibling tending to be more extroverted, agreeable and conscientious.
Middleborns are just as smart as their siblings.
But a study by the University of Illinois published earlier this year found that firstborns' IQs are only one point higher, on average, than their younger siblings — a fairly negligible difference.
A gifted child's IQ will fall within these ranges: Mildly gifted: 115 to 130. Moderately gifted: 130 to 145. Highly gifted: 145 to 160.
But genetics can explain the wide range of possible IQs too because so many different genes are involved in developing and running a brain. It is possible, for example, to inherit all the higher IQ genes from each parent and leave the lower IQ ones behind. Now the child will be brighter than the parent.
Oldest Child Birth Order Traits (Firstborn)
“Firstborn children can be goal-oriented, outspoken, stubborn, independent, and perfectionistic,” Smelser says, and when you look at the way firstborns are nurtured, it starts to make sense why.
They shoulder less responsibility, so the youngest child tends to be carefree, easygoing, fun-loving, affectionate, and sociable, and they like to make people laugh. But being the youngest isn't all roses.
Successful in journalism, advertising, sales and the arts, famous youngest children include Cameron Diaz, Jim Carrey, Drew Carey, Rosie O'Donnell, Eddie Murphy and Billy Crystal. Only Children: Only children have similar characteristics to firstborns and are frequently burdened with high parental expectations.
