Does your older brother think he’s cleverer than you? Well, he’s probably right. According to a new research published in the journal Intelligence, the oldest children in families are likely to have the highest IQs and the youngest the lowest.
A number of studies have suggested that IQ scores drop with birth order. In the most recent study, at Vrije University, Amsterdam, researchers looked at men and women whose IQ had been tested at the ages of 5, 12, and 18.
The results, which show a trend(趋势)for the oldest to score better than the youngest in each test, involved about 200,000 people. That showed that first-borns had a three-point IQ advantage over the second-born, who was a point ahead of the next in line.
The order of birth can also affect personality, achievement, and career, with first-borns being more academically(学术)successful and more likely to win Nobel prizes. However, eldest children are less likely to be creative. Charles Darwin, for example, was the fifth child of six.
Exactly why there should be such differences is not clear, and there are a number of theories on environmental influences on the child.
The so-called dilution (稀释法) theory suggests that as family resources, both emotional and physical, as well as economic, are limited, it follows that, as a result , as more children come along, the levels of parental attention and encouragement will drop. Another theory is that the intellectual(知识的)environment in the family favors the first-born who has, at least for some time, the benefit of personal care and help.
The theory which enjoys the most support is that the extra time and patience that the earlier-borns get from their parents, compared with those arriving later, gives them an advantage.
