STATES CHRONICLE – A new study has attested the idea that oldest siblings from the same parents may be smarter. Scientists believe that first-born kids are smarter than their younger siblings. Specialists from the University of Edinburgh have developed this new research. The explanation which lies at the foundation of this idea is that first-born children usually receive more mental motivation from their parents during their first years of life.
On February 9, experts from the University of Edinburgh noted that researchers discovered that parents tend to change their attitude as newborns are welcomed into the family. As the family gets bigger and bigger, parents change their behavior towards their children. They may offer younger siblings less mental motivation, participating in fewer activities than they did with their first-born children.
Parents tend to take part less frequently in activities like reading with the kid, playing different games, or even playing musical instruments. They will no longer be so eager to do crafts and puzzle with them. Studies have shown that oldest siblings in a family tend to obtain higher scores on an IQ test compared to his/her sibling, even if researchers were to compare their results when testing them at the age of 1.
Experts claimed that these findings might explain the birth order effect. This indicates that children who are born first in families were later successful people, reporting higher education levels and better wages.
Economists from the University of Sydney, the University of Edinburgh and the Analysis Group have collaborated for this study. They had analyzed data provided by the US Bureau of Labor Statistics. Approximately five thousand children were monitored before they were even born until the age of 14. Every two years, these children were assessed, performing different types of tests which proved to be helpful in developing the study.
Specialists had also considered various factors like the background and economic condition of the family. Even if parents seemed to offer their children the same emotional support, they did not receive the same mental stimulation.
Among all those tests, specialists included picturing vocabulary assessments, reading single words and doing reading recognition where they were bound to match letter and name characters’ names. According to the results of the study, first-born children’s advantages began when they were born to three years of age.
