Children of the Lysha and the children who own equally with both hands, they manage to school worse than right-handedness. Moreover, lushas are even worse than the boys of the left-handed manner. Such data, as the website Inopressa.ru publishes The Independent with reference to the study of Gregg Professors, Carola Propper and Katarina Yankke. Data is based on national British statistics on school performance.
According to the study, in total there are about 10% of the left-handed children and approximately 7.5% of children who have equally both hands. At the age of 8, 11, and 14 years old, the girls of Levsha, as well as the children of both sexes, who own both hands, lag behind peers. This was shown by the IQ tests. Only among boys is the separation of left -handed people less significant.
During the tests, left -handed people were gaining 1% less than right -handedness. With those who own both hands, the situation is even worse. They are characterized by "slow development, first manifested at the age of 8 years and remaining noticeable at the age of 14, especially in girls," the study says. Among the possible explanations of this "double -burning" is the lack of attention of parents. It is they who should engage in the development of the child.
However, the author of the article notes, there is also good news for the same boys: most geniuses are left -handed. That is, they thus occupy the upper and lower steps in the spectrum of abilities.
Independent also reminds the world of well-known levisha figures. Among them are George Bush Sr., Kurt Cobain, Usama Ben Laden, Mat Gruning (author of Simpsons), Jeanne d'Arc, Angelina Jolie, Jack Ripper. To this list from Independent, you can also add the name Paul McCartney and Bill Gates.
