However, a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong.The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old.They were asked to complete several mathematical tasks of different levels.It turned out the left­handers outperformed the others when the tasks involved difficult problem­solving.This pattern was particularly clear in male adolescents.However, when it came to simple arithmetic, there was no difference between left­handers and right­handers.
