Is it true that left-handed people are smarter than right-handed people? Chris McManus, professor of psychology and medical education at University College London, responds;
“If by intelligent you mean someone who performs better on IQ tests, the simply answer is no.  Studies in the U.K., U. S. and Australia have revealed that left-handed people differ from right-handers by only one IQ point, which is not noteworthy.”
Left-handedness is, however, much more common among individuals with severe learning difficulties. A slightly higher proportion of left-handers have a stutter(口吃). Other problems, such as a higher rate of accidents reported in left-handers, mostly result from a world designed for the convenience of right-handers, with many tools not made for the left-handed.
However, if by smarter you mean more talented in certain areas, left-handers may have an advantage. Left-handers’ brains are structured differently from right-handers’ in ways that can allow them to process language, relations and emotions in more diverse and creative ways. Also, a slightly larger number of left-handers than right-handers are especially gifted in music and maths. A study of musicians in professional orchestras(管弦乐队)found a greater proportion of talented left-handers, even among those who played instruments that seem designed for right-handers, such as violins. Similarly, studies of adolescents who took tests to assess mathematical ability found many more left-handers in the population. The fact that mathematicians are often musical may not be a coincidence.
For other talents and skills, the benefits of being left-handed are less clear. In one-on-one competitive sports, being in the minority can be an advantage. For example, most right-handed tennis players have little experience of playing left-handers, but left-handers have plenty of experience of playing right-handers.
Whatever the advantages are, handedness seems to be genetic. With 10 percent of people preferring their left hand, there must be some selective advantages, or else the genes would probably not survive.
The underlined word, “noteworthy”, in the second paragraph, probably means“_______”.

A.remarkable B.convincing
C.helpful D.beneficial
