It’s been claimed that playing a musical instrument makes you smarter． New research suggests that regularly playing a musical instrument changes the shape and power of the brain, and may be used in therapy (疗法) to improve cognitive (认知) skills． Experts say there is growing evidence that musicians have brains that are structurally and functionally different from those of non-musicians, especially in the areas of the brain used in processing (处理信息) The parts of the brain that control motor skills, the storage of audio information, hearing and memory become larger and more active when a person learns how to play an instrument and can apparently improve the alertness (警觉) and planning． Lutz Jancke, a psychologist at the University of Zurich, said, “Leaning to play a musical instrument has great benefits and can increase IQ by seven points in both children and adults．We found that even people over the age of 65, after four or five months of playing an instrument for an hour a week, had strong changes in the brain.” The parts of the brain that control hearing and memory, and the part that controls the hands, among others, all become more active. “Of course music isn’t the only answer, but I do believe that it should be used in addition to other things.” Mr．Jancke also said that learning a musical instrument could also make it easier to learn foreign languages and make one more sensitive to understanding the emotions of others．“So not on ly does this make it easier to pick up other languages and have a better memory of one’s own, we have also seen musicians are able to pick out exactly what others are feeling just by the tones of their voices—sympathy, disappointment, that kind of things.” He added, “Several studies indeed show that playing music increases memory and language skills, but more research is needed.” 1．What is the passage mainly about?
