Music raises your IQ
E. Glenn Schellenberg, a University of Toronto psychology professor, was skeptical about claims that music makes you smarter when he devised a 2004 study to assess its impact on IQ scores. He randomly assigned 132 first-graders to keyboard, singing or drama lessons, or no lessons at all. He figured that at the end of the school year, both music and drama students would show bumps in IQ scores, just because of “that experience of getting them out of the house.” But something unexpected happened. The IQ scores of the music students increased more than those of the other groups.
Another Canadian study, this one of 48 preschoolers and published in 2011, found that verbal IQ increased after only 20 days of music training. In fact, the increase was five times that of a control group of preschoolers, who were given visual art lessons, says lead researcher Sylvain Moreno, an assistant professor of psychology at the University of Toronto. He found that music training enhanced the children’s “executive function”—that is, their brains’ ability to plan, organize, strategize and solve problems. And he found the effect in 90% of the children, an unusually high rate.
