A SONATA For Two Can Aid Your IQ
By Nigel Hawkes, Science Editor

0	V	Listening to Mozart can significantly increase your intelligence,
00	the	according to the researchers in America. Unfortunately, the
1		effect is temporary and only lasts about 15 minutes long.
2		Dr Frances Rauscher and two colleagues from the University of
3		California were reported the findings in the journal Nature. They asked
4		36 college students to undergo standard of psychological tests
5		after listening to a tape of Mozart's sonata for the two pianos in D major.
6		They found that the students did better after listening to this music
7		than they did so after hearing a ten-minute tape of instructions
8		designed to make them to relax, or ten minutes of silence. Although
9		the researchers could offer no explanation for the finding, but they
10		said that there had long been a belief that people who are interested
11		in music are tend to perform better at intellectually demanding tasks.
12		They believe that the beneficial effect which depends on the complexity
13		of the music played and they intend to try the other compositions
14		and musical styles to prove the point. They also plan further tests
15		to see if a listening for longer periods produces even greater effects.
