Are smart people just naturally attracted to study art or perform music, dance, or drama Or does early education in the art actually cause changes in the brain that develop important components of cognition Recent findings show that there may be some significant causal relationships between arts training and the brain"s ability to learn. The Dana Foundation, an organization with interest in neuroscience, immunology, and arts education, just released a three-year study that found that early training in the arts is possibly good for your brain. Neuroscientists and psychologists at several universities have now enhanced understanding of just how the arts might improve thinking, memory, and language skills. Music education is linked with the ability to control both short-term and long-term memory, geometric representation, and development of reading skills. Dance training improves thinking though mimicry and acting classes seem to expand language. Visual arts lessons outside the classroom in childhood are linked to improved math calculations. In retrospect, I wish I had more art lessons before I took on that advanced math class in high school. It"s not a new idea that the arts can make us smarter. The notion caught fire in the 1990s when researchers showed that college students did better on certain math tests" after listening to a little bit of Mozart. And while the current report from the Dana Foundation did not provide definite theories as to how arts make us smart, what it does is to end the popular notion that people are either right-or left-brain learners. Apparently artists are not that fundamentally different and perhaps there is even an underlying connection between the cognitive processes that give rise to both arts to both arts and sciences. According to the passage, the current findings______.
A. present the working mechanism of the right and left brains
B. challenge the popular division of right-or left-brain learners
C. reveal the fundamental differences between artists and scientists
D. interpret the different cognitive processes in scientists and artists
