How does music help a child to retain words? Chan believes that learning music stimulates the left temporal lobe, which processes auditory input. This in turn encourages the development of a part of the left temporal lobe called the planum temporale, which responsible for verbal memory. In this way, verbal memory training happens as a sort of 'by-product' of musical training.
When it comes to music training, it is not the instrument or the type of music but the actual process of learning that helps verbal training, said Chan.
After one year the musically trained children performed better in a memory test that is correlated with general intelligence skills such as literacy, verbal memory, visiospatial processing, mathematics and IQ.
it is very interesting that the children taking music lessons improved more over the year on general memory skills that are correlated with non-musical abilities such as literacy, verbal memory, visiospatial processing, mathematics and IQ than did the children not taking lessons.
One of the study’s authors, Nina Kraus, said the findings suggested that studying music “actually tunes our sensory system.” This means that schools that want children to do well in languages should hesitate before cutting music programs, Dr. Kraus said. She said music training might also help children with language problems.
