I would hate to see what my verbal ability would have been like if I hadn’t studied music:
While it is no surprise that the young musicians scored significantly higher than those in the control group on two skills closely related to their music training (auditory discrimination and finger dexterity), the more surprising result was that they also scored higher in two skills that appear unrelated to music—verbal ability (as measured by a vocabulary IQ test) and visual pattern completion (as measured by the Raven’s Progressive Matrices).And furthermore, the longer and more intensely the child had studied his or her instrument, the better he or she scored on these tests. Studying an instrument thus seems to bring benefits in areas beyond those that are specifically targeted by music instruction, but that is not the end of the story. Although this research sheds light on the question of whether connections between music and other, unrelated skills do exist, more studies examining the causal relationships between instrumental music training, practice intensity, and cognitive enhancements are needed.
