Nice article!
One of the paragraphs says:
Prior research on highly trained musicians and early bilinguals revealed that enhanced brainstem responses to sound are associated with heightened auditory perception, executive function and auditory communication skills.
I'd be very curious to learn more about this prior research. Communication skills and auditory perception are very helpful, but executive function has been shown to be a huge indicator for success in life...
I wish they had said what constituted "highly trained"
I'll have to do a little digging when I have time. Thanks again!
