This paper, published in the Philosophical Transactions of the Royal Society Biological Sciences Journal sites impulsiveness as a timing disturbance.
Here they use medication to correct the timing disturbance; IM uses direct training in timing.
What has still to be researched is, what IM tasks impact what parts in the brain. We know children with ADHD and impulsivity gain in attention and impulse control with IM, but are there certain tasks that are specifically helpful for these specific challenges? My guess is both yes, and no. Yes, because different parts of the brain have different functions. No, because timing is located seemingly through out the entire brain. Every part of the brain uses timing. Timing helps all the members of the orchestra play together, all parts of the brain fire together. Timing is the brain's conductor. Time will tell. :)
