The studies you linked are garbage not related to the only part that matters - learning. What they measured is that if you ride a bike while listening your legs will have higher muscle activity, and so will your brain that managed those legs.
There is only downside in distracting yourself to have to copy everything verbatim instead of, you know, actually focusing on the material being presented
good handwritten notes do not copy everything verbatim. You tend to summarize as you write it. That is part of the learning process.
