Mindfulness while Studying or Listening to Dhamma Talks
Uilium. I hope you are well my friend. I think if you were to view things from an experiencial point of view- so acknowledgement of all experience through sensory input ( the 5 aggregates)seeing, smelling, tasting, touching...etc. Also the body can multi-task but the brain can not, for example you can only think one thought at a time, you can't think of both a banana and an elephant simultaneously, unless you combine them, then it's still only one thought being processed. 

So back to your question specifically, when i read, i listen very attentively to my voice, but if i'm reading in my head, then i might focus on the touch or feeling of the book or pages. Wherever the mind goes, just focus on that during your studies. 

I hope i have helped in some way, my friend.
Metta.
