We're still in the process of finding out what the factors are that do change. What certainly does change more often than not is the makeup of the sound signal. I'm deliberately not calling it “quality of sound”, because that's a laden term in itself. There might be other factors as well, including visual input or the necessary multi-tasking, which increases tremendously when you have to interact with a platform set-up like the one I'm using right now. I have to process at the same time signal forces in different modalities that come at me, which they usually do not.
Some of this might be a matter of training, but I am afraid to say that the human brain, most likely, did not make as great a stride as technology did over the past few years.
