Is anything known how effective is "non-focused" learning. For example when I am focused on something else (watching TV, doing work in the office) while listening to language learning material (words and phrases and their translations for example). Or playing scales on your guitar while watching TV (okay, seem to be more invovled then merely listening, but I guess you get the idea).
So is there anything known about that, or any studies on that?
EDIT: I do not have found any studies, mainly because I do not know what to search for, googling terms like "non-focused learning", "passive learning", "distractive learning" do not give anything useful. I have a minor in psychology and if I see a study I can relate it to what I am looking for, but I am not a researcher in psychology. So this question came up out of curiosity of my own (and to be honest, its quite practical if possible to learn something by "not even trying" to say in lax language). I know about the 10k rule of expertise, and they always talk about "deliberate practice", obviously the kind of practice I am looking for is not deliberate, but maybe someone asked if its still beneficial, even if on a much smaller scale. I would suspect that it is not difficult to design studies for it, just let people perform some task, tell them its the main task, then do some distraction in the background (which is the supposed learning content, melodies, words whatever). Then afterwards (obviously to the surprise of the subject) ask question about that your let it perform a task to access gained knowledge.
