CARS Research intro

I would say that the general area of my research would be in the area of children learning to be digitally literate as young as possible, and then comparing this to people that are older learning (pretty much teenagers and above), who learn at their older age. My question is pretty much "Does the age at which one learns to become semi digitally literate, or at least be introduced to technology, affect the difficulty at which they learn and the speed at which they learn other aspects of digital literacy in the future. My goal is to find any studies or other professionals' views on the subject so I would not have to conduct an experiment myself.
