Familiarity is one factor in enhanced learning, but possessing a strong interest in the subject matter also contributes strongly to understanding it. I would venture most students major in a specific subject because they're genuinely interested in it (certainly some do because they think it will be lucrative while others are following what they're parents told them to do!). If you study something you enjoy, Bjork's process is essentially moot: your mind will understand and comprehend the material because you are focused on it. I chose to study engineering since I like the topic; if I followed Bjork's method, it would be all jumbled and take away the fun of learning.
