Language learning is correlated with socialization. We learn by communication with other people. As people get older, it seems they have a harder time making new friends and knowing new people. I wonder if this explains part of it. Perhaps the average adult learner, even when fully immersed in a foreign language environment, doesn't socialize with other unfamiliar adults as readily as a child would do if left to play with other children. Less socialization = less language practice = slow learning.
