My children discuss behavior and social interactions as easily as they discuss Nintendo or their own cats and dogs. When I was their age, psychology, comparative religion and anthropology were far in my future. My kids might not have much formal terminology, but they're extremely conversant and certainly can think in those areas without knowing they're too young (by the book) to do so. They understand well that there are many versions of historical events. They understand that there are different ways to act in different situations, and with people who have particular beliefs and preferences. Some adults could use knowing that.
