But if someone copies that behaviour would they get the same benefits?

Some correlated traits: * mimicking. A critical skill, which is poorly encouraged as a general skill, and as adults we often have habits or beliefs that interfere with it. * perseverance and repetition * exploring/using different ways of learning and working out what are effective means of learning and ignoring invalid common techniques. * Avoiding book learning and rule based learning.

My belief is: look at how a baby or child manages to do it, try to do what they do, and avoid using any parts of the brain they don't use when learning. Not to say I am fluent in another language, just to say what I see in successful second language speakers, and how I try to begin learning (I mostly lack perseverance and repetition!)
