The Cognitive Component of Language Learning

i don't know whether i have a clean answer for where they separate. It seems like there's probably some aspect, at least when you are learning a language, a that you learn kind of 'blur' into each other. I'm sure there's someone who's done some research that sort of fit it together. But i do think, like the cogive component, i think is important because it underlies a lot of skills. And it underlies many things that we find particularly difficult about learning skills.
