Having learned a different language through immersion at adult age (30+), whether or not you get the feedback is culturally dependent. In France, you would get this feedback more often than in, say, the Dutch or Swedish language areas.

That said, I think it's not just getting feedback that counts, it's also being open to feedback. Relative to an adult, a child doesn't mind getting embarrassed as much. Adults often don't want to lose face, and are then less likely to learn the language with full abandon. Natural language learning ability aside, I made quicker advances than other people because I didn't care about making silly/stupid mistakes but others did.
