> Does negative emotional reinforcement really work at such long time remove? So, I don't know about regret specifically, but when researchers asked people to remember instances where they felt specific emotions, and asked how strongly the emotions reoccurred during that process, the number one emotion was embarrassment. Some theorize that fear of embarrassment driven by memories of making mistakes is one of the leading factors in the fluency gap between the first and second languages of children to foreign parents (who speak English [or the language of their peers] much better than their parents native language, even when their parents don't speak English at all -- somewhat odd considering children _need_ to communicate with their parents to survive and get basic needs met).
