I just posted in another thread that I am in the process of learning a second language. I've used back chaining on my dogs before to string longer behaviors together, and was always surprised and impressed on how much easier they caught on when I did this. (A good example is a recall. Start with finish. Then front. Then add the recall, etc. Instead of asking for a recall, then a recall with a front, then a recall with a front, then a finish.)
Well, in my language course, when learning new phrases there's a whole lot of back chaining going on. If I was learning to pronounce "How Are You", the pronunciation starts with learning how to say "You." Then "Are". Then "Are You." Then "How". Then "How Are You". I'm amazed at how quick I am picking this stuff up.
