To help someone improve at dance or sport, ignore poor performance but reward good performance immediately, for example by shouting "Good!" (Buzas & Allyon 1981) The reason you should ignore poor performance if you say "No, you're doing it wrong!" you are inadvertently punishing the effort. A better response to a mistake would be to reinforce the effort: "Good effort! You're almost there! Try once more."
I got a demonstration of how true this is yesterday when, during my taekwondo class, I was paired up with one of the senior black belt students, who has some but not a lot of experience teaching. He was supposed to be fixing up my poomsae (same thing as a kata in karate) and each time he watched me do it, I would finish and he would immediately launch into a description of what I was doing wrong. His feedback was pretty useful–specific, with demonstrations of exactly what to change in order to do it right–but without any prelude of "yay, good job!" or even "okay, the punches were way better that time...now let's work on the stances", I found myself getting really discouraged. Reminding myself that I wasn't actually doing worse than usual, that he just had a different teaching style, helped a little... But my subconscious brain still decided to feel resentful and unenthusiastic, no matter how counterproductive that might be towards my actual goal of improving my poomsae.
As a swimming instructor, I do make sure to dole out a LOT of praise, but I'm wondering if I should push it even further...
I'm not sure a lot of praise is a good idea since that would lower its effectiveness as a reinforcer.

Story 1:
On Skype with Eliezer, I said: "Eliezer, you've been unusually pleasant these past three weeks. I'm really happy to see that, and moreover, it increases my probability than an Eliezer-led FAI research team will work. What caused this change, do you think?"
Eliezer replied: "Well, three weeks ago I was working with Anna and Alicorn, and every time I said something nice they fed me an M&M."
Story 2:
I once witnessed a worker who hated keeping a work log because it was only used "against" him. His supervisor would call to say "Why did you spend so much time on that?" or "Why isn't this done yet?" but never "I saw you handled X, great job!" Not surprisingly, he often "forgot" to fill out his worklog.
Ever since I got everyone at the Singularity Institute to keep work logs, I've tried to avoid connections between "concerned" feedback and staff work logs, and instead take time to comment positively on things I see in those work logs.
Story 3:
Chatting with Eliezer, I said, "Eliezer, I get the sense that I've inadvertently caused you to be slightly averse to talking to me. Maybe because we disagree on so many things, or something?"
Eliezer's reply was: "No, it's much simpler. Our conversations usually run longer than our previously set deadline, so whenever I finish talking with you I feel drained and slightly cranky."
Now I finish our conversations on time.
Story 4:
A major Singularity Institute donor recently said to me: "By the way, I decided that every time I donate to the Singularity Institute, I'll set aside an additional 5% for myself to do fun things with, as a motivation to donate."
The power of reinforcement
It's amazing to me how consistently we fail to take advantage of the power of reinforcement.
Maybe it's because behaviorist techniques like reinforcement feel like they don't respect human agency enough. But if you aren't treating humans more like animals than most people are, then you're modeling humans poorly.
You are not an agenty homunculus "corrupted" by heuristics and biases. You just are heuristics and biases. And you respond to reinforcement, because most of your motivation systems still work like the motivation systems of other animals.
