“Dear Zaquie, November 1st
Thank you for your interesting reflections. Do please do some more tests in your next class. I think your ideas of letting people feel are good ones to test, and another thing worth testing would be to find out if people can get better with practice. This might be possible if they get feedback trial by trial. In other words if they are told if they’re right or wrong each time. This could also have a negative effect, because if people are wrong they get discouraged and self-conscious which interferes with their performance. So you might like to investigate it with and without feedback to see what happens.
