I recently spent a week in Germany at the Scientific Symposium of The BHV, a German dog training association. I was privileged to get to give a lecture about errorless learning at the symposium. Then, after the symposium, Dr. Jesús Rosales-Ruiz and I gave a two day workshop about shaping to a wonderful group of about two dozen trainers.
During part of one of his lectures at the workshop, Dr. Rosales-Ruiz discussed the concept of shaping movements versus shaping outcomes. This is not a topic often discussed by animal trainers, but it is a really important one. I know that when I first heard about it, it changed the way I think about shaping and clicker training.
