Not everything can be practiced extensively, but fortunately not everything needs to be practiced.... If practice makes mental processes automatic, we can then ask, which processes need to become automatic?
Retrieving number facts from memory is a good candidate, while a science teacher may decide that his students need to have at their fingertips basic facts about elements. In general, the processes that need to become automatic are probably the building blocks of skills that will provide the most benefit if they are automatized. Building blocks are the things that one does again and again in a subject area, and they are the prerequisites for more advanced work.
So before I write to you about my thoughts on this subject, can I ask you: which processes need to become automatic in our work with horses?
