SATS - wots all that about, then?

A friend has tried SATS on their dog and is really pleased with it as a methodology. I must admit I'm quite confused as to the science of how it works compared to clicker training. There is more talk, more explaining does this mean more anthropomorphising during training?

I'm not switching or trying anything yet. Just having a look and posting the info.

I found these links of what it sounds like and some videos on the site.
