Ok so since this came up in another thread, I think it'll be our first theory discussion topic! and if you haven't read the sticky "The Purpose of This Section" please do! NRM's are a word or a sound that's considered by users to be completely neutral, kind of like the "Hot/Cold" game we played as children. However here's the controvercy: Advocates believe it's giving constant feedback, and that's all it is. It is a neutral word that means that was wrong and try again (supposed to help extinction) Those opposed to NRM's believe that they are, infact, adversive (however mild) and it is unnecessary and can actually be detrimental to use them in training. Here's an article from Karen Priors clickertraining website: http://www.clickertraining.com/node/2848 I do use them with Oliver, as he seems to need constant feedback, but I wonder if it's because he's my crossover dog, and I didn't know enough about it, and we've both become dependent on NRM's I do not use them with Mouse, as she's way happier throwing out behaviours at me and doesn't need a "cold" button LOL Ok so the point of this thread, we will discuss the finer points of NRM's, (for and against) and the more articles, the better!
