Errorless Learning
“Errors are not a function of learning or vice versa, nor are they blamed on the learner. Errors are a function of poor analysis of behavior, a poorly designed shaping program, moving too fast from step to step in the program, and the lack of the prerequisite behavior necessary for success in the program.”
— B.F. Skinner, The Technology of Teaching, published in 1968
Errorless learning is a positive reinforcement concept that concentrates the most on the antecedent portion of training. It is predicated on the concept that errors are not necessary for learning to take place. In fact, errors or mistakes often cause confusion and frustration in the learner, which often gets in the way of the learning process, especially when errors are met with punishment, either negative or positive.
A lot of trainers in the horse world may still work very much off of the trial and error method, which I want to be clear, I still use, and it does have its uses in a lot of training scenarios. What it is not good at is teaching reliable, consistent behaviors. Even if the horse is not getting reinforced for an unwanted behavior, they are still practicing it, thus strengthening the neural pathways that lead to that behavior. I will talk more about this next week.
What is the alternative to trial and error, you may ask? The key lies in knowing your learner. In errorless learning, the idea is that you set the horse up so well that they guess the correct answer on the first try, either through prompting with other known behaviors or through setting up the situation so well that the most likely thing for the horse to do is to offer the wanted behavior.
One example of when I used errorless learning was when I wanted to teach my horse Loki to get in the trailer. I started by teaching him to step on a tarp because I knew that if he saw a tarp, for whatever reason, he really wanted to go and step on it, since he would often do this when left to his own devices in the vicinity of a tarp. So I just strengthened that behavior by marking and rewarding for it.
Then I generalized that to a plywood board under the tarp, then slowly moved the tarp off of the board, slowly built walls and a roof around the board until eventually I placed the board in our horse trailer. During this entire process, Loki never did not go and stand on the board, and once he was easily going to the board in the trailer, I took the board out, and if the doors to the trailer were open, he would just go in. At no point in this process did he ever not do the wanted behavior. I was able to raise criteria at every session, and he easily learned the wanted behavior without me ever having to withhold reinforcement or correct him for making a mistake.
This may be a positive reinforcement concept; however, there are ideas in errorless learning that can be useful in negative reinforcement.
The first of these that I find useful is the creativity to set up a horse to be successful. A lot of good trainers will describe this as making your idea his idea. For example, if I want to teach my horse to go forward in a straight line, I will likely ask him to do that when he is facing in a direction that he already wants to go, such as going towards a gate or closer to his friend.
In the early stages of training, don’t ask for things you are not reasonably sure the horse not only can do but is ready to do. For instance, if my horse has never been in an arena before and I want to work on getting their attention on me, I am probably going to choose to work with them in their stall or pasture where they are comfortable and there are not a lot of distractions, and have an established way to request their attention before moving them to the arena.
If you need to do something for your horse’s health, for example, your horse needs to see a farrier or has an accident and needs to see a vet, and you have not had time to train them for that experience, do not be afraid to ask for drugs to make it easier for the horse. Then work very hard to prepare the horse for the next time.
There is so much more to errorless learning. Hopefully, you find this brief overview helpful. If you want to learn more, I have attached a link to a really good starting place that cites many more sources, or comment below if you want me to do more posts on errorless learning.
As always, feel free to reach out with questions or comments, and remember to enjoy your time with your equine partners.
