@Scribbler I agree, there are times when negative reinforcement is necessary when safety comes into play. However, I do believe that there is a great benefit to the horse when using mostly R+, but to each their own!
I found your post about extrinsic vs intrinsic reward very interesting. The motivation for a horse to do a job should absolutely be intrinsic! Unfortunately, I believe the way that most equestrians train remove that intrinsic joy in a horse to move and work, and the way to reinstall that joy is through extrinsic reward. My love for photography is intrinsic; I could photograph and photoshop all day long just because I think it’s fun. But if someone forced me to photograph when I didn’t want to, or placed me into a situation where I did not feel comfortable photographing or the act of photographing became unpleasant, I would most likely not want to practice photography anymore. Forcing a horse to do a task for longer than they would like, perhaps in a way or in a place that is uncomfortable, distinguishes the joy for that task.
@Bluey I appreciate your advice, and I agree that it is essential to keep an open mind. I’m sure that throughout my training progression, my ideas on training will shift as I begin to practice certain things myself.
@S1969 Any animal is capable of learning through the four quadrants of operant conditioning. Which quadrant(s) you use in your training and the frequency at which you use each one are dependent on what you personally believe is most effective, as well as your priorities throughout and at the end of the training process. I would say that anyone who has chosen to focus on one of the four quadrants of operant conditioning likely fully understands how they work and affect an individual, and has made their decision based on that.
@sophie Clicker training under saddle is a bit tricky. My mare learned that a tap on the neck meant that I wanted her to turn her head for a treat. You could also let your horse rest after they perform what you ask, or let them graze for a moment. To achieve flexion with +R, you do exactly what you said! You encourage the horse to flex on their own, and reward them for the flex. Flexing the neck is a natural movement for a horse to do, but only to a certain point and for a certain amount of time. I can touch my toes for a brief moment, but if someone tried to get me to place my hands flat on the floor, that would hurt. Just as I would have to stretch consistently to get more flexible, so does your horse, and by asking for the flex with R+, you let the horse choose how far and how long he can hold it for. Eventually, as your horse becomes more flexible, you can ask for longer and deeper stretches (holding the carrot further away and for a longer period of time). Once your horse knows how to do the movement that you’re asking for, you can add a gentle cue with the halter/bridle and combine it with the carrot, and then slowly remove the carrot entirely.
@longlanefarm That is an interesting point. I feel that since horses are large animals, and thus more threatening, training methods are geared to yield the fastest results and the most control, and now it is the norm to train in that manner.
