Positive reinforcement training is all about giving a reward to reinforce the behaviour you want more of. The key word is giving. If you have never used a bridge signal before, you start with the simple act of giving. In return you will get your horses’ attention. Then ‘training’ can begin.
Introducing a bridge signal (click)
When you introduce the clicker or another bridge signal to your horse, you start with just clicking and giving rewards. No strings attached. After 30 – 50 repetitions (often sooner) of click = reward, the horse will try to figure out what made you give the treat and if he can influence this by his behaviour. In other words: he will start trying different behaviours in order earn a treat. He is ‘asking’ you what you want from him!
You will notice that it is very easy to teach your horse new behaviours and within a few clicks he is offering you his new trick more and more consistently.
Let’s take targeting as an example. You want to teach your horse to touch the target stick with his nose on cue. You start with presenting the target stick (a stick with a ball attached on the end) to your horse.
In the beginning your criteria are low: it doesn’t matter where he touches the target stick as long as he touches it. If you want to set it up for success, you make the desired behaviour (touching the target stick near the target & touching the target itself) much easier than the less desired behaviour (touching the stick near your hand or touching your hand). So that’s why you start by working with a barrier in the beginning.
Introducing a cue
Once your horse is offering a certain behaviour consistently you can add a cue. In this example: your horse is touching the target predictably and he knows that touching the stick isn’t getting him rewards.
You might have worked with a training cue , e.g. presenting the target stick to your horse is a cue in itself. The horse might have associated specific conditions and consider them as cues we are not even aware of. Maybe you are always in the same place (stall, with a barrier) or at the same time of day when you were working with the target stick.
Temporary (training) cue
Sometimes this temporary cue (presenting the target) is not a very useful cue in other circumstances and then it its time to introduce your ‘official cue’. You don’t want your horse to touch the target stick all the time… It would be rather annoying if he puts his nose to the target whenever he sees the stick. Your horse can become very frustrated if you click offered behaviour sometimes, but would click it every time. That’s why you need a cue. The cue means ‘you can start earning rewards now’.
Changing cues: from temporary cue to final cue
So if your horse is offering to touch the target consistently it is time to introduce an ‘official (final) cue’ e.g. the verbal cue ‘Touch’. You start by using the new cue before the ‘training (temporary) cue’.
Horses will quickly anticipate this and when he starts acting on the official cue you capture his behaviour with a click.
After some repetitions where you can click & reward after the behaviour occurred after you have given the new cue you can raise your criterion.
Now you only click & reinforce when you have given your final cue for the behaviour. If your horse acts on the temporary cue or offers the behaviour spontaneously you don’t reinforce it. This is the final step in training a behaviour.
You might notice, because you changed the criteria and he doesn’t get reinforced so easily, that your horse will try harder to make you click & reinforce. You might see a duration in touching the target or something else you want to reinforce. Ignore this.
It is important to be consequent: final cue + behaviour= click and reinforce, spontaneously offered behaviour does’t lead to a click anymore in this stage of training.
If he tries really hard and you see improvement in the behaviour take advantage and simply give your horse a chance to earn a click by offering the new cue to him. He will learn to pay more attention and figure out quickly when he can and when he can’t expect a reinforcer.
Final step of training a behaviour
The final step in the process of teaching a behaviour is to use the new cue in different circumstances. If your horse performs well in different situations, he has generalized the cue. Well done!
Changing context: now Leon is holding the target stick and giving the command.
A horse learns a certain behaviour in a certain context. Therefor it’s best to start training new exercises always in the same spot, for instance the round pen where you have the advantage of working with protective contact (a barrier).
If you want to test your new cue you have to shift one or more of the conditions (the context) your horse was learning a specific behaviour in. Now you ask to touch the target without a barrier between you two, or you ask it in the outdoor arena instead of the roundpen or at a different time of day and so on.
This will ask the horse to adjust and generalize and ignore certain ‘cues’ in the context and pay more attention to others, your new cue. Sometimes a horse seems to lose all his skills in a new context because the cues he had paid attention to are not there anymore. Always lower your criteria temporarily if you change the context of learning, so your horse will gets his confidence back quickly.
