Contemplating Extinction


No not that extinction!
I am not really interested in the debate over what killed off the dinosaurs. (Last I heard we are back to asteroid bur my personal theory is Zombie virus.)


I am thinking about the term extinction when used in the context of learning theory and behavior. Extinction refers to the withholding of reinforcement for a previously reinforced behavior in order to eliminate that behavior*.

We have all heard the advise ignore it and it will go away. Sometimes we encourage behaviors we don't want in our horses accidentally. When we realize it we put the behavior "on extinction" or we consciously withhold our reinforcement. The reinforcer is usually our reaction to the behavior. This is a common treatment for attention seeking behaviors like vocalizations, pawing, nosing etc. I have also heard trainers recommend ignoring horses that spook or shy. Heather Blitz described a spook as a ripple in a pond of your schooling session or test. By reacting in anyway you are making a bigger disturbance in that water. Your objective as a rider and trainer is to keep the water flowing and still in your ride(I am paraphrasing).

If the behavior is not immediately endangering you or the horse I believe that putting the behavior on extinction by ignoring it or by replacing the behavior with a more desirable and incompatible behavior with the undesired one, are all you need in your tool box to reduce unwanted behaviors.

What about the other side of the coin though? How often do horses quit performing behaviors that we want because we have accidentally put them on extinction? Horses trained with negative reinforcement (which is to say almost all of them) usually become dull to aids or cues because of poor execution of negative reinforcement causing habituation. Negative reinforcement is an exact science and to err is human so all of our horses probably suffer at some level with habituation to our aids ( I know mine does). I wonder though if extinction has a role to play as well in the dull horse?

In the beginning of acquiring a new skill the rewards are big (or at least they should be). Think about how you approach teaching your horse something new. How do you show him he is doing well? A big release of the inside rein? A nice rub on the crest or whithers? A rest? A treat? Whichever form you decide to deliver your reinforcement you are providing feedback on what behaviors you want while simultaneous providing incentive to repeat the new behavior in the future.

So what about those tried and true behaviors or those "push-button" horses? What do we expect our horses to do automatically? Sometimes extremely well trained horses "forget" well formed behavior or offer a lack luster performance. In some instances I think this happens because we have stopped giving feedback. Just like people, horses require feedback even on tasks they perform with confidence in order to know the behavior is still what you want.
Additionally who would want to continue to preform a task with no reward or recognition?

I guess the take home message is this. If you are having issues with a horse not performing a well rehearsed behavior or motivation in your equine in general make sure you are providing consistent feedback so your horse knows when he is getting it right!

Enough contemplation back to what really matters.... Bodhi!
I got in a quick ride today right before a downpour. Bodhi.was.awesome. He was forward but listening to even the lightest aid of my seat, legs and reins. He felt amazing! It was definitely a ride to hold on to when problems will arise again. It only lasted ten minutes and during our 2nd canter the sky opened up. We made a B-line for the barn after that and waited for the rain to lighten up.
As Bodhi stood drying off by a fan I played with the barn manager's nervous Nancy TB and a boarder's TB on stall rest. They both love to play clicker games and I like to give both of those high energy high and intelligence horses something to do for a few minutes to elevate the boredom.
After the rain let up a bit Bodhi and I jogged together at liberty back to his pasture. Before I left him to graze I took the opportunity to work with him in some of the forming puddles. He was willing to walk and trot through them at liberty and finally even backed into a puddle! So proud as he is not a fan of water. What an idyllic day with my golden boy!

Reinforcement: an Introduction

First what does it mean to reinforce? Reinforcement is a reward for a "right answer" Reinforcement is anything that increases the likelihood of a behavior recurring. What ever behavior is reinforced will then likely repeat. I like to keep this in mind when new behaviors pop up in horse training. "What behavior am I reinforcing and HOW am I reinforcing it"

The How
There are two basic types of reinforcement. Negative and positive reinforcement.
Positive- Is anything added that is rewarding when the appropriate behavior is expressed. Giving a dog a cookie for the command "sit", smiling at your partner and saying "thanks" for doing the dishes, giving a child a gold star on a completed homework assignment- these are all examples of positive reinforcement. Exotic animal trainers(dolphin elephant etc) use positive reinforcement. "Clicker" training is a gaining popularity, and also uses positive reinforcement- a topic for another post!

Negative-(not to be confused with punishment) is taking away an irritating, non rewarding, or uncomfortable stimulus. How we normally train dogs to walk on a leash is using negative reinforcement. A new puppy quickly learns that he can remove the uncomfortable feeling of tightness from the rope by walking forward, the same a horse is conditioned to move "off" a leg. The reward is in the removal of the stimulus or "aide" as we riders like to say.
Most traditional and "natural" horse training is primarily negative reinforcement. Leg and rein aides are of course negative reinforcement. You want your horse to move away from your leg, you want your horse to give to reins. This is all taught by negative reinforcement. Also Parelli's Seven Games uses negative reinforcement, along with Monty Robert's join up games. So you see in the eyes of a behaviorist the new "natural" movement is not so new or different after all!

Both forms of reinforcement have their own unique weaknesses and strengths, and just like disciplines have very passionate followers. I plan on delving into the drawbacks of each in following posts...

Bodhi News
The cold is finally here, in North Central Florida and Bodhi looks like a woolly mammoth. He just loves this weather! I am debating what I am going to do about blanketing this year. He is a Haflinger and I do live in Florida. Does he really need a blanket? Is this just to make me feel better? I am thinking about loaning Bodhi's Blankets to two ederly boarders who do not have any blankets. They are two short coated arabs that need all the help they can get keeping the pounds on this winter.

At what temp do you blanket your horses? What role does their individual winter coats weigh in your decision making process?
