Using Operant Conditioning to Let Horses Choose Warmth?

Most of the communication that horses receive is from human to horse, we always are telling them what to do and when. However, with newer research being put into teaching animals to communicate one barn has taught horses to communicate when they want to wear a blanket or not. Learning theory has been increasingly becoming more popular in the equitation world, giving us more of an insight into the cognitive abilities and preferences of horses.

One barn used reward based operant conditioning to teach horses to touch a board, and to understand the meaning of three different symbols (Mejdell, 2016).

Visual symbol boards given to horses. To the left, the horizontal bar meaning “put blanket on”, in the middle the blank board meaning “no change”, and to the right, the vertical bar meaning “take blanket off”.

Operant conditioning is teaching animals to form associations between behaviors and resulting events. In this case the behavior was touching a board with a symbol, and the resulting event was removing or putting on a blanket. The researchers use positive reinforcers to shape the behavior they wanted. Shaping is reinforcing behaviors to get closer and closer to a desired behavior (Mejdell, 2016). So, in this experiment they started with reinforcing just the horse walking up and touching the boards, then they continued reinforcing the behavior and added the resulting consequence until the horse understood desired behavior.

The steps that the trainers went though to make sure that the horses were able make a “free” choice.

The reinforcer in this experiment was positive reinforcement, this is when you add a desired stimulus, and in this case, it was horse treats. The treats were a primary reinforcer, meaning that they were something that the animal finds inherently reinforcing. The researchers also used clickers as a secondary reinforcer  as a bridge between the behavior and the primary reinforcer. This was so that there was no lag between desired behavior and positive reinforcer (Mejdell, 2016).

Here the horses are choosing which board to pick.

The experiment was done because of a commonly disputed management technique in the winter. To blanket a horse or not to blanket a horse. They hoped to be able to “ask” the horse whether or not they wanted a blanket, and then record the temperature that they chose a blanket to better understand when horses truly felt cold (Mejdell, 2016). The experiment used 23 horses, 13 cold-blooded, 10 warm-blooded, 3 Arabians, and 1 Thoroughbred. All ages from 3 to 16. The positive reinforcement training was done by an animal trainer, and they used this training to teach horses to choose whether they wanted a blanket on, off, or not changed. The horses, once the symbols were learned, was given a single choice and given a consequence (Mejdell, 2016).

Though this experiment they found that horses were able to discriminate between simple visual symbols (the boards) and extend that to associations of different outcomes (the blanket on or off). As could be predicted, horses preferred to wear a blanket during bad weather and stay without a blanket in nice weather. When 10 horses were tested on sunny days with a relatively high temperature (about 68 degrees Fahrenheit) all 10 choose to have their blankets off, and when they were tested on another day with and temperatures about 41 degrees Fahrenheit these same horses choose to keep their blankets on (i.e. no change) (Mejdell, 2016). The understanding of choice showed the horses were able to understand the effects that the blanket change would have on their thermal well-being (Mejdell, 2016).

This experiment paved more paths for operant conditioning to be seen as a successful way of training horses. Within the past two years positive reinforcement, and clicker training have been becoming more popular. Many people are now realizing that horses are very motivated learners, and can easily distinguish and learn what is right and wrong. From my own personal experience with operant conditioning with horses, I have found it very easy to teach a horse different tasks using positive reinforcement. Such as lifting their feet, coming in from the pasture, heeling, ground manners, and overcoming fears (because horses are naturally flight animals). They pick up on cues and body language quickly, and will do anything for a reward.

The Misinformation Effect

The Misinformation effect is when there is misleading information into someone’s memory of an event. This effect becomes important after a dramatic event when someone’s memory may be hazy due to adrenaline or stress (Arndt). One of the main researchers who developed the Misinformation effect was Elizabeth Loftus (Cherry), and her most notable experiment was having people watch a car crash, and asking them a series of questions about the crash. However, in the two groups she changed the way she asked the question, swaying the viewpoints of the people who watched the crash.

Why Does the Misinformation Effect Happens?

If, after a dramatic event, misleading information is presented to a subject, this information can either get blended into the memory or overwrite the memory completely. There has also been research into the idea that the newer misinformation is easier to retrieve, and that the original memory was never actually encoded to begin with (Arndt).

If the misleading information is presented after a longer period of time then it will be harder for the person to retrieve the original, correct information. Another way that information can be distorted is by talking to others who experienced it, or by watching the news. This is because almost everyone experiences a traumatic situation differently, so if one person shares their story you might bring some of their experiences into your story.

Why is the Misinformation Effect Important?

The Misinformation Effect is very important in witness accounts to crimes. The reason for this is because if the interrogator uses leading questions then a witness may be swayed to answer a certain way. This is also why witnesses are normally kept apart, because if they were allowed to speak together, then one-person misinformation could be spread to the other. When you are a witness to a crime the interrogators try to contact you as soon as possible to that you are not able to be swayed by news, or lose the memory over time.

My experience with the Misinformation Effect

When I was a child my brother got attacked by a dog, he was maybe 12 at the time and I was nine. He had been jumped on by a large black lab that bit his arm, back, and leg. We even have a picture of him at the time standing there, looking at his arm with teeth hanging out of his back. I can picture that entire memory like it was just a few years ago. However, at a family dinner just a year ago I found out that I wasn’t even awake that night. I was upstairs sleeping while my mom drove my brother to the emergency room. But in my mind, I can see his whole back and arm covered in scratches and the teeth still there. I have the vivid memory of my dad taking the picture, and sitting there wondering why he wasn’t more upset by the fact that a dog just buried his teeth in his back. Now I know that this memory was made by my mind, built off a collection of stories I had heard from my other family members that night. I hadn’t actually experienced any of the stress from that night, and I was actually totally oblivious as to what was going on.

Prozac; How it Influences the Brain

Fluoxetine, better known as Prozac, is a common antidepressant used by many patients. Prozac is a selective serotonin reuptake inhibitor (anSSRI) meaning that it increases the levels of serotonin in the brain (Mayo Clinic).

Serotonin is a neurotransmitter in the brain that is known for creating feelings of happiness. The SSRIs block the reuptake of serotonin into the neurons, allowing for more serotonin to be readily available for more transmissions between neurons (Copeland).

As you can see in this picture, before Prozac is being taken the serotonin being sent to the neuron gets deactivated via reuptake, and overall there will be less serotonin transmission between these two neurons. With someone who is experiencing depression, and already has lowered serotonin levels, this reuptake hinders their ability to feel happiness. When a user is on Prozac, it blocks the synapse that the serotonin travels through and allows for more ‘messages’ to be sent to the serotonin receptors. The increases messages allow for the user to increase their serotonin levels, and feel better (Copeland).

Fluoxetine doesn’t just help with the treatment of depression, it also helps with anxiety. So, sometimes doctors will prescribe Prozac for people with obsessive compulsive disorder or panic disorder. However, when taking Prozac patients have to take it on a scheduled dose, meaning if they’re taking it every day skipping one or two days could be a detriment to the patient. Depending on dosage the drop in serotonin levels from the SSRI not inhibiting the reuptake of serotonin could create an unstable mood decrease of the user. Causing the patient to have a delayed manic or depressed episode, and making them feel that their antidepressant isn’t doing its job.

When I was getting treatment for depression, one of the first antidepressants they put me on was Prozac. It’s a treatment that has been around for so many years (since the 1970s!) there are very little side effects, and it is able to be started at a very low dosage with little to no titer on or off. Meaning that you really don’t have to move up dosages over long periods of time (5mg to 10mg to 20mg as your final dose) like some other antidepressants that might shock your system more. Prozac didn’t work the best for me, even after a few dosages increases. This happens to people sometimes; some people react better to antidepressants than others. This makes finding an antidepressant that works generally hard because of the large adjustment period for the medication to take a true effect.  Understanding how Prozac worked allowed my doctor and I to work together to find an antidepressant that might work better, and we were able to try an antidepressant that wasn’t an SSRI and we were more successful.
