Sorry, I totally borrowed “Pegasus wept.” from the Equine Observer . It’s just so fitting.
There are quite some misconceptions about clicker training, trick training and positive reinforcement training. Let’s divide the trick myths into 4 parts:
1. “He is just doing it for the treats.”
If that is true, we would have to look at the horse like it is a rat in a box. In that case, an aversively trained horse (‘Natural’ Horsemanship or traditional methods) is only doing it because of the threats.
2. “Positive Reinforcement = Bribing.”
If that is true, then Negative Reinforcement = Blackmail. Bribing, however, doesn’t begin to describe what positive reinforcement really is and does. Bribing often comes before the behaviour, and a reward (the reinforcer in this case) comes after the behaviour.
3. “Working with treats is just for tricks.”
ALL behaviours are ‘tricks’ to the horse. If you can negatively reinforce it, you can also positively reinforce it. Positive reinforcement based methods are just a lot younger compared to negative reinforcement based methods so we have less to show for in the eyes of skeptical people (right now!).
4. “If it has been trained with treats, it’s not ‘REAL’ (a trick)”
R- based methods are much older and it is relatively more easy to micromanage with R- (right now), but just because you can micromanage it (a little more, a little less) with pressure-release doesn’t make it more real, natural or artsy.
Most people seem to think that trick training, clicker training and positive reinforcement are exactly the same, so let me give you a short and sweet explanation about these and other related terms.
An animal training method based on behavioral psychology that relies on marking desirable behavior with the use of a bridge (often a significant word like “Yes!” or a click with a clicker). The marker is called a bridging stimulus (bridge for short) because it bridges the time lag between when the behaviour occurs and it is possible to deliver a primary desirable reinforcer such as food. Once a bridge is established, it is a very useful communicative tool to tell the animal when they’re doing the right thing.
Trick training is simply using clicker training to teach tricks to horses. It is seen as a discipline most people practice for fun, alongside their normal training. The term is also commonly used to describe a lesser form of training (“That isn’t [real]/[art], it’s just a trick..”)
Most people consider tricks to be behaviors that have no practical purpose other than for entertainment. They tend to be things done for the amusement of people rather than for the benefit of the horse – although there can be beneficial side effects of teaching tricks when done well (they make rescue horses more appealing to adopters for example). They CAN in fact be fun to horses. This depends on how it was taught, how it is being reinforced, if and how much stress (physical, emotional or mental) it puts on the horse, etcetera.
Tricks are often seen as a lesser form of taught behaviours because they often don’t serve a practical purpose and don’t always seem to have a “dimmer switch” (asking a little more, a little less.), although this can be done through microshaping.
To a horse, all behaviours are the same. A horse can feel better or worse about certain behaviours asked because of the way they were taught for example, but the horse doesn’t categorize behaviours into husbandry, tricks, and gymnastic work like we do. Not saying horses aren’t smart! They can recognize the tiniest signs because they have consistently predicted the same thing in the past. This is why a horse might run off when he sees you coming with a bitted bridle, but happily comes up to you when you are carrying a brightly colored halter you use for trick training. They can recognize, associate and prefer things, but they don’t actively realize what are tricks, and what is work.
Using one or more types of aversive stimulus (aversive for short and often called pressure in ‘Natural’ Horsemanship terms or conventional aids in traditional, classical, western and all other forms of horse training) to cause the horse to perform a behaviour to escape or avoid the aversive, and then either marking the moment the horse performs the desired behaviour and giving a food treat, or just giving a food treat after the behaviour has been performed.
This however causes a lot of conflict and stress for the horse as well, often expressed through pinned ears, dropping or even erecting, swishing the tail, a tight face and hard eyes, and very excited movements. Another misleading term for ‘mixed training’ is ‘balanced training’, meaning the trainer has found a balance between the two reinforcing quadrants. Balance is a relative and often misused word; I could also state that I am balanced because I decided to punch 2 people in the face every day in stead of 4. Of course, punching no one is possible but there are people out there punching 4 or even more people every day! It’s all about finding balance. (People who talk like these like to call everyone else extremists)
This is a scientific term, not a method. If a behaviour is maintained or strengthened because it results in escape or avoidance of a stimulus, the behaviour is said to have been negatively reinforced – the negative word meaning subtraction or removal as in mathematics. It is also true that behaviour is reinforced if it results in reduction in aversive strength even if the aversive is not totally turned off. The relief the horse then feels is reinforcing, but is not considered a reward. Negative reinforcement is applied worldwide in the form of pressure-release techniques and is the underlying principle for all ‘Natural’ Horsemanship and Traditional training methods.
This is also a scientific term, and not a method. If a behaviours increases in frequency or strength as a result of the addition of a stimulus as an immediate consequence, it is said to have been positively reinforced.
Made up and misleading term for mixed training. Some trainers claim that using an aversive stimulus (or a conditioned one) to produce behaviour and then marking and adding an appetitive stimulus such as food can result in a balanced “neutral” reinforcement. This is incorrect and not backed up by science. Horses either worked (more) to avoid or gain something. It is also worth adding that a person can become a conditioned aversive to a horse because the person has the potential to act in a way that the horse finds aversive, either because they or another person has done so in the past or because they have associated themselves with other tools they have used to make their own body language gestures or vocal signals aversive to the horse. And that this threat potential of the person can persist even when they are no longer holding such a tool.
POSITIVE REINFORCEMENT MINDED TRAINING
This type of training is actually more of a lifestyle because it includes so much more than a training technique. It consists of methods, a mindset, and a lot of ethical and science based principles. Positive reinforcement trainers with this mindset, strive to put the feelings of the horse first over their own ego, pleasure and pride and you will tend to see them using positive reinforcement to train behaviours that are functional and empowering for the horse.
When it comes to priorities, this mindset leads people to focus on altering the environment in which the horse lives to influence his wellbeing and behaviour and on training behaviours that are useful for the stress-free management and longevity of the horse.

Now, before you start yelling at me: I am sure you were quite happy with the twitch in that emergency you had with your horse once. It might be necessary as an ABSOLUTE last resort. I’m just pretty sure most people don’t know that you’re supposed to look for alternatives before you head for that last resort. Let’s be honest, people seem to just twitch for anything the horse might resist, without even thinking they might be able to train. Clipping, mane pulling (yes, just substitute one pain for another), shoeing, mane plaiting…
When it comes to twitching horses, it seems little is known, a lot of assumed and common sense is ignored altogether. The most probable theory is that the pressure on one of the most sensitive parts of the horse causes the horse to release endorphins.
Endorphins get released in numerous situations. Exercise, sex, eating spicey food, eating comfort food, eating ginseng, love, having a laugh, sunbathing, smiling, sudden rushes of adrenaline and -oh!- severe pain. Now, unless you feed curry to your horse right before using a twitch, I’d say pain is what causes the release of endorphins. Not right away, mind you! It takes several moments for the numbness to kick in. Think of stubbing your pinky toe. It has to hurt before the painkillers start working. “The twitch is believed to work through the mediation of beta-endorphins, but there is little doubt that it works because it involves pain (webster 1994). The heart rate of horses when twitched undergoes a transient increase (Morris, 1988) before returning to baseline values. ”
We asked a pain expert what she thought. Here is what she said:
“My thoughts are that subjecting an animal to targeted acute pain will promote the release of a bunch of chemicals/ neurotransmitters. This would be very distracting as it is so aversive, and the animal would protectively immobilise itself in order to avoid more intense pain/ damage (a bit like an animal in a trap). Theoretically these pain chemicals could spread through the body & affect the “pain gate” & would help reduce pain in other areas of the body.”
Most studies seemed to measure the stress the horse was experiencing by looking for stress indicators on the outside , but a study with donkeys and another study with several stallions and geldings (horses) revealed cortisol levels were increasing (more than endorphins!). The animal is in a state of behavioural suppression.
Head shyness and fleeing reactions to seeing a twitch a second time also indicate a negative association with the tool. Stereotypies also release endorphins, so should we just keep horses locked up in solitary, barren environment? It helps reduce suffering but there must be suffering to start with. Animals (and humans) develop tolerance to opiods including morphine, so need increasingly high doses to have an effect. And horses with stereotypies tend to release endorphins by performing the behaviours.. and twitches are less effective with them. So we can tentatively conclude that horses develop tolerance to their own endogenous opiods, needing more in order to get the same effect… so over time, a twitch will become less effective if used regularly. It is also often advised to not use twitches for longer than 12-15 minutes since, in many cases, the effectiveness of the twitch tends to wane after this period, possibly because of neurotransmitter depletion at the level of synapses in the opioid pathways. In addition, there are reports of horses suddenly striking with their forelegs during twitching.
