Terminology.
Often someone posts something referencing operant conditioning, mostly “positive reinforcement”. But there is more to operant than that. It helps if everyone is on the same page when using technical language, but often it becomes obvious that the terminology is not well understood, so herein is a brief refresher course.
Back in the day a guy named Pavlov conducted an experiment involving food, dogs, and bells. Pairing a neutral stimulus (bell) with an unconditioned stimulus that causes salivation (food) results in salivating at the sound of a bell. This is Classical Conditioning. It’s also what you do when you “load the clicker” in clicker training. You pair the sound of the clicker with the food reward.
A guy named Skinner coined the term “Operant Conditioning” for the process of conditioning responses by means of reward or punishment. In Operant Conditioning the reinforcement or punishment follows the behaviour to either strengthen it (reinforcement) or discourage it (punishment).
Positive reinforcement typically is the “click/treat” method most people are familiar with, but the other “positive” is positive punishment, i.e. an unpleasant consequence that follows the behaviour to discourage its recurrence. This could be as mild as a disapproving word, or perhaps a dose of water from a spray bottle, but to be effective it needs to be something the animal would prefer to avoid, otherwise known as an aversive.
Negative reinforcement is the application of pressure of some sort, which is removed when the animal performs the required behaviour. This is how horses typically are trained….e.g. pressure from the rider’s legs is removed when the horse moves forward, pressure from the bit is removed or lessened when the horse turns or stops. Negative punishment is removing something the animal wants, as in walking away from a nippy puppy, thus denying your attention that he craves. This could also be crating as a “time out”, denying him his freedom. Withholding expected food or praise is another example.
But here is where it gets tricky. Sometimes we misinterpret what the dog finds salient. If the response to bad behaviour lands our dog in his crate, it is the dog who decides if this is in fact negative punishment. If he has misbehaved because he is fed up with our training session, being confined to his crate might actually be preferable to the training, thereby becoming a positive reinforcement of the misbehaviour, since we are no longer bugging him to perform.
The most important element of training is observation. You can do everything “correctly”, but if it isn’t working you need to figure out why and modify what you are doing. Often people are not reinforcing what they think they are reinforcing. Ultimately it is the animal who decides what is reinforcing and what is punishing, and their response tells you what you need to know.
You don’t have to be a clicker trainer to employ operant conditioning. Many people who didn’t know the jargon have been using the principles since well before Karen Pryor popularized clickers and “all positive” training. And you don’t need a clicker, either. A marker word will suffice when using positive reinforcement. A clicker is more precise, but in practice isn’t always easy to employ. But if we want to use operant terms when discussing training it’s useful to know the precise meaning of them. To reiterate, positive means adding something, negative means taking something away. Reinforcement means increasing the likelihood of the behaviour being repeated, punishment means decreasing the likelihood of the behaviour being repeated. Clear as mud?
