Operant and Classical
Conditioning
Operant conditioning is a defined set of
principles, developed in the 1930’s by a behavioural scientist called B.F.
Skinner. The theory says we can make things happen, either good or bad, by
choosing behaviours that are either rewarded or punished. We use the 4 methods
Positive Reinforcement, Positive Punishment, Negative Reinforcement and
Negative Punishment and where the dog acts upon the environment. Dogs will not
generalise well, here, and need to be trained in all different environments in
order to fully understand what is required. Once they have learned the
behaviour, in the front room, we then need to train that behaviour in the
garden, then in the park, and so on, until the behaviour has become
generalised. E.g. the dog learns that they can make good things happen by
offering the sitting behaviour. Next the dog needs to learn that those good
things still happen if the sitting behaviour is performed elsewhere. We are
using the Positive reinforcement quadrant here to teach the dog that sit is the
behaviour we want, and we want it, to cue, in all environments.
With Classical Conditioning, we are not
necessarily looking to train a behaviour, yet looking for an emotional response
from our dog. Often our dogs have learnt
these responses from a single incident, and thus these become generalised very
quickly. Behaviours that involve a strong emotional response where the
environment acts upon the dog are classically conditioned. i.e. fear of thunder
and lightning or the fear of children after an incident involving a child
pulling his/her ears. Next time he/she see’s a child, they can generalise very
quickly and have an emotional response of fear towards children. On the other
hand, as with Pavlov’s dogs, the emotional response to the bell ringing was to
salivate at the prospect of food, and dogs who have had pleasant experiences
with children, soon generalise that all children are nice, and their emotional
response is one of happy thoughts and not fear.
When looking to apply operant conditioning or
classical conditioning when dealing with a dog’s problem, first we must define
the problem. Problems are often defined as problems for the owners and not for
the dogs. A dog that loves to greet us by jumping up, may have been rewarded
for this by a cuddle here and there, and yet now it has become a problem,
especially as the dog has grown bigger and stronger. Here we would teach the
dog a new behaviour (operant conditioning) as jumping up is not necessarily an
emotional response (classically conditioned) but a learnt one, probably through
reward.
We would in this case use positive reinforcement, and maybe, negative punishment to change the unwanted behaviour of jumping up to the desired one of sitting when you greet me.
When the dog jumps up we can turn away (negative
punishment) and when the dog puts all 4 feet on the floor, we reward that
behaviour (positive reinforcement) As we continue to do this exercise, the
unwanted behaviour will extinguish, and the desired behaviour increase.
Alternatively, if we do not want to use negative
punishment here, we can ask the dog for an incompatible behaviour to jumping up
(desensitisation of incompatible behaviours), a sit, and reward this desired
behaviour. Again the unwanted behaviour will eventually extinguish and the
desired behaviour increase.
If we were to encounter a dog who would bark at
another dog, due to an emotional response of fear (classically conditioned), we
could look to change the dogs emotional response using classical conditioning,
or a technique called counter conditioning.
For dogs to learn, we must ensure that they are in
the right state of mind, and a dog that is so fearful may not be able to learn,
as its emotions are such that it is not cognitive to learning. This happens if
we subject the dog to too much of the stimuli that causes the fear in the first
place. Some trainers will flood the dog here in an attempt to prove to the dog
that there is nothing to fear and subsequently change the dogs emotional
response and learn to be happier in the presence of other dogs. This method, in
my opinion, can also cause a dog to shut down and not be able to learn that
other dogs are nothing to be fearful of, or worse still lead to some aggression
towards the other dogs. If we ensure that the dog is in a clam state before we
introduce the stimuli, then this helps towards learning. We need to change the
dogs emotional response from fear by adding something nice in the presence of
the stimuli. We can use high quality treats to feed the dog, ensuring that our
dog is not overly stressed at each stage. We will keep the stimuli(other dog)
at a distance, where our dog is happily eating the treats, thus now pairing the
presence of another dog with something nice. We can move the stimuli closer
over a period of time or over different sessions, as our dog becomes more at
ease, subsequently classically conditioning the dog to enjoy the presence of
other dogs.
