McGreevy on Operant Conditioning

This post is part of the McGreevy seminar series. Click here for the index.

 

Please note: This article assumes some prior knowledge of operant or instrumental conditioning, as it mostly focuses on McGreevy’s comments on operant and instrumental conditioning, rather than on explaining these terms itself. If you are lacking a comprehensive understanding of Operant Conditioning, then I suggest this page from Crystal at Reactive Champion blog.  If you already have some idea of operant conditioning, come on in.  This may be confusing, but we can only hope it may add to your understanding.

Operant conditioning, also called instrumental conditioning, is when the animal’s voluntary response is instrumental (i.e. important) in establishing the consequence (i.e. reinforcement or punishment).  (By voluntary, we mean responses that the animal has control over.  Involuntary would be things like salivating or growing hair.)

McGreevy used the diagram below to consider operant conditioning.

Here, the ‘x’ marks the spot of neutral stimuli that does not modify behaviours.  That is, a neutral experience.  From here, stimuli can either be reinforcing and increase the probability of behaviours, or they can be punishing, and decrease the animal’s responses in question.  The purple arrows indicate negative punishment (-P) and negative reinforcement (-R).  Negative punishments use the removal of attractive stimuli to make a response less probable.  Negative reinforcements uses the removal of adverse stimuli to make a response more probable.

McGreevy on A Modern Dog’s Life

This post is part of the McGreevy seminar series. Click here for the index.

 

McGreevy spoke about some of the demands dogs face in the current era, and explained that these issues are considered in more detail in his book A Modern Dog’s Life.

Basically, McGreevy asks us to appeal to the types of things dogs have to ‘put up with’ in the modern world.  The difficulties of dogs in the 21st century are far different to those of their ancestors.

Dogs have to deal with physical barriers in the modern era.

We have co-evolved, so in a way, we exploit each other, and dogs do cope quite well considering what we do to them.  For example:

Dogs are expected to get in and out of cars. The car is a noisy machine that suddenly transports dogs to a entirely different destination, in which dogs are then expected to cope with.

Dogs experience man-made boundaries and barriers. There are no doors or fences ‘in the wild’.

Dogs walk on man-made surfaces.

Dogs tolerate us touching them in ways other dogs never would.  We touch dogs around the neck. We stare them in the eyes. We hug them.

 

Clearly, there are hosts of stresses for ‘modern dogs’ that need to be considered in studying dogs.  He appealed for applied ethology – ethology that considers human-dog interactions.

 

This train of thought made me think about the kind of stresses I place on my dogs, without even realising it.  I expect my dogs to tolerate me exiting through a door – barriers like this, and ‘pack members’ leaving like this, is quite unnatural.  (For the most part) they don’t attack brooms, the poop-scoop, or other items, even though they are normally displeased about their presence.  I clip their nails!  I keep a bird in a cage that they have to ignore.  All really unnatural behaviours that our dogs, by miracle of being dogs, have learnt to deal with.

What have your dogs learnt to deal with, that their ancestors surely didn’t?

McGreevy’s Thoughts on Dog Breeding

This post is part of the McGreevy seminar series. Click here for the index.

 

Throughout Paul McGreevy’s two day seminar, he expressed a number of opinions regarding dog breeding. Being a dog breeder myself, I anticipate I paid particular heed to his comments.  I find that, in the current climate of dog rescue and puppy farms, dog breeders are constantly under scrutiny and, in general, I find myself a little defensive to conversations surrounding dog breeding.

However, McGreevy had some very interesting and thought-provoking ideas surrounding dog breeding, and he presented them in a very amenable way.  That is: McGreevy didn’t breeder bash!  He approached matters surround breeding dogs in a matter-of-fact way.  Indeed, he spent more time blaming the system of dog breeding (i.e. breeding purebred dogs to a standard) for the problems in dogs today than critiquing breeders themselves.  Fundamentally, McGreevy believes that the system for breeding dogs need to change in order to emphasise the health and temperament of dogs, and not their physical appearances.

Domestication and dog breeds

Domestication and selective breeding have changed dogs from their wolf ancestors.  For example, dog skulls have changed a great deal from the skull of a wolf, and there is also much variation between dog breeds.  Not surprisingly, the brains of dogs have changed too, with a wolf brain weighing three times as much as a dog brain.  Considering that the dog’s brain is part of its central nverous system, it is reasonable to assume that there may be implications for the dog’s entire nervous system.  McGreevy said, “We are only just beginning to learn what we’ve done.”

One thing is for sure: We don’t have a wolf in our lounge room.

In times gone by, breeding dogs were selected on the ability to perform tasks, such as herding, retrieving, carting, or any other purpose.  These days, selection is mostly based on conformation, and emphasis is being place on ‘beauty’ traits such as coat and colouration instead of structure.  McGreevy believes that this current system ineffective, as 150 years of breeding dogs ‘to standard’ has resulted in a host of inherited disorders.  Considering this, McGreevy believes that the dog breeding system needs to change.

 

Current dog breeding practices are cruel

McGreevy asserted that inherited disorders are a form of cruelty.  He also put forward that, considering that the main reason dogs are euthanised in shelters is due to their temperament, breeding for good temperaments is imperative.  Neither of these traits are overly considered in the current breeding system.

McGreevy believes that breed standards often are in contradiction to animal welfare.  He used the British Bulldog as an example.  He criticised the standard for asking for a head that is “the larger the better”, while at the same time calling for a narrow pelvis – an obvious problem for the whelping abilities of the breed.  Furthermore some of the points in the standard are actually unhealthy (for example, loose skin in Shar Pei has been found to correlate with joint problems, and the skull shape of a dog influences its vision).  In McGreevy’s opinion, dog breed standards have been written in a manner that is sometimes contradictory to dog well being.

Pitbull Hysteria, Australia

Recently, a girl in Victoria was killed by a dog identified as a pitbull cross.  A terribly tragic event, which has ramifications that are simply frightening for the dog community.

The Victorian premier has begun implementing legislative changes, which ultimately put all ‘pit bull type’ dogs at risk of being destroyed. (Another news article describing these changes available here.)

I do not want to waste time describing all the reasons these changes are misguided. I am writing this post to motivate action. Please, dog owners, do something!!  If this is implemented in Victoria, many dogs are at risk of euthanasia.  This also sets a precedent for other states.

I have included below a number of letters I have sent to parliamentary figures. Feel free to modify these letters and make them your own, or even send them as they are. Continue reading

“A Puppy Called Aero”

This is a brief interlude to my Paul McGreevy Seminars notes to happily announce my latest guest post, on A Mom’s View of ADHD… When I am neither a mum let alone a mum of an ADHD child!

However, I read Liam Creed’s book A Puppy Called Aero, mostly because it was a book about a dog, and realised how relevant it is for anyone with an interest or investment in ADHD children.  It is a lovely story of the human-animal bond, and also examines the importance of assistance dogs.

So please visit and read my book review: A Puppy Called Aero – How a Labrador saved a boy with ADHD.

More thoughts on the Paul McGreevy seminars to return soon!
