How Dogs Learn
CLASSICAL CONDITIONINGAlso known as Pavlovian, Associative and Respondent
OPERANT CONDITIONING What we know as “training”
![Page 6: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/6.jpg)
How Dogs Learn
CLASSICAL CONDITIONING
• Pavlov’s Dogs
• Relates to reflexes not to voluntary behaviors
• Happening all the time
• Clicker and food is a classical association
• Teaching a cue is a classical association
![Page 7: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/7.jpg)
How Dogs LearnOPERANT CONDITIONING
Definition (from How Dog’s Learn Burch & Bailey, 1999): “The part of science of behavior that explains the functional relationshipbetween environmental events and behavior. It is a key component in explaining how all organisms (including dogs) learn.” In simpleterms what happens in the environmentwill affect what a dog will do in the future. If a dog receives a cookie for sitting he will be more likely to sit again. If a bee stings a dog when he sits he is less likely to sit.

How Dogs LearnOPERANT CONDITIONING
REINFORCEMENT:• Strengthens behaviors• Is anything that will increase the likelihood of
a behavior to happen in the future• To be effective it should closely follow the
behavior so an association is made
![Page 10: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/10.jpg)

PUNISHMENT:• Weakens behaviors• Punishment decreases the likelihood of a
behavior to be repeated in the future• To be effective it should closely follow the
behavior• Has potential fallout; fear, anxiety

How Dogs Learn
REINFORCEMENT in dog trainingStrengthens behaviors
• Positive Reinforcement Add good As perceived by the dog
• Negative Reinforcement Remove badAs perceived by the dog
![Page 12: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/12.jpg)
How Dogs Learn
REINFORCEMENT in dog training
Positive Reinforcement
Add good - As perceived by the dog
Examples: Food, toys, exercise,
play & petting (not all dogs)
![Page 13: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/13.jpg)
How Dogs Learn
REINFORCEMENT in dog training
Negative Reinforcement
Remove bad, As perceivedby the dog
Examples: Stop pulling on a leash, stop electronic collar; spray or shock, stop
ear pinch

How Dogs LearnREINFORCEMENT in dog training
Positive & Negative Reinforcement Primary An Unconditioned Reinforcer. A primary reinforcer will increase the likelihood that a behavior will be repeated in the future when presented immediately following a behavior. Related to basic needs, food, drink, some touch.
Secondary A Conditioned Reinforcer. It is something that by itself does not mean anything to the dog. But when paired with a primary reinforcer the secondary will then strengthen behaviors. For dogs these can include, praise, clicker, petting, verbal reprimand or sound. This pairing is classical conditioning.
REINFORCEMENT INCREASES BEHAVIOR
![Page 16: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/16.jpg)
How Dogs Learn
Punishment in dog training: Punishment decreases behavior
• Positive Punishmentadd something bad
• Negative Punishmenttake away something good
The good or bad must be the dogs perception
![Page 17: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/17.jpg)
How Dogs Learn
Punishment in dog training:
Positive PunishmentAdd something thing bad
Examples: electric shock, leash correction, spray bottle or collar, throwing objects, hitting
![Page 18: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/18.jpg)
How Dogs Learn
Punishment in dog training:
Negative Punishment
Remove something good
Examples: Time out in crate = removes you or the fun, Take dog away from fun event
such as agility run for broken stay
![Page 19: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/19.jpg)

How Dogs Learn
Punishment in dog training:
Positive & Negative Punishment
Primary An Unconditioned Punisher. The dog does not need prior experience for it to be perceived as a punisher. Extreme heat or cold, shock, pinch, citronella spray, hitting are all examples of primary
Secondary A Conditioned Punisher. It is something that by itself does not mean anything to the dog. But when paired with a primary punisher the secondary will then weaken behaviors. Verbal or sound. This pairing is classical conditioning.
PUNISHMENT DECREASES BEHAVIORBut there is possible increased anxiety and fallout
![Page 21: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/21.jpg)

How Dogs Learn
finally…The ABC's of learning
A= Antecedent or A Signal (cue)
B= Behavior (action)
C= Consequence (payoff)
Good Consequence = Reinforcement Bad Consequence = Punishment
![Page 23: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/23.jpg)
How Dogs Learn
The ABC's of learning
A= Antecedent or A SignalCues
Verbal: words, soundsVisual: hand, body, motionEnvironmental: agility obstacles
Think about the dog you have when making choices for cues; visual or sound stimulation stronger?
![Page 24: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/24.jpg)
How Dogs Learn
The ABC's of learning
B= BehaviorAction or duration of non actionVoluntary action: sit, down, lift pawNon action: stay in position
Behaviors that are offered by the animal appear to be learned more
quickly vs. guiding or continuous luring
![Page 25: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/25.jpg)
How Dogs Learn
The ABC's of learning
C= Consequence
Payoff
Good Consequence = Reinforcement, R+Increases likelihood of behavior
Bad Consequence = Punishment
Decreases likelihood of behavior
![Page 26: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/26.jpg)
How Dogs LearnOnce learned, Good Consequences =
Behaviors Happen:
Human Example: A = Antecedent (cue): Alarm goes off, ugh…
B = Behavior: Get up and go to workC = Consequence: Paycheck, yahoo!
Canine Example:A = Antecedent (cue): Verbal “Sit”
B = Behavior: Dog puts butt on the floorC = Consequence: Dog gets to go out to play!
![Page 27: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/27.jpg)
How Dogs Learn
“Natural” Progression of A-B-C
Begging:
A - Owner eating at table
B - Dog Begs
C - Owner gives a piece of food
Think the begging will be repeated?!
![Page 28: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/28.jpg)
How Dogs Learn
Training Steps: A new alphabet
B-C-A
Maximizes learning & the quality of the final behavior performance
B = Behavior: Get itC = Consequence: Give itA = Antecedent or A Signal: Add after behavior is strong, insert before behavior
![Page 29: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/29.jpg)
How Dogs Learn
Training Steps
B = Behavior: Get the dog to perform the desired behavior
Capture: R+ dog doing behavior
Shape: R+ parts of the behavior working closer to the end behavior
Lure: Use of food or toy as a guide to where you want the dog then R+
![Page 30: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/30.jpg)
How Dogs Learn
Training StepsC = Consequence:
R+
When the dog does the behavior- Capturing
When the dog does part of the behavior- Shaping
As the dog follows the food into position or partial position - Luring
![Page 31: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/31.jpg)
How Dogs Learn
Training Steps
A = Antecedent or Cue: Add after the dog becomes good at the behavior, cue will pair with the end behavior performance (usually better than beginning)
Cue is presented just before the dog does the behavior = Classical Conditioning
R+ as usual
![Page 32: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/32.jpg)
How Dogs Learn
EXAMPLE OF CAPTURING – SHAPING – LURING
Down – Capture: Sit in a small quiet room R+ as dog lies down on his own
Shape: R+ as dog lowers head, then bends elbows, then lowers back end etc.
Lure: Guide dog into position with food or toy
desired by the dog, R+ in position
![Page 33: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/33.jpg)

How Dogs Learn
Emotions & Motivation impact Learning
Take all we have studied so far into consideration…EmotionsHardwiring - MotivationPast ExperiencesLack of Experiences
Keep in mind all of this and the immediate environment have a big influence on a learners ability to learn

Learning by observation
![Page 37: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/37.jpg)
Local Enhancement
Emery, N. and N. Clayton (2005). Animal Cognition. The Behavior of Animals: mechanisms, function and evolution. J. Bolhuis and L. Giraldeau. London, Blackwell Publishing.
Attraction to others indirectly leads to learning about presence of an object
“Just chillin...”
“I wonder what Fred is up to... Hmm...
not much...Whoa, look at that
cookie jar”Dem. Obs.
![Page 38: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/38.jpg)
Stimulus Enhancement
Emery, N. and N. Clayton (2005). Animal Cognition. The Behavior of Animals: mechanisms, function and evolution. J. Bolhuis and L. Giraldeau. London, Blackwell Publishing.
Learns about presence of object by observing the interaction of another
animal with the object
“Hmmm, what is he playing with..”
“Bug off, this is mine...” Dem. Obs.
![Page 39: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/39.jpg)
Observational Conditioning
Emery, N. and N. Clayton (2005). Animal Cognition. The Behavior of Animals: mechanisms, function and evolution. J. Bolhuis and L. Giraldeau. London, Blackwell Publishing.
Emotional response to an object based on observing another animal’s response
“Hmmm, snakes must be bad...
Eeek...”
“Eeek, a snake...”Dem. Obs.
![Page 40: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/40.jpg)
Things to note...
• The other animal is just doing their thing, their role as “demonstrator/teacher” is purely a side-effect.
• Think of wolf pups following mom & dad
• Their presence/interaction/response provides, in effect, a focus of attention that simplifies the learning problem for the observer.
• Associative learning is probably sufficient given this scaffolding
![Page 41: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/41.jpg)
Goal Emulation...
Emery, N. and N. Clayton (2005). Animal Cognition. The Behavior of Animals: mechanisms, function and evolution. J. Bolhuis and L. Giraldeau. London, Blackwell Publishing.
a) Observe another animal achieve a goal by performing a specific action
b) Achieve same goal but use a different action
The difference in this case is that the person and the monkey orient the rake differently
![Page 42: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/42.jpg)
Imitation...
Emery, N. and N. Clayton (2005). Animal Cognition. The Behavior of Animals: mechanisms, function and evolution. J. Bolhuis and L. Giraldeau. London, Blackwell Publishing.
a) Observe another animal achieve a goal by performing a specific & novel sequence of actions
This type of observational learning seems to occur rarely in other species than humans
b) Achieve same goal by performing the same specific & novel sequence of actions
![Page 43: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/43.jpg)

Why?
• Why are goal emulation and imitation apparently so rare in species other than humans and maybe other apes...
• May require a type of cognitive machinery (little or big) not found in other species...
• The cost/benefit may low (i.e., the common forms work well enough given built-in behavioral structure & context)
• Just haven’t looked hard enough...
![Page 46: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/46.jpg)
What do our slacker friends do?
• Common forms of observational learning...
• Local enhancement
• Stimulus enhancement
• Observational conditioning
• Less common forms
• Goal emulation (???)

Big idea...
• Test for evidence of observational learning in Miniature Dachshund pups of varying ages...
• Had some pups watch another pup retrieve ‘inaccessible’ food by pulling on a string that was attached to the food
• Compared time it took naive pups to retrieve food by pulling on string with the time it took pups who had experience watching other pups do it.
![Page 49: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/49.jpg)
More details...
• 4 litters of doxie pups, 1 from each litter chosen as demonstrator for rest of littermates
• 3 days of acclimatization (???)
• 5 trials per day in which demonstrator learned how to retrieve food, and observers watched
• After 15 trials, observers were given chance to perform task
![Page 50: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/50.jpg)
Results from Adler

Results from Adler...
• The observers generally retrieved the food substantially faster on the first three trials than their demonstrator
• Particularly strong effect on 60 and 38 day-old litters
• Evidence that they benefited from watching demonstrator
![Page 52: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/52.jpg)
Stimulus enhancement?
• “In some cases the observer ran to pull the ribbon as soon as it was made available, with frantic activity continuing although the food was already within reach. Persistence in working and skill in manipulating the ribbon had to be learned by practice.”
![Page 53: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/53.jpg)

The big idea...
• “Pups with extended maternal care which were allowed to observe their trained mothers locating and retrieving a sachet of narcotics between the ages of 6 and 12 weeks performed the same task significantly better than non-exposed pups when tested at the age of 6 months, without further reinforcement during the interim period.”
![Page 55: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/55.jpg)
Setup cont...
• Between 6 and 8 weeks, Group 4 pups got to observe mom retrieve drugs a total of 6 times.
• Between 9 and 12 weeks, Group 4 pups got to observe mom retrieve drugs and seem to have been able to sniff drug sachet while in mom’s mouth.
• No other group got to observe Mom performing task or had any exposure to drugs...
untrained mom
trained mom
removed at 6 weeks
group 1 group 3
stay with mom until 12 weeks
group 2 group 4

Tested performance at 6 months
• At 6 months dogs tested for performance, ranked on a scale 1 to 10 with regards to...
• interest in task, manner in which approached sachet, & way it searched and found sachet
• if found, how the dog picked it up & whether the dog carried it back to handler
• Subjective, but testers did not know background of pups...
![Page 57: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/57.jpg)
Results...
• Pups who observed mom retrieving sachet & had opportunity to sniff mom’s mouth did better...
• Seems clear that observational learning occurred, but we don’t know the relative importance of...
• observing mom perform task, and/or
• association of smelling sachet in mom’s mouth, and/or

More thoughts...
• Simple but Reliable Rule:
• Stuff that you smell in mom’s mouth must be good, and thus, worth learning, remembering & finding...
• I sure wish I knew
• how important observing the act of retrieval was...
• does it matter if it is mom?

Social learning: selective imitation?
![Page 60: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/60.jpg)
Three simple types of social learning
Just because its simple, doesn’t make it any less useful
Local enhancement: “I think I’ll hang out with Harry. Hmmm, what’s that”
Stimulus enhancement: “Hey what’s Harry fooling with. That looks tasty”
Observational Conditioning: “Yikes, what is Harry reacting to, I guess I should be scared too”
![Page 61: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/61.jpg)
These previous types of social learning can be explained via associative learning, but...
• Josep Call postulates 2 alternative mechanisms...
• The ‘cue-based’ approach. The animal learns to respond to a given stimulus in a given way, or learns to predict a given future stimulus based on observing another given stimulus.
• All about correlation, no mental model of causation, and hence little or no ability to generalize.
• The ‘knowledge-based’ approach. Here the animal extracts functional features associated with the stimulus, and builds a functional model of greater or lessor complexity that it then uses to guide its choice of behavior
• To the extent that the functional model accurately captures causation, it provides a mechanism to generalize. Call, J. (2001). "Chimpanzee social cognition." Trends in Cognitive Science 5(9): 388-
393.

Range, F., Z. Viranyi, et al. (2007). "Selective Imitation in Domestic Dogs." Current Biology 17: 1-5.
Selective imitation
• Dogs trained to pull a ring for food via mouth and paw
• Control dogs given opportunity to solve this problem on their own. 85% used their mouth to pull on the rod.
• Experimental dogs watched 8 trials of a demonstrator using their paw to push down on the rod.
• One group, demonstrator has ball in mouth
• Other group, demonstrator doesn’t have a ball in mouth

Possible explanations...
• The dogs really are making the kinds of inferences that I have described on the previous pages...
• If so, this is both quite remarkable and quite unexpected
• Is there some confounding factor that isn’t apparent to us that makes it appear as if the dog is making an inference when in fact they are responding to something else in the experimental set-up.
• In either case, it is a fascinating question to ponder...
![Page 69: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/69.jpg)

The big idea...
• “...a companion dog showing intentions of predatory behaviour stimulates predatory chase in another dog, while a non-chasing companion has limited influence on this...”
• That is, predatory behavior in one dog may trigger predatory behavior in another,
• but absence of predatory behavior did not have a calming influence
![Page 71: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/71.jpg)
The set-up
• 20 Norwegian Elkhounds (11 males, 9 females), split into 2 age groups: less than 2.5 years old, and older than 2.5 years old.
• 2 demonstrators: a chaser (a BC) and a non-chaser (a Hamilton Stoever)
• a priori tendency of test dogs to chase not tested but general behavior described via questionnaire
![Page 72: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/72.jpg)
Just so you know...
![Page 73: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/73.jpg)
Test...
• Test dog and demonstrator allowed time to greet.
• Test dog put in pasture with 5 sheep and demonstrator
• After initial reaction of test dog recorded, if chasing demonstrator, then cued to chase sheep
• Behavior of test dog recorded over 5 minutes
• First non-chase trial, 3 days later chase trial
![Page 74: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/74.jpg)
Results: Norwegian Elkhounds seem awfully predisposed to chase sheep
60% of dogs attacked sheep with non-
chasing dog, 100% on 2nd trial with
chasing dog
Attack severity greater, and attack latency shorter on
2nd trial with chasing dog

Discussion
• “a companion dog that shows intentions of predatory behavior stimulates predatory chase in another dog, while a non-chasing companion has a limited influence on the predatory behavior of the test dog”
• “regarded as cases of social facilitation, originally defined as the performance of a behavior pattern as a consequence of the performance of the same behavior by other individuals”
• “the border collie did not lead the attack, but somehow influenced the attack motivation in test dogs. The typical constant interest towards sheep shown by border collies, i.e. showing eye display... and occasionally showing short stalk sequences may have stimulated or accelerated predatory chase in test dogs. However, the Elkhounds never followed the Border collie’s withdrawal or submissive behavior”
![Page 77: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/77.jpg)
Social Facilitation
• This is a kind of SBRE rule...
• “perform predatory behaviors toward animals that social partners are showing predatory behavior towards”
• rely on the assumption that the others know what they are doing...
• don’t need to totally discover on own which animals are appropriate targets for predatory behavior
![Page 78: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/78.jpg)
Social Facilitation...
My sense is that there are a ton of examples of this in real world
dog behavior...

Big idea...
• Dogs are conservative, they go with what worked in the past.
• what happens when what worked before doesn’t work any more?
• Observed behavior of human demonstrator can influence dog’s choice of behavior...
• what are they observing?

Big idea...
• Previous success biases a dog’s choice of action even when an ‘obviously better’ choice of action is made available...
• dogs are conservative
• Dogs could use actions of a human demonstrator to guide their choice of action
![Page 83: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/83.jpg)

using door, which is subsequently
unavailable

Dogs had a tough time
getting over the fact that the door was closed in the absence of a demonstrator
![Page 86: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/86.jpg)
Experiment two...
• Dogs had varying previous experience with detouring
• 3 detour demonstration trial (dog gets to do detour)
• 1 detour demonstration (dog gets to do detour)
• Test trials with door open
• Trial 1 door opened while eyes covered
• Trials 2 and 3 dog sees food placed through open door
![Page 87: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/87.jpg)

detouring persisted in detouring even when door was available

3 demonstrations
Dogs with a single demonstration were more focused on the door than those who
had three demonstrations
1 demonstration

Discussion
• Dogs tended to use first strategy that worked and would persist in using strategy even when a better one came along
• The more experience, the harder it was to change
• Socially acquired experiences given up slowly*
• Dogs did take advantage of watching a demonstrator with respect to taking a detour.
![Page 90: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/90.jpg)
Discussion
• “Both of our experiments revealed the complex interaction between asocial (individual) and social learning that must be taken into account to understand how learning abilities in general contribute to increased fitness in animals. In experiment 1 social learning was advantageous in a situation where experience constrained the dogs’ behaviour. On the other hand in experiment 2, dogs facing a novel situation and exposed to socially provided information regarding access to the target were reluctant to change their behaviour, showing a preference for the more conservative (and socially learned) behaviour.”
![Page 91: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/91.jpg)
Thoughts...
• Nice demonstration of observational learning and of conservative, to a fault, decision-making on the part of the dogs...
• I am less convinced that the way the learning occurred (social) meant that it persisted longer. The observation is conflated with the actual experience.
• They make a lot of this in the paper...
![Page 92: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/92.jpg)
And yes...
• There may be an SBRE rule or two lurking here as well...
• go with what you know
• Is demonstration example of stimulus enhancement (end of fence) or local enhancement (places to wander)?
![Page 93: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/93.jpg)

Masters of understatement
• “There has been one notable failure using this method, this involved a lar gibbon who attacked the model-rival during training sessions; this probably occurred due to the aggressive and territorial nature of this species”
• Lesson: know your animal, and don’t trust your advisor...
![Page 96: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/96.jpg)
Big idea of model-rival...
• Animal observes trainer and a “model-rival”
• Trainer: “Can you see the SOCKS?” & hands toy to M-R
• Model-Rival: “Yes I can, thank-you for the SOCKS” & hands toy to trainer
• repeat...
• M/R is modeling desired behavior and rival for attention and/or possession of object.
![Page 97: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/97.jpg)
Big idea of model-rival
• “fetch Mr. Squirrel” & receive a treat
• Q: in dog’s mind does the label “Mr. Squirrel” refer to the object or to the act of retrieving it and getting a cookie?
• A: who knows, but Pepperberg argues in traditional training, it is the latter, because the reward is extrinsic. This makes the label context-specific (i.e., tied to the specific action)
![Page 98: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/98.jpg)
Big idea in model-rival
• In model-rival training, the animal’s reward for successfully performing the task is the object itself. The reward is intrinsic...
• Pepperberg argues that this makes it more likely that the label becomes associated with the object, and thus can be used in other contexts...
• “how many Mr. Squirrels are there?”
![Page 99: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/99.jpg)
Big idea of model-rival...
• To keep dog’s interest, trainer & model-rival
• “speak in a highly animated way” [lots of motion??]
• “look at target object at all times”, but
• “voice direction and body postures directed toward dog”
• After 2 minutes, dog gets to try...
![Page 100: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/100.jpg)
The test...
• After 2 minute training session...
• Trial
• Target object part of a group of 3 objects
• Dog told to “Go get the SOCKS”
• Trial ends when dog retrieves correct item, time noted.
• Note: order of retrieval doesn’t directly matter!!!

Thoughts...
• Very cool example of using stimulus enhancement & maybe local enhancement to possibly help dog make association between label and object.
• interesting that dogs may be able to make this association
• Raises the whole question of intrinsic vs. extrinsic rewards
• Great to be exploring alternative approaches to training
![Page 103: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/103.jpg)
Thoughts from Mr. Grinch...• We don’t know whether differences in training technique had any
impact on accuracy since this isn’t reported...
• why is article so silent on this point?
• What evidence is there for the following statement?
• “The m-r method resulted in the dog knowing what the object’s name was, whereas the operant method only resulted in the dogs knowing that retrieving the object results in a food reward”
![Page 104: The Cognitive Dog:Savant or Slacker](https://reader035.fdocuments.net/reader035/viewer/2022062422/5681354a550346895d9ca7f8/html5/thumbnails/104.jpg)
Thoughts from Mr. SBRE
• Is there a Shallow But Reliable Enough Rule, or two, lurking here?
• “Stuff being handled by social partners must be good, and thus worth learning, remembering & finding...”
• “Pay attention to what social partners handle”
