Learning Theory Flashcards
Pavlov
Classical Conditioning
Who created Classical Conditioning?
Pavlov
Watson
Behavior is based on responding to stimuli
Who did the Baby Albert experiment?
Watson
Who did the Baby Albert experiment?
Watson
Who developed the theory that all Classical Conditioning explains all behavioral psychology?
Watson
Who coined the Law of Effect?
Thorndike
What is the Law of Effect?
Consequences drive the strengthening or weakening of a behavior.
Who created Operant Conditioning?
Skinner
What is Operant Conditioning?
Stimulus > Action > Consequence
Using rewards or punishments to modify a behavior.
Skinner
What is the Premak Principle?
High probability behavior reinforces low probability behavior.
“Grandma’s Rule” Finish Veggies to get Ice Cream
What is Classical Counter Conditioning?
Changing a response to a stimulus.
When is Classical Counter Conditioning Used?
To change a fear response by pairing the frightening stimuli with food.
What does CER stand for?
Conditioned Emotional Response
What is desensitization?
Gradual exposure to stimuli while dog remains under threshold.
Learning associations between behaviors and consequences is…
Operant Conditioning
Operant Conditioning is founded on…
Thorndike’s Law of Effect
ABCs are an example of
Operant Conditioning
Behavior is strengthened
Reinforcement
Behavior is weakened
Punishment
+R
Positive Reinforcement
ADD to INCREASE
Good stuff happens, increasing behavior
-P
Negative Punishment
REMOVE to DECREASE
Good stuff stops, decreased behavior
+P
Positive Punishment
ADD to DECREASE
Bad stuff happens, decreases behavior
-R
Negative Reinforcement
REMOVE to INCREASE
Bad stuff stops, increases behavior
Positive
Add Stimulus
Negative
Remove Stimulus
Reinforcement
Increases Behavior
Punishment
Decreases Behavior
Punishment
Decreases Behavior
Primary Reinforcers
Food, Water, Sleep, Pleasure, Elimination, Sex
Secondary Reinforcer
Something paired with a primary reinforcer to gain value
Example:
Clicker = Food
New behavior should be rewarded with
High Value Rewards
Maintaining a behavior should be rewarded with
Lower value rewards or less frequency
CRF
Continuous Reinforcement Schedule
Reward after every single correct action is performed.
Good for teaching a new behavior.
Fixed Interval Reinforcement (FI)
Rewarding after a set and unchanging amount of TIME
Example: A treat after every 3 seconds of a sit-stay
Variable Interval Reinforcement (VI)
Changing, intermittent or unpredictable reinforcement for amount of TIME an action is performed.
Ping ponging. 3 seconds, 5 seconds, 4 seconds.
Fixed Ratio Reinforcement (FR)
Rewards given after a set NUMBER of repetitions of an action.
Example: Touch, touch, touch = treat. Treat given always after 3 touches.
Variable Ratio Reinforcement (VR)
Rewards given after an unpredictable or varying NUMBER of repetitions of an action.
Example: Treats after 2 touches, 4 touches, 3 touches
What Reinforcement Schedule is most resistant to extinction?
Variable Ratio Reinforcement
Example: Like a slot machine - people continue to pull the lever hoping for a jackpot even though most pulls give no reward.
What is the LEAST productive reinforcement schedule?
Fixed Interval is the least productive as it is most susceptible to extinction.
Kneeing the dog in the chest when he jumps is an example of
Positive Punishment
Spraying a dog with water when they bark is an example of
Positive Punishment
Coming to a stop when your dog is pulling on a leash is an example of
P-
Negative Punishment
Turning away from a jumping dog is an example of
Negative Punishment
What can cause an increase in fear, aggression and anxiety?
Using Positive Punishment
What is extinction?
The disappearance of a previously learned behavior after reinforcement stops.
In Operant Conditioning what does prompting refer to?
Visual signals or physical assistance to elicit a behavior rather than waiting for the dog to perform the behavior on his own.
Luring, physical manipulation, exaggerated hand signals that are not meant to be a cue in it’s final form, body blocking.
Fading the lure means
Removing a prompt or food lure as quickly as possible when training a behavior so the dog does not become dependent on the lure to perform the behavior.
Remove the food and only use the hand signal, then reduce or remove the hand signal and only use the verbal cue.
What is body blocking?
Using your body to block the dog’s movement.
What is Shaping?
Shaping is a method that is used to train more complex behaviors by breaking the behavior into small steps or approximations of the desired result then rewarding each step.
As you get closer to the desired behavior, you only reward successive approximations.
What is chaining?
Chaining is teaching multiple behaviors and then perform them in a particular order to result in the end goal behavior. Only the last cue in the chain is rewarded.
The first behavior becomes the cue for the next behavior.
Example: Fetch: Runs after the ball > picks up ball > carries ball back to you > drops the ball
What is Forward Chaining?
Typically just called chaining. The first behavior in the sequence is taught first, then the next, progressing to the full sequence.
What is Back Chaining?
Back Chaining is where you teach a complex behavior starting with the end step and then teaching each step that comes prior to the final step.
The theory is that the final behavior is practiced more frequently so it gets more heavily reinforced which can help build momentum for the preceding steps as they are introduced.
Example: Fetch - Drop Ball > bring ball > grab ball > run after ball
Do dogs generally respond to forwards chaining or backward chaining better?
Backwards Chaining
What is Stimulus Control
Dog performs behavior with discrimination and generalization.
Discrimination - dog sits when ask to sit, doesn’t lay down when asked to sit. Doesn’t sit if not asked. Knows the word.
Generalization - dog sits in living room, kitchen, outside, everywhere
What is the difference between Classical and Operant Conditioning?
Classical Conditioning elicits an involuntary, emotional or reflexive response. Association.
Operant Conditioning elicits a voluntary response reinforced with consequences. The dog has control over it’s actions. Learning.
Classical Counter Conditioning is often paired with
Desensitization
Operant Counter Conditioning is different from Classical Counter Conditioning because…
You are teaching the dog to offer a voluntary behavior (DRA/DRI)
Non-Associative Learning through gradual exposure is…
Desensitization
DS/CC
Desensitization & Counter Conditioning
Sensitization is
Amplified response to a stimulus
Habituation is
When an animal gets used to or ignores a stimulus.
It differs from desensitization as no rewards or punishers are offered. The dog simply gets used to the stimulus (usually an environmental stimulus) - example: pinecones falling on the roof or a new baby in the home crying.
