Operant Conditioning Flashcards

What is Operant Conditioning?
A type of learning process where behaviors are modified by associating them with consequences
The learning of behaviors strengthening or weakening based on consequences (Law of Effect)
Antecedent (or stimulus)
Behavior (or response)
Consequences
Skinner Box
an apparatus for studying operant conditioning in animals (typically rats or pigeons) in which the animal is isolated and provided with a lever or switch which it learns to use to obtain a reward, such as a food pellet, or to avoid a punishment, such as an electric shock.
What are the four quadrants of learning
+P, -P, +R, -R
What does +P mean?
Positive Punishment- something added intended to discourage a behavior
i.e. spraying a cat with water for scratching the couch
What does -P mean?
Taking away something the dog wants or enjoys as a consequence for performing an undesirable behavior
i.e. if your dog jumps up on you, you could turn your back and walk away, removing your attention as a negative punishment for the jumping behavior.
What does +R mean?
Positive Reinforcement- Rewarding good behavior to encourage it’s continuation
i.e. treat a dog that sits
What does -R mean?
Negative Reinforcement- a technique that encourages a desired behavior by removing something unpleasant.
i.e. Releasing pressure on the leash when the dog stops pulling
Spunky chews on a bone and when another dog approaches he growls and the dog goes away.
Pushing a dogs butt until he sits and when he does sit the pressure of your hand is removed.
“Makes the bad thing go away”
What is Operant Counter Conditioning?
Is a training technique that teaches a new behavior to replace an unwanted one. It involves changing a person or animal’s emotional response to a stimulus.
How it works-
Identify the unwanted behavior: For example, a dog that barks and lunges at other dogs
Train an incompatible behavior: For example, teach the dog to watch you instead of barking
Associate the new behavior with a positive outcome: For example, reward the dog with praise when it watches you instead of barking
Voluntary Response
A behavior that is learned through OC
Skinners operant conditioning allows external stimulus to be associated with a voluntary response
When you teach your dog to sit the verbal cue “sit” has a positive consequence, such as a treat. Sitting is a VOLUNTARY response
Differential Reinforcement of Excellent Behavior (DRE)
Nit Pick
You reward the dog only when they are giving you a certain behavior following whatever specific criteria you’ve established
i.e. reward a dog for a sit only if he is sitting solidly on the floor chest facing front and with the dog giving you full eye contact
Differential Reinforcement of Other Behavior (DRO)
Gives a little more leeway because you are asking and rewarding for ANY other behavior except the one the dog is doing
i.e. would be to set a timer and reward a dog with a treat if they remain calm and sitting on their bed for the entire duration of the timer, essentially reinforcing the absence of unwanted behaviors like barking or pacing during that time, instead of just punishing the unwanted behaviors when they occur; this way, the dog learns to actively choose to stay calm for a set period to receive a reward.
Differential Reinforcement of Incompatible Behavior (DRI)
Similar to DRA …Alternative behavior but you want to specifically reinforce a behavior that is not compatible with the inappropriate behavior.
i.e. Reward sit not jump, mouthy dog carries a toy
Differential Reinforcement of Alternate Behavior (DRA)
Dogs cant do two behaviors at once. Instead of lunging @ guest ask what do you want to do=go lay on bed
Using +R we ask the dog to do some alternate behavior
i.e. touch hand vs bark at dogs, Go to crate vs jump on someone
OC Reinforcement Schedules
Continuous reinforcement schedule
Intermittent reinforcement schedule
FI, VI, FR, VR
Variable Ratio (VR)
Rewarding after an unknown or unpredictable number of responses
i.e. The dog must sit twice, then five times, then three times, etc. before getting a treat
High and steady response rate and the most resistant of extinction
In intermittent reinforcement schedule what does RATIO and INTERVAL stand for?
“RATIO” refers to the number of responses required before reinforcement is given
“INTERVAL” refers to the amount of time that must pass before reinforcement is given
Essentially, ratio is based on behavior count, and interval is based on time elapsed.
Fixed Interval (FI)
A behavior will be reinforced only after a set, predetermined amount of TIME has passed since the last reinforcement, regardless of how many times the behavior is performed during that interval; essentially, the reward is given after a fixed time period has elapsed, not based on the number of responses made
I.e. rewarding a dog every 5 min that they stay calmly on the bed, regardless of how many times they got up; essentially the dog is reinforced for staying calm for a consistent time interval.
Most susceptible of extinction
Fixed Ratio (FR)
Rewarding after a set or predictable number of responses.
i.e. Dog sits three times before getting rewarded
Variable Interval (VI)
Dog is rewarded after an unpredictable time has elapsed.
i.e. The dog may be rewarded for holding a sit for 5 secs or 8 secs or 3 secs
Continuous Reinforcement Schedules (CRF)
Every time a dog gives a correct response the dog is rewarded
Usually in the beginning of learning
What does Punishment do?
Decreases a behavior
What does reinforcement do?
Increases the behavior
What are the five consequences of behavior?
Neutral- no consequence
+P, -P, +R, -R
What is the difference between -R and -P?
In dog training, negative reinforcement increases a desired behavior by removing something unpleasant, while negative punishment decreases an undesired behavior by removing something the dog likes
