Behaviorism
Focus on stimulus and response
Classical vs. Instrumental Conditioning
Classical Conditioning (Pavlovian)
Association of a neutral stimulus with one that consistently elicits a response
Associating between 2 stimluus
Model
Unconditioned stimulus (UCS) leads to unconditioned response (UCR)
Unconditioned = unlearned (already there)
Then pair a conditioned stimulus (CS) with the unconditioned stimulus (UCS)
So the conditioned stimulus (CS) leads to a conditioned response (UR)
For Pavlovs Dog
Meat powder (UCS)
Salivation (UCR)
Ring bell (CS) every time you give UCS
Ring bell and he will salivate (UR)

Pay attention to the CS
We are hard wired to lean because we have an orienting reflex (humans will
learn no matter what)
Model is not response contingent
Doesn’t matter what dog does, as long as both stimuli are present
CR isn’t the same as the UCR
UCR is out of awareness
CR is a cognitive/ CNS thing
Many possible UCS, UR, CS, CR for each situation
Classical Conditioning of Love
Don Byrne
Reinforcement- Affect Model
Arousing stimulus (music) leads to positive feelings
Stimulus is associated with the neutral stimulus (stranger)
May and Hamilton
Females listen to different music and rate males
Helps Byrne’s Help reinforcement affect
Showed that it works better when negative
Acquisition Curves
Show response strength
Eg. A Latency Response: how long it takes for CR to occur from CS),
comparing many trials

Curve that should go down (negatively accelerated)
Quicker response when more exposed to it
Eg. Output Measure: quantity response
How much a dog salivated every time it hears a bell
Forward Pairing: condition stimulus before unconditioned stimulus
Bell then meat
Best way to learn
Simultaneous Pairing: same time CS and UCS
Backward Pairing: present CS after UCS
Meat then bell
Higher Order Conditioning
Pair primary CS with another neutral stimulus (secondary CS)
Transferring the CS from bell to a light for example
Doesn’t work very well, because it loosens the CS-UCS bond
Loss of CR
Extinction
CS no longer pairs with UCS
Decrease in reponse strength
