Classical/ Respondent Condioning
Based on internal responses to naturally occurring smuli
Ex: the taste of a lemon will automacally make us like “oooo”
Infant natural response example
UCS = Uncondioned Smuli
Ex: for infants, sugar (the UCR) and infants will smile and lick their lips (UCS)
Ex: Adult natural paring, the lemon (UCS), adults will pucker their lips (UCS)
Ex: Animal natural response, food (UCS), dogs will salivate and drool (UCR)
Studied salivary responses in dogs
Is a natural response – no learning involved
Noted dogs salivated at sounds (e.g. footsteps; tone)
How did the “associaon” with the tone come about?
-The dogs had already ancipated that they were ge3ng food before they were even being
given the food, the dogs became used to Pavlovs experiment
-He then tried to use a cking sound to relate the feeding of the dog to that sound, and the
cking sound alone made the dogs salivate, even without the food (This was a condioned
*UCR (Uncondioned Response) & CR (Condioned Response) are the same thing, what
elicits them is dierent!
*Insert Classical Condion Terms
**MUST KNOW THE CONCEPTS BEHIND EACH TERM, given a scenario, so know them!
-the mer/clicker (metronome) is the neutral smulus
Classical condioning in adversing:
Many adversers a<empt to make their products condioned smuli that elicit pleasant
emoonal responses by pairing their products with a<racve or popular people or
sexual imagery
