|
|
Term

|
Term
conditioned response (CR) |
|
Definition
responding to something that would not typically give you this response
normally you wouldn't salivate when you heard foot steps, but since you got food every time you heard footsteps now you salivate when you hear footsteps |
|
|
Term
|

Term
second-order conditioning |
|
Definition
a procedure in which an established conditioned stimuli is used to condition a second neutral stimulus
ex- 1) you show a metronome that triggers food and makes the dog salivate
2) you show a black board that stimulates the metronome and makes the dog salivate because before the metronome triggered food
3) you show just the black board and it will make the dog salivate
|
|
|
Term
|
Definition
responding to a new stimulus in a way simlar to the response produced by an established conditioned response
ex- a bell tone creates the response of salivation
if you hear another deeper bell tone it'll create salivation, even though the dog has never heard that "exact" sound |
|
|
Term
|
Definition
responding differently to a new stimulus than how one responds to an established conditioned response

|
Term
|
Definition
presenting a conditioned stimulus repeatedly, after conditioning, without the unconditional stimulus, resulting in a loss of responding
ex- a dog drools when he hears the bell, but if you repeatedly play the bell and don't give him food afterwards he'll stop drooling |
|
|
Term
|
Definition
learning that an event signals the absence of the unconditioned stimulus
