Ivan Pavlov
|
Studied digestive physiology in dogs
Digestive juices elicited by stimuli predicting food Associations between paired stimuli S-S Learning |
|
|
Pavlonian Conditioning
|
Unconditioned Stimulus (US)- automatcally elicits a response (reflex) Unconditioned response (UR)
food water sex pain etc. Conditioned Stimulus (CS) intiailly a neutral with respect to the US- does not intially trigger a response related to the motivational value of the US lights, sounds, tastes, ordors, etc. after pairings, elicits a conditioned response (CR) |
|
|
Vul'fson and Snarskii
|
Vul'fson- studied natural substances placed in the mouth. after multiple experiences, the mere sight of these substances elicited salivation
Snarskii- studied articial substances placed int he mouth black= CS Sour= US after experience seeing black liquid would elicit salivation -object learning |
|
|
Pavlonian Conditioning Paradigm
|
conditioned response
^ I Conditioned stimulus (CS) -> unconditioned stimulus (UR) -> unconditioned response -> UR |
|
|
Pavlonian Conditioning as Object learning
|
unconditioned stimuli are complex objects with multiple features. some of these elicit responding unconditionally whereas others do not.
initially ineffective features of the US object come to elicit responding unconditionally because of this, CS-US pairings are a natural feature of the environment outside the laboratory, the CS is not arbitrary with respect to the US but has an inherent relation to the US |
|
|
Fear Conditioning: Defensive behavior system
|
predator immienence continium
predator cannot appear -> predator might appear (reduced foraging) -> predator detected (freezing and CS) -> predator attacks (circa strike and US) |
|
|
Fear Conditioning
|
Training
Noise CS -> shock US measure freezing CR elicited by Noise CS CR (freezing to noise) acquired rapidly |
|
|
Conditioned Emotional Response
|
is an emotional response that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing experience.
|
|
|
supression ratio
|
ratio= cs responses/ cs responses +pre-CS responses
|
