Chapter 3: Classical conditioning Flashcards
Blocking effect
interference with the conditioning of a novel stimulus because of the presence of a previously conditioned stimulus
comparator hypothesis
the idea that conditioned responding depends on a comparison between the associative strength of the conditioned stimulus (CS) and the associative strength of other cues present during training of the target CS
Conditioned compensatory response
a conditioned response opposite in form to the reaction elicited by the US and that therefore compensates for the reaction
conditioned diminution of the UR
a reduction in the magnitude of the response to an unconditional stimulus caused by presentation of a CS that had been conditioned with that US
CS preexposure effect
interference with conditioning produced by repeated exposures to the CS before the conditioning trails
aka. latent inhibition effect
dryg tolerance
reduction in the effectiveness of a drug as a result of repeated use
higher order conditioning
a procedure in which a previously conditioned stimulus (CS1) is used to condition a new stimulus (CS2)
relative waiting-time hypothesis
the idea that conditioned responding depends on how log the organism has to wait for the US in the presence of the CS, as compared to how long the organism has to wait for the US in the experimental situation irrespective of the CS
Stimulus-response learning
the learning of an association between a stimulus and a response
with the result that the stimulus comes to elicit the response directly
Stimulus-stimulus learning
the learning of an associatio between 2 stimuli , with the result that exposure to to one of the stimuli comes to activate a representation, or “mental image” of the other stimuli
sensory preconditioning
a procedure in which one biologically weak stimulus (CS2) is repeatedly paired with another biologically weak stimulus (CS1). Then, CS1 is conditioned with an with an US. In a later trial, CS2 also will elect the conditioned response, even though CS2 was never directly paired with the US
stimulus salience
the significance or noticeability of a stimulus
generally conditioning precedes more rapidly with more salient conditioned and unconditioned stimuli
Stimulus substitution
the theoretical idea that as a result of classical conditioning participants come to respond to the CS in much the same way they respond to the US
US preexposure effect
interference with conditioning produced by repeated exposures to the unconditioned stimulus before conditioning trials
US devaluation
reduction in the attractiveness of an unconditioned stimulus, usually achieved by aversion conditioning of satiation
learning is
acquiring new info
classical conditioning
learning about relationships between 2 events
learning to predict the future based on what has already happened
allows animals to predict or anticipate
activating or suppressing behvaiour
Ivan Pavlov
Father of classical conditioning
physiologist
digestive research without vivisection of dogs
disocovered “psychic secretions”
can use this to study associative learning and the nervous system
Vul’fson and Snarskii
Pavlov’s lab students
studied object learning
object learning
learning associations between different stimulus elements of an object
NS
neutral stimulus that precedes US
becomes the CS
Classical conditioning paradigm
NS + US presented together => UR
CS => CR
CR is usually the same as the UR
The CR is _______ upon the _____ being paired with the US/UR
conditional
CS
Habituation and sensitization are changes in the _______
UR because it is changes in a reflex that already occurs
Classical conditioning lead to
creating a conditional response by painting the CS and the US
creating a NEW response
Reproductive success Hollis et al. (1997)
investigated male aggressive behaviour in relation to mating success of Blue Gouramis
classically conditioned the males to anticipate the arrival of a female
these males had more reproductive success that did control males
first evidence of reproductive benefits from classical conditioning
Training:
- experimental group: 10 sec light -> 5min female (US)
- control: 10 sec light/4-6 hr/5 min female
test: after 18 days of training
- both groups: 10 sec light (CS) -> 5min female (US)
male and females interacted for 6 days
control males were more aggressive towards females
experimental group performed more nest-building beaver, spawned more, had more clasps, had more fry compared to control
Fears are _______. They are ____ responses
learned
complex
Watson and Rayner (1920) Fear conditioning
Lil’ Albert
