Graded A+ Get it 100% Correct
"V" (Rescorla-Wagner Model) - CORRECT ANSWER: strength of the association,
stronger association--> stronger ability to predict
Added criteria for S-S learning - CORRECT ANSWER: imposes a temporal relationship
between 2 stimuli alters the response to one, or both, stimuli
alpha (Rescorla-Wagner Model) - CORRECT ANSWER: The salience of the CS
(assumes between 0-1), higher salience--> faster conditioning
AMPA receptor - CORRECT ANSWER: Glutamate receptor that allows inflow of Na+
Attentional account assumes - CORRECT ANSWER: 1. That the organism has a limited
attentional capacity
2. That a CS must be attended for learning to occur
Autoshaping/sign tracking - CORRECT ANSWER: a pigeon comes to automatically
peck at a response key because the key light has been associated with the response-
independent delivery of food
backwards conditioning - CORRECT ANSWER: CS is presented after the US, makes
CS more likely to inhibit than stimulate
Beta (Rescorla-Wagner Model) - CORRECT ANSWER: A learning rate parameter for
the US
, Beta example - CORRECT ANSWER: Illness is a good US for the CS of taste, but light
is not, so association between illness and taste is learned faster than association
between illness and light
Between subjects design S-S - CORRECT ANSWER: 2 mutually exclusive groups, both
receive a tone and food, but one group receives a paired Cs+ while the other receives
an unpaired Cs-, finds conditioned response only in paired group
biological constraints (Garcia) - CORRECT ANSWER: It was originally assumed any
paired stimulus could cause learning no matter what the CS and US are, but found this
is not true because animals are biologically predisposed to learn specific cues
Blocking - CORRECT ANSWER: Animal acquires response to a CS in phase 1, in
phase 2 that CS is placed sequentially with a new CS, animal fails to learn CS2
because having learned CS1 predicts US --> blocks learning of other cues
conditioned eye blink - CORRECT ANSWER: usually done in rabbits, illustrated how a
neutral CS of a tone paired with the US of a puff of air into the eye --> animal blinking to
tone because it predicts puff
conditioned suppression - CORRECT ANSWER: amount of suppression of a consistent
behavior used as a measure of fear
conditioned taste aversion - CORRECT ANSWER: the animal is given a distinct taste,
then an injection to make them feel ill, after one pairing the animal avoids the food
because the body tells them it is inedible
delayed conditioning - CORRECT ANSWER: CS terminates when US begins, or CS
overlaps with US, creates a good CR (most effective)
