NSCI exam 2 questions & answers
2024/2025
Pavlovian conditioning - ANSWERS-classical conditioning
-experience changes behavior
-important for understanding human behavior/thoughts/feelings
unconditioned reflex - ANSWERSinnate
conditioned reflex - ANSWERSlearned
trial - ANSWERSeach pairing of unconditioned and conditioned
Thompson et al - ANSWERS-A puff of air directed at a rabbit's eye causes the rabbit to blink, an
unconditioned response.
- A 1000 Hz tone is played independently and causes no eye blink response.
- A tone is played and shortly followed by an air puff and this sequence is repeated
. - The rabbit quickly learns to blink as soon as the tone is sounded, a conditioned response
higher order conditioning - ANSWERSPairing a neutral stimulus with a well-established CS. • The neutral
stimulus is NEVER paired with the US
trace - ANSWERSthe CS onsets and offsets before the US appears
delay - ANSWERSthe CS onsets before the US and is still present when the US appears
simultaneous - ANSWERSthe CS and US overlap
, backwards - ANSWERSthe US appears before the CS
contingency - ANSWERShow often the CS and US appear together
contiguity - ANSWERSinterval between trials
overshadowing - ANSWERSfor compound stimuli
more salient stimulus overshadows other
latent inhibition - ANSWERSFamiliar stimuli that were NOT previously paired with a US don't condition as
well as novel stimuli.
blocking - ANSWERSEstablished CS blocks learning for the new CS in a compound stimulus
How does latent inhibition related to the variable of Contingency? - ANSWERSlatent inhibition= lots of
prior exposure to CS without US. Stimuli not paired together which means low contingency
sensory pre conditioning - ANSWERSestablished by initially pairing two neutral stimuli—A and B—and
subsequently pairing A with an unconditioned stimulus. If B comes to elicit a response, then sensory
preconditioning has occurred. A
number of CS-US pairing - ANSWERS-first several pairings are most important
ITI - ANSWERStime between each paring of CR and UR
longer ITI=more conditioning
extinction - ANSWERSNEW learning-not forgetting
breaking the association between CS and US can extinguish CS->CR reflex
spontaneous recovery - ANSWERSTIME
