PSGY2014: RW model and SOP model

According to the Rescorla-Wagner model, α represents the

• associability of the CS

• associability of the US

• magnitude of the US

• quantity of the US

The rescorla-wagner model predicts that a positive increase in associative strength will be achieved by a CS when

• λ = 1 and V = 0

• λ = 1 and V = 1

• λ = 0 and V = 1

• λ = 0 and V = 0

When there is a positive contingency between the CS and the US

• there is a net gain in inhibitory associations between CS and US

• the probability of US occurring after the CS is lower than the probability of the US occurring alone

• there is a net gain in excitatory associations between CS and US

• the CS does not form any association with the US

Which of the following effects of classical conditioning does the Roscorla-wagner model fail to account for?

• effects of CS-US contingencies

• Blocking

• downshift unblocking

• extinction

Which of the following statements about overshadowing is NOT correct?

• Overshadowing can occur with a single pairing of a CS-CS compound stimulus and an US

• the rescorla-wagner model cannot explain multi-trial overshadowing

• it refers to a reduction in associative strength to one CS due to the presence of another CS

Which of the following is an assumption of Wagner's SOP model?

• perceiving an external event makes its stimulus elements to rise from the inactive state directly to A2

• the capacity of the A1 state is limited

• elements in A2 state can move to A1 without passing through an inactive state

According to Wagner's SOP model, elements of CS in A1 will form __________ associations with elements of US in A2

• Excitatory

• Inhibitory

• no

Wagner's SOP model

• cannot explain one-trial overshadowing

• cannot explain spontaneous recovery of a conditioned response

• cannot explain extinction of associations between CS and US

Latent inhibition is a phenomenon

• where one CS in a compound stimulus forms inhibitory associations with the US

• pre-exposure to a CS increases its ability to form excitatory associations with an US

• that cannot be explained by the Rescorla-wagner model and Wagner's SOP model

• that can be explained by considering the experimental context as a stimulus

When an US precedes a CS in time

• the CS forms excitatory associations with the US

• the CS becomes a good predictor of the US

• backward conditioning occurs
