The S-R, S-S and the S-R, S-R models in Exercise 15 predict that, following first-order excitatory conditioning of the CS (pairing it with the US) in Stage 1, habituation of the UR in Stage 2 produces what effect when the CS is subsequently presented by itself in Stage 3?
a. The UR will quickly reappear.
b. The CR will be essentially unchanged.
c. The CR will no longer resemble the UR.
d. The now-habituated UR will interfere with the CR.
