Which statement about the Rescorla-Wagner model's predictions is false? a) b) c) d) Extinction is the equivalent of unlearning, in that the associative strength of the extinguished CS returns to zero. Spontaneous recovery cannot occur; that is, whenever a subject stops responding during extinction, there should be no subsequent spontaneous recovery. Reacquisition of an extinguished excitatory association should occur at a faster rate and with fewer trials as compared to acquisition of the association during original conditioning. Acquisition of inhibitory strength will occur at the same rate and with the same number of trials for an extinguished excitatory CS and a different neutral CS.
