What typically occurs when the schedule of reinforcement is switched from continuous (under which Sniffy was fully trained) to a VR-5 as in Exercise 32?
a. Responding rapidly declines to almost zero, due to extinction.
b. The bar-sound association and action strength decrease, then increase.
c. The sound-food association and action strength decrease, then increase.
d. The bar-sound and sound-food associations both decrease, then increase.
b. The bar-sound association and action strength decrease, then increase.
Answer feedback: Because each bar press no longer produces the reinforcer, the bar-sound association will decrease, and responding will extinguish. This will produce a decrease in action strength as well. With additional exposure to the VR-5 schedule, responding will recover, and both the bar-sound association and action strength will return to their maxima.
