When Skinner withheld the reinforcers for rats in a Skinner box continuously, the rats:
a. looked for food elsewhere in the box.
c. eventually stopped pressing the lever.
b. ran wildly around the box.
d. did nothing.
ANS: C
FEEDBACK: The rat's bar-pressing actions can be controlled by presenting or withholding the reinforcers or by presenting them at a different rate. Withholding the food extinguishes operant behavior. If the unreinforced behavior no longer works, in that it no longer brings a reward, after a while it will stop.
