Dr. Skinner wants a pigeon to learn to peck a button in its cage. He first records how often the pigeon pecks the button. Then, after 3 days, he begins to give food to the pigeon every time it pecks the button. The pigeon's rate of pecking the button increases. After 3 days, he quits giving the pigeon food contingent on its pecking the button. The pigeon's rate of pecking the button decreases. After 3 more days, Dr. Skinner begins giving the pigeon food for pecking the button again, and its rate of pecking increases again. What kind of experimental design has Dr. Skinner used?

Question 2

Jamal was continually late to work. In an effort to reduce this behavior, his supervisor told him that for each minute he was late to work, it would be deducted from his break time. During the week, the supervisor noticed that Jamal was no longer coming late to work. In an attempt to see if it was indeed his intervention that was the cause of Jamal's behavior change, the supervisor told him that the following Monday, there would no longer be a penalty for coming late to work. Jamal's behavior of lateness returned. Convinced, the supervisor reinstated the consequence. Jamal again began arriving to work on time. What design does this procedure describe?
 
  a. Teaching Design
  b. Changing Conditions Design
  c. ABAB
  d. AB
