Dr. Alvarez is treating Marcus for a behavioral problem. First she records a baseline level of the behavior for several days. The rate of the behavior is quite high. Next she implements a behavior modification program based on punishment. When that approach has little success in reducing the behavior, she tries a second program based on reinforcement. The second treatment appears to work and the behavior is dramatically reduced. She then goes back to baseline and the behavior reverts back to pre-treatment levels. When Dr. Alvarez once again implements the second treatment method, the behavior goes away. This is an example of
A) an ABBAB design.
B) an ABCAC design.
C) an unsuccessful simple comparison design.
D) a multiple-baseline design.
