Designs of experiments that demonstrated ABA renewal after extinction and punishment when each context’s association with reinforcement and nonreinforcement or punishment was controlled

Phase
Acquisition	Retroactive Interference Treatment	Test
Extinction
A: R1-food	A: R2–	A: R1, R2
B: R2-food	B: R1–	B: R1, R2
Punishment
A: R1-food	A: R2-food + shock	A: R1, R2
B: R2-food	B: R1-food + shock	B: R1, R2

A and B refer to contexts; – refers to extinction. Both experimental designs were within-subject designs; thus every subject received the treatments shown in each phase in an intermixed fashion. Bold indicates the response with the higher level during the test. [See Todd (18) and Bouton and Schepers (95).]
