Table 1.

Designs of experiments that demonstrated ABA renewal after extinction (Todd, 2013) and punishment (Bouton & Schepers, 2015) 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

Note. 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.
