BERNAL-GAMBOA, Rodolfo  and  NIETO, Javier. Evidence of ABC instrumental renewal formerly eliminated by extinction and omission procedures. Rev Arg Cs Comp. [online]. 2018, vol.10, n.2, pp.11-18. ISSN 1852-4206.

One experiment used a free operant procedure with rats to evaluate renewal of a response previously eliminated by using omission training or by using an extinction treatment. All rats were trained to press a lever for food in context A. Then, the operant responses were eliminated in a second context. In this phase, half of the subjects received an omission training (i. e., delivery of food for withholding responding), while the other half received an extinction procedure. Finally, a within-subject ABC renewal test was conducted. The results demonstrated that all rats showed higher levels of responding when they were tested outside extinction context, regardless the procedure used during the elimination phase.
