Matell, Matthew S.; Della Valle, Rebecca B. – Learning & Memory, 2018
Presentation of a previously trained Pavlovian conditioned stimulus while an organism is engaged in operant responding can moderate the rate of responding, a phenomenon known as Pavlovian-to-instrumental transfer. Although it is well known that Pavlovian contingencies will generate conditioned behavior that is temporally organized with respect to…

Nieto, Javier; Uengoer, Metin; Bernal-Gamboa, Rodolfo – Learning & Memory, 2017
One experiment with rats explored whether an extinction-cue prevents the recovery of extinguished lever-pressing responses. Initially, rats were trained to perform one instrumental response (R1) for food in Context A, and a different instrumental response (R2) in Context B. Then, responses were extinguished each in the alternate context (R1 in…

Davies, Don A.; Hurtubise, Jessica L.; Greba, Quentin; Howland, John G. – Learning & Memory, 2017
The trial-unique, delayed nonmatching-to-location (TUNL) task is a recently developed behavioral task that measures spatial working memory and a form of pattern separation in touchscreen-equipped operant conditioning chambers. Limited information exists regarding the neurotransmitters and neural substrates involved in the task. The present…
