The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport
The Role Of Adventitious Reinforcement In Operant Discrimination, Alan Kamil, John W. Davenport
Avian Cognition Papers
Rats were trained in 2 SD-SΔ discrimination experiments in which the effects of an SD-postponement contingency during SΔ and temporal regularity of SΔ duration were assessed. Experiment I showed that discrimination is markedly facilitated by the presence of an SD-postponement contingency of either fixed or variable duration. Experiment II showed that variable-duration SΔ periods in a noncontingent schedule can also greatly enhance formation of an operant discrimination. These effects were attributed to differences in the probability of adventitious reinforcement of SΔ behavior by SD events.
