Abstract:
A way to test an animal response in extinction is by using the paradoxical reward effects. The one we used in the lab was the partial reinforcement extinction effects. This is the effects that determine the extinction effect, when an instrumental response was reinforced only some of the time. The pigeon was established and maintained on variable ratio (VR) schedule of food presentation. The schedule was then change to a fixed ratio (FR 1) scheduled for a predetermined number of reinforcers. After each component there was a period of ten minute extinction. The sequence was repeated a different number of times for us to determined relation between the amounts of reinforcer delivered during each components and the amount of responses during each extinction. There were fewer responses during extinction in the presence of stimulus recently correlated with the FR 1.
