Stimulus Control After Training with Fixed Interval and Variable Interval Schedules of Reinforcementdoi:10.1007/BF03394108Rats received discrimination training where light-on was the S+ condition and light-off the S- condition. 2 Ss were trained with a fixed interval (FI) 30-sec. schedule with a...
Rats obtained food pellets on a variable-interval schedule of reinforcement by nose poking a lighted key. After training to establish baseline performance (with the mean variable interval set at either 60, 120, or 240 s), the rats were given free access to food during the hour just before ...
Reinforcement refers to the giving of a reward after the behavior of interest has occurred. On a variable-interval reinforcement schedule, the reinforcement is given at irregular intervals. On the other hand, although fixed-interval schedules, where the behavior is rewarded every time, can lead to...
In two experiments, the performance of rats under constant-probability and arithmetic variable-interval schedules respectively was compared when the concentration of a liquid reinforcer was varied within sessions; in other sessions, half of the reinforcers were randomly omitted. When the discriminative fu...
Understand a variable interval and a variable-interval reinforcement schedule. Using a few variable-interval schedule examples, learn about their...
Schedules of reinforcement play a central role in theoperant conditioningprocess.The frequency with which a behavior is reinforced can help determine how quickly a response is learned as well as how strong the response might be. Each schedule of reinforcement has its own unique set of characteristic...
