Extinction Performance as a Function of Reinforcement Magnitude and Number of Training Trials
A number of studies have related performance during spacedtrial extinction to the number of trials and/or the magnitude of reward previously experienced during training. A comparison of these studies supports a suggestion made by Ison (1962) that performance during extinction is an inverted U-shaped function of the number of training trials, with the peak of the function determined by the magnitude of reward experienced during training.
