... for 20 daily sessions. The average rate in extinction decreased significantly as a function of the number of extinctions. A concurrent increase in rate occurred during VI reinforcement periods. Extinction occurred more rapidly as it was repeated. Assuming an exponential decay in rate of responding during extinction, the effects of repetition upon the parameters of ... linearly as a function of the number of extinctions, while the log initial rate decreased linearly. These changes in extinction parameters were in the same direction as previously ...
