Summary
A percentage timing schedule is one where reinforcement is set up during a given percentage of a fixed temporal cycle (15 sec. in the present case). Seven rats were run in a two-bar operant situation to determine the discrimination threshold of differential pay-off probabilities between the two bars. The threshold was found to be just less than the difference between reinforcement 23% and 37% of the time cycle. Other features of percentage timing schedules, particularly the behavioral effects of using different pay-off probabilities, were investigated and are discussed.
