Quizplus · Accepted Answer

Both variable ratio and variable interval schedules have been found to be the most effective in maintaining behavior over time. Variable ratio schedules reinforce behavior after an unpredictable number of responses, which leads to a high and steady rate of responding. Variable interval schedules reinforce behavior after an unpredictable amount of time has passed, which leads to a consistent but moderate rate of responding. These schedules are also less likely to result in extinction, as the unpredictable nature of the reinforcement makes it more difficult for the individual to determine when the reinforcement will occur.
