The difference between an interval schedule of reinforcement and a ratio schedule of reinforcement is the following:
Interval schedules of reinforcement are those where the response is rewarded only after an amount of time has elapsed. If the amount of time elapsed is a <em>specified amount of time</em>, the interval schedule is fixed, if it is an<em>unpredictable amount of time</em>, the interval schedule is variable.
Ratio schedules of reinforcement, on the other hand, are those where a response is reinforced only after a number of responses. If the number of responses is a <em>specified number</em>, the ratio schedule is fixed; if it is an <em>unpredictable amount of responses</em>, the ratio schedule is variable.
