Detailed explanation-1: -Among the reinforcement schedules, variable ratio is the most productive and the most resistant to extinction. Fixed interval is the least productive and the easiest to extinguish (Figure 1). Figure 1. The four reinforcement schedules yield different response patterns.

Detailed explanation-2: -A Fixed Interval Schedule provides a reward at consistent times. Forexample a child may be rewarded once a week if their room is cleaned up. Aproblem with this type of reinforcement schedule is that individuals tend to wait until the time when reinforcement will occur and thenbegin their responses (Nye, 1992).

Detailed explanation-3: -In the fixed-ratio schedule, resistance to extinction increases as the ratio increases. In the fixed-interval schedule, resistance to extinction increases as the interval lengthens in time.

Detailed explanation-4: -Variable ratio schedules maintain high and steady rates of the desired behavior, and the behavior is very resistant to extinction. Interval schedules involve reinforcement of a desired behavior after an interval of time has passed. In a fixed interval schedule, the interval of time is always the same.

Detailed explanation-5: -fixed-ratio schedule ( FR schedule ) “FR 1” means that reinforcement is given after each response; “FR 50” means that reinforcement is given after every 50 responses; and so on.
