AP PSYCHOLOGY

Detailed explanation-1: -A fixed interval is a set amount of time between occurrences of something like a reward, result, or review. Some examples of a fixed interval schedule are a monthly review at work, a teacher giving a reward for good behavior each class, and a weekly paycheck.

Detailed explanation-2: -fixed-interval schedule ( FI schedule ) in conditioning, an arrangement, formerly known as periodic reinforcement, in which the first response that occurs after a set interval has elapsed is reinforced.

Detailed explanation-3: -Some of the advantages of an FI schedule are they produce an overall low but consistent rate of responding and they allow for reinforcement to be provided at greater intervals, (i.e., hourly, weekly, etc.) versus a more frequent basis.

Detailed explanation-4: -The variable interval schedule is unpredictable and produces a moderate, steady response rate (e.g., restaurant manager). The fixed interval schedule yields a scallop-shaped response pattern, reflecting a significant pause after reinforcement (e.g., surgery patient).
