CHILD DEVELOPMENT PEDAGOGY

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 schedules are those where the first response is rewarded only after a specified amount of time has elapsed. This schedule causes high amounts of responding near the end of the interval but slower responding immediately after the delivery of the reinforcer.

Detailed explanation-3: -For example, a fixed-ratio schedule might involve the delivery of a reward for every fifth response. After the subject responds to the stimulus five times, a reward is delivered. So, imagine that you are training a lab rat to press a button in order to receive a food pellet.

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).
