AP PSYCHOLOGY

Detailed explanation-1: -In operant conditioning, a fixed interval schedule is when reinforcement is given to a desired response after specific (predictable) amount of time has passed. Such a schedule results in a tendency for organisms to increase the frequency of responses closer to the anticipated time of reinforcement.

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: -Schedules based on elapsed time are referred to as interval schedules and can be either fixed-interval or variable-interval schedules. Ratio schedules involve reinforcement after a certain number of responses have been emitted.

Detailed explanation-4: -In operant conditioning, a fixed-ratio schedule is a schedule of reinforcement where a response is reinforced only after a specified number of responses. Essentially, the subject provides a set number of responses, then the trainer offers a reward.
