Verified step by step guidance

1. Understand the concept of reinforcement schedules: Reinforcement schedules are rules that determine how and when a behavior will be followed by a reinforcer. They are crucial in operant conditioning.
2. Identify the types of reinforcement schedules: There are four main types - fixed ratio, variable ratio, fixed interval, and variable interval. Each has distinct characteristics based on timing and frequency.
3. Define a variable interval schedule: In a variable interval schedule, reinforcement is given for the first response after a varying amount of time has passed. This schedule is unpredictable, which can lead to steady response rates.
4. Analyze the scenario: Pop quizzes are given at unpredictable times, which aligns with the concept of a variable interval schedule, as students cannot predict when the next quiz will occur.
5. Compare with other options: Fixed interval schedules have predictable timing, ratio schedules depend on the number of responses, and punishment by addition involves adding an unpleasant stimulus. These do not match the scenario of pop quizzes.
