Variable Schedules of Reinforcement are also known as which?

• A. Also known as continuous reinforcement.
• B. Also known as partial or intermittent; No set pattern - random rewards keep dog gambling.
• C. Reward is given after every trial.
• D. Rewards are always predictable.

Answer: (B)

Variable schedules of reinforcement involve delivering rewards on an unpredictable basis, which is why they’re described as partial or intermittent reinforcement. Instead of a fixed pattern, reinforcement occurs after varying numbers of responses or after varying time intervals. This unpredictability keeps the dog guessing and tends to make the behavior more durable; the dog learns that a reward can come at any moment, so it continues performing the behavior even when rewards aren’t guaranteed every time. Examples include reinforcement after a changing number of responses (variable-ratio) or after changing time intervals (variable-interval).

The other descriptions don’t fit because they describe reinforcement that happens after every response or on a predictable pattern. That would be continuous reinforcement or a fixed, predictable schedule, not a variable one, which is the hallmark of partial or intermittent reinforcement.
