Which reinforcement schedule states that a fixed amount of time passes before reinforcement?

• A. Memory skills
• B. Fixed ratio schedule
• C. Learning disabilities
• D. Fixed interval ratio

Answer: (D)

Time-based reinforcement is being tested. In a fixed interval schedule, reinforcement is delivered for the first response after a specific amount of time has passed. The key idea is that waiting time drives when reinforcement can occur, not the number of responses. As the end of the fixed interval approaches, responding typically increases, producing more activity closer to the time the reward becomes available. This contrasts with a fixed ratio schedule, where reinforcement depends on a set number of responses rather than time. The other options don’t describe a reinforcement schedule at all, so they aren’t appropriate. The choice given that reflects the time-based aspect—reinforcement after a fixed period—is the best match.
