What is a fixed interval reward schedule?

• A. Reinforcement after a random time interval.
• B. Reinforcement after a fixed number of responses.
• C. Reinforcement after the MWD responds to a command for a specific period of time.
• D. Reinforcement after every correct response.

Answer: (C)

Fixed interval reinforcement is about delivering a reward after a set amount of time has passed, provided the target behavior occurs or is maintained. When training a MWD, this often means the dog must perform or sustain a command for a specified duration, and once that fixed period elapses, reinforcement is given. This creates a predictable window where the next reward becomes available after that fixed time, encouraging the dog to respond as the interval ends. The other descriptions point to different schedules: a random time interval corresponds to a variable interval schedule, reinforcing after an unpredictable amount of time; a fixed number of responses describes a fixed ratio schedule; and reinforcement after every correct response is continuous reinforcement. The chosen option aligns with the timing aspect of a fixed interval by tying reinforcement to a defined period of sustained behavior.
