Continuous reinforcement, in operant conditioning, is a reinforcement schedule in which every correct response is followed by a reinforcer. The concept was developed within the experimental analysis of behavior and popularized by B. F. Skinner through studies with animals and humans. In practice, a dog is reinforced after every sit, or a student receives praise after each correct answer. The reinforcer can be primary (food, warmth) or secondary (praise, tokens) but must be delivered consistently after each correct response.

The primary effect of continuous reinforcement is rapid acquisition of the target behavior, as the reinforcement contingency is unambiguous. However, it is also highly susceptible to extinction; if reinforcement stops, the behavior declines quickly because the subject learns the contingency is no longer reliable. In natural settings it can be difficult to maintain, and over-justification or satiation can reduce motivation.

Continuous reinforcement is contrasted with partial or intermittent reinforcement schedules, such as fixed ratio, variable ratio, fixed interval, and variable interval. Partial reinforcement often yields greater resistance to extinction and can be more durable in real-world learning. In educational and therapeutic contexts, continuous reinforcement is useful during initial teaching or skill acquisition, after which other reinforcement schedules may support maintenance and generalization.
