Continuous reinforcement is a learning principle in which a behavior is rewarded every time it occurs. This method is often used in training animals or teaching new skills, as it helps to establish a strong connection between the behavior and the reward. For example, when a dog sits on command and receives a treat every time, it quickly learns to associate sitting with receiving a reward. This reinforcement schedule is effective for initial learning but may lead to rapid extinction of the behavior if the rewards stop. In contrast, other reinforcement schedules, like partial reinforcement, can help maintain the behavior over time by providing rewards intermittently.
