Which quadrant of Operant Conditioning involves adding a stimulus to increase behavior?

Positive reinforcement is a critical concept in operant conditioning that involves adding a stimulus to strengthen or increase the likelihood of a desired behavior occurring again in the future. This typically means providing a reward or stimulus that the individual finds desirable immediately following the desired behavior. For example, if a dog is trained to sit and receives a treat each time it sits on command, this positive reinforcement enhances the probability that the dog will sit when asked in the future.

This approach is effective because it not only encourages the behavior but also creates a positive association with the action, making it more likely for the subject—be it an animal or human—to repeat the behavior to receive the reinforcement again. Therefore, positive reinforcement plays a crucial role in shaping behavior in both training scenarios and broader educational contexts.
