What term describes the addition of pleasant stimuli to increase the frequency of a desired behavior?

The term that describes the addition of pleasant stimuli to increase the frequency of a desired behavior is positive reinforcement. This concept in behavior modification involves providing a rewarding stimulus immediately following a desired behavior, which makes it more likely for that behavior to be repeated in the future. For instance, if a dog sits on command and immediately receives a treat, the treat is the pleasant stimulus that encourages the dog to sit again when asked.

Positive reinforcement is a crucial principle in training and behavior management, particularly in veterinary practice, where creating a positive experience can significantly reduce stress and anxiety for pets. It promotes a strong bond between the animal and caregiver, encouraging cooperative behaviors during veterinary visits.
