Which type of reinforcement strengthens a behavior by following it with a positive outcome?

Positive reinforcement is the process in which a desirable consequence follows a behavior, thereby increasing the likelihood that the behavior will be repeated in the future. In the context of horse training, this could involve offering a treat, affection, or verbal praise immediately after a horse performs a desired action, like obeying a command or executing a movement correctly. The key aspect of positive reinforcement is that it adds a pleasant stimulus after the behavior, enhancing the horse's motivation to engage in that behavior again.

This approach is effective because it encourages and motivates the horse, creating a stronger bond between the horse and handler while promoting positive learning experiences. The resulting behavior is more likely to be repeated because the horse associates the behavior with the positive outcome it received.
