Just a brief reminder about behavior…teaching using positive reinforcement is not about bribing, and most certainly is not about force. Scientifically speaking, positive reinforcement is a consequence of a behavior that either maintains or strengthens it. As trainers, we are using positive reinforcement to build value for a behavior by pairing it with something the learner values. To be used effectively in teaching new behaviors, that reinforcement should be delivered contingently (meaning ONLY if the behavior occurs) and contiguously (meaning very closely following the behavior.) In this way, you are teaching your student this: WHEN I do THIS, THEN THIS positive outcome will happen.

An Assumption About A Reinforcer Can Be Wrong
When you are training your dog or any other animal, keep in mind, the value of a reinforcer can change.
