Strictly speaking, the title of this post doesn’t make any sense. Reinforcement strengthens behavior and positive reinforcement is adding something as a consequence to strengthen a behavior. So what the heck am I talking about?
One of the best ways to eliminate an unwanted behavior is to train another behavior to replace it. The technical term for this is Differential Reinforcement of an Incompatible behavior (DRI). It’s a very simple idea: find something that your dog cannot do at the same time as the unwanted thing, and then make doing that more rewarding.
Like many simple ideas, this is usually a lot easier to talk about than to actually implement in real life. What is the best behavior to use as a replacement? How frequently and for how long will you need to reinforce it? Are you simply replacing one annoyance for another? These are all questions that need to be considered. DRI is a thinking trainer’s tool – oftentimes it requires careful planning.
But there are plenty of examples of DRI working quite well in action. One of my favorites is using “Say Hi” for polite greetings.
Training a dog to approach a person and sniff their hand rather than jumping up on them is about as clear an example of DRI as you can find. Others use a sit or down stay as a solution for jumping up — which are good examples of DRI also — but I have found that “Say Hi” frequently works faster for a dog that is prone to over-arousal when she meets new people. It’s easier to get that type of dog to “do” something rather than to stay still.
Of course, DRI has a few pitfalls. One of them is hidden in plain sight, right in the name: Differential Reinforcement of an Incompatible behavior. Differential means reinforcing the alternate behavior and implies not reinforcing the unwanted one. In the “Say Hi” example, if people still reward jumping up with attention, chances are “Say Hi” (or sit or down stay) will fail.
DRI requires some reinforcement of its own. The new behavior needs to be well-trained and consistenly reinforced and the old, unwanted activity needs to be helped on its way out with either extinction or, if required some punishment.
