Is “choice” a code word for negative reinforcement?
It can be. Seems like that’s the context where I see it pop up the most.
I’ve written a lot about choice. Two of my major points are:
- Many people are confused about using choice as an antecedent vs. a consequence; and
- People are rarely referring to choices between positive reinforcers when they write about their animals having a choice.
But here’s another thing that gets under my skin. These days it seems like many people who use the language of choice to describe their training are referring to the fact that they permit the animal to leave as relief from a difficult task. For instance, in a husbandry session, the dog may receive a food reinforcer for cooperative behavior. That constitutes positive reinforcement if we see cooperative behavior (usually staying still or focusing on something) increase or maintain. 1) The dog is allowed to leave as often as she wants. The session starts back up if she returns. The leaving constitutes negative reinforcement if we see leaving increase or maintain. But remember: escape is only a reinforcer if the activity is unpleasant.
Letting the dog leave is a good thing. But there is a big drawback if it is planned on as an expected response and built into a protocol.
Building escape behavior into a protocol can provide a disincentive to the human to make the process as pleasant for the dog as possible. Rather than working harder to create a situation where the dog doesn’t want to leave, the trainer can focus on saying that the dog is “empowered” by the ability to leave. On the contrary, some trainers, including myself, consider a dog repeatedly leaving as evidence that we have not worked hard enough at making the experience pleasant. It’s a failure, not a goal. It means we didn’t set up our antecedents and graduated exposures well enough.
Forced vs. Free Choice
I have written about forced and free choice before. Forced choice applies to our husbandry example. The dog can stick with the session and get food or another appetitive stimulus, or the dog can leave. Leaving usually leads to an environment that is bare of other positive reinforcers, or has very weak ones. We deliberately set things up that way as an incentive for the dog to stick with the session. There is no shame in that. Controlling other reinforcers is a part of positive reinforcement-based training … Read more >
