well, the word no is a human construct, that is, as humans, it is something that we have created and put value in. The point is, to the bunny, “no” means nothing. Likely, the bunny is responding to the volume or the magnitude that you delivered the “No.” It either startled him/her or it was loud enough for the bunny to check out what it meant. But since it has no value to the bunny, it would not deter him or her from continuing the action.
In order for the “NO” to work, you would need to pair it with something so that the bunny would learn the meaning.
I know you said it was a joke, and i’m not taking it seriously, but just FYI, you could spank or hit your bunny. This would be considered a punishment procedure. The bunny could learn the meaning of this if you taught it. Also, for those of you who say “I would never use punishment” Just to let you know punishment in behavioral terms refers to something that is delivered after the behavior that will reduce the occurrence of the target behavior. What most people think as “punishment” is corporal punishment (e.g., hitting, spanking, whipping, etc.). That being said, when you use a water bottle to squirt the bunny in the face, that is punishment. When you clap your hands loud in an attempt to stop the behavior, that is punishment.
Anyway, I want to stress, that you can use punishment to teach, but i highly highly do not recommend it. Punishment is ineffective for several reasons:
1. Only effective when the threat of the punisher (you) is available. SO if you aren’t there, it won’t decrease behavior.
2. Punishment leads to undesired behaviors. You may cause the person or bunny (in this case) to not trust you, low self esteem, low self worth, also exhibit aggression and even counter control
3. Punishment doesn’t teach what to do, it only teaches what not to do.
Finally, something else to consider, punisment reinforces the person giving the punishment. So you become reinforced by the use.
Anyway, I know it was a joke, but I wanted to shed some light on it.
