 That little critter back there extinct why because it's gone Make sense right same thing happens to behavior When you have a behavior that has been previously reinforced at a certain level in other words behaviors engaging in all sorts of things And you remove the reinforce for that behavior that the behavior tends to go away That would be extinction right so let me try that a little bit slower All right So the point is behaviors engaging it or you're engaging in behavior at a particular level whatever that is it could be up here Could be down there doesn't matter right so you're engaging in behavior, and then we remove the reinforcer for it The removal of reinforcers for that behavior will Ultimately not immediately ultimately Result in the decrease of that behavior right at least a pre-reinforced levels it might go away to zero like genuinely extinct There's other things that sometimes behavior comes back see another video for that But the point is is that extinction is the removal of reinforcement with the end goal the end effect of that behavior being reduced
