 Is your mic on? I'm not sure. That was recorded and that was awesome. Soyeon Kim, you've asked us a great question about evocative effects and establishing operations and abolishing operations and evative effects. I suppose we should give you an answer. So they're all directly related to each other and sometimes the terminology gets a little, oh I don't know, confusing. So let's give you a little bit of a definition and an example and we'll kind of connect all these pieces for you because they are directly related to each other. So if we have an establishing operation, so we're going to establish the effectiveness of a reinforcer, if you will, then that establishing operation has an evocative effect on behavior. In other words, it's going to bring behavior about. So for example, if I deprive you of water, so I make you go outside and you run five miles or ten kilometers, whatever it is. So you go out there, you run a 10k and I say you can't have water. So now I have established the effectiveness of water as a reinforcer. In other words, it's going to evoke a response of water seeking behavior. So you're going to go out and you're going to find water so we evoke that behavior. So we brought it about through an establishing operation of depriving you. So then you're going to drink the water and guess what that is? That is going to have an abate of effect, right? Why? Because it is a abolishing operation, right? So you're thirsty, now you drink the water, it decreases the value of water, it abolishes the effectiveness of water as you're drinking it, which then is going to reduce the likelihood that you go out and seek the water or you reduces your drinking it at that particular moment. In other words, an abate of effect. So establishing operations, evocative effects. I keep having time for this word today. Abolishing operations have an abate of effect. So they do get a little confusing, but I hope that clears it up for you. Thank you very much and ask more questions!
