 That sounds good, so variable, variable, momentary, DRO, often, often, always, often, always, depending on who you are, what you are and where you learned and who you taught to, there could be a DR0. See my other videos and Brad's other videos to deal with this particular fucking issue because it drives me insane. Anyway, so a variable momentary DRO has to do with like a variable momentary time-sampling differential reinforcement of other behavior. In other words, if a problem behavior is occurring and you're trying to reduce it, you could use this procedure by taking a amount of time and saying, all right, on average, every three minutes, I'm going to look and see if this behavior is occurring, just for the briefest of moments. So when you look up, and it might be the next time you look up after three seconds and then it's nine minutes and then it's 10 seconds and then 80 seconds and then you get the idea. It's variable, which means we're going to work off of an average. It's momentary, so is the behavior happening at that moment? If the problem behavior is not happening, deliver the reinforcer. All right, so there's the DRO part. That's all there is to it. Thank you much. Cheerio.
