 VR, VR, in our world means variable ratio. Anyway, you could do some real fun stuff with variable ratios on VR, using VR, virtual reality. They probably do because it's really heavy in the gaming industry. In fact, it's based on these schedules of reinforcement. This one is a very, very basic schedule of reinforcement, a variable ratio that has to do with the average number of responses before a reinforcer is delivered. Variable equals average, right? So on average, I'm gonna make you do 53 responses. There's the ratio piece, right? So before I deliver the reinforcer, really simple. In an operant chamber, in the lab, it's a pigeon pecking a key, a rat pressing a lever, whatever, brrrrrrr. So on average, they gotta press that damn thing 53 times before they get a reinforcer, but they never quite know when it's gonna come. Food, and they're never not gonna get food, food. And then they gotta wait a whole bunch more and they never quite know when it's gonna come. So they can develop these really freaky behaviors like this and they just keep going nonstop. And it's a high rate of responding and it's nice and consistent. And it's beautiful. It produces awesome responses. And now you understand a variable ratio of schedule of reinforcement. Find one in your life that doesn't involve a casino.
