 Schedule thinning folks often referred to as graduate school go to one and you'll find out No, really no schedule thinning is about reducing the amount of reinforcement available kind of so Change you change the contingency right so you change the schedule of reinforcement as time goes on So so kind of like a progressive schedule progressive schedule involved thinning the schedule of reinforcement, right? So if we start on a FR schedule we can start an FR 10 we can move into an FR 15 and FR 20 if our 25 if our 50 You get the idea so the organism has to work more to earn a reinforcer The variable interval any of that stuff any of the interval based up to you just make the interval longer That's called thinning the schedule of reinforcement. You're delivering fewer reinforcers, but asking for more behavior in return It's tricky to do and if you push it too far you end up with some some interesting side effects Including one of those would be ratio strain There's an extinction effects and frustration and anger and violence and all sorts of crazy things again Like I said schedule thinning is really just about graduate school
