A procedure for thinning the schedule of time-out.

Three elementary students kept acting out in class. The team gave a short time-out every time the problem happened.

After behavior dropped, they thinned the rule. Instead of every time, time-outs came on a VR schedule. VR means the child never knows which act will earn the break.

They started with VR-2 (about every second response) and slowly moved to VR-8. Staff could warn first, but the time-out still followed if the behavior stayed.

Problem behavior fell fast under the thick VR-2 schedule. It stayed low as they stretched the ratio.

By VR-8, each child got only one short time-out every few days, yet the acting-out stayed down. No burst came back.

Staddon (1972) first showed brief isolation alone can cut misbehavior. Griffith et al. (2012) adds a schedule layer: you can thin that isolation and still keep the effect.

Coppage et al. (2017) looked at the opposite problem—long delays. They used a 10-second video replay right before a 15-minute time-out to keep its power. Both papers share one theme: keep the child linked to the consequence, either by thinning smartly or by bridging a delay.

Fisher et al. (2018) gives the theory behind the safety. They showed that denser reinforcement of the right behavior before thinning builds momentum. That momentum likely guarded against resurgence in the 2012 study.

You no longer need a time-out every single time. Start thick, then thin on a VR schedule while you teach the replacement skill. You save time, protect dignity, and still keep control. Try it next week: count the acts, set a VR-2 baseline, and stretch only after two flat days.
