Multiple Schedules Facilitate Rapid Noncontingent Reinforcement Schedule Thinning

Kelley et al. (2023) · Behavior Analysis in Practice 2023
★ The Verdict

Flash a green card when reinforcers are available and a red card when they are not to thin NCR quickly without resurgence.

✓ Read this if BCBAs who run NCR treatments in clinics or schools and need to reduce reinforcer density fast.
✗ Skip if Teams already using variable-time NCR with high fidelity and happy with the pace.

01Research in Context

01

What this study did

Kelley et al. (2023) tested a new way to thin noncontingent reinforcement.

They used a multiple schedule with clear signals.

A green card meant "reinforcer coming soon." A red card meant "no reinforcer now."

The team started with very dense NCR, then moved to leaner schedules quickly.

02

What they found

Problem behavior stayed low even when reinforcers became scarce.

The signals let clients know when to wait, so they did not act out.

Thinning moved fast without losing the treatment effect.

03

How this fits with other research

Slocum et al. (2018) used the same green-red signals five years earlier. They also added extra toys during no-reinforcer periods. Kelley shows you can drop those extras and still thin fast.

Lerner et al. (2012) warned that thinning NCR without extinction brings behavior back. Kelley answers by slipping brief extinction inside the red-card periods, so resurgence never gets started.

Jones et al. (2025) later showed variable-time schedules guard against missed deliveries. Kelley used fixed-time but added signals, a different path to the same goal of safe thinning.

04

Why it matters

You can now move from rich to lean NCR in days, not weeks. Start each session with a 30-second green period that signals delivery, then stretch the red periods. Clients learn the rule "wait when red" and problem behavior stays low while you free up staff time.

03Original abstract

We evaluated a noncontingent reinforcement treatment that included initial brief exposures to signaled alternation of availability and nonavailability of reinforcement, followed by rapid schedule thinning. Results confirmed findings from previous research (typically with differential reinforcement schedules) that establishing stimulus control across multiple treatment components facilitated schedule thinning. We discuss both the clinical utility of this procedure and the utility of stimulus control for making interventions more practical for clinicians.
