Brief report: Signals enhance the suppressive effects of noncontingent reinforcement.

The team compared two ways to run noncontingent reinforcement.

One group got free reinforcers with a two-second tone first.

The other group got the same free items with no warning.

They watched how fast each setup cut problem behavior.

The signaled NCR stopped the behavior faster and deeper.

Responding dropped lower and stayed low sooner than with quiet NCR.

A tiny tone acted like a stop sign for the problem response.

Shimp et al. (1974) showed pigeons pick signaled food over quiet food.

That looks opposite, but both studies say the same thing: signals matter.

The 1974 paper used food the bird earned; the 2010 paper used free food to turn behavior off.

Same signal tool, different job.

Sanders et al. (1971) and Hearst et al. (1970) paired tones with shock and also saw quick response suppression.

They proved a brief cue can slam the brakes on behavior.

The 2010 study flips the shock into free candy yet still gets the slam.

It extends the brake-power of signals from scary events to nice ones.

If you run NCR to reduce problem behavior, add a short beep, flash, or word right before each delivery.

The signal tells the learner a free reinforcer is coming, so their motivation to problem-solve drops faster.

You may reach suppression in fewer sessions and use less total time.
