Effects of alternative responses on behavior exposed to noncontingent reinforcement.

Virues-Ortega et al. (2013) asked a simple question: does giving kids something else to do make NCR work better?

They used a single-case design with children who had intellectual disability. The team ran NCR two ways: free reinforcers only, and free reinforcers plus easy alternative tasks.

NCR alone cut problem behavior. Adding the extra tasks did not help much.

The schedule of free goodies, not the chance to do something else, drove the change.

Green et al. (1999) saw the same drop, but said kids simply chose to skip problem behavior when free snacks were there. Javier agrees the schedule matters, yet shows choice of tasks adds little.

Noel et al. (2016) later moved NCR into after-school clubs for students with autism. Preservice teachers got the same quick drop in disruption, proving the effect holds in noisy real-life rooms.

Ingvarsson et al. (2023) now argue NCR may work through quiet, antecedent cues rather than any operant back-and-forth. Javier’s bare-bones result fits that idea: the context of free reinforcement, not fancy responses, does the job.

You can keep NCR simple. Pick a strong reinforcer, deliver it on a fixed time, and watch problem behavior fall. Skip the extra tasks unless the team wants them for another goal. This saves staff time and keeps treatment easy to train.
