A variation of noncontingent reinforcement in the treatment of aberrant behavior.

Researchers tested a twist on noncontingent reinforcement. They added a five-second delay between the cue and the free reinforcer.

Kids with developmental delay and severe problem behavior joined. The team used an A-B-A-B design to compare plain NCR, NCR plus delay, and a DRO schedule.

Every child’s problem behavior dropped to almost zero when the delay was added. The new package also beat DRO on how often staff had to deliver treats.

Caregivers liked it because they could set a timer and hand out snacks on a fixed clock, no data sheets needed.

Matson et al. (1999) tried basic NCR for cigarette pica the year before. Their effects faded when they thinned the schedule. The 2000 delay fix seems to solve that fade-out.

Muharib et al. (2022) meta-analysis backs delay tactics too. They found DRA-based delays work best after FCT. The 2000 study shows a pure NCR delay can work even before you teach a new communication response.

Jeglum et al. (2022) later copied the near-zero result with adults who picked their skin. They used competing stimuli instead of a delay, proving NCR variants can hit the same low levels across very different behaviors.

If you run NCR now, add a five-second cue-to-reinforcer pause. You may see problem behavior fall further while you give more goodies and do less work. One timer, one rule, near-zero behavior.
