Effects of Obtrusive Observation and Rules on Classroom Behavior of Adolescents in a Juvenile Residential Treatment Setting.

Two teachers in a locked residential school posted five classroom rules. No points, tokens, or praise followed the rules.

The researchers watched the adolescents over the study period. They counted problem behavior and appropriate responses every 10 minutes.

First they watched without rules. Then they added the posted rules. Last they removed the rules to see if behavior slid back.

Problem behavior dropped in both classrooms when rules were posted. One class also showed more hand-raising and on-task work.

When rules came down, problem behavior rose again. Just seeing the rules on the wall was enough to help most students.

Extra adult watching without rules changed nothing. The rules, not the observers, made the difference.

Cook et al. (2014) also cut off-task behavior in class, but they used white-noise headphones instead of rules. Both studies show simple antecedents can work without prizes or penalties.

Jessel et al. (2016) review papers where DRO schedules stop problem behavior by withholding reinforcement. Shawler et al. (2021) skipped reinforcement entirely and still got results. The new study suggests rules alone can function like a DRO-zero contingency for some kids.

Shawler et al. (2020) used response interruption to cut vocal stereotypy. Their tactic needed staff action every time. Posted rules in A et al. needed no staff response, saving effort while still helping.

If you run a classroom in a facility, try posting 3-5 clear rules before adding points or tokens. It costs nothing and may drop problem behavior fast. Track the data; if it works, you can skip heavier programs for some students.
