An elementary student as a behavioral engineer.
A fifth-grader can run a desk-light token economy that quickly puts four first-graders’ study behavior under tight stimulus control.
01Research in Context
What this study did
A fifth-grade boy ran a token system for four first-graders. Each desk had a green light. When the light was on, the kids earned tokens for studying. The older boy flipped the lights and handed out tokens. The researchers turned the system on and off twice to be sure the lights really controlled study behavior.
What they found
Study time jumped whenever the lights were on. It dropped when the system stopped, and rose again when it came back. After the final phase, some good study habits stuck around even without tokens.
How this fits with other research
Bickel et al. (1984) later showed that even kindergarten peers can start and run a token economy without adult help, extending this peer-power idea to younger, special-ed students. Mann et al. (1971) kept the token economy but let the teacher run it with older kids, proving the method works even when you swap the manager. Petursdottir et al. (2019) now supersedes the original setup: they added a quick functional assessment and then slowly faded the tokens, getting the same big gains while teaching kids to work for natural rewards instead of coins.
Why it matters
You can hand the keys to a fifth-grader and still get clean experimental control. If you need fast stimulus control today, let a peer run a simple light-token system. If you want durable change, blend in Petursdottir’s fade-out plan next week. Either way, the desk light gives you an easy, visible cue that everyone in the room can see and trust.

03Original abstract
Four first-grade public school students exhibited non-study behaviors during a period when all children were to study individually. A fifth-grade student modified the maladaptive behaviors of the four first-grade students. Lights on the four students' desks, which were associated with opportunity for reinforcement, rapidly brought study behavior under stimulus control. Differential reinforcement of other behaviors dramatically decreased studying. Reinforcement was reinstituted and studying returned to a high and stable rate. Surreptitious post-experimental observation using closed-circuit TV indicated that the behavioral changes effected during the experimental phases were partially maintained by the regular classroom environment. A replication of the baseline phase with the observer in the classroom produced an increase in the rate of study behavior, indicating that the observer's presence acted as a discriminative stimulus for studying. An additional contingency requiring improved academic behavior was imposed before the fifth grader was given the opportunity to engage in the behavior modification experiment.
