There was an article in Journal of Applied Behavior Analysis in the mid-seventies that reported use of a mechanical clown attached to a crude noise meter. The title was something like, "Clowning around to stop clowning around." When noise levels fell below a certain level, buttons on the clown's coat would light up in sequence (from bottom to top) and, finally, the mouth would open and the eyes would light. It was most effective for very young grades.
It is a fairly good example of an AB (or interrupted time series) design, with validity established through replication across classrooms. jim clark wrote: > Anyway, I recall > reading and lecturing on a study many years ago now in which a > classroom (perhaps some kind of lab??) was wired so that when > noise levels were below a certain level music played.
