Groups of subjects practiced operating the Multipoint Two-Hand Coordinator under various rest-work ratios. It was found that the groups which had equal ratios of rest-work, regardless of the absolute amount of time spent on either, performed at equal levels. Since many studies in the literature report different intervals of rest and work, making numerical comparisons between studies difficult, it is suggested on the basis of these results that equal rest-work ratios might be a useful comparison variable. Evidence was presented to support a hypothesis that groups practicing under massed conditions develop SIR (permanent work decrement), but distributed practice groups do not.
