The Effects of Fixed-Ratio Size in Multiple and Mixed Fixed-Ratio Schedules

Abstract

In compound fixed-ratio schedules, the factors controlling intercomponent pausing are not clear. One group of pigeons was trained on a multiple schedule in which ratio size of one of the two components was varied. Comparable manipulations were made for a second group trained on a mixed schedule. As the ratio was increased, the pause preceding that ratio also increased, while the pause before the other ratio decreased. Stimulus control was greater in the multiple schedule.
