Abstract

Two pigeons were trained with positive reinforcement on a multiple FR VI 2 schedule. The VI 2 component was held constant while the FR component was changed from ratios of 1 to 300. After responding had stabilized at each FR value, VI responses produced briefly either the fixed‐ratio SD or a stimulus uncorrected with either schedule component. Compared to the effects of the uncorrected stimulus change, the fixed‐ratio SD produced a decrease in VI responding proportional to the size of the FR requirement. It is concluded that stimuli associated with high FR schedules served as punishment for the ongoing behavior. 1965 Society for the Experimental Analysis of Behavior
