Understanding stimulus control generated in instrumental learning requires the direct investigation of discriminated response and reinforcer (incentive) processes acquired exclusively through the response‐reinforcer contingencies operating on complex (multicomponent) baselines. Two series of stimulus‐compounding studies accomplished this direct investigation. In one series, the independent variable was the relative reinforcement between schedule components; in the second series, it was relative response rate between components. Stimulus‐compounding tests revealed that response and incentive processes enhanced each other when in agreement, counteracted each other when in opposition, and produced intermediate results when only one factor was operating. This pattern of results led to the conclusion that these factors were algebraically combining and to the development of a response/incentive matrix reflecting these dynamics. This two‐factor analysis was extended to the peak‐shift effect in stimulus generalization experiments and to the generation of inhibitory control. Two decades of stimulus compounding and peak‐shift research were organized within this two‐factor framework, extending this traditional approach to learning to active research areas heretofore not systematically considered in these terms.
