The components of concurrent schedules of reinforcement were separated temporally by placing interval schedules on the changeover key. Both main and changeover key performances were examined as a function of the relative reinforcement rates and of the changeover schedule duration. Main key performances changed quantitatively, but not qualitatively, as the temporal separation of components increased, with performance becoming less sensitive to relative reinforcement rates with increasing temporal separation. In general, absolute response rates were adequately predicated by the relative reinforcement rates, but in some conditions the absolute response rate was also affected by the availability of the responses. The rates of responding to change between components were controlled by the reinforcement rates in the both of the concurrent schedule components, and, in some conditions, varied independently of main key response rates. The rates of responding to alternate between components were a direct function of the reinforcement rate in the absent component, and were an inverse function of the reinforcement rate for main key responding in the same component. Animals alternated between the concurrent schedule components even when alternation reduced the overall rate of obtained reinforcement.
