The effects of ratio length and shock intensity on bar pressing were examined in three rats in two escape‐from‐shock experiments. In Experiment I, shock intensity was held constant while the schedule was varied from FR 1 to FR 20. The latency of the first escape response increased with FR length while the escape rate, computed as over‐all rate in shock minus latency of the first response, decreased at FR 20. In Experiment II, the schedule was held constant at FR 5 while shock intensity was manipulated. Latency decreased as intensity increased, while escape rate increased with intensity, passing through a maximum for two subjects. Responses occurring during the last 100 sec of the 2‐min escape period decreased as the FR increased for all subjects, and decreased as shock intensity increased for two subjects.
