CONDITIONING HISTORY AND HUMAN FIXED‐INTERVAL PERFORMANCE1

Abstract

The effects of two different conditioning histories upon human operant behavior under a FI 10-sec schedule of point reinforcements were investigated. Relatively high rates of continuous inter-reinforcement responding characterized the FI 10-sec performance of subjects with an FR 40 conditioning history. Low response rates with little or no inter-reinforcement responding were emitted by Ss with a DRL 20-sec conditioning history.
