Abstract

The present study used a discrete-trials procedure to examine choice in pigeons presented with two- to five-component sequences of fixed-ratio schedules of reinforcement. Results of the first phase indicate that the majority of choice responses were allocated to the schedule containing the shorter initial fixed-ratio component regardless of the number of components assayed. These findings support the notion that temporally prior reinforcers minimize the effects of subsequent reinforcers and overall response requirements. Phase two findings indicate, however, that under some conditions, fixed-ratios other than the first, lawfully, although weakly, influence choice.
