Six White Carneaux pigeons were exposed to fixed-ratio schedule components in a systematic replication of a study by Michael et al. (1981). Separation between median latencies for the two schedule components was demonstrated consistently, reproducing the general features of that research. In a subsequent manipulation, differential stimulus conditions were introduced into the intertrial intervals preceding onset of schedule components in an effort to enhance the likelihood that differential "waiting behaviors" would develop. Two subjects demonstrated a clear decrease in the magnitude of the latency splits following introduction of the cued ITI condition, while other subjects evidenced a similar but less distinct effect. Those results are discussed in terms of a stimulus change analysis of operant latency and are interpreted with reference to Skinner's (1950) conclusions regarding the role of waiting behaviors in latency measures.
