A comparison of two lag schedules of reinforcement on response variability in pigeons

The delivery of reinforcement has been used to increase the variability of responses. The current study sought to compare two Lag schedules of Reinforcement Lag-3 and Lag-8 to determine if the higher value of a Lag schedule can produce greater response variability. Subjects were four white Carneau Pigeons from the pigeon lab at California State University, Stanislaus. Using an alternating treatment design, results concluded that a higher value of a Lag schedule, Lag-8 produced greater variability for two of the pigeons but not for all pigeons in the study. The possible reasons for this finding, limitations, and future research recommendations are discussed below.
