Abstract: The present experiments demonstrate behavioral contrast with a fixed-interval (FI) and with a DRL' schedule of reinforcement: Each schedule maintains a higher rate of responding when it is alternated with a stimulus correlated with extinction than when it is alternated with a stimulus correlated with reinforcement.The occurrence of contrast with these two schedules casts doubt on accounts of contrast that de- pend on the effects of selective reinforcement or pun- ishment of different inter-response times. METHOD SubjectsFour experienced, adult, male, White Carneaux pigeons were maintained at 80% of their free-feeding body-weights.
