dc.description.abstractPigeons' key pecks were maintained by variable-ratio or variable-interval schedules of food reinforcement. For pairs of pigeons in one group, variable-ratio reinforcement was arranged for one pigeon's pecks; for the second pigeon, reinforcement was arranged according to a variable-interval schedule yoked to the interreinforcement times produced by the first pigeon. For pairs of pigeons in another group, variable-interval reinforcement was arranged for one pigeon's pecks; for the second pigeon, reinforcement was arranged according to a variable-ratio schedule yoked to the interreinforcement responses produced by the first pigeon. For each pair, the yoking procedure was maintained for four or five consecutive sessions of 50 reinforcements each. In more than three-quarters of the pairs, variable-ratio response rates were higher than variable-interval rates within two sessions; in all cases, the rate difference developed within four sessions.
dc.description.sponsorshipEquipment was obtained with the aid of Matching Grant GE-2172 from the National Science Foundation Undergraduate Instructional Scientific Equipment Program to New York University; thanks are due R. E. Silvernman and M. R. D'Amato for initiating the grant proposal. Of the many contributors to the course within which the research was conducted, particular appreciation must be expressed to the late George G. Zimbardo, for the construction and maintenance of equipment, to Geraldine Hansen, for preparing uncounted instruction Sheets and data tables for distribution to students, to Barrington Graham and Frank Alicino, for care of the pigeons, to the several graduate students who served as teaching assistants, and to the undergraduate students of the University College of Arts and Science, New York University, whose reactions and suggestions influenced the development of the course. The procedure used for shaping the pigeons' key pecks was originally recommended by R. J. Herrnstein and W. H. Morse. Reprints may be obtained from A.
