CONTINGENT AND NONCONTINGENT RESPONSE RATES AS A FUNCTION OF DELAY OF REINFORCEMENT

Rats were exposed to a VI 1-min reinforcement schedule in which reinforcement was delayed for varying intervals, and responses during the delay periods had no programmed effects. Response rates during the schedule declined as the delay length increased, but rates during the delay periods were not a simple function of delay length. © 1969, Psychonomic Journals, Inc..
