RESISTANCE TO EXTINCTION IN THE GOLDFISH FOLLOWING SCHEDULES OF CONTINUOUS AND VARIABLE INTERVAL REINFORCEMENT.
Four goldfish (Carassius auratus, comet) were reinforced with food when they intercepted a beam of light. Each fish performed on both CRF and VI 50-sec schedules. In subsequent extinctions, the CRF schedule produced more responses on the first day than did VI, but after the first day the post-CRF rate dropped much more rapidly. These results agree with those previously obtained in birds and mammals.
