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.
