REINFORCEMENT OMISSION ON TEMPORAL GO—NO‐GO SCHEDULES1

Abstract

Either a partial blackout, or the blackout plus a “feeder flash”, occurred in lieu of reinforcement on two procedures that produced opposite patterns of responding after reinforcement. Response rate was elevated after reinforcement omission on the procedure that produced a “pause-and-respond” pattern following reinforcement, but depressed after reinforcement omission on the procedure that produced a “respond-and-pause” pattern. The effect of blackout plus feeder flash was generally intermediate between the effects of blackout and the effects of reinforcement. These results are consistent with an interpretation of reinforcement omission effects in terms of the discriminative temporal control exerted by reinforcement and stimuli similar to it.
