Abstract

Conditioned 4 male Bettas to emit an operant response reinforced by the opportunity to view a film image of another male Betta. In Exp. I, performance under continuous reinforcement (CRF), fixed ratio 2 (FR2), and differential reinforcement of other behavior (DRO) schedules of reinforcement were compared. The response frequency under CRF and FR2 was approximately the same. DRO produced a marked decrease in responding. In Exp. II, a comparison was made of performance under CRF and DRO schedules of light only reinforcement. Light only (projector light with no film) was found to be as effective a reinforcer as film reinforcement. Responding under CRF (light) was maintained at approximately the same level as that obtained in Exp. I under CRF (film). Response frequency decreased under DRO. The behavior of the Ss during the presentation of the film and light reinforcement was markedly different, suggesting a basic difference in the nature of the reinforcing properties of the 2 reinforcers.
