Operant responding in Siamese fighting fish (Betta splendens) as a function of schedule of reinforcement and visual reinforcers.
Journal of the Experimental Analysis of Behavior, 20 (3): 355--362 (November 1973)
Abstract
Trained 4 Siamese fighting fish to emit an operant response that was reinforced by a motion picture film image of another fish. When reinforcement followed every response and when reinforcement was delivered after every 2nd response, the number of responses was higher than during operant level or during extinction. Reinforcement delivered following intervals of no responding (differential reinforcement of other behavior) markedly decreased responding. Light from a projector without film was found to be as effective a reinforcer as film reinforcement. Responding when projector light reinforcement followed every response was maintained at approximately the same level as that obtained under film reinforcement. Responses decreased when only the light was delivered on a differential-reinforcement-of-other-behavior schedule. The behavior of the fish during the presentation of the film was markedly different from their behavior while the projector light was being presented.
