Effects of visual reinforcer brightness and color on operant behavior of Siamese Fighting Fish

Abstract

The reinforcing effectiveness of models of Siamese Fighting Fish for operant responding of other Siamese Fighting Fish was found to vary as a function of the coloration of the model but not its brightness. Models colored unlike the S were effective reinforcers whereas models colored similar to the S’s coloration were relatively ineffective, confirming an earlier finding. The possible interaction between color and brightness remains unresolved. © 1968, Psychonomic Journals. All rights reserved.
