japanese fighting fish vs siamese fighting fishAs with males, ring swimming was acquired and maintained when mirror presentations were instant Experiments 1, 2, and 3 and delayed Experiment 4. The failure of time-honored extinction Experiments 1 and 2 and reaction unbiased mirror shows Experiment 3 to maintain responding proven the reinforcing homes of mirror presentation. These outcomes extend outdated findings of mirror images as reinforcers in males of the same species and illustrate a complementarity among behavioral ecology and the experimental analysis of conduct. The aggressive monitor of male Siamese fighting fish, Betta splendens hereafter, Bettas, is reliably elicited by images of an alternate male Betta. Visual reinforcement of the responding of these males also has been established time and again when such images are presented based on a specified response. In different experiments, visual access to models of other male Bettas Thompson and Sturm, 1965, a live male or female conspecific Rnic, 1977, mirror shows resulting in an image of the fish serving as the experimental subject Lattal and Metzger, 1994; Thompson, 1963, and movie clips of another Betta Turnbough and Lloyd, 1973 all are adequate to broaden and maintain operant responding in male Bettas.
