S. , L. W. , H. L. , Y. Regardless of its survival importance, the aggressive conduct of female Bettas, adding the susceptibility to reinforcement of operant responses ultimate to mirror image presentations, has been shown in the latest experiments to be a competent finding in lots of individuals of the species.
